Objective: To analyze multiple‐causal models, including socioeconomic, obesity, sugar consumption, alcohol smoking, caries, and periodontitis variables in pregnant women with early sugar exposure, obesity, and the Chronic Oral Disease Burden in their offspring around the first 1000 days of life. Methods: The BRISA cohort study, Brazil, had two assessments: at the 22nd–25th gestational weeks and during the child's second year (n = 1141). We proposed a theoretical model exploring the association between socioeconomic and pregnancy factors (age, smoking, alcohol, sugars, obesity, periodontitis, and caries) and child's variables (sugars and overweight) with the outcome, Chronic Oral Disease Burden (latent variable deduced from visible plaque, gingivitis, and tooth decay), using structural equation modeling. Results: Caries and periodontitis were correlated in pregnant women. Addictive behaviors in the gestational period were correlated. Obesity (Standardized coefficient ‐ SC = 0.081; p = 0.047) and added sugar consumption (SC = 0.142; p = 0.041) were observed intergenerationally in the pregnant woman‐child dyads. Sugar consumption by the children (SC = 0.210; p = 0.041) increased the Chronic Oral Disease Burden. Conclusions: Poor caries and periodontal indicators were correlated in pregnant women and their offspring. Obesity and sugar consumption act intergenerationally. Oral health in early life may change life trajectory since the worst oral conditions predict main NCDs. [ABSTRACT FROM AUTHOR]

Objective: To determine the frequency of oral squamous cell carcinoma (OSCC) associated or not with oral potentially malignant disorders (OPMD), and the epidemiological profile and traditional risk factors in Latin America. Methods: A retrospective observational study was conducted in 17 Latin American centres. There were included cases of OSCC, analysing age, gender, OSCC and their association with previous OPMD. Clinicopathological variables were retrieved. The condition of sequential‐OSCC versus OSCC‐de novo (OSCC‐dn) was analysed concerning the aforementioned variables. Quantitative variables were analysed using Student's t‐test, and qualitative variables with chi‐square. Results: In total, 2705 OSCC were included with a mean age of 62.8 years old. 55.8% were men. 53.75% of the patients were smokers and 38% were common drinkers. The lateral tongue border was the most affected site (24.65%). There were regional variations in OPMD, being leukoplakia the most frequent. Of the overall 2705 OSCC cases, 81.4% corresponded to OSCC‐dn, while s‐OSCC were 18.6%. Regarding lip vermillion SCC, 35.7% corresponded to de novo lip SCC and 64.3% were associated with previous OPMD. Conclusions: In Latin America, OSCC‐dn seems to be more frequent with regional variations of some clinical and histopathological features. Further prospective studies are needed to analyse this phenomenon. [ABSTRACT FROM AUTHOR]

Currently, approximately 70% of new cases of Chagas disease (CD) in Brazil are attributed to oral transmission, particularly through foods such as açaí, bacaba, and sugarcane juice, primarily in the northern and northeastern regions of the country. This underscores the imperative need to control the spread of the disease. The methods utilized to conduct quality control for food associated with outbreaks and to assess the potential for the oral transmission of CD through consuming açaí primarily rely on isolating the parasite or inoculating food into experimental animals, restricting the analyses to major research centers. While there are existing studies in the literature on the detection and quantification of T. cruzi DNA in açaí, the evaluation of parasites' viability using molecular methods in this type of sample and differentiating between live and dead parasites in açaí pulp remain challenging. Consequently, we developed a molecular methodology based on RT-qPCR for detecting and quantifying viable T. cruzi in açaí pulp samples. This protocol enables the stabilization and preservation of nucleic acids in açaí, along with incorporating an exogenous internal amplification control. The standardization of the RNA extraction method involved a simple and reproducible approach, coupled with a one-step RT-qPCR assay. The assay underwent validation with various T. cruzi DTUs and demonstrated sensitivity in detecting up to 0.1 viable parasite equivalents/mL in açaí samples. Furthermore, we investigated the effectiveness of a bleaching method in eliminating viable parasites in açaí samples contaminated with T. cruzi by comparing the detection of DNA versus RNA. Finally, we validated this methodology using açaí pulp samples positive for T. cruzi DNA, which were collected in a municipality with a history of oral CD outbreaks (Coari-AM). This validation involved comparing the detection and quantification of total versus viable T. cruzi. Collectively, our findings demonstrate the feasibility of this methodology in detecting viable forms of T. cruzi in açaí pulp samples, emerging as a crucial tool for monitoring oral outbreaks of Chagas disease resulting from açaí consumption.

Objective: To evaluate the impact of the COVID‐19 pandemic on the number of diagnoses of oral and maxillofacial lesions in public laboratories after one year of COVID‐19 outbreak in Brazil. Material and Methods: This is a cross‐sectional study. Biopsies submitted to histopathologic examination from March 2019 to February 2020 (pre‐pandemic period) and from April 2020 to March 2021 (pandemic period) in nine Brazilian public oral pathology laboratories were retrieved and the number of diagnoses, types of lesion, and percentage changes during both periods were analyzed. Results: There were 7389 diagnoses in the pre‐pandemic period and 2728 in the pandemic era, indicating a reduction of 63.08%. The reduction was 64.23% for benign lesions and 49.48% for malignant lesions, with a 50.64% reduction in squamous cell carcinoma. The largest decreases were observed in April 2020 and January 2021. Conclusion: An important reduction in the diagnoses of benign and malignant lesions was noted in the Brazilian public oral pathology laboratories during the first year of the COVID‐19 pandemic.

Objective: To evaluate the prevalence of oral mucosal lesions (OML) and oral self‐examination and their associated factors among pregnant women from the 2015 Pelotas Birth Cohort Study, Brazil. Methods: Pregnant women who would deliver babies in 2015 were included in the antenatal study. Data related to demographic, socio‐economic and behavioural conditions were collected using questionnaires. Participants were also clinically assessed for oral health outcomes. The outcomes were the presence of OMLs and oral self‐examination. Size, location, time of onset and symptomatology of the lesions were collected. Descriptive and bivariate analysis, and Poisson regression were performed. p‐Value <0.05 was set to indicate statistical significance. Results: Data from 2481 pregnant women were analysed. Four hundred and nine (16.5%) had at least one OML. The most prevalent lesions were exostosis (80/16.6%), coated tongue (70/14.5%) and benign oral brownish pigmentation (68/14.1%). Non‐white skin colour was associated with a higher prevalence of OMLs (PR 1.3; 95% CI 1.1–1.6), while daily use of dental floss was positively associated with the prevalence of oral self‐examination (PR 1.4; 95% CI 1.2; 1.5). Conclusions: Almost 20% of pregnant women presented OML, which were more prevalent in non‐white individuals. Women with better oral care were more likely to perform oral self‐examination.

Objective: The aim of this study was to evaluate the bibliometric profile of dental scientific production related to coronavirus disease-2019 (COVID-19) in Scopus (2019–2020). Materials and Methods: This was a descriptive, observational, comparative, and retrospective study. All manuscripts on COVID-19 in dentistry were published between December 2019 and December 2020. The variables were measured objectively through Scopus (SciVal). For the extraction of the manuscripts, the following keywords were used: "Covid-19" and "Dentistry" with its multiple MeSH terms using the Boolean operators "OR" and "AND". On June 14, 2021, 843 manuscripts corresponding to the period January 2019 to December 2020 were downloaded, normalized, and refined through metadata analysis. Results: The largest number of manuscripts was published in the International Journal of Current Research and Review, Oral Oncology, Oral Diseases, British Dental Journal, and Journal of Dental Education with 54, 50, 49, 48, and 44 manuscripts, respectively. These are the most productive indexed scientific journals on COVID-19. The most productive institutions were Saveetha University, Universidade de São Paulo, and King's College London, with 42, 33, and 27 manuscripts, respectively. In 2019, there were only two scientific publications on COVID-19. In 2020, the largest amount, 228 manuscripts, were published in Q1 journals, followed by 210 manuscripts in Q3 journals, and only 194 manuscripts were published in Q4 journals. Conclusions: Currently, there is a notable increase in global academic production in Scopus on the impact of COVID-19 in dentistry, whereas Brazil is the only South American country with three highly productive universities.

Background: Dental caries is associated with Biological, behavioral, socioeconomic, and environmental factors; however, socioeconomic status is a distal determinant of dental caries development that modulates exposure to risk and protective factors. This study aimed to analyze the socioeconomic factors associated with the concentration of oral diseases in a population-based study in Brazil. Methods: This is a quantitative, analytical, cross-sectional study based on secondary data from the SB São Paulo 2015 epidemiological survey. A total of 17,560 subjects were included. The concentration of oral disease in the population was estimated by the oral disease burden (ODB) variable. The ODB consists of four components: dental caries; tooth loss; need for dental prosthesis and periodontal condition. Thus, the total score on the ODB could vary between 0 and 4, with the highest score indicating the worst possible situation. ODB was analyzed in multivariate negative binomial regression, and multivariate binary logistic regression analysis. The following factors were included as independent variables: age group, skin color, socioeconomic factors, family income and Oral Impact on Daily Performance (OIDP). Results: In the sample, 86.9% had no minimum ODP component. Negative multivariate binomial regression showed a statistically significant relationship (p < 0.005) between ODB and all variables analyzed (skin color, family income, education, OIDP results and age range). The adjusted multivariate binary logistic regression showed that the individuals most likely to have at least one component of ODB were nonwhite (25.5%), had a family income of up to R$ 1500.00/month (19.6%), had only completed primary education (19.1%), and reported that their oral health had an impact on their daily activities (57.6%). Older adults individuals were two times more likely than adolescents to have an ODB component. Conclusions: ODB is associated with factors related to social inequality. Adults and older adults individuals had the highest cumulative number of ODB components. [ABSTRACT FROM AUTHOR]

Sex workers, including female ones, have a higher risk of developing cancer and oral diseases due to the overlapping of risk factors. To characterize oral health status and healthcare practices and behaviors in female sex workers. Both quantitative and qualitative concomitant approaches were used. A closed-ended questionnaire, clinical examination, and semi-structured interview were administered, from July 2017 to August 2018, to 21 intentionally selected participants, in the city of Itajaí, southern Brazil. Although the participants reported having good oral health and healthcare habits, some oral diseases and harmful habits were observed. Poor oral hygiene and habits such as smoking, alcohol, and illicit drug use were found. Most of the participants had undergone gynecological follow-up in the last 12 months. Qualitative analysis gave rise to six categories: Social aspects of working as a sex worker, Work routine, Sexual practices and behaviors and protection from sexually transmitted infections, Practices and behaviors (including unprotected sun exposure, smoking, and alcohol use at work), Use of illicit drugs at work, and General and oral health care and perceptions about their oral health. Oral health status of the participants was variable, and most of them smoked cigarettes, drank alcohol, and consumed illicit drugs at work. Preventive condom use was reported. Most of them underwent recent serological tests for sexual diseases and gynecological follow-up, incentivized by the community health workers that facilitate access to public services.

Background: Syphilis is an infectious, sexually transmitted disease with varied oral manifestations, that can mimic other lesions. This study aimed to conduct an epidemiological survey of cases of syphilis, diagnosed from oral manifestations, establishing the sociodemographic profile of patients and clinical characteristics of oral lesions. Methods: The medical records of patients with oral lesions of syphilis acquired were reviewed, and 109 cases were selected. Results: The mean age of the patients was 34.4 years and, of these, 51% were male. In 105 cases, the disease was diagnosed in the secondary stage; in three cases, in the primary stage; and, in one case, in the tertiary stage. The cases of primary syphilis presented as single and ulcerated nodules, and the case of tertiary syphilis, as a necrotic lesion in the palate. In 86% of cases of secondary syphilis, there were multicentric lesions, presenting as grayish‐white plaques (85%), associated or not with erosive and/or ulcerated lesions (33%), mostly affecting the labial mucosa and tongue. In 91.7% of cases painful symptoms were reported. Conclusion: Considering the increase in syphilis, it is extremely important that dentists recognize its oral manifestations, because early diagnosis and treatment can minimize the risks of complications and transmission.

Background: We performed a systematic review of studies conducted in Latin America and the Caribbean (LAC) to assess the impact of oral diseases on oral health-related quality of life (OHRQoL). Materials and methods: Searches were performed of the following PubMed, EMBASE, CINAHL, Scopus, and LILACS databases. Randomized clinical trials, quasi-experimental studies, cohort studies, case and control studies, and cross-sectional studies which included at least 100 participants evaluating the impact of oral diseases on OHRQoL were included. PROSPERO registry number: CRD42020156098. Results: After exclusion of duplicates, 3310 articles were identified, 40 of which were included in this review. 90% of the studies were conducted in Brazil. The most commonly used OHRQoL measuring instruments were CPQ 11–14 (n = 9), ECOHIS (n-8) and B-ECOHIS (n = 8). The study designs included 32 cross-sectional, 2 cohort and 6 case and control studies. Most of the studies were conducted in children (n = 25) and adolescents (n = 9). Most studies identified an impact on OHRQoL in children, adolescents and adults with oral diseases. Moreover, greater oral disease severity had a greater impact on OHRQoL. Conclusions: Most studies in LAC report a negative impact of diseases on OHRQoL. More longitudinal studies are required to confirm the results of these studies. [ABSTRACT FROM AUTHOR]

Purpose: This study described and compared the oral characteristics of Brazilian individuals with mucopolysaccharidosis (MPS) and without MPS. Methods: A cross-sectional study was performed with 29 individuals with MPS and 29 without MPS and their parents/guardians. The individuals were aged between 3 and 21 years and attended at two hospitals in Belo Horizonte, southeastern Brazil. The dental characteristics were evaluated by clinical examination of dental caries, gingivitis, malocclusion, dental anomalies and developmental defects of enamel. The parents/guardians answered a questionnaire about the sociodemographic and behavioural aspects of their children. The study was approved by the Research Ethics Committee of the Federal University of Minas Gerais. Results: The average age of the individuals was 13.9 years (± 7.2). The majority were male (58.6%), had black/brown skin (70.7%) and were from favored economic class (89.7%). Dental caries, gingivitis, malocclusion and dental anomalies were more prevalent in the MPS group (p < 0.05). Conclusion: The individuals with MPS had a higher prevalence of oral diseases and dental anomalies than the group without MPS. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the effect of the COVID-19 impacts on the activities of researchers in the field of Oral Medicine (OM) and Oral Pathology (OP). To assess the research activities and training of human resources by Brazilian productivity fellows in research (BPFR) in OM and OP in the COVID-19 Era. Material and Methods: Thirty-six BPFR in OM and OP areas, funded by National Council for Scientific and Technological Development (CNPq), received a virtual structured questionnaire by e-mail, on the Google Forms (Google®) platform, with questions regarding research activities and training of human resources (supervision of undergraduate and postgraduate students), during the COVID-19 pandemic. From the thirty-six BPFR in OM and OP, twenty-seven (75.0%) answered the questionnaire. Results: Most of them were males (n=20; 74.1%) and were distributed in four Brazilian regions and ten states of the federation, including the Federal District. Twenty-four (88.9%) BPFR reported having suspended clinical activities, while sixteen (59.3%) answered that histopathology practices are suspended. Twenty-five (92.6%) BPFR mentioned difficulties in conducting research projects and 55.5% stated having no difficulties in the supervision of undergraduates, master's and PhD students. Conclusion: The current scenario may significantly impact the diagnosis of oral diseases in Brazil. Moreover, a decrease in the scientific production of BPFR in OM and OP in the coming years is also considered. [ABSTRACT FROM AUTHOR]

Dental features have been considered a potential target of verbal bullying (VB) among school-aged children. The authors conducted a study to investigate the association between the presence of oral disorders and the occurrence of VB among 8- through 10-year-old school-aged children. The study included 445 school-aged children 8 through 10 years old. VB was verified by a specific validated question from the Child Perceptions Questionnaire 8-10 index. Oral disorders such as untreated caries, fluorosis, clinical consequences of untreated caries, and malocclusion were evaluated. The Pearson χ2 test and bivariate and multivariate conditional logistic regression analyses were used for statistical analysis. A total of 390 school-aged children completed the study. The results of the multivariate logistic regression model showed that a severe malocclusion (odds ratio [OR], 2.29; 95% confidence interval [CI], 1.03 to 5.10), a greater maxillary misalignment (OR, 2.23; 95% CI, 1.05 to 4.73), and the presence of a tooth with pulp exposure (OR, 2.93; 95% CI, 1.58 to 5.45) were significantly associated with the occurrence of VB. Children aged 8 through 10 years with a severe malocclusion, larger maxillary misalignment, or the presence of pulp exposure had increased odds of experiencing VB compared with children without those oral health conditions. Once oral disorders involved in VB are identified, appropriate approaches should be used to address this issue. With this course of action, oral health care professionals may use the treatment and preventive care to eliminate potential factors for peer aggression. [ABSTRACT FROM AUTHOR]

Objective: To identify the oral lesions of individuals with kidney disease immediately before and shortly after kidney transplantation, taking into account the immunosuppressive regimen, antiviral prophylaxis and type of transplantation.Methods: A prospective observational cohort study was carried from January 2017 to January 2018. Eighty individuals aged 18 years or older who were admitted for kidney transplantation were eligible to participate. Clinical data regarding medical history, immunosuppressive therapy, antiviral prophylaxis, laboratorial data and oral examination were performed by the same trained researcher, in three different moments: 24 hours before transplantation (1st time point), 15-20 days (2nd time point) and 45-60 days (3rd time point) after transplantation.Results: In the first, second and third time points, it was found that 3.7% (3/80), 23.7% (18/76) and 25.7% (19/74) of the participants showed oral soft tissue lesions. Ulcers and candidiasis were the most frequent oral lesions, and they were associated with the use of everolimus (p = .005) and azathioprine (p = .034), respectively. Less patients reported xerostomia after transplantation than before (p < .001).Conclusions: Oral lesions are common in the short term after renal transplantation and are particularly related to both toxicities of immunosuppressive drugs and immunosuppression.

Prevention and health promotion are considered important strategies to control oral diseases. Dental caries is preventable disease and remains the most common chronic disease that affects mainly low income children and still considered the main cause of tooth loss in adulthood in Brazil. The aim of this study is to present a System Dynamics model (SDM) specifically developed with the Stella Architect software to estimate the cost and clinical hours required to control the evolution of dental caries in preschool children in Maringá, Brazil. Two main strategies to control caries were considered in the model: the application of fluoride varnish on teeth presenting white spots, and the use of Atraumatic Restorative Treatment (ART) in cavitated carious lesions without pulp involvement. The parameters used in the model were: number of people covered by a local oral health team = 4,000; number of children up to 5 years = 7% of the population; children's decayed, missing, filled teeth (dmft) index = 2.4; time/cost of 4 applications of fluoride varnish = 5 minutes/US$ 0.716; and time/cost of each ART restoration = 15 minutes/US$ 1.475. The SDM generated an estimated total cost of US$698.00, and a total of 112 clinical hours to treat the population in question. The use of the SDM presented here has the potential to assist decision making by measuring the material and human resources required to prevent and control dental caries at an early age.

Purpose: The aim of this study was to assess the impact of clinical oral health conditions, and the prevalence, intensity and the impact of dental pain on daily living among 5-year-old preschool children.Materials and Methods: A cross-sectional survey was carried out on a sample of 578 children attending preschools in Belo Horizonte, Brazil. Data were collected by means of a pretested questionnaire given to the parents and a visual analogue scale of faces applied to the children. The children underwent dental examinations.Results: According to the parents' reports, the lifetime prevalence of dental pain was 25.0% (95% confidence interval, 95% CI = 21.4 to 28.6), and dental pain caused crying in 16.8% (95% CI = 13.6 to 19.9) of the children; 10.7% (95% CI = 8.1 to 13.3) of children had dental pain in the 2 months prior to the dental examination. Among this group of children with dental pain, 59.3% experienced a negative impact as a result of pain. The following clinical conditions had mostly caused dental pain in the 2 months prior to the dental examination: root remnants, fistula and pulp caries. This recent pain resulted in a visit to the clinician in 13.6% of the children.Conclusions: Prevalence, intensity and the impact of dental pain in 5-year-old children were high in Belo Horizonte, Brazil. Dental pain assessed in the present study was associated with avoidable pathological factors. However, only few children were treated professionally for the dental pain they were experiencing. Public policies should be developed and implemented to promote fair, comprehensive treatment for the population. [ABSTRACT FROM AUTHOR]

Aims: To assess the effects of oral pain on oral health-related quality of life during pregnancy and document measures taken by pregnant women seeking relief for oral pain. Their experience of other types of pain were also investigated. Methods: A sample of pregnant women who were admitted to a public hospital to give birth were invited to participate in this cross-sectional study. Those who agreed were asked if they had experienced any pain due to problems with their mouth, teeth, or dentures during the 6 months prior to the interviews. Interviewees who answered affirmatively were questioned about the effects of this pain on their normal activities with the Oral Impacts on Daily Performances (OIDP) tool. Results: The study population consisted of 504 subjects (83% of the eligible individuals). A high prevalence of untreated dental caries was found. The prevalences of oral pain, headaches, back pain, and pelvic pain were 39.1%, 61.5%, 59.3%, and 60.9%, respectively. Of those reporting pain, 168 (33.3%) reported having had difficulty doing at least one of the activities included in the OIDP due to oral pain. The most frequently mentioned effects were difficulty in maintaining emotional balance (23.6%), difficulty eating (22.8%), and difficulty cleaning teeth (20%). The mean and median OIDP scores were 13.9% and 8.0%, respectively. Conclusion: Oral pain during pregnancy was an important problem for this group of women and had a negative effect on their quality of life. [ABSTRACT FROM AUTHOR]

Introduction: Oral diseases are frequent in dentistry. It is important to know the clinical and epidemiological characteristics of a series of cases of white lesions to intercept possible cancerous lesions of the oral cavity, enabling proper diagnosis and correct treatment. Aim: The objective of this study was go through the profile of a series of patients with white oral lesions treated at the Faculty of Dentistry of the University of Passo Fundo, RS, Brazil, in a 2-year period. Materials and Methods: The records of patients treated between July 2017 and June 2019 were analysed. In a total of 3,000 patients were initially analysed, 1,829 (60.96%) were women and 1,171 (39.04%) were men. The epidemiological data of the individuals (geographic region of origin, age, gender, ethnicity and deleterious habits) were collected, as well as clinical data regarding lesions {clinical or histopatologic diagnosis (depending on the lesion), aetiology, surface keratinization, treatment performed and time of evolution}. Data collected were entered into Microsoft Excel spread sheet and analysed using SPSS version 23.0 software. Chi-square test was used to compare categorical variables at 95% significance level. Results: It was observed that white lesions were more prevalent in males (25-69.4%), who were in the sixth decade of life (17- 47.2%), white people (31-86.1%), that inhabited the southwest Rio-Grandense (35-97.2). As for lesions, actinic chelitis (8-22.2%), with "excessive sun exposure" (8-22.2%) and non scrapable surface (24-66.7%) were the most frequent lesions. No cases of leukoplakia were identified. The most common form of treatment for the lesions was laser therapy (7-19.4%) and the evolution time was up to three months (24-66.7%). The majority of the patients (19-52.8%) were neither smoker nor alcoholic (27-75.0%). Conclusion: Actinic cheilitis was the most prevalent lesion. The cancerous lesions included in the sample (lichen planus, nicotine stomatitis, frictional keratosis and actinic cheilitis) demonstrate a significant presence in the sixth decade of life and men had more deleterious habits when compared to women in the studied region.

Objective: This study aims to describe the primary care services carried out by Oral Health Teams (OHTs) in Brazil, and to understand the nuances that lead to different levels of OHT performance. Material & methods: A mixed-methods study with a sequential explanatory design was developed. In the quantitative phase, secondary data from a national survey (PMAQ-AB) was used to describe the work of 12,403 OHTs. Item response theory (IRT) was applied, to evaluate the psychometric qualities of 20 oral health questions from PMAQ-AB and to identify the performance of OHT. The quantitative results guided the selection of the qualitative sample. An extreme case sampling strategy was used (opposite results). OHTs were selected from Belo Horizonte metropolitan region in Brazil using scores measured by IRT. Data were collected through semi-structured interviews. Data analysis was conducted using deductive and inductive thematic analysis. Results: Quantitative results showed that there are OHT with high and low performance in Brazil. The IRT analysis showed that items related to prostheses and oral cancer tend to discriminate high-performance OHTs from other OHTs. Qualitative results deepened the understanding of accessing oral health services and found several access barriers, such as the insufficient number of OHTs for the population, and a very long waiting time for dental consultations other than urgency. The qualitative results confirmed that high-performance OHTs tend to emphasize oral cancer surveillance and deliver prostheses in PHC services. Conclusion: Despite the expansion of oral health in PHC in Brazil in recent years, OHTs still face many challenges such as: access barriers; failures in prevention, early diagnosis and follow-up of oral cancer cases; and insufficient rehabilitation with prostheses.

The purpose of this article is to carry out a literature review on oral health team in primary care with their inclusion in the Family Health Strategy (FHS). The publications were consulted in national papers, official documents and other publications of Health Ministry (MS). In the literature it is observed that with the creation of the Unified Health System (SUS) a process of health restructuring services in Brazil began. The Primary Care National Policy (PNAB) is the result of several historical facts involved with the development and consolidation of SUS. The Family Health Program (PSF), now called the Family Health Strategy (ESF) was created in 1994 aimed at reorienting health care with new bases, centering family focus and attempting to achieve improvement in quality of life of Brazilians. In 2000, oral health teams were included in the PSF to extend access of the Brazilian population to health promotion actions, prevention and recovery of oral health, improve health indicators and encourage the reorganization of dentistry in primary care. ESF is a unique strategy in the reorganization of the Brazilian health system and the inclusion of the ESB an important complement in primary care, aiming an integral dental practice.

The objective of the present study was to analyze individual, contextual and social support factors associated with periodontal condition among 2332 dentate elderly Brazilian participants from the São Paulo State Oral Health Survey 2015 (SBSP-15). Methods: This study used the database compiled by the SBSP-15, conducted from January to December in 2015. The associations were made by relative risk (RR), with Multilevel Poisson Regressions, among individual, contextual and social support variables, and had periodontal diseases as outcomes. Results: The mean age of elders was 70.13 years (SD 5.67). The risk factors for all outcomes of periodontal diseases were male gender and self-perceived color of non-white skin. Regarding social support, feeling unhappy was a risk factor for the presence of shallow periodontal pockets (3–5mm) RR 1.43(CI 95% 1.10–1.86). The coverage of the Family Health Strategy (FHS) was a protective factor for gingival bleeding RR = 0.7(CI 95% 0.44–0.99) and calculus RR = 0.75(CI 95% 0.60–0.95), and a risk factor for the number of lost sextants (sextants with only one tooth or without any teeth) RR = 1.12(CI 95% 1.00–1.28). Living in municipalities with more than 90% fluoridation coverage was a protective factor for the number of lost sextants RR = 0.89(CI 95% 0.78–0.99). Conclusions: The study showed evidence that individual (gender and self-perceived skin color), contextual (coverage of the family health strategy and water fluoridation) and social support factors (feeling unhappy) are associated with the clinical outcomes of periodontal diseases in Brazilian elders. This reinforces the need for transdisciplinary actions in the FHS, stimulating work together and intersectoral collaboration between FHS and NASF (Family Health Support Center).

Objectives: To investigate the frequency of oral paracoccidioidomycosis from representative geographical regions of Brazil and to compare the data with a literature review. Materials and methods: A retrospective study was conducted on 108,304 biopsies obtained from 1953 to 2016 at six Brazilian oral and maxillofacial pathology services. Demographic data and clinical and histopathological diagnosis of oral paracoccidioidomycosis were evaluated. A literature review of oral paracoccidioidomycosis studies published in three electronic databases was carried out. Data were analysed descriptively. Results: A total of 320 cases of oral paracoccidioidomycosis were surveyed (0.3% of the oral lesions at the centres studied). The lesions were more frequent among male patients. The gingiva/alveolar ridge was the most affected site. Mean age of affected individuals was 51.3 years (±11.7). The literature review showed a higher incidence of oral paracoccidioidomycosis in the south‐east and south regions of Brazil. Male individuals and individuals between 50 and 59 years were most affected. Conclusions: Oral paracoccidioidomycosis is an uncommon lesion observed in oral biopsy samples. The differences in the relative frequency of oral paracoccidioidomycosis are related to geographical variations. Men between 50 and 59 years are more affected. This study provides helpful information for clinicians in the diagnosis of oral paracoccidioidomycosis. [ABSTRACT FROM AUTHOR]

This study evaluated oral hygiene habits and their association with sociocultural, environmental factors and factors related to the use of dental services among Quilombola and non-Quilombola rural adolescents from inland Bahia. Thiswas a cross-sectional study conducted in 2015. Prevalence and prevalence ratios were estimated for the outcomes and multiple Poisson regression analysis with robust variance was performed. We interviewed 390 adolescents, of which 42.8% were Quilombola. Poor tooth brushing and non-flossing were found in 33.3% and 46.7% of adolescents, respectively. Poor tooth brushing was increased by male gender (PR = 1.45), not living with both parents (PR = 1.45), lower hand hygiene habit (PR = 1.72) and worse oral health self-assessment (PR = 1.38). Non-flossing was associated with economic level E (PR = 1.54), older age (PR = 0.91), lower hand hygiene habit (PR = 1.53) and worse oral health self-assessment (PR = 1.33). Different associated factors were observed between Quilombola and non-Quilombola. It is necessary to consider the specificities of the populations for the promotion of adolescent oral health and the importance of the intersectoriality between education and health and care to families.

Abstract: Objectives: To determine whether subjective oral symptoms were associated with self‐rated oral health after controlling for sociodemographic characteristics and dentition status in 4 different Indigenous peoples from Central‐West Brazil. Methods: A population‐based cross‐sectional study of oral health was conducted between 2012 and 2014. The randomly selected sample was stratified according to 4 ethnic groups (Kaiwoá, Kadiwéu, Terena and Guarani) and 2 age groups (15‐19 and 35‐44 years). The outcome was poor self‐rated oral health. Independent variables obtained by interviews were age, sex, ethnicity, schooling, family income, self‐reported toothache, difficulty chewing and difficulty speaking due to dental problems. Dentition status, oral morbidity and normative treatment needs were obtained through oral examinations. Unadjusted and adjusted prevalence ratios (PR) and respective 95% confidence intervals (CI) were estimated using Poisson regression modelling with robust variance estimation. Results: Poor self‐rated oral health was more common in the older age group and in Guarani peoples than their counterparts (PR = 1.06 [1.00‐1.12]; PR = 1.09 [1.02‐1.16], respectively). After adjusting for sociodemographic characteristics, fewer functional teeth (PR = 1.11 [1.02‐1.20]), 2 or more untreated decayed teeth (PR = 1.15 [1.07‐1.23]), normative need for extraction (PR = 1.15 [1.05‐1.25]) and normative need for restoration of one or more surfaces (PR = 1.16 [1.05‐1.27]) were positively associated with self‐rated oral health. Toothache and difficulty speaking remained positively associated with the outcome after controlling for all previous variables (PR = 1.10 [1.05‐1.18]; PR = 1.20 [1.09‐1.32]). Conclusions: Oral symptoms such as toothache and difficulty speaking due to dental problems play an important role in oral health self‐rating. Self‐rated oral health is an appropriate indicator for use in diverse sociocultural contexts. [ABSTRACT FROM AUTHOR]

Chronic oral diseases are rarely studied together, especially with an emphasis on their common risk factors. This study examined the association of added sugar consumption on "chronic oral disease burden" among adolescents, with consideration of obesity and systemic inflammation pathways through structural equation modeling. A cross-sectional study was conducted of a complex random sample of adolescent students enrolled at public schools in São Luís, Brazil ( n = 405). The outcome was chronic oral disease burden, a latent variable based on the presence of probing depth ≥4 mm, bleeding on probing, caries, and clinical consequences of untreated caries. The following hypotheses were tested: 1) caries and periodontal diseases among adolescents are correlated with each other; 2) added sugar consumption and obesity are associated with chronic oral disease burden; and 3) chronic oral disease burden is linked to systemic inflammation. Models were adjusted for socioeconomic status, added sugar consumption, oral hygiene behaviors, obesity, and serum levels of interleukin 6 (IL-6). All estimators of the latent variable chronic oral disease burden involved factor loadings ≥0.5 and P values <0.001, indicating good fit. Added sugar consumption (standardized coefficient [SC] = 0.212, P = 0.005), high IL-6 levels (SC = 0.130, P = 0.036), and low socioeconomic status (SC = -0.279, P = 0.001) were associated with increased chronic oral disease burden values. Obesity was associated with high IL-6 levels (SC = 0.232, P = 0.001). Visible plaque index was correlated with chronic oral disease burden (SC = 0.381, P < 0.001). Our finding that caries and periodontal diseases are associated with each other and with added sugar consumption, obesity, and systemic inflammation reinforces the guidance of the World Health Organization that any approach intended to prevent noncommunicable diseases should be directed toward common risk factors.

Objective: The aim of this study was to evaluate the association between sense of coherence and oral health among older adults treated at family health units in southern Brazil.Material and Methods: The sample was composed of 164 individuals aged 60 years old or older. Socio-demographic and oral health variables were collected using a standardised questionnaire. Sense of coherence (SOC) was measured with the questionnaire proposed by Antonovsky containing 29 closed-ended questions. Poisson regression analysis was employed to identify factors associated with SOC.Results: Among the 164 older adults, 53.9% were edentate, 54.5% did not need any type of dental prosthesis, and 82.1% had good/adequate self-assessed oral health. The multivariate analysis revealed lower SOC scores among non-white individuals [Mean Ratio (MR)=0.94; 95% CI: 0.91-0.97; P<.001], with poor/very poor self-assessed oral health (MR=0.85; 95% CI: 0.78-0.91; P<.001) and with one or more teeth present in the oral cavity (MR=0.94; 95% CI: 0.91-0.97; P<.001).Conclusion: The present results show that older adults who are self-reported as non-white, with one or more teeth in the oral cavity and with poor/very poor self-assessed oral health have lower SOC scores.

Background: To investigate the association between critical and communicative oral health literacy (OHL) and oral health outcomes (status, oral health-related quality of life and practices) in adults.Methods: This cross-sectional study examined a household probability sample of 248 adults, representing 149,635 residents (20-64 years old) in Piracicaba-SP, Brazil. Clinical oral health and socioeconomic and demographic data, as well as data on oral health-related quality of life (OHIP-14) and health practices were collected. The oral examinations were carried out in the participants' homes, using the World Health Organization criteria for oral diseases. The critical and communicative OHL instrument was the primary independent variable, and it was measured using five Likert items that were dichotomized as 'high' ('agree' and 'strongly agree' responses for the 5 items) and 'low' OHL. Binary and multinomial logistic regressions were performed on each outcome (oral health status and practices), controlling for age, sex and socioeconomic status (SES).Results: Approximately 71.5% presented low OHL. When adjusted for age and sex (first model) low OHL was associated with untreated caries (Odds Ratio = 1.92, 95% Confidence Interval = 1.07-3.45), tooth brushing <3 times a day (OR = 2.00, 1.11-3.62) and irregular tooth flossing (OR = 2.17, 1.24-3.80). After SES inclusion in the first model, significant associations were found for low OHL when the outcomes were: presence of biofilm (OR = 1.83, 1.08-3.33), dental care for emergency only (OR = 2.24, 1.24-4.04) and prevalence of oral health impact on quality of life (OR = 2.06, 1.15-3.69).Conclusion: Adjusting for age, sex and SES, OHL is related to a risk factor (biofilm) and a consequence of poor oral health (emergency dental visits) and can interfere with the impact of oral diseases on quality of life. As low OHL can be modified, the results support oral health promotion strategies directed at improving critical and communicative oral health literacy in adult populations. [ABSTRACT FROM AUTHOR]

Objectives The aim of this study was to investigate the prevalence of oral and maxillofacial lesions among older adults (≥60 years) from representative regions in Brazil. Design Retrospective descriptive cross-sectional study. Setting Biopsy records were obtained from the archives of four Brazilian referral centers of oral diagnosis between 2000 and 2016. Participants A total of 45,506 biopsy records of all patients were analyzed, of these 7,259 persons aged 60 and older were selected. Measurements Data such as gender, age, race, anatomical location, and histopathological diagnosis were collected and categorized. Pearson's chi-square test ( P < .005) was used to evaluate differences in the frequency of the several groups of oral lesions. Results Oral and maxillofacial lesions were diagnosed in 7,259 older people, including 59.4% women ( P < .001) and 61.3% white patients ( P = .07). The most commonly affected sites were the cheek mucosa (20.3%) and mandible (8.9%) ( P < .001). Reactive and inflammatory lesions were the most common lesions, followed by neoplasms. Oral squamous cell carcinoma was the most prevalent neoplasm (83.4%) ( P < .001). Conclusion Knowledge of oral diseases obtained from biopsy records provides more accurate data about the diagnosis and oral health of elderly patients. These indicators thus support the development of specific health policies for the prevention and treatment of oral and maxillofacial lesions that affect this population. [ABSTRACT FROM AUTHOR]

Background: Denture-related erythematous stomatitis (DES) is a chronic biofilm-mediated disease, affecting one in every three complete denture wearers. Antifungals are the treatment most commonly prescribed by oral health professionals, based on the belief that colonization by Candida spp. is the main cause of DES. However, high recurrence rates and adverse effects are commonly observed, prompting the need for practice guidelines regarding treatment. Results from our pilot study demonstrate that palatal brushing can reduce the palatal inflammation and potentially associated Candida carriage without any need for antifungal therapy. The objective of this study is to validate these pilot results by means of a randomized controlled trial (RCT) and provide a practice guideline for clinicians.Methods/design: A pragmatic, two-parallel-arm, multicenter RCT will be conducted in Canada, Brazil, and Chile. Fifty-two adult complete denture wearers presenting with moderate to severe DES will be allocated randomly to two groups: the Intervention arm will consist of palatal brushing and standard oral and denture hygiene measures, while the Control arm will include only standard oral and denture hygiene measures. The study outcome will be the oral Candida carriage. Participants will be assessed at baseline, and at 3 and 6 months post intervention. Descriptive, bivariate, and mixed models with repeated measures will be performed following the intention-to-treat principle.Discussion: This pragmatic RCT will serve to provide a clinical practice guideline regarding the use of preventive measures in the treatment of biofilm-mediated oral diseases. Moreover, it will have a great impact on reducing the harm of antifungal overtreatment on patients suffering from DES.Trial Registration: ClinicalTrials.gov, NCT02686632 .

Background: Oral complications may be observed during chemotherapy and are important side effects that may directly affect the anticancer treatment, even causing septicaemia in some cases. This research was done in order to evaluate changes in oral lesions during follow-up of children and adolescents in chemotherapy at Hospital Estadual Infantil Nossa Senhora da Glória (HEINSG). Methods: The study design was longitudinal, 45 patients were evaluated and monitored for 1 month after the initiation of chemotherapy. Twenty-eight patients were male and 17 female, ranging from 3 months to 18 years old. Results: The results show an increase in the number of mucositis cases and a decrease in xerostomia cases after the initiation of treatment, and other oral lesions were also found in low numbers. Conclusions: It is possible to avoid oral complications by maintaining a good oral health, and reducing infectious outbreaks. It is also feasible to obtain an early diagnosis of, and treat these oral complications, preventing them from following a more severe clinical course that may negatively affect the individual's treatment. This outcome requires the presence of a dental surgeon on the multidisciplinary cancer treatment team. [ABSTRACT FROM AUTHOR]

The article offers information on the oral cancer diagnosis during the Covid-19 pandemic in an oral pathology laboratory in Rio de Janeiro, Brazil. It mentions the lack of consensus about the most effective biosafety practices, pathologists and laboratory technicians have been trying to adopt measures to minimize the possibility of Covid-19 spreading inside the pathology laboratory, particularly while handling specimens from the oral cavity.

Aims: To evaluate the perception of parents about the impact of oral problems in their children, and of demographic, socioeconomic and psychosocial factors on the oral health-related quality of life (OHRQoL) of Brazilian adolescents and young adults with intellectual disability (ID), in 2014.Methods: The sample consisted of 119 individuals. Data collection was performed in stages: calibration and pilot study; Application of questionnaires; Exam of caries, periodontal and need for dental prostheses, in accordance with the World Health Organization criteria. The data were subjected to both bivariate and multivariate analyses to test the association of independent variables with the dependent variable (QoL).Results: Worse QoL was associated with the presence of periodontal pocket (p = 0.03; OR = 2.50; 95% CI 1.06 to 5.90), treatment need (p = 0.01; OR = 5.00; 95% CI 1.37 to 18.31), and need for dental prostheses (p = 0.03; OR = 2.89; 95% CI 1.13 to 7.37).Conclusion: It was concluded that clinical determinants had the greatest influence on OHRQoL of individuals with ID.

Aim To assess differences in the oral diseases/conditions between adults and older adults. Methods A cross-sectional study was carried out with all adults and older adults in Luzerna, South Brazil ( n = 569). Clinical data included use of and need for dental prostheses; number of decayed, missing and filled teeth; and temporomandibular disorder. Differences between adults and older adults were evaluated using χ2-tests. Associations between independent variables and the use of and need for dental prostheses were determined using Poisson regression analyses ( P < 0.05). Results Increased number of decayed, missing and filled teeth, use of and need for dental prostheses, higher use of complete dentures, and fewer temporomandibular disorder signs and symptoms were observed in older adults. After adjustments, lower social class ( P = 0.001) and unmarried status ( P = 0.05) were associated with greater need for prosthetic rehabilitation. Women ( P = 0.02), older individuals ( P < 0.001) and those of lower socioeconomic status ( P = 0.001) had a higher risk of using prostheses. Conclusion A significant difference of oral conditions between adults and older adults was observed. The frequency of use of and need for dental prostheses was higher for older adults, although they had reported lower frequency of temporomandibular disorder. Women, married and individuals of higher socioeconomic status showed better oral health conditions. Geriatr Gerontol Int 2016; 16: 1014-1020. [ABSTRACT FROM AUTHOR]

Objectives To determine the prevalence of oral potentially malignant disorders (OPMDs) in a population of rural workers in the northeast of Brazil and to investigate the association with sociodemographic, occupational, and health factors. Methods A total of 1385 workers answered a validated questionnaire and were examined by calibrated dentists. A descriptive analysis, chi-square homogeneity test, and binary logistic regression were performed. Results The prevalence of OPMDs was 29.6%. Actinic cheilitis was the most predominant (28.4%), followed by leukoplakia (2.3%) and erythroplakia (0.3%). Gender, type of skin, and time exposed to the sun explained the presence of OPMD ( P < 0.0001). The study found increased prevalence, especially for males over the age of 60 years and being exposed to the sun for more than 45 years. Conclusion Rural workers showed high vulnerability to the presence of OPMDs, as estimated prevalence exhibited was high. [ABSTRACT FROM AUTHOR]

Aim To evaluate the effect of oral disorders on the quality of life of older adults. Methods A cross-sectional study of older adults (aged ≥60 years) who reside in a small Brazilian city was carried out. Trained and calibrated academics and dentists collected the data. The analyses carried out were descriptive, univariate and multiple through logistic regression using pasw Statistics 18.0 software. Results A total of 351 older adults were included in the study. The majority of older adults did not express impacts as a result of oral disorders. The physical domain of quality of life was compromises more in older adults who had physical incapacities related to oral health (odds ratio 3.62, 95% confidence interval 1.34-9.73). Conclusion In general, among the older adults evaluated, it was found that both the overall score and the individual scores for the four domains of quality of life were influenced by one of the seven domains of the impacts of oral disorders.

Purpose: This study investigated the relationship between contextual and individual social determinants of oral health-related quality of life (OHRQoL) in Brazilian adults.Methods: Data of 4594 Brazilian adults aged 35-44 years from the 2010 Brazilian Oral Health Survey were analysed. OHRQoL was measured using the Oral Impacts on Daily Performance (OIDP). Contextual socio-economic characteristics at city level assessed in 1991 and 2000 included social deprivation measured by Human Development Index (HDI) and income inequality (Gini index). Individual socio-economic characteristics included family income, schooling and number of goods. Covariates were age, sex, ethnicity and clinical oral measures. Multilevel multivariable Poisson regression analysis was carried to investigate the association of contextual and individual social characteristics with OIDP extent and with each OIDP item.Results: Eating and cleaning teeth were the most reported daily activities influenced by oral conditions. In the adjusted analysis, low HDI 1991 and individual social characteristics (lower family income and lower schooling) were associated with OIDP extent. Sex (females) and all clinical oral measures were also associated with OIDP. Adults living in the cities with low HDI 1991 were more likely to have impact on eating and sleeping, whereas living in cities with high Gini index 1991 increased the prevalence of impact on emotional status, work and social contact. Low income was associated with all OIDP items.Conclusion: Poor contextual social determinants and lower individual socio-economic position are associated with worse OHRQoL among Brazilian adults, even after adjusting for individual socio-demographic and clinical oral health variables.

Propolis is a complex resinous mixture collected by bees, with high medicinal, historical and economic value. The nutraceutical and pharmacological benefits of propolis have been extensively explored in several fields of medicine as an important resource for prevention and treatment of oral and systemic diseases. A relatively new type of propolis, named red propolis (in Brazil, Brazilian Red Propolis - BRP), has been arousing attention for the promising pharmacological properties of some of its isolated compounds (vestitol, neovestitol, quercetin, medicarpin, formononetin, etc). Due to a distinct chemical composition, BRP and its isolated compounds (mainly isoflavones) affect a wide range of biological targets and could have an impact against numerous diseases as an antimicrobial, anti-inflammatory and immunomodulatory, antioxidant and antiproliferative agent. In this review, we comprehensively address the main aspects related to BRP bioprospection, chemistry and therapeutic potential. Further information is provided on mechanisms of action discovered thus far as well as clinical use in humans and regulatory aspects. As of now, BRP and its isolated molecules remain a fascinating topic for further research and application in biomedical areas and dentistry. [ABSTRACT FROM AUTHOR]
