Aim: To evaluate the clinical performance of a composite resin (CR) and a resin-modified glassionomer cement (RMGIC) for the treatment of abfraction lesions. Methods: Thirty patients with abfraction lesions in at least two premolar teeth were selected and invited to participate in this study. All restorations were made within the same clinical time frame. One tooth was restored with CR Z100 TM (3M, St. Paul, MN, USA), and the other was restored with RMGIC Vitremer TM (3M). The restorations were assessed immediately and 1, 6 and 12 months after the restoration, using modified US Public Health Service (USPHS) criteria: marginal integrity, marginal discoloration, wear, retention, secondary caries and hypersensitivity. The statistical analysis was based on Friedman ANOVA test and Mann-Whitney test, considering p<0.05 for statistical significance. Results: Both materials demonstrated satisfactory clinical performance after one year. In the individual analysis of each material, there was a significant difference (p<0.05) in the criteria marginal integrity and wear, for both CR and RMGIC. RMGIC exhibited more damage one year after the restoration. Comparing both materials, it was found a significant difference only for marginal discoloration, while the RMGIC restorations showed the worst prognosis after a year of evaluation. There was no significant difference in the number of retentions, caries or hypersensitivity between CR and RMGIC. Conclusions: It was concluded that CR exhibited the best clinical performance according to the cost-effectiveness and evaluation criteria used in this study.

Este estudo objetivou avaliar a inserção da disciplina de Pacientes com Necessidades Especiais (PNE) na estrutura curricular dos cursos de Odontologia em funcionamento no estado do Rio Grande do Norte (RN). Trata-se de estudo transversal, exploratório e descritivo com abordagem quantitativa. As informações foram coletadas nos sítios web dos cursos. Foram encontrados dez cursos em funcionamento e cinco deles ofertavam a disciplina, sendo apenas um em modo optativo. A nomenclatura da disciplina e o semestre de oferta variou entre as instituições. Dois cursos possuem uma abordagem teórico/prática, um deles clínica e o restante teórica. Conclui-se que apenas as quatro instituições privadas oferecem de forma obrigatória o componente curricular relacionados a PNE durante a graduação, enquanto entre as públicas apenas uma oferta a disciplina, porém, de maneira optativa. Assim, é evidente a necessidade da inserção de conteúdos relacionados à assistência de pacientes especiais nos cursos de graduação em Odontologia do RN, atendendo às Diretrizes Curriculares Nacionais no tangente à formação de um profissional generalista.

RESUMO:O fator mais importante na manutenção da saúde periodontal é o adequado controle do biofilme dentário. Face às dificuldades no controle mecânico por parte dos pacientes, métodos alternativos ou complementares têm sido utilizados como coadjuvantes químicos do controle do biofilme, auxiliando no tratamento da gengivite. Dentre esses métodos alternativos, destaca-se a fitoterapia, através da utilização de plantas medicinais. Dessa forma, esse estudo faz uma revisão sistemática tendo como objetivo a busca, na literatura atual, de estudos que comprovem a eficácia de produtos fitoterápicos à base de aroeira no controle do biofilme dental auxiliando no tratamento da gengivite. Foi realizada busca computadorizada nos indexadores MedLine, Lilacs, BBO e Scielo no período de Setembro a Outubro de 2014. Os descritores de pesquisa utilizados foram "biofilme", "gengivite", "aroeira", "plantas medicinais" e "fitoterápicos", bem como seus correspondentes em língua inglesa. Através dos descritores utilizados, foram encontrados 54 artigos. Após a aplicação dos critérios de inclusão e exclusão, chegou-se a 08 artigos: 05 revisões, 01 estudo clínico randomizado, 01 estudo experimental e 01 estudo observacional descritivo. De acordo com os estudos analisados, a aroeira apresentou atividades antifúngica e antimicrobiana eficazes, bem como potencial efeito de redução do índice de sangramento gengival, o que justifica seu uso no tratamento da gengivite.Palavras-chave: aroeira, gengivite, plantas medicinais.ABSTRACT: The use of aroreira-based phytotherapics as a supporting tool in the treatment of gingivits: A systematic Review.The most important factor to keep periodontal health is proper control of biofilm. Given the difficulties in the mechanical control by patients, alternative or complementary methods have been used as chemical supporting of biofilm control, helping the treatment of gingivitis. Among these alternatives, there is the phytotherapy, through the use of medicinal plants. Thus, this study it is a systematic review and aims to seek, in the current literature, researches proving the effectiveness of aroeira herbal products in the control of dental biofilm, assisting in the treatment of gingivitis. A computerized search was conducted in Medline, Lilacs, Scielo and BBO, from September to October of 2014. The search words used were "biofilm", "gingivitis", "aroeira", "herbal medicines" and "phytotherapics" in Portuguese and English language. Through this method, 54 articles were found. After applying the inclusion and exclusion criteria, the research reached 08 items: 05 reviews, 01 randomized clinical trial, 01 experimental study and 01 descriptive observational study. According to the analyzed papers, the aroeira demonstrated effective antifungal and antimicrobial activities, as well as a potential reduction impact on gingival bleeding index, which would justify its use in the treatment of gingivitis. INTRODUÇÃOA formação do biofilme dentário é o fator desencadeante dos processos patológicos que acometem a estrutura...

Objective: To evaluate the antibacterial activity of four formulations of calcium hydroxide paste against microorganisms commonly found in infected root canals. Methods: To evaluate antibacterial activity through the agar diffusion method, pastes of calcium hydroxide were made from its pro-analysis form, diffused into four separate vehicles: distilled water, camphorated p-monochlorophenol, propylene glycol and Otosporin®, testing the antimicrobial activity of these on strains of Staphylococcus aureus, Bacillus subtilis and Enterococcus faecalis. After the incubation period, the presence or otherwise of inhibition zones were observed and their sizes in three stages: 24h, 48h and 72h. With this data, the median between the four dishes was obtained and the consequent value was submitted to Kruskal-Wallis nonparametric statistical analysis, with post-tests of Mann-Whitney and Bonferroni correction, at a significance level of 5%. Results: Only pastes with camphorated p-monochlorophenol and Otosporin vehicles caused the formation of significant inhibition zones, with medians of 8.0 mm. Against the strains of Enterococcus faecalis, only pastes with the camphorated p-monochlorophenol vehicle resulted in the formation of significant inhibition zones, with a median of 3.0 mm. Conclusion : Otosporin and CMCP vehicles provide greater antimicrobial potential to calcium hydroxide against the studied bacteria. However, only the Ca(OH)2 and CMCP combination was effective against all the strains, and can thus be regarded as the paste formulation with the greatest antimicrobial effectiveness in this study.
