These findings challenge the belief that unidirectional systems always provide acceptable airborne bacterial counts.

This study evaluated the influence of irrigation tip, root canal curvature and final apical diameter on periapical debris and irrigant extrusion during root canal instrumentation. After being classified as mildly or moderately curved, the mesiobuccal root canals of 90 human molars were instrumented. The teeth were allocated into three groups according to the used needle type: a flat open-end needle (Group 1), a side-vented needle (Group 2) or a double side-vented needle (Group 3). The amount of extruded material after instrumentation was calculated for each group. The differences in irrigant and debris extrusion between the experimental groups were analyzed with the Mann-Whitney U test. Irrigation tips and final instrument diameter differences were analyzed with the Kruskal-Wallis test. Multiple groups were compared using the Mann-Whitney U-test with a Bonferroni correction at α=0.05. The amount of extruded material from the double side-vented needle was significantly less than the open-ended flat needle (p=0.008), but there was no difference compared to the side-vented needle (p=0.929). The results showed no effect of root curvature and final apical diameter on the amount of irrigant and debris extrusion (p>0.05). The double side-vented needles generated the least material extrusion to the periapical tissues. Irrigation needle type had the greatest influence on periapical irrigant and debris extrusion and the double side-vented needles may be safely used during endodontic therapy.

Objective. The aims of this study were to evaluate the periodontal health of pregnant women and to investigate the association of periodontal status with demographic and socioeconomic characteristics, as well as medical and dental history. Materials and Methods. A total of 311 pregnant women were interviewed to obtain sociodemographic data along with medical and dental histories. Clinical examinations were performed to record the presence of visible plaque, gingival bleeding, and caries activity. The periodontal condition was evaluated by Community Periodontal Index of Treatment Needs (CPITN) in one tooth of each sextant (16, 11, 26, 36, 31, and 46). Results. After the adjustment analysis, the presence of visible plaque remained the main determinant of gingival bleeding (OR = 2.91, CI = 1.91–4.48). First-trimester pregnancy status was also a predictor, with a lower prevalence of gingival bleeding observed in the second (OR = 0.87, CI = 0.77–0.99) and third (OR = 0.82, CI = 0.73–0.93) trimesters. Conclusion. In pregnant women, the presence of dental plaque and first-trimester pregnancy status were the main implicated factors predicting gingival bleeding.

The present study demonstrated no association between maternal periodontitis and PTB/LBW.

Este estudo objetivou conhecer as contribuições da arteterapia na reabilitação de usuários de um Centro de Atenção Psicossocial (CAPS). Trata-se de uma pesquisa qualitativa realizada em 2016, por meio da aplicação de entrevista semiestruturada. Os dados foram analisados utilizando-se a técnica da análise temática.  A partir da análise dividiu-se os resultados em três categorias: desenvolvimento das oficinas terapêuticas, vínculo e participação e contribuição das oficinas terapêuticas na vida dos usuários. Observa-se que as oficinas terapêuticas promoveram a inclusão dos usuários e criação de vínculo, resultando em melhor qualidade de vida. Também verificou-se que os usuários demonstram afeto ao serviço e aos profissionais, e que as oficinas terapêuticas são benéficas para a saúde dos mesmos, ao passo que contribuem para bons relacionamentos familiares e sociais. Dessa forma a construção desse estudo proporcionou a compreensão de que a arteterapia tem um papel fundamental na vida dos usuários, contribuindo para sua reabilitação social.
