Objective: This study aimed to gain knowledge of general oral health preventive measures with a specific focus on root caries preventive measures for patients ≥65 years old, performed by Norwegian dental hygienists in public and private dental health services. A secondary aim was to investigate differences and challenges in prevention practices. Materials and methods: An electronic survey was conducted among the sample in 2022. A total of 365 dental hygienists were included in the analyses. Chi-square tests were used to analyze differences between private and public dental hygienists regarding preventive measures and perceived challenges. Results: The most frequently reported general oral health preventive measures were oral hygiene instruction, professional tooth cleaning and scaling. Oral hygiene instruction and application of fluoride varnish were the most performed root caries preventive measure, and reduced manual dexterity in patients was the most perceived challenge. Public dental hygienists perceived challenges to a greater extent than private dental hygienists, particularly related to reduced mobility and ergonomic difficulties in patients. Conclusion: This study confirms dental hygienists’ important role in oral health promotion and showed that Norwegian dental hygienists performed a wide range of preventive measures for patients ≥65 years old. However, a number of challenges were identified in the preventive work.

Objectives: Dental erosion has evolved into a common condition with growing concern in the dental community. The aim of this study was to explore the protective effects of two highly fluoridated products, silver fluoride solution (silver diamine fluoride-potassium iodide solution, SDF-KI) and fluoride varnish, on dental erosion in mouse. Methods: Two groups of ten young CD-1 mouse were given a cola drink ad libitum over a 6-week period. A prophylactic treatment with a silver fluoride solution (38% SDF 48,000 ppm F with a silver concentration of 253,900 ppm) and a fluoride varnish (NaF, 22,600 ppm F) were applied on the mandibular molars, performed under sedation twice a week during the whole experiment. Furthermore, two control groups of ten mice were included, a positive (cola drink) and a negative (distilled water) control. A terminal procedure was followed by dissection of mandibular molars and analysis of them using scanning electron microscopy (SEM). The first molars were transversely ground, further analyzed by SEM, and measured for tooth height and tooth tissue loss. Results: Analyses of mandibular molars treated with a fluoride varnish indicated a 5% decreased tooth tissue loss, compared to the molars which served as a positive control. The best effect was achieved with the application of silver fluoride solution, displaying a 35% decreased tooth tissue loss compared to the positive control group. Conclusions: Preventive treatment with a solution of silver fluoride solution exhibits greater protection against dental erosion compared to a traditional fluoride varnish. This study indicates that silver fluoride solution is an effective fluoride compound and is highly beneficial in a clinical setting with the aim of preventing dental erosion.

Objective: Purpose of this research was to examine the onset, progression and wear rates of dental erosion in an established mouse model. Material and methods: Dental erosion in mice was experimentally induced, and the acidic effects of cola drink on their teeth after 2, 4 and 6-weeks were closely analysed by scanning electron microscopy. The tooth height and enamel or dentin loss were established. Results: The dental erosion on the molars showed clear progression from 2 to 6 weeks. By the 2-week mark, a significant portion of enamel was already eroded, revealing the dentin on the lingual cusps. When adjusted for attritional wear, molars exposed to cola for 2 weeks showed a 35% drop in lingual tooth height compared to controls (533 μm vs. 818 μm). At 4 and 6 weeks, the cola-exposed group continued to display decreased lingual tooth heights by 40% (476 μm vs. 799 μm) and 43% (440 μm vs. 767 μm), respectively. Conclusion: This study revealed significant acidic effects of cola drink on mouse molars as early as 2 weeks. These findings highlight the challenge of monitoring dental erosion clinically and underscore the importance of early preventive and intervention measures.

Objective: This study aimed to quantitatively investigate the accumulation of Streptococcus mutans biofilm on enamel and root surfaces and assess the amount of biofilm removal using (1) experimental toothpaste and (2) water, in a closed system of flow chamber. Methods: Eight sound premolars were embedded in epoxy resin and polished with silicon carbide grinding papers to display enamel and root surfaces. To mimic biofilm, cultures of Streptococcus mutans were prepared and grown on the tooth surfaces over night before they were exposed to either 2 liters of Milli Q water or 2 liters of 40% experimental toothpaste in the flow chamber. The amount of biofilm was measured and quantified in Fluorescence microscopy. Mean fluorescence values were recorded and analysed using Microsoft® Excel® (MS Excel 2016). Results: The ability to grow biofilm was equally present at both the enamel and root surfaces. The use of water and 40% experimental toothpaste showed a significant reduction of areas covered with biofilm on both enamel and root dentin in comparison to untreated surfaces (p < 0.01). Significantly more biofilm was removed from enamel compared to root surfaces when treated with either water and toothpaste (p < 0.01). Slightly less biofilm was removed by the use of water compared to toothpaste on both enamel and root dentin surfaces, although the differences were not statistically significant. Conclusion: The results indicate that less biofilm is removed from the root surfaces than enamel by the use of water and 40% experimental toothpaste in flow chamber. Assessing oral biofilm accumulation and monitoring biofilm formation on enamel and root dentin surfaces give oral health professionals important directions that could strenghten the significance of dental caries prevention. Improving older individuals’ oral hygiene practices should therefore be considered an important measure to prevent root caries.

AbstractObjective To compare the cumulative impact of sequential wear on mechanical properties and appearance of a composite resin (CR), Filtek Z250®, a glass ionomer GI, Fuji IX GP®, and a glass hybrid (GH), Equia Forte®.Material and Methods Six equally sized specimens of each material were subjected to wear tests, i.e., simulation of brushing, chewing and acidic liquid exposure, mimicking at least 6 months of clinical exposure. Surface roughness, hardness, substance loss and degree of shade lightness were determined.Results Following wear tests, significant increase in surface roughness and decrease in hardness values were observed for all materials (p < .05). Significantly larger substance loss was found in Equia Forte® specimens compared to Filtek Z250® (p < .05), while that of Fuji IX® exceeded the measurement capacity of the instrument. Opposite to the two other materials, the shade of Filtek Z250® became darker.Conclusions Sequential wear exposure mimicking abrasion, erosion and attrition to products representing CR, GI and GH, caused weakening and change in appearance of the materials. The composite resin was the most mechanically resistant to the sequential wear.

The ionospheric refraction of GNSS signals can have an impact on positioning accuracy, especially in cases of single-frequency observations. Ionosphere models that are broadcasted by the satellite systems (e.g., Klobuchar, NeQuick-G) do not include enough details to permit them to correct single-frequency observations with sufficient accuracy. To address this issue, regional ionosphere models (RIMs) have been developed in several countries in the western Balkans based on dense Continuous Operating Reference Stations (CORS) observations. Subsequently, a RIM for the western Balkans was built using an artificial neural network that combined regional ionosphere parameters estimated from the CORS data with spatiotemporal (latitude, longitude, hour of day), solar (F10.7) and geomagnetic (Kp, Dst) parameters. The RIMs were tested at the solar maximum (March 2014), a geomagnetic storm (March 2015), and the solar minimum (March 2018). The new RIMs mimic the integrated electron density much more effectively than the Klobuchar model. Furthermore, RIMs significantly reduce the ionospheric effects on single-frequency positioning, indicating their necessity for use in positioning applications.

Introduction and case report: We described a case of primary spontaneous partial pneumothorax in a middle-aged man with COVID-19 pneumonia who presented with fever, loss of appetite, and malaise. Laboratory results revealed higher levels of inflammatory markers, as well as sterile urine and blood cultures. On admission, a chest X-ray revealed bilateral patchy consolidations in the lung parenchyma, as well as a left-sided partial pneumothorax. Throughout his hospitalization, the patient was closely examined by a thoracic surgeon, and a chest X-ray was taken on multiple occasions. There was spontaneous resorption of air from the pleural space. Conclusion: Pneumothorax is a rare but serious complication of the COVID-19 infection that has recently been documented in patients with no comorbidities, requiring various types of ventilatory support. The precise mechanism of primary spontaneous pneumothorax in COVID-19 infection is unknown, but it will undoubtedly pose a challenge to future researchers.

Introduction: Erosive tooth wear (ETW) is a multifactorial condition of increasing prevalence in the younger population. This study aimed to explore the association between different ETW phenotypes with MMP2 and COMT single-nucleotide variants and selected environmental factors. Methods: Saliva samples, erosive wear, and dental caries experience data and dietary/behavioral information from 16- to 18-year-old patients (n = 747) were used. Genotypes were obtained, and phenotypes were further analyzed considering diet and behavioral data, using logistic regression as implemented in PLINK, with an alpha of 0.05. Results: When comparing individuals' ETW-free with those with mild ETW, an association was found with COMT rs6269 (p = 0.02). The comparison between ETW-free individuals with individuals with severe ETW also showed an association with COMT rs6269 under the recessive model (p = 0.03). Logistic regression showed that in the presence of less common alleles of MMP2 rs9923304 and COMT rs6269, ETW was more likely to occur when individuals drank wine. The GG genotype of COMT rs6269 was associated with the presence of lower (p = 0.02) and higher (p = 0.02) caries experience when individuals with ETW only in enamel were compared with individuals with ETW involving dentin. Conclusion: The results support a role of genes in ETW, with wine consumption being identified as a significant modulator, suggesting that gene-environment interactions may contribute to the development of ETW.

Abstract Early identification of high-risk pregnancies enables identification of those who would benefit from aspirin prophylaxis and increased surveillance for pre-eclampsia. A high body mass index (BMI) is a well-known predictor for pre-eclampsia. However, if abdominal adipose tissue distribution is associated with pre-eclampsia is limited investigated. Subcutaneous adipose tissue (SAT) thickness and visceral adipose tissue (VAT) thickness were measured by ultrasound on 3777 women at around 18 gestational weeks. SAT thickness was measured from the skin to linea alba and VAT from linea alba to the anterior aortic wall. The risk of developing pre-eclampsia (de novo hypertension at ≥ 20 gestational weeks in combination with proteinuria) was evaluated by logistic regression and expressed as odds ratio (OR) with 95% confidence intervals (CI). The risk of pre-eclampsia increased by 79% for every cm in SAT thickness (OR 1.79; 95% CI 1.48–2.17) and by 23% for every cm VAT thickness (OR 1.23; 95% CI 1.11–1.35). After adjustment for maternal age, parity, BMI, smoking and country of birth, the association between SAT thickness and pre-eclampsia remained (AOR 1.35; 95% CI 1.02–1.79). Greater SAT thickness measured with second trimester ultrasound is associated with increased risk of developing pre-eclampsia. The measurement may improve prediction models for pre-eclampsia.

\nIntroduction: The aim of this cross-sectional study was to explore the degree whereby dentists differentiate between repair versus replacement for failed restorations. A random selection of adult patients from North Norway was chosen from the larger Tromsø 7 study. Methods: A randomized sample of 3,653 persons (11.5% of the total number of individuals invited to the Tromsø 7 study, 51.5% women, aged 40–93 years) were included. Based on FDI’s clinical criteria for the evaluation of restorations – 2010, 17 calibrated dentists evaluated patients by clinical and radiographical pictures in a specially designed software developed for this purpose. The dental practitioners’ opinions gave rise to the reported treatment decisions. Descriptive statistics and multivariable multilevel mixed-effect logistic regression models (STATA 17/SE) were performed. Results: The participants’ DMFT values ranged from 0 (0.9%) to 24 (8.8%) (median DMFT 21.3, mean 20.0). A total of 90.062 teeth (24.7 teeth per patient) were assessed. Re-treatment suggestions were made for 3,006 restorations, i.e., an average of 3.3% re-treatments. Of these, 25.3% (n = 814) were suggested for repair and 74.7% (n = 2,192) for replacement. Dental treatment was suggested for 1,597 patients and varying from 1 to 14 suggestions per patient. Secondary caries (37.6%) and restoration fracture (15.2%) were found to be most frequently used indications for re-treatment, surface properties the least. No significant difference was found between assessing dentists based on sex or age. Clustering by dentist level was checked using intra-class correlation coefficients, demonstrating that 16% of the variance in suggestions for restoration re-treatment was explained at the dentist level. Thus, a wide range of treatment suggestions was noted among the dentists. Conclusion: Need for restoration revision seems low in North Norway. There is a tendency towards larger and more indirect restorations, and the diagnosis of secondary caries is still a matter of uncertainty. A randomized population of adults over 40 years, selected among the citizens of Tromsø County in North Norway, were examined by dentists, resulting in a study group of 3,653. Clinical examinations were executed, clinical photos and X-rays taken of each patient in a dental clinic. This is part of the Tromsø 7 study. A specially designed data programme was developed, and 17 trained dentists were able to assess the clinical state of restorations. All the dentists were working as clinical teachers in dental schools. The purpose was to decide what kind of treatment they thought best for unacceptable restorations. Should they be replaced or repaired if revision was needed. Only 3.3% of all examined teeth were proposed for restoration revision, which seemed to be rather low. Among the suggested revisions, approx. 25% were recommended for repair, while 75% was assigned for replacement. Tooth-coloured material, i.e., composite, was recommended in almost 75% of the cases. Different kinds of crowns counted for 25%. A considerable difference in the number of treatment suggestions was noted among the dentists. Statistical analyses demonstrated that 16% of the difference in suggestions for restoration re-treatment depended on different dentist opinions. Secondary caries and restoration fracture were found to be the most used indications for re-treatment. Need for restoration revision seems low in North Norway. However, there is a tendency towards larger and more indirect restorations. The diagnosis of secondary caries is still a matter of uncertainty. [ABSTRACT FROM AUTHOR]

Abstract Background Stainless-steel crowns (SSCs) are recommended for restorative treatment of young teeth severely affected by caries, fractures or dental developmental disorders (DDDs). However, despite recommendations and clinical evidence, SSCs are not widely used by general dentists, who favour extraction and more conventional restorations. The present study aimed to investigate the views of and use of SSCs among Norwegian and Finnish dentists. Methods The present study was a cross-sectional survey among Norwegian and Finnish dentists. An electronic questionnaire was sent to Norwegian and Finnish dentists asking whether they used SSCs and on which indications. In addition, the questionnaire assessed reasons for non-use and dentists’ perceptions regarding advantages and challenges in the use of SSCs, as well as the need for additional training. Distributions of background characteristics, use of and views on SSCs were calculated, and statistical significance of the associations between respondents’ background and their answers were evaluated. Results Of the 574 Norwegian and 765 Finnish respondents, only 12.0% and 12.9% reported to use SSCs, respectively. The most frequently reported barrier reported by those who did not use SSCs was lack of practical training. The most frequent challenge reported by those using SSCs was difficulties in crown adjustment followed by aesthetic issues, and the most frequently reported advantage was that SSCs maintain the function and occlusion. The majority of respondents reported a need for more information and practical training in the use of SSCs, with hands-on course as their most frequently preferred education type. Conclusion Although the value of SSCs for restoring young molars is recognized by Norwegian and Finnish dentists, SSCs are rarely used by general dentists. The majority of the respondents reported lack of training and materials and was interested in receiving more information and education.

Abstract Objective To examine the knowledge and experience of erosive tooth wear (ETW) among Danish dental practitioners and, based on two cases, explore their treatment decisions. Methods We sent a validated questionnaire electronically to all active members of The Danish Dental Association and The Association of Public Health Dentists in Denmark. The questionnaire had two parts; the first focused on scoring, recordkeeping, knowledge and experience of ETW. The second part presented two patients with different severity of erosive lesions to explore the dentists preventive and restorative treatment decisions. Results We received 442 answers from 4,490 potentially eligible dentists in Denmark (response rate 9.8%). The majority (78%) was female and the median age was 44 years. Nearly all respondents (97%) registered ETW in the charts and 49% recorded “always” or “often” the patients' diet history, most commonly with aid of interviews. The respondents perceived the prevalence of ETW to be higher today than 10–15 years ago and male patients (15–25 years) appeared more affected than females. The majority (82%) thought that they usually found the probable cause of the condition with carbonated beverages being the most common factor. The treatment included dietary guidance, soft tooth brushing with non‐abrasive fluoride toothpaste, topical fluoride applications and direct composite restorations. Conclusion The majority of Danish dentists taking part of this survey had adopted a minimally invasive approach for the management of erosive tooth wear in young adults. There was however room for improvements in diagnosis, scoring and case documentation.

Abstract This study investigated whether maternal central adiposity and body mass index (BMI) were associated with neonatal hypoglycemia and adverse neonatal outcomes. A cohort study was performed at Uppsala University Hospital, Sweden, between 2015 and 2018. Visceral and subcutaneous fat depths were measured by ultrasound at the early second-trimester anomaly scan in 2771 women giving birth to singleton infants. Body mass index was assessed in early pregnancy. Logistic regression models were performed. Adjustments were made for age, BMI (not in model with BMI as exposure), smoking, maternal country of birth, and parity. Outcomes were neonatal hypoglycemia (blood glucose concentration

Public procurement is investigated in terms of results and maximum efficiency of allocation of financial resources of the national public budget. In the context of economic development, optimization of the management of public financial resources is based on improving the legislation on public procurement and the financing mechanism. Based on this, public procurement is a complex, multi-level, interdependent system, the functioning at the all public levels. The aim of the research is to conduct a comprehensive study of the main problems and features of public procurement financing in order to optimize public finance management at the national level and to develop recommendations for improving the public procurement system in the Republic of Moldova. The methodology is based on the structural research method. The article is based on a study of the public procurement system in the Republic of Moldova, analyzing its constituent elements. The analytical method was used to study the concept of public procurement. The study established the relationship between the ethical behavior of officials, the effectiveness of control and the implementation of information systems to optimize the system of financing public procurement in the Republic of Moldova. Proposals are presented to improve the efficiency of the public financing mechanism in the context of electronic public procurement procedures within the automated information system “State Register of Public Procurements” MTender

Introduction: It is generally accepted that physical activity benefits every person but athletes diagnosed with asthma face various challenges during their training to keep the symptoms of the disease under control. Prolonged exposure to agents in the environment in which athletes train favors the development of permanent changes in the airways. Their action leads to permanent hyper reactivity with development of an inflammatory response and the release of mediators (IL-8, leucotriens, eicosanoids) that lead to damage epithelial cells with breaking connection between them and consequent dysfunction of the respiratory system. This condition is called exercise-induced asthma (EIA). This fact is especially important for athletes who have long endurance training. The best way to check the condition of breathing system is with a diagnostic method which is the „ gold“ standard- spirometry. Aim: The point of this systematic review is to get closer the mechanism occurrence of EIA/(exercise induced bronchoconstriction)-EIB, prevalence and incidence of EIA/EIB, changes of pulmonary function and quality of life in elite athletes. We searched papers from PubMed and Cochrane database using keywords: 'exercise-induced asthma', 'athletes', ' spirometry', 'bronchoconstriction', ’bronchospasm’, 'physical activity', 'physical training', 'prevalence', 'incidence'. We have studied 48 scientific papers in total. Conclusion: The prevalence of asthma among elite athletes, especially endurance athletes is higher than in general population. The explanation of this phenomenon is related to the whole mechanism of occurrence, it is still insufficiently clarified, but one thing is for sure that with good disease control athletes can play and compete undisturbed for many years.

Objective: To determine if protein profiles identified in saliva could be used to determine risk and severity of erosive tooth wear. Material and Methods: Three types of saliva sampling were performed to obtain saliva from 34 18-year old individuals that received regular dental check-ups, along with clinical status of the dentition and risk factor related to erosive tooth wear using the VEDE scale. Protein profiles in saliva were determined using electrophoresis and the calculation of the percentage of a specific band at a specific molecular weight in relationship to the total protein in that sample (% of total) using molecular weight standards. This quantification was repeated for each protein band across a range of molecular weights for each sample to test for association with erosive tooth wear status. Results: There were no differences in the number of detectable proteins sourced from the parotid gland, nor the unstimulated and stimulated whole saliva. Five out of the 34 individuals had no signs of erosive tooth wear despite an acidic diet and were more likely to have proteins with molecular weight smaller than 1 KDa (p=0.03). Conclusion: There is potential for the use of protein profiling to determine risks for erosive tooth wear.

BackgroundOur aim was to investigate the relationship between caries experience and erosive tooth wear in adolescents.MethodsWe compared the Decayed, Missing, and Filled Teeth (dmft/DMFT) data of 795 adolescents to their erosive tooth wear scores using diet as a covariate and determined whether dental caries and erosive tooth wear scores are associated with each other, using linear regression analysis. Diet data and oral hygiene habits were collected using self-reported surveys and erosive tooth wear scores were previously collected. We also compared patients' genotypes and phenotypes and looked for an association between erosive tooth wear experience and different single nucleotide polymorphisms (SNPs). A Bonferroni correction was implemented to correct multiple comparisons. Two-group comparisons were made depending on the phenotype definitions implemented, and both chi-square and linear regression analyses were used to the test association between genetic variants and caries definitions. All covariates were included in each model.ResultsFor four SNPs (rs17159702, rs10246939, rs1800972, and rs1676303), there was an association between a spike in caries experience of DMFT 4 or more between two time points and increased frequency of fruit juice intake. A fifth SNP rs2860216 was shown to be a protective factor against a caries spike when associated with more frequent yogurt consumption. We did not find significant associations between our dental caries phenotypes or our demographic data and erosive tooth wear status in our linear regression.ConclusionsDental caries and erosive tooth wear are two diseases that differ in mechanism and heritability.

COVID-19, caused health and economic problems in almost all countries. This crisis has caused unprecedented supply and demand shocks and led to significant changes in people’s behavior and spending. Demand depends on consumer behavior, which may have changed with the outbreak of the pandemic. Consumer Behavior is a process of analyzing the causes and patterns of consumer behavior when purchasing products and services. The article analyzes the changes in consumer behavior during the COVID-19 pandemic in the Western Balkans.

Introduction: The prevalence of idiopathic hypercalciuria (IH) in healthy pediatric population ranges from 3.0% to 7.0%. There is insufficient data about IH in children with mono-symptomatic enuresis. The aim of this study was to examine calcium excretion in urine (UCa) in patients with primary mono-symptomatic nocturnal enuresis (PMNE). Methods: In patients with PMNE, aged 5 to 17 years, IH was determined in 24-h urine and from second morning spot urine. The completeness of the 24-h urine collections was estimated via measuring 24h-urine creatinine excretion (UCr) of 0.1–0.2 mmol/kg/24h. Results: Sixty patients with PMNE, 32 males and 28 girls, median age of 9 years were enrolled in the study. Only 41.7% patients successfully completed 24 h urine collection. IH, defined as 24-h UCa >0.1 mmol/kg body weight, was diagnosed in 12% of the patients, while when defined as UCa/UCr >0.8 mmol/mmol in children 5-7 years and >0.6 mmol/mmol in those>7 years, IH was 8.3% and 6.7% from 24h- urine and spot urine, respectively. Conclusion: Children and adolescents with PMNE are in risk of hypercalciuria. Therefore, it is useful to examine 24 hours of urine calcium excretion in these patients.

Introduction: The concept of subclinical thyroid disease appeared in the 1980s when sensitive procedures for the measurement of the thyroid-stimulating hormone in the serum were introduced. Subclinical hypothyroidism is defined by the finding of elevated serum TSH concentrations with normal thyroid hormone levels. The incidence of subclinical hypothyroidism with increased cardiovascular risk has not yet been fully clarified. The aim of the study was to identify anthropometric parameters that may indicate an increased cardiometabolic risk in patients with subclinical hypothyroidism. Method: The study will include 140 patients aged 18-65, with 105 patients with subclinical hypothyroidism and a control group of 35 healthy, normally nourished subjects without subclinical hypothyroidism. A program of research will be carried out in all patients and it will include: detailed anamnesis and physical examination, anthropometric measurements (weight measurements, body height, waist circumference, hip circumference, body weight mass measurement by the bioelectrical impedance analysis method (%BFP), calculation of: body mass index (BMI), waist-to-hip circumference ratio (WC/HC), waist-to-height ratio (WC/Ht) and laboratory testing (FT3, FT4, TSH). Results: Examinees with subclinical hypothyroidism had statistically significantly elevated mean TSH values (6.87+1.34 mIU/ml) compared to TSH euthyroid examinees (1.9+.88 mIU/ml). The mean age of subjects with subclinical hypothyroidism was 44.15±11.23 years (MA = 43 years), and in subjects without subclinical hypothyroidism, 33.80±10.60 years (MA = 33 years). In relation to the control group (euthyroid patients), patients with subclinical form of hypothyroidism had higher average mean values and statistically significantly higher incidence of elevated values: BMI (T test=7.465, p

Objective Charcoal-containing dentifrices are gaining popularity, but scientific information on their effect on oral health is scarce. This study investigated properties of dentifrices that may affect dentine abrasivity, as well as their ability to adsorb fluoride, their pH and the presence of harmful substances. Materials and methods The dentifrices NAO and COCO were subjected to the following analyses: abrasivity, expressed as mean abraded depth and relative dentin abrasivity (RDA), and surface roughness of extracted human molars (n = 30) after simulated brushing; fluoride adsorption measured as concentration change; pH measurements; detection of polycyclic aromatic hydrocarbons by gas chromatography–mass spectrometry. The products were compared to a reference dentifrice (Colgate® MaxWhite), positive controls (ISO dentifrice slurry, activated charcoal for laboratory use) and a negative control (distilled water). Results The mean abraded depths of NAO and COCO were not different (p > .05), but higher than the reference dentifrice and the negative control (p .05). Both NAO and COCO were alkaline (pH > 7). Analysis of NAO revealed the presence of naphthalene (112.8 ± 2.0 ng/mL). Conclusion The charcoal-containing dentifrices were abrasive within acceptable limits set by ISO and did not adsorb fluoride. The presence of naphthalene in one product is a cause for concern.

Introduction: Arteriovenous malformations of the brain include a group of congenital disorders in the early development of arterial-venous blood vessels of the brain. Their clinical presentation is most common in the form of a brain hemorrhage, epileptic seizures, and headaches. Case report: We showed a man who at the age of 28 early in the morning after breakfast had the first generalized tonic-clonic seizure. After the second unprovoked epileptic seizure, antiepileptic therapy was introduced. The brain scanner showed the existence of arteriovenous malformations in the right frontoparietal region. As the size of the malformation was less than 30mm, it was decided that the patient should be treated with Gamma knife radiosurgery. After the successful radiosurgery together with the antiepileptic drugs treatment, the patient is in a stable 1.5 year- long remission of epileptic seizures without neurological failures. Conclusion: Epileptic seizures can be the initial clinical manifestations of arteriovenous malformations of the brain. With an early diagnosis, adequate antiepileptic drugs therapy and neurosurgery, radiosurgery (Gamma Knife), which is often necessary, many symptomatic epilepsies enter a stable remission of epileptic seizures.

Abstract Background Current knowledge on treatment strategies and choice of restorative materials when treating deep caries or severe dental developmental defects (DDDs) in young individuals is scarce. Therefore, the aim was to investigate Norwegian dentists´ treatment decisions and reasons for treatment choice when treating deep caries in primary teeth and severe DDDs in permanent teeth in children. Methods A pre-coded questionnaire was sent electronically to all dentists employed in the Public Dental Service (PDS) in Norway (n = 1294). The clinicians were asked about their background characteristics and how often they registered DDDs. Three clinical cases were presented to the dentists and asked to prioritize treatment options and reasons for their choice. Results After three reminders, 45.8% of the dentists answered. Most clinicians were general practitioners (96.3%), females (77.9%), under 41 year-olds (59.4%), graduated in 2001 or later (61.1%), and representing all regions of Norway. The respondents registered molar incisor hypomineralisation (MIH), other DDDs and dental fluorosis (DF) frequently, 523 (91.1%), 257 (44.8%) and 158 (27.5%), respectively. In case 1a with severe dental caries in a primary molar, the preferred treatment was resin-modified glass ionomer cement (RMGIC) (58.3%), followed by glass ionomer cement (GIC) (17.9%) and zinc oxide-eugenol (ZOE) (13.2%). Extraction, compomer or stainless steel crowns (SSC) were preferred by 0.9, 0.7 and 0.4%, respectively. In case 1b, which was identical to case 1a, but treated under general anaesthesia, the preferred treatment alternatives were RMGIC (37.1%), resin composite (RC) (17.6%) and GIC (17.2%). Extraction and SSC were chosen by 15.1 and 7.2%, respectively. In case 2, showing a severely hypomineralised and symptomatic first permanent molar, the dentists preferred RC (38.4%), followed by RMGIC (26.6%) and GIC (19.0%). Extraction and SSC were chosen by 8.7 and 5.4%, respectively. The treatment choices were not significantly affected by the dentists’ background characteristics. The reasons for dentists’ treatment decisions varied for each patient case; patient cooperation, prognosis of the tooth and own experience were the dominant reasons. Conclusions A notable disparity in treatment choices was shown indicating that Norwegian dentists evaluate each case individually and base their decisions on what they consider best for the individual patient.

Pulmonary embolism (PE) and deep vein thrombosis (DVT) are associated with considerable morbidity and mortality, and for as much as twenty-five percent of PE patients the primary clinical appearance is unexpected death. Diagnosis of PE is based on clinical suspicious at first, but sometimes its diagnostics can be extremely difficult. Newly increased interest in an inherited thrombophilic states has been provoked by the discovery of several common inherited abnormalities, i.e. the prothrombin (PT) gene G20210A, Factor V Leiden (FVL) mutation (Arg506Gln), hyperhomocystenemia and homocysteiuria, Wein-Penzing defect, Sticky Platelet Syndrome (SPS), Quebec platelet disorder (QPD) and Sickle Cell Disease (SCD). PE incidence rates increase in recent years. The only explanation at this moment is increased awareness of PE, especially after any kind of surgery, immobile state or unexplained shorthness of breath.

Objectives. Xerostomia is a subjective sensation of dry mouth. It is commonly associated with salivary gland hypofunction. Both changes in the composition of the saliva and a reduction in the quantity secreted may be an objective finding of dry mouth. Although there are no currently available cures for the conditions resulting in dry mouth, there are several treatment options that give hope for patients who suffer from xerostomia. Individuals with some residual salivary gland function, which are contraindicated to pharmacological therapies, would benefit the most from identifying novel, alternative effective methods for stimulating production of saliva. The aim of this study was to give an overview of the latest and most relevant data related to treatment modalities for the management of dry mouth conditions. Data Resources and Study Selection. The present review was prepared by searching the National Library of Medicine database using the relevant medical terms and their combinations. A total of thirty-three studies met the inclusion criteria. Data were extracted by one author and verified by another. Conclusion. A number of patients showed positive treatment outcomes, and the adverse effects of both electrical stimulation (ES) and acupuncture have been reported as mild and transient. In patients who have undergone radiotherapy, acupuncture is shown to increase salivation. However, in patients with Sjogren’s syndrome, the effects of ES devices seem to be elusive. Moreover, due to the instability of the findings in relation to longevity of clinical effect, patient satisfaction, quality of life, and clinical effectiveness of such treatments, the results remain vague.
