RESUMO
Introdução: A AIDS (Síndrome da Imunodeficiência Adquirida) é a doença causada pela infecção do Vírus da Imunodeficiência Humana (HIV) e é uma infecção sexualmente transmissível. O HIV é um retrovírus, classificado na subfamília dos Lentiviridae. Atualmente, ainda ocorrem casos de discriminação em consultórios odontológicos a pacientes portadores de HIV/AIDS, apesar de todas as informações sobre a doença, na hora do atendimento os profissionais ainda possuem receio e dúvida quanto ao protocolo de atendimento. Objetivo: Avaliar os aspectos éticos do atendimento odontológico de pacientes portadores HIV/AIDS na cidade de Imperatriz-Maranhão, sob a percepção dos mesmos. Material e Método: Foi aplicado um questionário estruturado a 100 pacientes portadores de HIV/AIDS que estavam em tratamento no Centro de Atenção Psicossocial (CAPS) do município de Imperatriz- MA, CAPS III e CAPS AD III, entre os meses de março e abril de 2019. Resultado: Os participantes relataram que sofreram discriminação (41% - 41) em algum momento do atendimento odontológico, 85% (85) dos pacientes não informariam ao cirurgião-dentista que é portador do HIV, sendo o constrangimento (14% - 14) o principal motivo para não informar. Conclusão: O índice de discriminação nos atendimentos odontológicos a pacientes portadores HIV/AIDS no município de Imperatriz-MA é elevado. Há necessidade dos cirurgiões-dentistas buscarem atualizar-se sobre o vírus HIV e a doença AIDS, e sobre aspectos éticos e legais do atendimento a pacientes portadores dessa morbidade, para garantir um atendimento seguro, de qualidade e humanizado.

To evaluate the influence of rewetting solutions on bond strength to root dentin of conventional gutta-percha (GP) or niobium phosphate glass-based gutta-percha (GNb) associated with a bioceramic sealer. The root canals of 80 human mandibular premolars were prepared using nickel-titanium instruments and irrigation with sodium hypochlorite and EDTA. The teeth were randomly divided into four groups according to the gutta-percha used: GNb or GP associated with EndoSequence BC Sealer (BC) and the solution for rewetting dentin before filling (distilled water; phosphate buffer saline solution - PBS; simulated body fluid - SBF; or no solution). The root canals were filled with a single cone using warm vertical condensation. Micropush-out bond strengths associated with the filling materials in slices from middle root thirds was determined 30 days after root filling. The failure mode was analyzed with stereoscopic lens. The data were statistically analyzed by two-way ANOVA and Holm-Sidak test (p < 0.05). There was significant difference in the types of gutta-percha (p < 0.001) and in the different rewetting solutions (p = 0.003). The interaction between gutta-percha and rewetting solutions was not significant (p = 0.53). The SBF solution provided an increase in bond strength for both gutta-percha solutions. The GNb+BC (3.42 MPa) association increased bond strength when compared with GP+BC (2.0 MPa). The use of SBF as a dentin rewetting solution increased bond strength in the groups studied. Association of GNb with bioceramic sealer was beneficial, increasing the bond strength to dentin when compared with the association with GP.

OBJECTIVES: To evaluate the influence of dentine on the pH of different medications in standardized simulated canals. MATERIALS AND METHODS: Forty resin blocks were divided into groups with and without dentine powder, as follows: 2% chlorhexidine gel; 2% chlorhexidine gel associated with calcium hydroxide PA; calcium hydroxide PA delivered in propylene glycol 600; and NPG delivered in distilled water. The dentine powder was obtained from the root dentine of bovine teeth and added to the medications. The simulated canals were placed in containers with 1.5 mL of deionized water and pH was monitored in multiple intervals, up to 30 days. The mean pH values were calculated and submitted to statistical analysis using paired Student's t-test and ANOVA complemented by the Tukey test (p < 0.05). RESULTS: There was no statistical difference between the groups with and without dentine powder (p > 0.05). The pH values of calcium hydroxide were significantly higher than those of NPG in the first 24 hours (p < 0.05). After 7 days, both behaved in a similar manner. CONCLUSION: The addition of dentine powder to the medications evaluated did not alter the pH of the external solution in any of the time points tested.
