Influence of final irrigation protocols and type of resin cement on bond strength of glass fiber posts in root dentin previously treated with photodynamic therapy.

INTRODUCTION: This study aimed to evaluate the influence of final irrigation protocols and type of resin cement on the bond strength of glass fiber posts (GFPs) in root dentin previously treated with photodynamic therapy (PDT). METHODS: One hundred root canals were prepared up to #4 Gates Glidden drill to receive the GFPs. All samples were subjected to PDT, and randomly divided into five groups (n = 20) according to final irrigation protocol: distilled water + ultrasonic activation [US]; 17% EDTA; QMix; 17% EDTA + US; and QMix + US. Each group was randomly divided into 2 subgroups (n = 10) according to the type of resin cement used for cementation of GFPs: Rely-X ARC dual-resin; or Rely-X U200 (#M, St Paul, MN, USA) self-adhesive resin cement. Bond strength was evaluated using the push-out test. Failure patterns were observed under an optical microscope. Bond strengths were compared using two-way ANOVA, followed by the Tukey post-hoc test; failure modes were compared using the chi-squared test (α = 5%). RESULTS: The use of US over final irrigants improved the bond strength of GFPs, regardless of resin cement used (p < 0.05). The type of resin cement did not influence the bond strength of GFPs (p < 0.05). There was a higher predominance of cohesive failure in all groups, regardless of resin cement tested (p < 0.05). CONCLUSIONS: The use of US on final irrigation improved the bond strength of GFPs, while the type of resin cement (dual or self-adhesive) did not influence the bond strength of GFPs in root dentin previously treated with PDT.

Influence of final irrigation protocols and endodontic sealer on bond strength of root filling material with root dentin previously treated with photodynamic therapy.

INTRODUCTION: The aim of this study was to evaluate the influence of final irrigation protocols and endodontic sealer on bond strength of root filling material on root dentin previously treated with photodynamic therapy (PDT). METHODS: One hundred root canals were prepared up to #F3 file of Pro-Taper system to receive the root filling material. All samples were submitted to PDT and randomly divided into five groups (n = 20) according to final irrigation protocols: Group 1-distilled water + ultrasonic activation (US); Group 2-17% EDTA; Group 3-QMix; Group 4-17% EDTA + US; Group 5-QMix + US. Each group was randomly divided into two subgroups (n = 10), according to the endodontic sealer used for cementation of gutta-percha points: AH Plus or MTA Fillapex. The bond strength was evaluated by a push-out test. The patterns of failure were observed under optical microscopy. The bond strength was evaluated using a two-way Anova followed by the Tukey post-hoc test, and the failure mode was evaluated using the chi-square test (α = 5%). RESULTS: The use of 17% EDTA and QMix associated or not to US improved the bond strength of root filling material with either endodontic sealer (p < 0.05). AH Plus showed higher bond strength than MTA Fillapex (p < 0.05). There was a higher predominance of cohesive failure in all groups, regardless of the tested final irrigation protocols and endodontic sealer (p < 0.05). CONCLUSIONS: The use of 17% EDTA and QMix, regardless of association with US, and the use of AH Plus improve the bond strength of the root filling material on root dentin previously treated with PDT.

Association between Dental Caries and Socioeconomic Factors in Schoolchildren--A Multilevel Analysis.

This study aimed to assess the association between dental caries, socioeconomic individual and contextual factors in 12-years-old children. A representative sample of 1,134 children enrolled in public schools from Santa Maria, RS, Brazil, was obtained from a multistage random sampling. Four calibrated dentists examined participants at schools. Data about dental caries (DMF-T index) and dental plaque (present or absent) were assessed. Children's parents or guardians answered questions regarding their demographics and socioeconomic status. Context variables were also collected from official publications of the city. Data analyses were performed using multilevel logistic regression models. Caries prevalence in this sample (DMF-T≥1) was 49.9% (95%CI: 45.05% - 54.77%), and mean DMF-T was 1.15 (95%CI: 1.01-1.29) with 0.068 standard error. Children of the 3rd and 2nd tertile of income represented by the rich and intermediate categories, showed, respectively, a 50% (OR 0.50: CI95 % 0.35-0.71) and 39% (OR 0.61: CI95% 0.45-0.82) lower chance to present untreated caries compared with the poorest portion of the sample represented by the 1st tertile of income. Regarding the context covariates, children from lower income neighborhood presented a higher chance for having untreated dental caries compared with their counterpart (OR 1.70: CI95% 1.19 to 2.43). Inequalities in the distribution of dental caries continue affecting children from poorer socioeconomic profiles. There is need for planning public interventions for oral health promotion that take into account individual and contextual socioeconomic characteristics.

Resumo Esta pesquisa teve como objetivo avaliar a associação entre cárie dental e fatores socioeconômicos individuais e contextuais em crianças de 12 anos de idade. Uma amostra representativa de 1.134 crianças matriculadas em escolas públicas de Santa Maria, RS, foi obtida a partir de uma amostragem aleatória em duplo estágio. Quatro dentistas calibrados examinaram os participantes nas escolas. Foram avaliados dados sobre cárie dentária (índice CPO-D) e placa dentária (presente ou ausente). Os pais ou responsáveis pelos adolescentes responderam questionários sobre status socioeconômico e sociodemográficos. Variáveis contextuais também foram coletadas através de publicações oficiais do município. Os dados foram analisados utilizando-se modelos multiníveis de regressão logística. A prevalência de cárie da amostra (CPO-D≥1) foi 49.9% (95%IC: 45.05% - 54.77), e a média de CPO-D foi de 1.15 (95%IC: 1.01-1.29) com 0.068 de erro padrão. As crianças do 3º e 2º tercil de renda representado pelas categorias ricas e intermediárias apresentaram respectivamente 50% (OR 0,50: IC95% 0,35-0,71) e 39% (OR 0,61: IC95% 0,45-0,82) menor chance de apresentarem cárie não tratada em comparação com a porção mais pobre da amostra representada pelo 1º tercil de renda. Em relação à variável contextual "renda média do bairro", crianças que viviam em bairros com menor renda apresentaram uma chance 70% (OR 1,70: IC95% 1,19-2,43) maior de ter cárie dentária não tratada, quando comparadas com aquelas que viviam em bairros de maior renda. Desigualdades na distribuição da cárie dentária continuam afetando as crianças dos perfis socioeconômicos mais pobres. Os resultados mostram a necessidade de planejamento de intervenções públicas que visem a promoção da saúde bucal que levem em conta as características socioeconômicas individuais e contextuais.

Associated injuries in patients with maxillofacial trauma at the hospital são vicente de paulo, passo fundo, Brazil.

OBJECTIVES: This study aimed to identify the occurrence, type and severity of body injuries associated in patients with facial trauma, referred to the Hospital São Vicente de Paulo (HSVP) in the city of Passo Fundo - RS, Brazil. MATERIAL AND METHODS: The study analyzed medical records of 1385 patients who were treated in the Department of Oral and Maxillofacial Surgery at HSVP during the period from 1991 to 2010. RESULTS: According to the results of this study we observed that 35% of cases of facial fractures were associated with a body injury. It was recorded a higher incidence of facial fractures in the male population (82.6%), aged between 20 and 39 years. The main etiologic factors for this association were car accidents, falls and assaults. Most fractures were recorded in the mandible and the main body injury found was the abrasion associated in some region of the body, however, when considering fractures of the face middle third the main body injury was more associated with cranioencephalic trauma. CONCLUSIONS: Concomitant injuries in areas other than the face should be expected first and foremost after high-speed trauma mechanisms and in association with severe facial fractures. The results underscore the importance of multiprofessional collaboration in diagnosis and sequencing of treatment who have sustained facial fractures.
