The prevalence of signs and symptoms of temporomandibular disorders (TMD) increases during adolescence and adulthood. Few studies have examined TMD prevalence in Brazilian adolescents.
To investigate ...the prevalence of TMD in Brazilian adolescents.
A representative population-based sample of 934 adolescents (10-14-years-old) was examined. TMD screening was performed using a questionnaire by the American Academy of Orofacial Pain. TMD diagnoses used research diagnostic criteria for temporomandibular disorders (RDC/TMD-Axis-I). Examinations were performed by a single calibrated examiner (kappa > 0.80).
The prevalence of TMD symptoms was 34.9%; the most frequently reported symptoms were headache and neck ache (20.9%), followed by joint sounds (18.5%). Myofascial pain was the most prevalent type (10.3%), followed by disc displacement with reduction (8.0%) and arthralgia (3.5%). There was a significant association between sex and TMD symptoms; prevalence was significantly higher in girls (RP = 1.37; 95% CI = 1.14-1.65; p = 0.001). Myofascial pain of TMD and displacement with reduction were more prevalent in girls (RP = 1.76; p = 0.007 and RP = 2.06; p = 0.004, respectively).
TMD symptoms were present in 34.9% of adolescents, with myofascial pain being the most prevalent type (10.3%). TMD was significantly more common in girls. Routine pediatric dental care should include a TMD screening.

Summary
Background
Temporomandibular Disorders (TMD) is a multifactorial condition, which could be associated to occlusal and psychological factors, such as anxiety.
Objective
Investigate if anxiety ...and malocclusion are associated with the prevalence of TMD in adolescents.
Methods
To ensure a population‐based representative sample, 934 adolescents aged 10 to 14 years old from Curitiba‐PR, Brazil were randomly selected and examined according to Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) and malocclusion by a single‐calibrated examiner (Kappa > 0.80). Anxiety was assessed according to trait anxiety (STAI‐T), categorised as high, moderate and low levels. For occlusal exam, it was considered: Angel's molar relationship, anterior and posterior crossbite, excessive overjet, open and deep bite. The associations were analysed by the crude and adjusted prevalence ration (RPa) of TMJ, calculated by a Poisson multivariate regression with robust variance (α = 0.05).
Results
The prevalence of at least one type of malocclusion was found in 52.3%. Anxiety was found in high level (12.2%), moderate (70.4%) and low (17.5%). Presence of high anxiety was significantly associated with the prevalence of TMD symptoms (RPa = 4.06, P < 0.001), as well as the prevalence of myofascial pain (RPa = 24.78; P < 0.001) and prevalence of disc displacement with reduction (RPa = 11.08, P < 0.001). Adolescents Class II had higher prevalence of myofascial pain (Class II RPa = 1.73; P < 0.015) than adolescents Class I. Adolescents Class III presented higher prevalence of myofascial pain (PRa 2.53; P = 0.004) than adolescents Class I.
Conclusion
Anxiety is strongly associated with TMD in adolescents. Presence of Class II or III is associated with higher prevalence of myofascial pain in adolescentsPLESAE check and approve the edit made in the article title.

The aim of this study was to evaluate whether genetic polymorphisms in AMELX, AMBN, ENAM, TFIP11, and TUFT1 genes are associated with dental fluorosis (DF). A total of 1,017 children from 2 Brazilian ...cohorts were evaluated. These populations lived in cities with fluoridation of public water supplies. DF was assessed in erupted permanent teeth using the modified Dean index. The polymorphisms rs946252, rs12640848, rs4694075, rs5997096, and rs4970957 were analyzed by real-time PCR from genomic DNA. Associations between DF, genotype, and allele distribution were evaluated using the χ 2 test, with an alpha of 5%. The polymorphisms rs4694075, rs5997096, and rs4970957 in AMBN, TFIP11, and TUFT1 were associated with DF (p < 0.05). In conclusion, enamel matrix genes are associated with DF.
Background
Few studies have evaluated the oral health status of children with a history of maltreatment.
Aim
This case–control study evaluated oral health in children who were victims of abuse and in ...child protective services in Curitiba, Brazil.
Design
One hundred twenty‐two children who were victims of abuse and 240 children with no history of abuse (mean ages, 8.56 and 8.24 years, respectively) were included in the study. Dental caries were assessed according to the Decayed, Missing, or Filled Teeth index (dmft index and DMFT index) by two calibrated examiners. The presence of anterior open bite and posterior crossbite was recorded. Data were analyzed using bivariate and adjusted odds ratios using a multivariate logistic regression model analyses.
Results
In the case group, we found a higher DMFT index (P < 0.001) and a significantly higher prevalence of missing primary teeth (P = 0.04), untreated decayed permanent teeth (P < 0.001), filled permanent teeth (P < 0.001), and anterior open bite (P = 0.04). Children who were victims of abuse presented an odds ratio of 6.48 (95% CI: 3.52–11.95) for caries in permanent teeth and an odds ratio of 2.28 (95% CI: 1.04–4.99) for open bite.
Conclusion
Victims of child abuse had a worse oral health status, demonstrating the need to establish special policies for oral healthcare for this population.

Abstract Objective: To translate and culturally adapt the Modified Child Dental Anxiety Scale - Faces (MCDASf) into Brazilian Portuguese. Material and Methods: The MCDASf consists of eight questions ...about anxiety toward dental procedures that are answered on a five-point Likert scale ranging from “not worried” (1 point) to “very worried” (5 points). The answers correspond to a scale of face drawings ranging from extremely negative to extremely positive. The process consisted of initial translation, back-translation, expert committee review, and pretesting. Results: The first revised version was applied to 32 children aged 5 to 12 years, 16 from the city of Governador Valadares, Brazil (southeastern region) and 16 from the city of Pelotas, Brazil (southern region). In the first pretest, Item 5 was misunderstood by 6.25% of children in the southern region; Item 6 by 6.25% in both regions; Items 7 and 8 by 87.5% and 100% of those from the southeastern region, respectively, and by 12.5% and 25% of those from the southern region, respectively. Items 7 and 8 were modified by the expert committee, and the second revised version was applied to 32 children, 16 from each region. The only misunderstood items were 4 and 5, both by a 7-year-old boy in Governador Valadares. Conclusion: The Brazilian Portuguese version of the MCDASf was well understood by the sample of children.
The epidemiological surveys aim to evaluate the distribution and state determinants or events in health in given populations. Objective: To conduct an epidemiological survey on the socioeconomic ...condition, use of dental services, referred oral morbidity, self-perception, and oral health of inhabitants of the Teixeira Island, Paraná, Brazil. Material and methods: The study followed the statements of the World Health Organization and the Brazilian National Epidemiological Survey (SB Brazil 2010). Questionnaires were applied, and in the clinical examination the following data were collected: dental trauma, edentulism, fluorosis, caries in deciduous teeth (dmft), caries in permanent teeth (DMFT), Community Periodontal Index (CPI) and Loss of Periodontal Insertion Index (LPII). The data were analyzed with Statistical Package for Social Sciences software, version 21.0, and expresses in frequency tables. Results: Of the 108 inhabitants, 90 participated in the study. The socioeconomics conditions unfavorable were: low income and low schooling. The water supplying was not fluoridated. The perception of oral problems was reported by 82.2%; 48.9% declared to have had toothache in last the six months; the reason of search for care was predominantly for curative treatments. Almost 30% of the participants declared to be unsatisfied with their oral health. The values of DMFT and dmtf indexes were 13.9 and 1.2, respectively. The greater demand for maxillary prosthesis occurred in 39.7% of the sample, while 34.2% needed mandibular prosthesis. Conclusion: The oral diseases illnesses and need of treatment were evidenced in the sample, as well as risk factors that deserve attention of the public power.
Tooth decay is still a highly prevalent disease in populations. Because of this, epidemiological studies are carried out frequently and allow the monitoring of the experience of the disease. ...Objective: To estimate the prevalence of dental caries of 5 and 12-years-old schoolchildren in the cities of Florianópolis, Santa Catarina, and Porto Velho, Rondônia, as well as to search hypotheses of association with social/economic determinants and access to dental services. Material and methods: Secondary data were used from the Brazilian Oral Health Survey of 2010, as follows: household income by city and dmft/DMFT index for ages by city and region of Brazil. Results: It was observed in the city of Florianópolis a 5-years-old dmft of 1.56, and 12-years-old DMFT of 0.55. In Porto Velho the means were 2.89 and 4.15 to the respective age. It was found that in Porto Velho 89.5% of surveyed had family income up to R$2,500.00, while in Florianópolis 81.9% had R$501.00 to R$9,500.00. Conclusion: The city of Florianópolis had the best caries indices and socioeconomic conditions, suggesting an association between these variables, in detriment to the regions in the opposite situation.
The child abuse against children and teenagers is relevant and the dentist has a fundamental role in the process of identification of suspected cases. Objective: To evaluate the level of knowledge of ...the dentists about child/teenager abuse and the attitude towards identified cases, in the cities of Rio Negro (Paraná, Brazil) and Mafra (Santa Catarina, Brazil). Material and methods: Questionnaires were applied to 44 professionals of these cities, who practiced in private and/or public health service. The questions covered the profile of respondents regarding gender, institution (public or private), level of education, practicing time and place. The information on abuse comprised the level of information about violence and knowledge on the compulsory notification of suspected cases. Results: Regarding the cases of abuse, 34% of the sample dealt with this situation. Almost half of respondents (47.7%) reported being able to recognize the typical lesions of child abuse, yet only 32% felt trained to do so. Only 22.7% reported having training to detect suspected cases. And 91% said they would notice the Guardian Council. About 48% confirmed they had knowledge of the legal implications in case of omission. Conclusion: Most of the dentists had insufficient knowledge about child abuse. However, the dentists know how to deal with such a situation. Continuing education seems to be an appropriate strategy to promote professional knowledge on the subject. It is also suggested the implementation of a national protocol to facilitate notifications and the classification of abuse types.
Oral diseases are among the problems that most affect the quality of life of people in the world. Traditional methods for drug treatment of these diseases are almost always expensive and, in ...addition, they cause side effects and can promote an increase in bacterial resistance. Thus, the demand for plant-derived products, such as herbal, floral and essential oils, has been growing every day, favoring the development of new therapeutic products that can replace or complement traditional therapeutic treatment. Among the natural products that have been gaining space, essential oils (EOs) stand out. Therefore, the aim of this study was to evaluate the role of thyme, oregano, copaiba, tea tree and frankincense EOs in inhibiting the growth of Enterococcus faecalis bacteria. The oil diffusion technique in agar was performed to evaluate the efficiency of the EOs, at different concentrations: 25%, 50%, 75% and 100%. The EOs that showed the greatest inhibition halo were, in decreasing order: Thyme Oil (5.0 mm), Tea tree Oil (4.70 mm) and Oregano Oil (3.75mm) in the concentration of 100%, with results similar to 0.12% chlorhexidine (positive control), whose inhibition halo was 3 mm. Copaiba and Frankincense oils were not efficient to inhibit bacterial growth at concentrations of 25, 50 and 75%. The results obtained in this research demonstrated that thyme, tea tree and oregano oils inhibited the growth of Enterococcus faecalis bacteria.
