Background: Hyaluronan, a tumor promoting extracellular matrix polysaccharide, is elevated in malignant epithelial ovarian tumors, and associates with an unfavorable prognosis. To explore possible contributors to the accumulation of hyaluronan, we examined the expression of hyaluronan synthases (HAS1, HAS2 and HAS3) and hyaluronidases (HYAL1 and HYAL2), correlated with hyaluronidase enzyme activity hyaluronan content and HAS1-3 immunoreactivity.Methods: Normal ovaries (n = 5) and 34 serous epithelial ovarian tumors, divided into 4 groups: malignant grades 1+2 (n = 10); malignant grade 3 (n = 10); borderline (n = 4) and benign epithelial tumors (n = 10), were analyzed for mRNA by real-time RT-PCR and compared to hyaluronidase activity, hyaluronan staining, and HAS1-3 immunoreactivity in tissue sections of the same specimens.Results: The levels of HAS2 and HAS3 mRNA (HAS1 was low or absent), were not consistently increased in the carcinomas, and were not significantly correlated with HAS protein or hyaluronan accumulation in individual samples. Instead, the median of HYAL1 mRNA level was 69% lower in grade 3 serous ovarian cancers compared to normal ovaries (P = 0.01). The expression of HYAL1, but not HYAL2, significantly correlated with the enzymatic activity of tissue hyaluronidases (r = 0.5; P = 0.006). An inverse correlation was noted between HYAL1 mRNA and the intensity of hyaluronan staining of the corresponding tissue sections (r = -0.4; P = 0.025).Conclusion: The results indicate that in serous epithelial ovarian malignancies HAS expression is not consistently elevated but HYAL1 expression is significantly reduced and correlates with the accumulation of hyaluronan.

Background: Periodontal tissue damage is mainly caused by the active form of collagenolytic matrix metalloproteinase-8, aMMP-8, the concentration of which in the mouth rinse can be measured with a mouth rinse chairside-test. The mouth rinse chair side test can be used to identify adolescents with a risk of periodontitis., Methods: The data were collected at the Kotka Health Centre (2004-2005, N = 501 and 2014-2015, N = 47) and at the Hämeenlinna Health Centre (2017-2018, N = 125) consisting of adolescents aged 14-17. They underwent a complete periodontal examination, and some were subjected to the aMMP-8-test., Results: We identified bacterial plaques in combination with increased bleeding on probing (BOP), elevated aMMP-8 concentration, smoking and male sex as the main risk factors for initial periodontitis. Approximately 10% of adolescents had subclinical periodontitis, they were not periodontally healthy, but also not sick. They may not develop periodontitis, but they are at the risk. The aMMP-8 test positivity had a stronger association with initial periodontitis than BOP., Conclusions: In addition to identifying risk factors, these adolescents need individual prevention and, if necessary, early treatment. For the periodontal health biomarker aMMP-8, test negativity ([-], ≤20 ng/mL) should be sought.

Background: The link between diabetes and periodontitis is bi-directional: high glucose levels increase the risk of periodontitis and elevated oral fluid aMMP-8 as well as diabetic development while untreated periodontitis worsens glycaemic control., Methods: Type-2 patients (N = 161) underwent an aMMP-8 Point-of-Care Test (POCT) at diabetes clinics. If the test was positive, the patient was sent to an oral health care clinic and oral health examination, health-promoting as well as necessary treatment procedures were carried out. Only 41 patients underwent full clinical evaluations. At the end of the treatment, an aMMP-8 POCT (B) was performed and if the test was positive, the treatment was continued and a new test (C) was performed, aiming for test negativity. The glycated haemoglobin (GHbA1c) test was performed approximately 6 months from the original appointment., Results: GHbA1c concentrations did not decrease during the follow-up. The concentrations of aMMP-8 assessed by POCT, and clinical parameters decreased. Changes in GHbA1c and aMMP-8 levels assessed by POCT during the treatment correlated positively with each other ( p < 0.01)., Conclusion: aMMP-8 POCT proved its reliability, and that its use is beneficial in the diabetes clinic, it enables identifying patients with periodontal findings reliably and guides them directly to an oral health clinic.

Objectives: A freedom of choice pilot provided access to private oral health care services without queuing and with fixed public service-fees for participants in Tampere region, Finland in 2018-2019. The aim of this study was to investigate how use of oral health care services differed by demographics, socioeconomic status, dental fear, and self-reported oral health in this pilot., Material and Methods: SMS-messages including a link to online questionnaire were sent to participants who had booked an appointment, and to those who had not booked an appointment despite registering to pilot. We categorized participants to (1) those who had booked their first appointment before receiving SMS (visitors), (2) those who booked an appointment after receiving the SMS-message (late-visitors), and (3) those who had not booked an appointment during pilot (nonvisitors). We used regression analysis to estimate the association of age, gender, dental fear, economic situation, Oral Health Impact Profile-14-severity (oral health-related quality of life [OHRQoL]), self-reported oral health and need for oral health care (exposures) with oral health care service use during the pilot (outcome)., Results: Out of 2300 participants, 636 (28%) responded. Late-visitors were more likely older and reported more likely need for oral health care, poorer oral health and OHRQoL than visitors or nonvisitors. Nonvisitors were younger and had better OHRQoL than the others. The differences in the service use by gender, economic situation, and dental fear were small., Conclusions: Service use during the pilot depended on the subjective oral health. Our findings highlight the potential of reminders in increasing care use among those with perceived need for services., (© 2022 The Authors.

Objectives: The aim of this follow-up study was to investigate whether adults attend an oral health examination (OHE) based on their individual recall interval (IRI) without a reminder recall system., Methods: The study population included adults who were attending an OHE recommended by their dentists based on their IRI in public oral healthcare clinics of Helsinki City January 1, 2009-December 31, 2009. The inclusion criteria were as follows: alive until the end of IRI, length of the IRI of 12-60 months, and study participants had not been treated successfully by a dental specialist during the IRI period (n = 41,255). We used a multinomial model to identify the factors associated with the timing of OHE. The following predictors were included: oral health indices such as Decayed Teeth and the Community Periodontal Index, the length of the IRI based on an OHE in 2009, age, gender, socioeconomic status, presence of chronic diseases, and emergency appointment. Results were presented as odds ratios with 95% confidence intervals., Results: The OHE based on IRI occurred for 7505 individuals (18.2%) and the OHE was late for 9159 individuals (22.2%). A total of 24,591 (59.6%) adults did not undergo follow-up OHE based on the IRI period of on time or late. Those who came on time for follow-up OHE experienced less caries than those who came later. There was not much difference in periodontal health between the groups. The models indicated that having an emergency appointment was associated with a higher probability of having an OHE. A long IRI (37-60 months) was associated with a higher probability of not participating in OHE even late., Conclusions: It would be beneficial for patients to take appointments based on the recall interval. The results of this study indicated that more needs to be done to increase awareness in the adult population of the benefits and availability of follow-up OHEs based on their IRI in oral healthcare., (© 2022 The Authors.

This study, conducted in a Finnish city, examined whether a long-lasting observed trend in Finnish primary health care, namely, a decreasing rate of office-hour visits to general practitioners (GPs), would lead to reduced services for specific gender, diagnosis or age groups. This was an observational retrospective follow-up study. The annual number of visits to office-hour primary care GPs in different gender, diagnosis and age groups was recorded during a 13-year follow-up period. The effect of the decreasing visit rate on the annual mortality rate in different age and gender groups was also studied. The total number of monthly visits to office-hour GPs decreased slowly over the whole study period. This decrease was stronger in women and older people. The proportion of recorded infectious diseases (Groups A and J and especially diagnoses related to infections of respiratory airways) decreased. Proportions of recorded chronic diseases increased (Group I, cardiovascular diseases, diabetes and osteoarthrosis) during the follow-up. The annual rate of visits to office-hour GP/per GP decreased. There was a decrease in the mortality in two of the age groups (20-64, 65+ years) and no change in the youngest population (0-19 years). The decrease in the office-hours GP activity does not seem to increase mortality either.

The purpose of this study was to investigate whether competition is an effective method to remind primary oral health care dentists to record diagnoses (RRD). The effectiveness of competition was examined in comparison with financial group bonuses (FGBs) and electronic reminders (ERs) of the electronic health record, together with superior-subordinate or development discussions. Putative differences in the diagnosis recording cultures of Finnish public health care physicians and dentists were studied. This was a retrospective quasi-experimental observational study in which the effects of the interventions on the rate of recording diagnoses were identified using a general linear regression model and proportions of visits with recorded diagnoses. The rate of increase in the recording of diagnoses in dentists was 0.995 ± 0.273%/month (mean ± SEM) after the implementation of RRDs and this did not differ from that obtained after starting FGBs (0.919 ± 0.130%/month) or ERs with superior-subordinate or development discussions (1.562 ± 0.277%/month) in physicians. As the rates of increase did not differ none of the applied methods seemed to be more effective than the others when trying to influence the behaviour of primary health care clinicians. Altogether, public primary health care physicians were more active than respective primary oral health care dentists to record diagnoses.

A single-site, randomized clinical trial was designed to determine the efficacy of regular home use of Lumoral ® dual-light antibacterial aPDT in periodontitis patients. For the study, 200 patients were randomized to receive non-surgical periodontal treatment (NSPT), including standardized hygiene instructions and electric toothbrush, scaling and root planing, or NSPT with adjunctive Lumoral ® treatment. A complete clinical intraoral examination was conducted in the beginning, at three months, and at six months. This report presents the three-month results of the first 59 consecutive randomized subjects. At three months, bleeding on probing (BOP) was lower in the NSPT + Lumoral ® -group than in the NSPT group ( p = 0.045), and more patients in the NSPT + Lumoral ® -group had their BOP below 10% (54% vs. 22%, respectively, p = 0.008). In addition, patients in the NSPT + Lumoral ® -group improved their oral hygiene by visible-plaque-index ( p = 0.0003), while the NSPT group showed no statistical improvement compared to the baseline. Both groups significantly reduced the number of deep periodontal pockets, but more patients with a reduction in their deep pocket number were found in the NSPT + Lumoral ® group (92% vs. 63%, p = 0.02). Patients whose number of deep pockets was reduced by 50% or more were also more frequent in the NSPT + Lumoral ® -group (71% vs. 33%, p = 0.01). Patients with initially less than ten deep pockets had fewer deep pockets at the three-month follow-up in the Lumoral ® group ( p = 0.01). In conclusion, adjunctive use of Lumoral ® in NSPT results in improved treatment outcomes at three months post-therapy.

Objectives: Periodontitis is a multifactorial biofilm-induced inflammatory disease; however, clinical and radiographic information reflects events that have already occurred. aMMP-8 lateral-flow chairside or point-of-care-test (POC-test) results have also come to complement the overall status of the patient's current situation. The current study aimed to clarify the usefulness of aMMP-8 chairside-test (aMMP-8 POCT) results to alert the initial or early periodontitis in adolescents, a potential periodontitis risk group with cut off 20 ng/ml in Stage I periodontitis, according to the current periodontitis classification system., Material and Methods: A total of 117 adolescents were aMMP-8 POC tested for aMMP-8 levels and examined for the full mouth and were interviewed for questions concerning health behavior., Results: Of all 117 participants, N = 38 (32.5%) was aMMP-8 POCT positive, and N = 34 (29.1%) had at least one 4 mm periodontal deepened pocket; however, only N = 16 (13.7%) had both characteristics. The subclinical stage (N = 47) could not be classified either as gingivitis or Stage I. Of the participants, who did not have any deepened periodontal pockets, 18  tested negative., Conclusions: Stage I is preceded by antecedent stages that should be tackled by oral healthcare prevention and personalized treatment modalities by professionals. Elevated (>20 ng/ml), positive aMMP-8 POCT results can be regarded as initial alarmer such as emerging risk. This should be utilized in the preventive personalized interventions by oral health professionals., (© 2022 The Authors.

Background: This study, conducted in a Finnish city, examined whether decreasing emergency department (ED) services in an overcrowded primary care ED and corresponding direction to office-hours primary care would modify service usage for specific gender, age or diagnosis groups., Methods: This was an observational retrospective study carried out by gradually decreasing ED services in primary care. The interventions aimed at decreasing use of EDs were a) application of ABCDE-triage combined with public guidance on the proper use of EDs, b) closure of a minor supplementary ED, and finally, c) application of "reverse triage" with enhanced direction of the public to office-hours services and away from the remaining ED The annual number of visits to office-hours primary care GPs in different gender, age and diagnosis groups (International Classification of Diseases (ICD - 10) were recorded during a 13-year follow-up period., Results: The total number of monthly visits to EDs decreased slowly over the whole study period. This decrease was similar in women and men. The decrease was stronger in the youngest age groups (0-19 years). GPs treated decreasing proportions of ICD-10 groups. Recorded infectious diseases (Groups A and J, and especially diagnoses related to infections of respiratory airways) tended to decrease. However, visits due to injuries and symptomatic diagnoses increased., Conclusion: Decreasing services in a primary health care ED with the described interventions seemed to reduce the use of services by young people. The three interventions mentioned above had the effect of making the primary care ED under study appear to function more like a standard ED driven by specialized health care., (© 2022.

Objective: The aim of this study was to investigate the utility of the active matrix metalloproteinase (aMMP-8)-point-of-care (PoC) test as a quantitative real-time chair-side diagnostic tool for peri-implant diagnosis, as well as assess the potentially developing and ongoing risk relative to the traditional clinical methods., Background: Current peri-implant and periodontal disease diagnoses rely on clinical and radiological examinations. This case-control study investigated the applicability of aMMP-8-PoC immunotest for quantitative real-time diagnosis and monitoring of dental implants in health and disease., Methods: Sixty-eight patients visiting a specialist clinic for maintenance following dental implant placement underwent assessment of their peri-implant health. aMMP-8-PoC peri-implant sulcular fluid (PISF) lateral-flow immunotests were performed using ImplantSafe® technology quantitated by ORALyzer®. In addition, the PISF samples were analyzed for total MMP-8, calprotectin, and interleukin (IL)-6 by enzyme-linked immunosorbent assays (ELISA), aMMP-8 by western immunoblot, and MMP-2 and MMP-9 by gelatin zymography., Results: The aMMP-8-PoC test promptly recorded and reflected peri-implant disease, differentiating it clearly from health. X-ray findings (bone loss > 2 mm), peri-implant pocket depth ≥ 3 mm, and bleeding on probing were significantly more prevalent among implants positive for the aMMP-8-PoC test. aMMP-8/ORALyzer analysis was more precise in recording disease than total MMP-8, calprotectin, IL-6, MMP-2, and MMP-9., Conclusions: The aMMP-8-PoC test can be conveniently implemented to alert for and detect active collagenolysis affecting peri-implant tissues, both in the early and advanced stages of the disease. Active and fragmented MMP-8 exhibits a strong and significant association with peri-implantitis as compared to total MMP-8 and other biomarkers and can be utilized as the POC/chairside biomarker of choice in the new classification of peri-implantitis., (© 2022 The Authors.

Background and Objective: Bleeding on probing (BOP) is a widely accepted measure used in periodontal diagnostics. Previous studies suggest that several factors can affect BOP propensity. The aim of this study was to investigate the relative impact of different local and modifying factors on BOP levels., Materials and Methods: The oral health of five hundred and forty-four adolescents (two birth cohorts) aged 15-17 years living in Kotka, Finland, was examined including periodontal probing depth, visible plaque index, root calculus, and BOP. Whole saliva samples were collected and measured for active matrix metalloproteinase-8 (aMMP-8) by time-resolved immunofluorometric assay (IFMA)., Results: Bacterial plaque/calculus accumulation (oral hygiene) had a major influence on BOP levels. The relative impact was several times greater compared with the extent of periodontal pocketing, aMMP-8 levels, smoking, toothbrushing, or gender. Furthermore, BOP levels were significantly elevated among adolescents with poor oral hygiene than good oral hygiene even if adjusted for the extent of periodontal pocketing (P < .001). BOP levels could be low even if several ≥ 4 mm deep periodontal pockets existed. The difference in the extent of periodontal pocketing was not significant between the two birth cohorts of adolescents (P = .731)., Conclusions: BOP levels can be regarded as an important indicator of the extent of bacterial challenge and its adverse effects on the gingival inflammation. However, the level of oral hygiene may mask the association between the extent of gingival bleeding and the severity of the periodontal inflammatory condition. Thus, relying on BOP levels (below 10% or 20%) may provide insufficient information about the periodontal treatment need of an adolescent depending on his/her level of oral hygiene. Yet, more research is needed to confirm the results, also in adult populations., (© 2020 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Objectives: The individualised recall interval (IRI) is part of the oral health examination. This observational, register-based study aimed to explore how oral health indices DMFT (decayed, missing, filled teeth), DT (decayed teeth), CPI (Community Periodontal Index, maximum value of individual was used) and number of teeth are associated with IRI for adults., Methods: Oral health examination includes an assessment of all oral tissues, diagnosis, a treatment plan and assessment and a determination of the interval before the next assessment. It is called the IRI. This cross-sectional study population included 42,533 adults (age range 18-89 years), who had visited for an oral health examination during 2009, provided by the Helsinki City Social Services and Health Care. The recall interval was categorised into an ordinal scale (0-12, 13-24, 25-36 and 37-60 months) and was modelled using a proportional odds model. ORs less than one indicated a shorter recall interval., Results: Recall interval categories in the study population were 0-12 months (n = 4,569; 11%), 13-24 months (n = 23,732; 56%), 25-36 months (n = 12,049; 28%), and 37-60 months (n = 2,183; 5%). The results of statistical models clearly showed an association between the length of recall intervals and oral health indices. In all models, higher values of DMFT, DT and CPI indicated a shorter recall interval. The number of teeth were not so relevant. The association was not influenced when different combinations of other predictors (age, gender, socioeconomic status, chronic diseases) were included in the model. The severity of periodontitis predicted a short recall interval, for example, in the Model 1, CPI maximum value 4 was OR = 0.35 (95% confidence interval 0.31-0.40)., Conclusions: The oral health indices showed a clear association with the length of the IRI. Poor oral health reduced IRI. The indices provide information about the amount of oral health prevention required and are useful to health organisations., (© 2020 The Authors.

Aims: To evaluate the correlation between three commonly used patient-reported outcome measures, two generic and one condition-specific instrument, in assessing the change in health-related quality of life following pelvic organ prolapse surgery., Methods: The generic health-related quality of life measure 15-dimensional instrument (15D), Patient Global Impression of Improvement (PGI-I), and prolapse-specific Pelvic Floor Distress Inventory (PDFI-20) were used to assess the effectiveness of pelvic organ prolapse surgery in the national FINPOP study of 3535 surgeries (83% of all pelvic organ prolapse operations) performed in Finland in 2015. Spearman correlations between PGI-I, change in 15D and its dimensions and change in PFDI-20 and its subscales over a 2-year follow-up were investigated. The proportion of concordant ratings was also studied by investigating the proportion of women rated similarly (worse/no change/better/much better) by two instruments according to validated cutoffs., Results: Among 2248 women for whom the 2-year change in all instruments could be measured, changes in PFDI-20 and 15D and its dimensions were weak (ρ < 0.2 for all except excretion; ρ = 0.39 and sexual activity; ρ = 0.27). PFDI-20 change (ρ = 0.39) and its subscales (ρ = 0.19-0.40, all P < .001) were more strongly correlated with PGI-I. The proportion of fully concordant ratings were higher for PFDI-20 and PGI-I (50.6%) than for PFDI-20 and 15D (33.0%)., Conclusion: The weak correlations between 15D, PGI-I, and PDFI-20 observed in this study show that the quantified health gains are strongly dependent on the chosen patient-reported outcome measures. This demonstrates the importance of using condition-specific sensitive outcome measures in assessing the impact of surgical treatment in pelvic organ prolapse., (© 2020 The Authors.

Introduction: Peptidoglycan recognition protein 1 (PGLYRP1), a member of peptidoglycan recognition proteins, is known to be involved in the proinflammatory response toward bacterial infections. Recently, PGLYRP1 was identified as a ligand for triggering receptor expressed on myeloid cells 1 (TREM-1). Although PGLYRP1 is involved in immune and inflammatory responses, its levels in initial stages of periodontal disease in adolescents are currently unknown., Objectives: We aimed to investigate salivary levels of PGLYRP1 and its correlation with TREM-1, polymorphonuclear leukocyte elastase (PMN elastase), and an active matrix metalloproteinase 8 (aMMP-8) in adolescents., Methods: Whole saliva samples (n = 537) were collected from 15- to 16-y-old adolescents at Kotka Health Center, Finland, prior to periodontal examination, including measurement of periodontal pocket depth (PPD), visible plaque index (VPI), and bleeding on probing (BOP). Adolescents, clustered as periodontally healthy, gingivitis, or subclinical periodontitis, were tested for salivary levels of TREM-1, PGLYRP1, and PMN elastase by enzyme-linked immunosorbent assay and aMMP-8 by a time-resolved immunofluorometric assay (IFMA)., Results: Salivary levels of PGLYRP1 and aMMP-8 were significantly higher in adolescents with subclinical periodontitis and gingivitis compared to individuals with healthy periodontium. TREM-1 and PMN elastase levels were higher in adolescents with subclinical periodontitis compared to healthy individuals but did not reach significance. PGLYRP1 correlated positively with BOP, PPD, VPI, aMMP-8, and TREM-1., Conclusions: Elevated PGLYRP1 levels in adolescents with gingivitis and subclinical periodontitis and its positive correlation with TREM-1 and aMMP-8 may indicate an association of PGLYRP1 with initial stages of periodontal disease. Sex and poor oral hygiene but not smoking are also associated with higher levels of PGLYRP1. However, PGLYRP1 has a lower discriminating capacity and is therefore a less reliable marker alone in the diagnosis of initial stages of periodontal disease in adolescents., Knowledge Transfer Statement: PGLYRP1, a member of peptidoglycan recognition proteins, is a ligand for TREM-1. Elevated PGLYRP1 levels in adolescents with gingivitis and subclinical periodontitis and its positive correlation with TREM-1 and aMMP-8 may indicate an association of PGLYRP1 with initial stages of periodontal disease. However, it has a lower discriminating capacity and is therefore a less reliable marker alone in the diagnosis of periodontal disease in adolescents.

Background: The aim of this study is to investigate if using tobacco products (including snuff, smoking tobacco and dual-using) associates with periodontal health, education level and mortality in a Swedish cohort, hypothesizing that tobacco products affect periodontal health, associate with lower education and increase the risk of death., Method: Study cohort of 1080 subjects aged 31-40 years (528 men, 552 women) was clinically examined and interviewed in 1985 and followed for mortality until 2015. Subjects were classified into two groups: "tobacco users" and "non-users". Associations between periodontal health parameters, tobacco products, education level and age of death were analysed. SPSS was used for analyses., Results: Tobacco products, as well as education level associated, with poor periodontal health. Tobacco users and lower education was linked to higher plaque-, calculus- and gingival-index scores than non-users ( p < 0.001). They also had significantly higher prevalence of deep periodontal pockets (≥5 mm) ( p < 0.001 and 0.010, respectively), missing teeth ( p = 0.010 and 0.003, respectively) and lower education level ( p < 0.001) compared with non-users. However, tobacco product users did not die significantly earlier than non-users., Conclusion: Tobacco products had a negative impact on periodontal health. Tobacco product users were less educated. However, using tobacco products may not cause premature death.

This communication article addresses currently available rapid non-invasive methods to screen and detect periodontitis and dental peri-implantitis. In this regard, oral fluid biomarkers have been researched extensively but self-reported oral health (SROH)-questionnaires have also been developed. Both alternatives may offer a quick and easy way to screen and detect diseased patients. Active matrix metalloproteinase (aMMP-8) is one of the most validated biomarkers for screening and detecting periodontal breakdown related to periodontitis and peri-implantitis and monitoring their treatment effects revealing successful, less- and non-successful treatment results. Currently available aMMP-8 lateral-flow technologies allow this kind of analysis, as demonstrated here, to be conducted quantitatively online and real-time as point-of-care/chairside testing in dental and even medical care settings. In this study, an aMMP-8 peri-implant sulcular fluid point-of-care-test diagnosed peri-implantitis and healthy implants far more accurately than bleeding-on-probing or the other biomarkers, such as polymorphonuclear (PMN)/neutrophil elastase, myeloperoxidase and MMP-9. Although, SROH-questionnaires allow screening in similar settings but they lack the information about the current disease activity of periodontitis and peri-implantitis, which is of essential value in periodontal diagnostics and treatment monitoring. Thus, both methods can be considered as adjunct methods for periodontitis and peri-implant diagnostics, but the value of oral fluid biomarkers analysis does not seem to be substitutable.

Objectives: This study investigates which oral diagnoses public primary dental care dentists record., Methods: An observational register-based retrospective follow-up study was performed in the public primary oral health care of a Finnish town after the dentists were advised to mark the diagnoses in their practices. The rate of recorded diagnoses resulting from visits to the public primary care dentists was studied. The assessed diagnoses were recorded with the 10th revision of the International Classification of Diseases. The distribution of diagnoses was recorded during a 2-year follow-up period., Results: The most frequent diagnosis groups were dental caries (K02, 38.6%), other diseases of dental hard tissues (K03, 14.9%), diseases of pulp and periapical tissues (K04, 11.4%), periodontal diseases (K05, 9.7%), and different types of bone fractures (S02, 8.1%). Periodontitis was underrepresented., Conclusions: In public primary oral health care, there may be difficulties in adequate recording of certain chronic diseases., (© 2020 The Authors.

Background: Patient satisfaction and health-related quality of life are nowadays considered as the most important outcomes of pelvic organ prolapse treatment, and large, prospective clinical studies reporting the patient-reported surgical outcomes are needed., Objective: To evaluate the effect of female pelvic organ prolapse surgery on health-related quality of life and patient satisfaction and to determine predictors of outcome., Study Design: This prospective nationwide cohort study consisted of 3515 women undergoing surgery for pelvic organ prolapse in 2015. The outcomes were measured by validated health-related quality of life instruments (generic 15D, Pelvic Floor Distress Inventory-20, and Patient Global Impression of Improvement) at 6 months and 2 years postoperatively. The baseline predictors of outcomes were studied with logistic regression analysis., Results: In total, 2528 (72%) women were eligible for analysis at 6 months and 2351 (67%) at 2 years. The mean change in the total 15D score suggested a clinically important improvement at 6 months but not at 2 years. However, an improvement in sexual activity, discomfort and symptoms, and excretion was observed during both follow-up assessments. Altogether, 77% and 72% of the participants reported a clinically significant improvement in Pelvic Floor Distress Inventory-20 at the 6-month and 2-year follow-ups, respectively. A total of 84% were satisfied with the outcome and 90% reported an improvement in comparison with the preoperative state with Patient Global Impression of Improvement-I. The strongest predictive factors for a favorable outcome were advanced apical prolapse (adjusted odds ratio, 2.06; 95% confidence interval, 1.58-2.70) and vaginal bulge (1.90, 1.30-2.80). Smoking was associated with an unfavorable outcome as measured by Patient Global Index of Improvement-I (1.69, 1.02-2.81)., Conclusion: Pelvic organ prolapse surgery improved health-related quality of life in 7 of 10 patients over a 2-year follow-up period, and patient satisfaction was high. Apical prolapse beyond the hymen and vaginal bulge were the most consistent predictors for improvement. Our results suggest that patients should be encouraged to stop smoking to avoid an unfavorable outcome., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Purpose: This study aims to validate label-free quantitative proteomics (LFQ) against antibody-based methods for quantifying established periodontal disease biomarkers in saliva., Experimental Design: In an experimental gingivitis model, healthy volunteers (n = 10) provide saliva at baseline (d0), during the induction (d7, d14, d21) and resolution (d35) of gingival inflammation (total n = 50). Biomarker levels are analyzed by LFQ and time-resolved immunofluorometric assay (IFMA) or enzyme-linked immunosorbent assay (ELISA). Molecular matrix metalloproteinase (MMP)-8 forms are assessed by Western blot (WB) analysis., Results: LFQ detects significantly (p < 0.05) elevated MMP-8 (d21vsd7, d35vsd7) and tissue inhibitor of matrix metalloproteinases (TIMP)-1 (d35vsd7). Latent MMP-8 (70-80 kDa) is present (d0-d35), but not active MMP-8 (50-60 kDa). LFQ and immunoassay data significantly correlate for MMP-8 (r = 0.36), myeloperoxidase (r = 0.39), polymorphonuclear leukocyte elastase (r = 0.33), and TIMP-1 (r = -0.24)., Conclusion and Clinical Relevance: LFQ can quantify enzyme levels in saliva, however lacks the ability to measure enzymatic activity. WB analysis reveals that MMP-8 may not be activated during induction of gingival inflammation. Significant but weak correlations between IFMA or ELISA and LFQ suggest a limited capacity of available antibodies to reliably quantify salivary biomarkers for periodontal diseases. Novel "anti-peptide" antibodies designed by newer targeted mass spectrometry-based approaches can help to overcome these drawbacks., (© 2019 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.)

Objectives: This study examined whether using electronic reminders leads to an increase in the rate of diagnosis recordings in the electronic health record system following visits to a general practitioner. The impact of electronic reminders was studied in the primary health care of a Finnish city. Methods: This observational quasi-experimental study based on a before-and-after design was carried out by installing an electronic reminder to improve the recording of diagnoses in the computerized electronic health record system. The quantity of the recorded diagnoses was observed before and after the intervention. The effect of this intervention on the distribution of different diagnoses was also studied. Results: Before intervention, 33%-46% of visits (to general practitioners/month) had recorded diagnose in the primary health care units. After 4 years, the recording rate had risen to 87%-95% (p < 0.001). The rate of change in the recording of diagnoses was highest during the first year of intervention and plateaued about 3.5 years after application reminders. In the present study, most of the visits concerned mild respiratory infections, elevated blood pressure, low back pain and type 2 diabetes. Conclusion: An electronic reminder is likely to improve the recording of diagnoses during the visits to general practitioners. The distribution of diagnoses was in line with former reports concerning diagnoses in Finnish primary care., Competing Interests: Declaration of conflicting interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2020.)

Background: This cross-sectional study aims to investigate if a point-of-care (PoC) test of active matrix metalloproteinase-8 (aMMP-8) predicts levels of inflammation amplifier triggering receptor expressed on myeloid cells-1 (TREM-1) and its putative ligand the neutrophil peptidoglycan recognition protein 1 (PGLYRP1) in saliva., Methods: Forty-seven adolescents, aged 15 to 17 years, were tested with aMMP-8 PoC test, which was followed by a full-mouth clinical examination of the assessment of periodontal, mucosal, and oral health. TREM-1 and PGLYRP1 levels were analyzed by ELISA. The immunofluorometric assay (IFMA) specific for aMMP-8 was used as the reference method., Results: Fourteen saliva samples out of a total of 47 showed positivity for aMMP-8 PoC test. Both the TREM-1 and the aMMP-8 (IFMA) levels were significantly elevated among the aMMP-8 PoC test positives compared with the PoC test negatives (P < 0.05). Moreover, aMMP-8 levels assessed by IFMA showed a strong positive correlation with TREM-1 levels in saliva (r = 0.777, P < 0.001). The number of sites with a probing depth of ≥4 mm was significantly lower among the adolescents that had a negative aMMP-8 PoC test result, and TREM-1 levels < 75 pg/mL (P < 0.05). In contrast, adolescents with a positive aMMP-8 PoC test result (i.e., elevated aMMP-8 levels) together with elevated TREM-1 levels had a significantly higher number of periodontal pockets with ≥4 mm (P < 0.001)., Conclusion: The present study validated usability of aMMP-8 PoC test for predicting "proinflammatory" salivary profile and periodontal health status in adolescents., (© 2019 American Academy of Periodontology.)

This study investigated the diagnostic utility of mouthrinse and saliva in aMMP-8 measurements to analyze patients' risk for active periodontal tissue destruction and progression of periodontal disease among 47 adolescents. Results show that measurements from mouthrinse produce better discrimination and should be used instead of saliva measurements., (Copyright © 2019 Elsevier Inc. All rights reserved.)

We studied oral health in 115 women with and without a history of gestational diabetes (GDM), expecting poorer oral health in the GDM group. Full-mouth examinations were performed 5 years postpartum and the number of teeth, total dental index (TDI) and decayed, missing, filled teeth (DMFT) index were calculated. Bleeding on probing (BOP), probing depth (PD), visible plaque index (VPI), and clinical attachment level (CAL) were recorded. The periodontal inflammatory burden index (PIBI) was calculated. Panoramic radiographs were taken and signs of infections recorded. Oral health habits, symptoms and participants' own opinion of oral health were recorded with questionnaires. At the time of examination, 45% of the women had a history of GDM in the index pregnancy. Mild periodontitis (62%) and bleeding on probing (46%) were common. VPI (13% and 17%, p = 0.009) and PIBI (13.1 and 17.5, p = 0.041) were lower among women with a history of GDM compared with those with no history of GDM. There was no difference between groups in DMFT scores. All women reported good subjective oral health. Thus, contrary to our hypothesis, women with a history of GDM showed better oral health parameters than women without a history of GDM.

Objective: This prospective follow-up cohort study analyzed chronic kidney disease (CKD) patients' oral symptoms, health habits, and oral health-related quality of life (OHRQoL), from predialysis to posttransplantation. A simplified questionnaire method (Oral Health Quality Score, OHQS), based on these and clinical findings, was constructed and tested for identifying patients in need for referral to a dentist., Material and Methods: Fifty-three CKD patients were followed up for a mean of 10.3 years. Clinical oral, radiological, and salivary examination was performed at baseline and posttransplantation. Total Dental Index (TDI) indicating inflammation was calculated. The patients filled out a questionnaire on symptoms, oral hygiene and health care habits, smoking, alcohol use, and medication. General health-related quality of life was assessed with the 15-dimensional (15D) instrument at posttransplantation. Descriptive and analytical methods were used in statistics., Results: OHQS significantly correlated with high TDI (p = 0.017), number of teeth (p = 0.031), and unstimulated salivary flow rate (p = 0.001) in transplanted patients. Number of daily medications showed a negative correlation with the OHQS (r = - 0.30; p = 0.028). The prevalence of oral symptoms was slightly, but not significantly, more common posttransplantation compared with predialysis stage., Conclusion: OHQS identified patients with high oral inflammatory score thus confirming our study hypothesis., Clinical Relevance: Use of OHQS and measuring salivary flow indicate patients at risk for oral diseases. These markers might be easy to use chair-side also by auxiliary personnel.

Background: The aim of this study was to investigate how different patient-related risk indicators might be associated with the odds of developing subclinical periodontitis in adolescents., Methods: This cross-sectional study included 252 Finnish individuals aged 15 to 16 years, of whom 141 were boys and 111 girls. A specially trained dentist performed clinical examinations: measurements included periodontal indexes (bleeding on probing, visible plaque index, root calculus, and probing depth, smoking by pack-years, periodontal bacteria (Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Prevotella intermedia, Prevotella nigrescens, and Treponema denticola) and the potential salivary periodontal biomarkers (active matrix metalloproteinase-8 [aMMP-8], polymorphonuclear leukocyte elastase [PMN elastase], and total protein, albumin, immunoglobulin A, immunoglobulin G, and immunoglobulin M). Results were analyzed by ordinal logistic regression, one-way analysis of variance, Fisher exact test, and Kruskal-Wallis H test., Results: The main finding of this study was that subclinical periodontitis in adolescents was statistically significantly associated with elevated salivary aMMP-8 but not with PMN elastase. Also, adolescents with subclinical periodontitis had statistically significantly higher levels of bleeding on probing, root calculus, and dental plaque than adolescents without subclinical periodontitis., Conclusions: We suggest that the main risk factor for subclinical periodontitis in adolescents is the partly calcified, dysbiotic bacterial biofilm, which interacts with the immune defenses of the host; this leads to gingival inflammation and eventually to deepening periodontal pockets. This proinflammatory subclinical periodontitis stage, which represents stage I periodontitis in the new classification, is reflected as elevated salivary aMMP-8 levels in oral fluids., (© 2018 American Academy of Periodontology.)

Introduction: The management of pelvic organ prolapse (POP) varies significantly between countries. The objective of this study was to describe the methods used for POP surgery in Finland and to identify the factors that affect clinicians' choice to use either a native tissue repair (NTR) or a mesh repair method., Material and Methods: This prospective cohort study included 3535 surgeries covering 83% of all POP operations performed in Finland in 2015. The operative details and patient characteristics, including the Pelvic Floor Distress Inventory (PFDI-20), were compared between three selected surgical methods: NTR, transvaginal mesh (TVM) and abdominal mesh (AM). The predictive factors for the use of mesh augmentation were also studied with logistic regression analysis., Results: The most common method was NTR (n = 2855, 81%), followed by TVM (n = 429, 12%) and AM (n = 251, 7%). Approximately 92% of the patients who underwent primary prolapse surgery underwent NTR, and mesh surgery was used mainly for recurrent prolapse. The strongest predictor of mesh surgery was previous POP surgery for the same vaginal compartment (adjusted odds ratio [OR] = 56, 95% confidence interval [CI] = 38-84 for TVM; adjusted OR = 22, 95% CI = 14-34 for AM). Other predictive factors for mesh surgery were previous hysterectomy, healthcare district, severe bulge symptoms and advanced prolapse. TVM was associated with advanced anterior prolapse and older age. AM surgery was associated with advanced apical and/or posterior compartment prolapse. PFDI-20 scores were the highest in the AM group (108 vs 103 in the TVM group and 98 in the NTR group, P = 0.012), which indicates more bothersome symptoms than in the other groups., Conclusions: The Finnish practices follow international guidelines that advocate NTR as the principal surgical method for POP. Synthetic mesh augmentation was mainly used in patients with recurrent and advanced prolapse with severe symptoms. The variation in the rates of mesh augmentation for POP surgery in different hospitals implies a lack of sufficient evidence of the most suitable treatment method and indicates a need for national guidelines., (© 2018 Nordic Federation of Societies of Obstetrics and Gynecology.)

This cross-sectional study compares the effectiveness of an active MMP-8 (aMMP-8) point-of-care (PoC)/chairside mouthrinse test to the conventional bleeding on probing (BOP) (cutoff 20%) test in detecting subclinical periodontitis/pre-periodontitis in Finnish adolescents. The study was carried out at the Kotka Health Center, Finland. A total of 47 adolescents (30 boys/17 girls) aged 15⁻17 were first tested with the aMMP-8 PoC test, followed by a full-mouth evaluation of clinical parameters of oral health including periodontal, oral mucosal, and caries assessment. A periodontist performed these clinical examinations. The aMMP-8 PoC test result had much stronger association with subclinical periodontitis than the BOP 20% test (2.8⁻5.3 times stronger in terms of odds ratio). The aMMP-8 PoC test had ≥2 times higher sensitivity than the BOP 20% test with, generally, the same specificity. Further, the aMMP-8 PoC test had generally better accuracy and lower false negative percentages. The aMMP-8 PoC test seemed to be more effective than the conventional BOP test in detecting subclinical periodontitis/pre-periodontitis in adolescents reducing the risk of their undertreatment. However, the sample size may be a limiting factor, and more studies are needed to confirm our results for both adolescents and adults.

Objective: To investigate the impact of anti-rheumatic medications on salivary matrix metalloproteinase (MMP)-8 levels and MMP-8/TIMP (tissue inhibitor of MMPs)-1 ratio in patients with rheumatoid arthritis (RA) and periodontal findings during a 1-year follow-up., Materials and Methods: Salivary MMP-8 was measured by an immunofluorometric assay and TIMP-1 by an enzyme-linked immunosorbent assay of 53 patients with early untreated RA (ERA), naïve to synthetic disease modifying anti-rheumatic drugs (DMARDs), of 28 patients with chronic RA (CRA), candidates for biologic DMARDs and of 43 age- and sex-matched controls. Periodontal health was evaluated by bleeding on probing (BOP), pocket depth (PD), and periodontal inflammatory burden index (PIBI). Examinations were conducted twice for RA patients and once for controls., Results: Salivary MMP-8 level and MMP-8/TIMP-1 ratio associated positively with PIBI in patients with chronic RA (MMP-8: p < 0.001 at baseline, p = 0.002 after follow-up; MMP-8/TIMP-1 ratio p < 0.001, p = 0.003, respectively) and in controls (MMP-8: p = 0.010, MMP-8/TIMP-1 ratio: p = 0.010). Salivary MMP-8 levels were highest at the early stage of RA. The used DMARDs, synthetic or biologic, did not affect salivary MMP-8 concentrations., Conclusions: The use of synthetic or biologic DMARDs did not affect salivary MMP-8 levels in RA patients regardless the duration of RA., (© 2018 John Wiley & Sons A/S.

Traditional periodontal disease diagnostics are based mainly on clinical examination and radiographs. They assess only past tissue destruction and provide no information on the current disease status or its future progression. The objective is to find out if an active matrix metalloproteinase-8 (aMMP-8) point-of-care (PoC) test could provide a cost-effective way to get around this limitation. This cross-sectional study used 47 adolescents and 70 adults, who were clinically examined and their aMMP-8 PoC tested. The aMMP-8 PoC test results and patients' treatment need, based on the community periodontal index of treatment needs (CPITN), were compared and analyzed using Fisher's exact test. In terms of CPITN, the aMMP-8 PoC test gave no false positives for both adolescents and adults. All healthy patients got a negative test result, while a positive test result indicated periodontal treatment need correctly. Finally, there was a significant association between a patient's aMMP-8 PoC test result and his/her treatment need ( p = 0.001 for adolescents, p = 0.001 for adults). In conclusion, more accurate diagnostics of periodontal diseases' activity and progression using an aMMP-8 PoC test may help to reduce oral health care costs by reducing patient overtreatment, improving patient outcome, and reducing the need for complex periodontal therapy.

To study oral health in patients with rheumatoid arthritis (RA) with emphasis on disease activity and treatment of RA. In this prospective cohort study 81 RA patients [53 early untreated RA (EURA) and 28 chronic RA (CRA) patients with inadequate response to synthetic disease modifying antirheumatic drugs (DMARDs)], underwent rheumatological [Disease Activity Score (28-joint) DAS28] and dental examinations [Total Dental Index (TDI), Decayed Missing Filled Teeth (DMFT) and Decayed Missing Filled Surfaces (DMFS)]. For controls, 43 volunteers were examined. After the examinations, EURA patients started treatment with synthetic DMARDs, oral and intra-articular glucocorticoids. CRA patients were candidates for biological DMARDs. The patients were re-examined mean 16 months later. Results were analyzed with descriptive statistics and logistic regression. TDI was higher in both RA groups at baseline compared to controls [EURA: 2 (2-3); CRA: 2 (1-3); controls 1 (1-3), p = 0.045]. DMFT [r s 0.561 (p = 0.002)] and DMFS [r s 0.581 (p = 0.001)] associated with DAS28 at baseline in CRA patients. After follow-up, DAS28 associated positively with DMFT [r s 0.384 (p = 0.016)] and DMFS [r s 0.334 (p = 0.038)] in EURA patients; as well as in CRA patients DMFT [r s 0.672 (p = 0.001)], DMFS [r s 0.650 (p = 0.001)]. RA patients already in the early phase of the disease had poorer oral health compared to controls. The caries indices associated with the activity of RA in both patient groups. Oral status may thus contribute to the development and further relate to the activity of RA.

The analysis of the disease-specific oral and systemic biomarkers in saliva and oral fluids (i.e., mouth rinse, gingival crevicular fluid (GCF), and peri-implantitis fluid (PISF)) is demanding. Several hosts and microbial factors may influence their expression, release, and levels. The type of saliva/oral fluids utilized for the diagnostics affects the analysis. High sensitivity and specificities together with sophisticated methods and techniques are essential for valuable outcome. We describe here recently developed practical, convenient, inexpensive, noninvasive, and quantitative mouth rinse and PISF/GCF/chair-side/point-of-care (PoC) lateral-flow aMMP-8 immunoassays (PerioSafe and ImplantSafe/ORALyser) to detect, predict, and monitor successfully the course, treatment, and prevention of periodontitis and peri-implantitis, respectively. The tests have been independently and successfully validated to differentiate periodontal and peri-implant health and disease in Finland, Germany, Netherland, Sweden, Turkey, Nigeria, Malawi, and USA. The clinical use of salivary/oral fluid biomarkers to identify oral and systemic conditions requires additional studies utilizing these noninvasive screening, diagnostic, and preventive aMMP-8 PoC/chair-side technologies.

Objective: To study prospectively the association of salivary and serum matrix metalloproteinase (MMP)-8, tissue inhibitor of MMPs (TIMP)-1 and interleukin (IL)-6 with periodontal and systemic inflammation in rheumatoid arthritis (RA). We hypothesized that biomarker concentrations reflect inflammation., Methods: Fifty three early untreated RA (ERA) and 28 chronic RA (CRA) patients, underwent rheumatological and dental examinations at baseline and one year later after starting first conventional or biological disease modifying antirheumatic drug. We included 43 control subjects. Saliva and serum samples were analyzed for MMP-8, TIMP-1 and IL-6. Periodontal health was assessed by bleeding on probing (BOP), pocket depth (PD) and periodontal inflammatory burden index (PIBI); RA disease activity was assessed by disease activity score DAS28. Joint destruction was analyzed by the modified Sharp-van der Heijde (SHS) method., Results: Serum MMP-8 (p < .001; p < .001) and IL-6 (p < .001; p = .002) were significantly higher in CRA vs. other study groups during the study. Salivary MMP-8 (p = .010) and IL-6 (p = .010) were significantly higher in ERA vs. other study groups at baseline. Salivary MMP-8 was associated with periodontal parameters., Conclusion: Elevated serum concentrations of MMP-8 and IL-6 in CRA patients reflected chronic RA, while elevated salivary concentrations of MMP-8 levels in ERA patients reflected increased periodontal inflammation. Key messages Concentrations of inflammatory biomarkers in serum and saliva were different between patients with RA and healthy controls. Concentrations of MMP-8 and of IL-6 in serum were elevated in patients with chronic RA reflecting joint inflammation and the burden of established RA. Concentrations of MMP-8 in saliva was elevated already at the early stage of RA and the level of salivary MMP-8 was associated with poor periodontal health both in patients with early and in those with chronic RA.

Introduction: We studied whether primary care teams respond to financial group bonuses by improving the recording of diagnoses, whether this intervention leads to diagnoses reflecting the anticipated distribution of diseases, and how the recording of a significant chronic disease, diabetes, alters after the application of these bonuses., Methods: We performed an observational register-based retrospective quasi-experimental follow-up study with before-and-after setting and two control groups in primary healthcare of a Finnish town. We studied the rate of recorded diagnoses in visits to general practitioners with interrupted time series analysis. The distribution of these diagnoses was also recorded., Results: After group bonuses, the rate of recording diagnoses increased by 17.9% (95% CI: 13.6-22.3) but not in either of the controls (-2.0 to -0.3%). The increase in the rate of recorded diagnoses in the care teams varied between 14.9% (4.7-25.2) and 33.7% (26.6-41.3). The distribution of recorded diagnoses resembled the respective distribution of diagnoses in the former studies of diagnoses made in primary care. The rate of recorded diagnoses of diabetes did not increase just after the intervention., Conclusions: In primary care, the completeness of diagnosis recording can be, to varying degrees, influenced by group bonuses without guarantee that recording of clinically significant chronic diseases is improved.

Objectives: The aim of this longitudinal study was to compare the oral health of chronic kidney disease patients at the predialysis (baseline) and post-transplantation (follow-up) stages and to investigate differences in oral health between diabetic nephropathy and other kidney disease patients at follow-up., Materials and Methods: Fifty-three kidney disease patients (34 men) aged 31-86 years were followed up to 157 months. Clinical and radiological oral examinations, salivary and laboratory analyses, and oral health behavior questionnaires were conducted at the predialysis and follow-up stages at Helsinki University Hospital, Finland. Oral inflammatory burden was estimated by calculating deep periodontal pockets, periodontal inflammatory burden (PIBI), decayed, missing, and filled teeth (DMFT), and total dental indices (TDI). Results were analyzed using cross-tabulation Pearson chi-square or Fisher's exact test and the Mann-Whitney U test, and the McNemar and Wilcoxon signed-rank test., Results: At the predialysis stage, patients more often had calculus and deep periodontal pockets; TDI, PIBI, number of teeth, and salivary flow rates were also statistically significantly higher compared to follow-up. At follow-up, diabetic nephropathy patients more often had Candida growth, more plaque, and used more drugs and had lower stimulated salivary flow than patients with other kidney diseases., Conclusion: Oral health was better at follow-up than at the predialysis stage; however, attention should be given to the lower salivary flow rate and higher number of drugs used at that stage., Clinical Relevance: This study confirms the importance of treating oral infectious foci at the predialysis stage in order to prevent adverse outcomes after kidney transplantation.

Background: Triggering receptor expressed on myeloid cells (TREM-1) is a cell-surface receptor involved in amplification of inflammatory response to bacterial infections, along with its ligand peptidoglycan recognition protein 1 (PGLYRP1). TREM-1 is shed by matrix metalloproteinases (MMPs) to its soluble (s) form. The aim of the study is to investigate association of sTREM-1 and PGLYRP1 with oral inflammatory burden among patients with chronic kidney disease (CKD) at predialysis and posttransplantation stages., Methods: One hundred forty-four patients with CKD were examined at predialysis, and oral infection foci were treated prior to kidney transplantation. Fifty-three patients were available for follow-up after transplantation. Oral inflammatory burden was assessed by the Periodontal Inflammatory Burden Index (PIBI) and Total Dental Index. sTREM-1, PGLYRP1, and interleukin (IL)-1β were measured in saliva by enzyme-linked immunosorbent assay, and MMP-8 was measured by immunofluorometric assay., Results: In the predialysis stage, sTREM-1 and PGLYRP1 were positively associated with IL-1β, MMP-8, and PIBI. More specifically, patients with deeper probing depth (PD) (at least two sites with ≥6 mm) had higher concentrations of salivary sTREM-1 and PGLYRP1 compared with those with shallower PD. Higher concentrations of PGLYRP1 and IL-1β were associated with a higher number of teeth (> 25). On follow-up, higher PGLYRP1 and sTREM-1 were associated with one or more sites with ≥4 mm PD., Conclusions: sTREM-1 and PGLYRP1 are elevated in patients with CKD with poor oral health and positively correlate with number of active periodontal pockets after oral infection therapy. Moreover, they positively correlate with MMP-8 and IL-1β. Hence, the salivary sTREM-1/PGLYRP1 axis could be useful as a diagnostic marker for oral infection within patients with CKD., (© 2017 American Academy of Periodontology.)

Oral infections up-regulate a number of systemic inflammatory reactions that, in turn, play a role in the development of systemic diseases. We investigated the association between oral health and autoimmune diseases in a cohort of Swedish adults. Hypothesis was that poor oral health associates with incidence of autoimmune diseases. Overall 1676 subjects aged 30-40 years old from Stockholm County (Sweden) participated in this study in 1985. Subjects were randomly selected from the registry file of Stockholm region and were followed-up for 30 years. Their hospital and open health care admissions (World Health Organization ICD 9 and 10 codes) were recorded from the Swedish national health registers. The association between the diagnosed autoimmune disease and the oral health variables were statistically analyzed. In all, 50 patients with autoimmune diagnoses were detected from the data. Plaque index was significantly higher in the autoimmune disease group (≥median 35 (70%) vs. ˂median 872 (54%), p = 0.030). No statistical difference was found in gingival index, calculus index, missing teeth, periodontal pockets, smoking or snuff use between patients with and without autoimmune disease. Our study hypothesis was partly confirmed. The result showed that subjects with a higher plaque index, marker of poor oral hygiene, were more likely to develop autoimmune diseases in 30 years., Competing Interests: The authors declare no conflicts of interests regarding the publication of this article.

Objectives: To investigate Finnish dentists' smoking cessation related attitudes, consultation practices and familiarity with the local treatment guideline on smoking cessation., Basic Research Design: An online questionnaire was sent to 1740 dentists, which corresponds to 39% of dentists in Finland. A total of 456 dentists responded (response rate 26%), of whom 435 (95%) were clinicians. The dentists' smoking cessation practices were also compared to ones reported in a previous study in Finnish physicians., Results: Dentists found smoking cessation important and often discussed and recommended quitting to the patients, but concrete withdrawal actions were seldom provided. The local treatment guideline on smoking cessation was actively utilized by 36% of the dentists. Adherence to the guideline was associated with higher rates of smoking cessation activities and success in them. Smoking cessation activity among dentists was significantly lower than in Finnish physicians. In accordance with the literature, among dentists, the most common barriers for smoking cessation were lack of time (44%) and education (42%)., Conclusion: Although smoking cessation is discussed with patients, dentists are less active in taking concrete actions to support the patient on withdrawal. Adherence to the local treatment guideline was associated with better capabilities in dealing with tobacco withdrawal and a more active role in smoking cessation. The results suggest that more education on the local smoking cessation treatment guideline and cessation intervention is needed in order to overcome the remaining barriers to promoting effective smoking cessation in dental practice., (Copyright© 2017 Dennis Barber Ltd.)

Objective: Oral lichen planus (OLP) and lichenoid lesions (OLL) are regarded as precursor lesions of oral squamous cell carcinoma (OSCC) with potential for malignant transformation. This potential is not clear due to difficulties in diagnosis of OLP and OLL. Our aim was therefore to evaluate previously identified OLP and OLL as precursor lesions in OSCC and to identify cancer related etiological factors such as smoking and alcohol consumption., Material and Methods: We retrospectively reviewed all cases (total 323, comprising 164 females and 159 males) with OSCC treated at the Department of Oral and Maxillofacial Diseases and Surgery, Helsinki University Hospital during 2015. Confirmed by histopathological biopsy, 58 (17.9%) had OLP and 13 had OLL (4.0%) as precursor lesion., Results: Patients with OLP were slightly older than those without it. OLP was more common in females than in males (p < .0001). TN class 1 tumors were more prevalent among patients with OLP or OLL (p = .006) and cancer relapses less common (p = .005). Smoking was less frequent in patients with OLP and OLL (p < .0001). Also alcohol abuse was less frequent among these patients (p < .001)., Conclusion: Our findings confirm the importance of active follow-up of all patients with OLP and OLL even in patients who do not fit a traditional high-risk category for OSCC.

Introduction: Periodontitis is a multifactorial infectious disease of the supporting tissues of teeth in which bacterial, genetic and lifestyle factors such as smoking have an important role., Aim: The aim was to examine if Bleeding On Probing (BOP ≥ 20%) and ≥ 4 mm deep pockets correlated with any suspicion of initial radiological findings of periodontitis and bone loss. We also investigated whether any pro-inflammatory-related candidate Single Nucleotide Polymorphisms (SNPs) were associated with any suspicion of radiological findings., Materials and Methods: Altogether 47 generally healthy adolescent patients of one birth cohort had given their approval for their saliva samples to be used for DNA analysis. One participant was excluded after discrepant gender check. An oral radiologist analysed right and left bitewing radiographs of 47 patients. Clinical parameters such as BOP ≥ 20%, ≥ 4 mm pockets, Visible Plaque Index of all teeth (VPI%), as well as smoking habits were recorded. DNA was extracted and 71 SNPs from candidate genes for initial periodontitis were genotyped. The association between ≥ 4 mm pockets and BOP ≥ 20% with radiological findings and selected SNPs was modelled using logistic regression., Results: Variants in Toll-Like Receptors 4 (TLR4) gene (rs498670) (OR=5.8, {CI95% 1.6-20.7}, p=0.02, FDR q-value=0.13) and TNFSF11 gene (rs2277438, OR=0.3 {CI95% 0.1-0.9}, p=0.002, FDR q-value=0.56) were associated with any suspicious radiological findings; however the significance vanished after False Discovery Rate analysis (FDR). The association between BOP ≥ 20% and any radiographic signs of periodontitis was found to be statistically significant, OR=1.6, CI 95% 1.0-2.4, p=0.04., Conclusion: Only TLR4 (rs498670) and TNFSF11 (rs2277438) genes were found to have a positive correlation with radiological findings suggestive of initial periodontitis after adjustment for smoking and visible plaque.

Background: Although several validated generic health-related quality of life instruments exist, disease-specific instruments are important as they are often more sensitive to changes in symptom severity. It is essential to validate the instruments in a new population and language before their use. The objective of the study was to translate into Finnish the short forms of three condition-specific questionnaires (PFDI-20, PFIQ-7 and PISQ-12) and to evaluate their psychometric properties in Finnish women with symptomatic pelvic organ prolapse., Methods: A multistep translation method was used followed by an evaluation of validity and reliability in prolapse patients. Convergent and discriminant validity, internal consistency and reliability via test-retest were calculated., Results: Sixty-three patients waiting for prolapse surgery filled the three questionnaires within two weeks. Response rate for each item was high in PFDI-20 and PISQ-12 (99.8 and 98.9% respectively). For PFIQ-7 response rate was only 60%. In PFIQ-7, six respondents (9.5%) reached the minimum value of zero showing floor effect. None of the instruments had ceiling effect. Based on the item-total correlations both PFIQ-7 and PFDI-20 had acceptable convergent validity, while the convergent validity of PISQ-12 was lower, r = 0.138-0.711. However, in this instrument only three questions (questions 6, 10 and 11) had r < 0.3 while others had r ≥ 0.380. In the test-retest analysis all the three instruments showed good reliability (ICC 0.75-0.92). Similarly, the internal consistency of the instruments, measured by Cronbach's α, was good (range 0.69-0.96) indicating high homogeneity., Conclusions: Finnish validated translation of the PFDI-20 and PISQ-12 have acceptable psychometric properties and can be used for both research purposes and clinical evaluation of pelvic organ prolapse symptoms. The Finnish version of PFIQ-7 displayed low response rate and some evidence of a floor effect, and thus its use is not recommended in its current form.

Background: In periodontitis, genetics and smoking play important roles in host immune system response. The aim of this study is to determine whether the genetic background of initial periodontitis and caries could be detected using an active matrix metalloproteinase (aMMP)-8 chairside test in Finnish adolescents., Methods: Forty-seven participants gave approval for analysis of both oral fluid collection and DNA. An aMMP-8 chairside test was performed on participants (adolescents aged 15 to 17 years), and full-mouth clinical parameters of oral health were assessed including periodontal, oral mucosal, and caries status in Eastern Finland from 2014 to 2015. DNA was extracted from oral fluid samples and genotyped for 71 polymorphisms in 29 candidate genes for periodontitis. Results were analyzed using a logistic regression model. P values were corrected for multiple testing using false discovery rate (<0.05)., Results: aMMP-8 chairside test positivity and three or more ≥4 mm pockets were associated with vitamin D receptor (VDR) (rs2228570, P = 0.002, q = 0.04) and MMP3 (rs520540, rs639752, rs679620, P = 0.0009, 0.003, 0.003, q = 0.04, respectively). None of the other single-nucleotide polymorphisms studied showed a significant association with the aMMP-8 chairside test and at least one caries lesion positivity., Conclusion: Genetic polymorphisms of MMP3 and VDR are linked to initial periodontitis in Finnish adolescents, and the aMMP-8 chairside test can eventually detect initial periodontitis in young patients with predisposing genetic background.

Objective: To examine the association between postmenopausal hormone therapy (HT) and Alzheimer's disease (AD)., Methods: Medicine and Alzheimer's disease (MEDALZ) is a nested case-control study of the entire Finnish population with clinically verified AD from 2005 to 2011 and up to 4 matched controls per case. This study comprises 230,580 women (46,117 cases and 184,463 controls). Data on HT use from 1995 to 2011 was extracted from the national prescription register using following ATC codes: G03C (estrogen), G03D (progestogen) and G03F (estrogen and progestogen in combination). Only systemic HT (oral or transdermal) was considered., Results: Use of systemic estrogen and progestogen was associated with an increased risk of AD, with ORs (95% CI) of 1.10 (1.06-1.12) and 1.13 (1.10-1.17) respectively, but use of systemic estrogen HT for >10years (OR, 95% CI: 0.91, 0.84-0.99) was protective against AD. Long-term (>10years) use of progestogen and combination HT was not related to AD risk (OR, 95% CI: 1.0, 0.90-1.2)., Conclusion: Our findings do not suggest HT is an important determinant of AD risk., (Copyright © 2017 Elsevier B.V.

Background: This study evaluates levels of matrix metalloproteinase (MMP)-8, MMP-9, and tissue inhibitor of MP-1 (TIMP-1) in biofluids of women with gestational diabetes mellitus (GDM) and systemically healthy counterparts with different statuses of periodontal health., Methods: Seventy-one women with GDM and gingivitis (Gg), 30 women with GDM and healthy periodontium (Gh), 28 systemically and periodontally healthy women (Hh), and 37 systemically healthy women with gingivitis (Hg) were evaluated. MMP-8, MMP-9, and TIMP-1 levels were determined in gingival crevicular fluid (GCF), saliva, and serum by immunofluorometric and enzyme-linked immunosorbent assays. Full-mouth clinical periodontal parameters were recorded., Results: GCF and serum MMP-8 concentrations, serum MMP-9 concentrations, and serum MMP-8/MMP-1 and MMP-9/MMP-1 molar ratios were significantly higher in Gg compared with Hg group (P <0.05). Serum MMP-8 levels and salivary TIMP-1 levels were higher in Gh compared with Hg group (P <0.05) whereas salivary MMP-8/TIMP-1 molar ratio was lower in Gh compared with Hg group (P <0.05). Elevated concentrations of GCF MMP-8 and MMP-9 were found in Gg compared with Gh group (P <0.05). Significant correlations were found between local levels of biomarkers and clinical periodontal parameters in only GDM group., Conclusion: GDM may modulate both local and circulating levels of MMP-8 especially when associated with gingivitis.

Objectives: To investigate the association between rheumatoid arthritis (RA) and periodontitis with special emphasis on the role of antirheumatic drugs in periodontal health., Design: Prospective follow-up study. Patients with early untreated RA and chronic active RA were examined at baseline and 16 months later. Controls were examined once., Settings and Participants: The study was conducted in Finland from September 2005 to May 2014 at the Helsinki University Hospital. Overall, 124 participants were recruited for dental and medical examinations: 53 were patients with early disease-modifying antirheumatic drug (DMARD) naїve RA (ERA), 28 were patients with chronic RA (CRA) with insufficient response to conventional DMARDs. After baseline examination, patients with ERA started treatment with synthetic DMARDs and patients with CRA with biological DMARDs. Controls were 43 age-matched, gender-matched and community-matched participants., Outcome Measures: Degree of periodontitis (defined according to the Center for Disease Control and Prevention and the American Academy of Periodontology). Prevalence of periodontal bacteria (analysed from plaque samples), clinical rheumatological status by Disease Activity Score, 28-joint count (DAS28), function by Health Assessment Questionnaire (HAQ) and treatment response by European League Against Rheumatism (EULAR) criteria., Results: Moderate periodontitis was present in 67.3% of patients with ERA, 64.3% of patients with CRA and 39.5% of control participants (p=0.001). Further, patients with RA had significantly more periodontal findings compared with controls, recorded with common periodontal indexes. In the re-examination, patients with RA still showed poor periodontal health in spite of treatment with DMARDs after baseline examination. The prevalence of Porphyromonas gingivalis was higher in patients with ERA with periodontal probing depth ≥4 mm compared with patients with CRA and controls. Antirheumatic medication did not seem to affect the results., Conclusions: Moderate periodontitis was more frequent in patients with RA than in controls. Patients with ERA and CRA exhibited poorer periodontal health parameters when compared with controls. There was no association between antirheumatic treatment and periodontal parameters., Competing Interests: Competing interests: None declared., (Published by the BMJ Publishing Group Limited.

Human saliva is an easily accessible biological fluid and contains a variety of disease-related biomarkers, which makes it a potential diagnostic medium. The clinical use of salivary/oral fluid biomarkers to identify oral and systemic conditions requires the development of non-invasive screening and diagnostic technologies, and is among the main goals of oral fluid researchers. The analysis of the disease-specific oral and systemic biomarkers in saliva and oral fluids (i.e., mouth-rinse, gingival crevicular fluid (GCF) and peri-implantitis sulcular fluid (PISF)) is demanding. Several factors influence their expression and release; these factors include the intracellular location, the molecular size and the flow characteristics of the biological fluid. The type of saliva/oral fluid utilized for the diagnostics affects the analysis. High sensitivity together with sophisticated methods and techniques are essential to get a useful outcome. We describe here a recently developed mouth-rinse that is practical, convenient and inexpensive, as well as PISF chair-side/point of care (PoC) lateral-flow active matrix metalloproteinase (aMMP-8) immunoassays to detect, predict and monitor the course and treatment of periodontitis and peri-implantitis.
