O objetivo deste estudo foi avaliar a percepção estética por estudantes de odontologia em relação a diferentes fotografias de situações periodontais clássicas relacionadas à margem gengival. Esse foi um estudo observacional transversal envolvendo 161 estudantes de odontologia. Cinco situações clínicas definidas em fotografias retiradas de livros foram apre-sentadas aos estudantes. Os casos envolviam periodonto inalterado, sorriso gengival, desnível gengival, recessão gengi-val localizada e recessão gengival generalizada. A percepção estética foi avaliada por uma escala visual analógica (EVA). As comparações das diferentes situações foram realizadas por ANOVA de uma via, com teste pos-hoc de Tukey. Os resultados demonstraram diferenças estatisticamente significativas entre os grupos (p<0.05). A melhor estética foi atribuída ao periodo...

Participaram 14 pacientes entre 35 e 61 anos, os quais, por sorteio, foram divi-didos em grupo teste (GT) e placebo (GP). No GT foi feita aplicação tópica subgengival de 10 ml de triclosan por sítio e no GP, com placebo. Foi realizada 1 irrigação por sítio a cada 14 dias durante 70 dias (total de 6 irrigações). Foram avaliados Índice de Placa (IPL), Índice Gengival (IG), Sangramento à Sondagem (SS), Profundidade de Sondagem (PS) e os Níveis de Inserção Clínica (NIC). Os exames clínicos foram realizados no início, aos 42 dias de irrigação e 30 dias após a última irrigação ter sido real-izada. Medianas e intervalos interquartis dos IPl, IG e SS foram analisados através do T...

Pre- and post-treatment intra-oral photographs and orthodontic study models of 178 Caucasian adolescents (101 female, 77 male) were used. All subjects were treated with fixed appliances. The subjects had mean ages of 11.41 (SD: 1.83) years and 14.91 (SD: 1.78) years on their initial and final records respectively. The latter were taken 28 days or more after the appliances had been removed. The inclusion criteria were: Angle Class I or Class II malocclusion (with or without transverse and/or vertical discrepancies); nonextraction treatment; less than 4 mm crowding or spacing; fully erupted lower incisors and good periodontal health. The intercanine widths and the positions of the gingival margins relative to the maximum curvatures of the labial surfaces of the lower canines and incisors were measured with d...

Previous reports based on data from other countries link cannabis smokers to worse periodontal health status. The aim of this study is to describe self-reported gingival and periodontal health status and estimate the prevalence of periodontitis among Uruguayan cannabis club members. A cross-sectional study was conducted on a convenience sample of cannabis club members in Uruguay. A survey was used to gather sociodemographic data and information on oral hygiene, use of cannabis and other drugs, and self-reported gingival and periodontal health status. Eight questions validated in Spanish were used to estimate the prevalence of total periodontitis and severe periodontitis, based on two previously implemented predictive models. The survey was completed by 50 people, of whom 68% were male and 78% were in the 20-40 year age range. Base...

Quatorze participantes periodontalmente saudáveis (20-35 anos de idade) foram incluídos no estudo. A goma teste 1 (TG1) continha sacarose e a goma teste 2 (TG2) continha xilitol e citrato de zinco. Duas séries de testes foram realizadas com um desenho duplo-cego cruzado. Após a abstenção de higiene oral noturna, CSV foram medidos antes e 5, 15, 30, 45 e 60 minutos após o ato de mascar as gomas. Na segunda série, a produção de CSV foi monitorada antes e até 30 minutos após um bochecho com cisteína a 6mM isoladamente e quando do ato de mascar as gomas. Para o primeiro teste, os resultados foram analisados através de ANOVA de medidas repetidas para comparações intra-grupo e teste t para amostras pareadas nas comparações inter-grupo. Na segunda série, o percentual...

Também foram registrados o Índice de Placa (IP), Índice de Gengival (IG), PS, NIC e SS dos dentes remanescentes. A perda óssea periimplantar foi avaliada a par-tir de radiografias periapicais. Mensurações do nível ósseo nas radiografias panorâmicas pré-operatórias e finais permitiram estimar a perda óssea associada a dentes e a fazer compara-ções com a perda óssea em torno dos implantes. Nenhum dos indivíduos examinados apresentou perda de implantes por falha tardia no período. N...

Groups OB and OB+PD received cafeteria diet for 17 weeks. After they had acquired obesity (week 12), periodontal disease was induced by placing a silk ligature on the maxillary right second molar of groups PD and OB+PD. During the experimental period, body weight and Lee index were assessed. Mean alveolar bone loss (ABL) was evaluated, and aortas were prepared for histometric analysis of the aortic wall by ImageJ software. Body weight and Lee index increased in rats exposed to cafeteria diet. Mean ABL was higher in Groups PD and OB+PD than in control and OB (p<0.05). ABL was 18% higher in Group OB+PD than in Group PD, with statistically significant difference (p<0.001). Aortas were ...

O método de investigação foi predominantemente qualitativo (estudo de caso). Foram convidados a participar do estudo todos os estudantes do 1º ao 10º semestre do curso. A coleta de dados envolveu a análise de documentos e aplicaçãode questionário semiestruturado. Os dados objetivos foram analisados pelo software estatístico SPSS versão 18.0 e os relatos foram interpretados por meio da análise de conteúdo. Participaram do estudo 360 estudantes (taxa de resposta 88,5%), sendo a maioria mulheres (69,2%), jovens (58,1% com idade entre 17 a 22 anos), solteiros (96,4%) e sem filhos (98,3%). Grande parte dos estudantes acredita estar recebendo uma sólida formação para atuar no mercado detrabalho e mostrou-se satisfeito com o curso. Como potencialidades, os estudantes destacaram o atualcurrículo que enfatiza a humanização ...

"Kissing molars" (KMs) are an uncommon tooth impaction involving 2 severely tipped mandibular molars with their occlusal surfaces positioned crown to crown, with the roots pointing in opposite directions. Orthodontic uprighting of KMs has not been a usual treatment protocol, and it can be a challenging task due to the severe tipping and double impaction, requiring efficient and well-controlled uprighting mechanics. An innovative skeletally anchored cantilever, which uses the torque principle for uprighting tipped molars, is suggested. This torqued cantilever is easy to manufacture, install, and activate; it is a well-known torque that is effective for producing root movement. A successful treatment of symptomatic KMs, involving the first and second molars, was achieved with this cantilever. Thus, clinicians should consider the suggested uprighting mechanics and orthodontic device as a ...

On June 5, 2017, we searched PubMed, Cochrane, SCOPUS, Web of Science, LILACS, ProQuest, Open Grey, and Google Scholar databases. Randomized clinical trials in which pregnant women with chronic periodontitis underwent nonsurgical periodontal therapy, compared with an untreated group, tested for inflammatory biomarkers, and followed till delivery were included. Primary outcomes were preterm birth, low birth weight, and preeclampsia. Meta-analysis was performed with 5.3.5 version of Review Manager software. We found 565 references in the databases, 326 after duplicates removal, 28 met criteria for full text reading, and 4 met eligibility criteria for quantitative and qualitative synthesis. Intra-pregnancy nonsurgical periodontal therapy improved periodontal clinical parameters (periodon...
