The high cost of dental treatment can be avoided by effective preventive measures, which are dependent on dentists' adherence. This study aimed to evaluate the factors that drive dentists towards or away from dental caries preventive measures. Methods and Findings: This systematic review was registered in PROSPERO (CRD42012002235). Several databases as well as the reference lists and citations of the included publications were searched according to PRISMA guidelines, yielding 18,276 titles and abstracts, which were assessed to determine study eligibility. Seven qualitative studies and 41 surveys (36,501 participants) remained after data extraction and interpretation. A total of 43 findings were abstracted from the reports and were grouped together into 6 categories that were judged to be topically similar: education and training, personal beliefs, work conditions, remuneration, gender, place of residence and patients. The main findings for adherence based on their calculated frequency effect sizes (ES) were teamwork (21%) and post-graduation (12%), while for non-adherence were biologicism (27%), and remuneration for preventive procedures (25%). Intensity ES were also calculated and demonstrated low prevalence of the findings. Quality assessment of the studies demonstrated that the methodological quality, particularly of surveys, varied widely among studies. Conclusions: Despite the questionable quality of the included reports, the evidence that emerged seems to indicate that further education and training coupled with a fairer pay scheme would be a reasonable approach to change the balance in favor of the provision of dental caries preventive measures by dentists. The results of this review could be of value in the planning and decision making processes aimed at encouraging changes in professional dental practice that could result in the improvement of the oral health care provided to the population in general.

To minimize this problem, the monomeric composition of composites have been modified. The objective of this study was to conduct a meta-analysis to assess the clinical behavior of restorations performed with low polymerization shrinkage resin composite in comparison with traditional methacrylates-based resin composite. This systematic review was registered at Prospero data system (CRD42015023940). Studies were searched in the electronic databases PubMed, Web of Science, Scopus, Lilacs and EMBASE according to a predefined search strategy. The inclusion criteria were as follow: (1) randomized controlled clinical trials with at least six months of follow-up; (2) studies investigating composites with monomers designed to reduce polymerization shrinkage; (3) studies conducted with class I or II restorations in the permanent dentition; and (4) studies that assessed at least one of the following crite...

Method: The PubMed, EMBASE, PsycINFO, Scielo, Scopus, Web of Science, BBO, Lilacs and York databases were searched. Reference lists and citations of the selected studies were also searched. Two reviewers independently assessed titles, abstracts and full texts to determine study eligibility. Publications meeting the inclusion criteria were assessed for quality, and the data were extracted. Descriptive analysis of included publications was conducted, and themes were created to permit analysis by grouping relevant findings, from which effect size frequency (ESF) and effect size intensity (ESI) were calculated. Result: The search yielded 18,276 titles and abstracts, of which seven qualitative studies and 41 surveys (36,632 participants) remained after data extraction and interpretation.

Material e Métodos: Esta revisão sistemática foi registrada no PROSPERO (CRD42013004528). Quatro bancos de dados, bem como as listas de referências e citações das publicações incluídas foram pesquisados de acordo com as diretrizes do PRISMA, produzindo 6.387 títulos e resumos. Dois revisores realizaram a coleta de dados independentemente e um terceiro revisor foi incluído, se não houvesse consenso. Resultados: Nove artigos (2.742 participantes) permaneceram após a extração e interpretação dos dados. Um total de 14 resultados foram extraídos dos relatórios e foram agrupados em 4 temas que foram julgados semelhantes: tratamento, estética, função e bem-estar social. Os principais resultados baseados na frequência do tamanho de efeito foram: autopercepção da estética dos dentes (44%); harmonia dos dentes com outras estruturas da face (44%); alinhamento dos dentes anteriores (33%); maior conforto, ausência de dor e melhora na mastigação/ alimentação (33%); bem-estar social (33%); tratamento valeu a pena (33%). Conclusão: Apesar dos poucos trabalhos encontrados e do valor questionável da qualidade de alguns, a evidência aponta que o principal fator que leva à satisfação dos pacientes está relacionado à melhora estética dos próprios dentes. A mastigação, a ausência de dor, o bem-estar social e a maneira como o tratamento foi conduzido foram destacados como razões para a satisfação do paciente pós-tratamento ortodôntico.

Method: Ten patients, female gender, leukodermas, age-range11-23 years, Class II, undergoing orthodontic pre-treatment were randomly selected. Two side and front view photographs were taken after conclusion of treatment. For clinical-quantitative analyses, the angle of facial convexity, total angle of facial convexity, nasolabial, interlabial, mentolabial sulcus angles and angle of the inferior third of the face were evaluated, as well as the proportions between mean anterior facial height, inferior anterior facial height and proportion of anterior third of the face. For qualitative evaluation, semi-structured interviews were held with patients. For the survey, side and front view photographs of patients were examined by professionals, laypersons and students who classified them as acceptable, pleasant, or unpleasant. Result: Clinical evaluations showed that only one patient concluded treatment presenting all the numerical facial analysis variables equal to the values established in the literature. However, when asked, all the patients replied that they were satisfied with the results of treatment performed. Whereas, in the survey, patients were classified as 30% being pleasant, 60% as acceptable and 10% as unpleasant. Conclusion: The different methodologies evaluated differed as regards the post-orthodontic-treatment-result, and may be considered complementary for a more complete analysis of treatments performed.

Few studies have demonstrated the behavior of the condylar cartilage when the mandible is positioned posteriorly, as in treatments for correcting functional Class III malocclusion. The aim of this study was to assess the morphologic and histological aspects of rat condyles in response to posterior positioning of the mandible. Thirty five-week-old male Wistar rats were selected and randomly divided into two groups: A control group (C) and an experimental group (E) which received devices for inducing mandibular retrusion. The animals were euthanized at time intervals of 7, 21 and 30 days after the experiment had began. For histological analysis, total condylar thickness was measured, including the proliferative, hyaline and hypertrophic layers, as well as each layer separately, totaling 30 mea...
