RESUMO
Objetivo: Analisar o impacto da pandemia da COVID-19 no atendimento odontológico do município de Manhuaçu/MG.Métodos: Coletou-se dados secundários por meio do software Sidim Saúde Pública dos procedimentos realizados antes e durante a pandemia. Realizou-se análise descritiva (porcentagens e médias) dos dados obtidos. Resultados: Os atendimentos de urgência e agendados diminuíram, respectivamente, cerca de 19% e 85%. Antes da pandemia, a média de procedimentos realizados referentes as especialidades dentística (103,4) e periodontia (97,4) eram os mais frequentemente realizados diariamente. No entanto, durante a pandemia, os procedimentos agrupados na categoria "outros" foram mais realizados, seguido por procedimentos de dentística e endodontia. Os procedimentos das especialidades de saúde coletiva, periodontia e dentística tiveram maior redução 100%, 97% e 95% respectivamente. Conclusão: A COVID-19 causou impacto significante nos atendimentos e procedimentos preventivos e curativos de eleição realizados pela equipe de saúde bucal em Manhuaçu.
Aim: To analyze the impact of the COVID-19 pandemic on dental care in Manhuaçu, MG. Methods: Secondary data were extracted from the Sidim database of Public Health. The procedures performed by dentists before and during the pandemic were collected. A descriptive analysis was performed (percentages and averages).Results: A decrease in emergency procedures and routine care of approximately 19% and 85%, respectively, was found. Before the pandemic, the average number of procedures performed on a daily basis was around 103.4 dental specialties and 97.4 periodontal procedures. However, during the pandemic, the most performed procedures were rapid testing for SARS-COVID-2 detection, temperature measurement, and blood pressure, followed by dental and endodontic procedures. A maximum decline in procedures was observed in public health specialties (100%), periodontics (97%), and dentistry (95%). Conclusion:COVID-19 had a significant impact on the dental care and preventive and curative procedures in the public health system of Manhuaçu.

PURPOSE: To evaluate the influence of a 2% chlorhexidine solution (CHX) on the bond strength and nano leakage of two self-etching adhesive systems on demineralized dentin over a 12-month period. MATERIALS AND METHODS: The middle dentin from sound third molars was exposed and demineralized in vitro. Twelve groups were formed using different adhesive systems (Clearfil Protect Bond [PB], Clearfil SE Bond [SE]) dentin treatment (with or without CHX application), and water-storage times (24 h, 6 and 12 months). Composite resin cylinders were bonded to the prepared dentin, and these specimens underwent microshear bond strength (µSBS) testing and nano leakage evaluation. µSBS data were submitted to a three-way ANOVA and Tukey's test. The failure mode and nano leakage were analyzed descriptively by score. RESULTS: There was a statistically significant interaction only between the adhesive system and CHX, and adhesive system and water-storage times. SE showed the lowest µSBS just at 24 h water-storage time regardless of CHX. A significant decrease in µSBS values after 6 months of water storage occurred in all of the groups and was maintained until 12 months. Adhesive failure increased with storage time. All groups showed nano leakage at the resin/dentin interfaces and an increased silver deposition was noticed after 6 and 12 months of water storage. The highest percentages of nano leakage were found in CHX groups. CONCLUSION: CHX did not interfere with µSBS values for either self-etching adhesive system, but water storage did. Bond strength decreased for both adhesive systems after 6 and 12 months, regardless of CHX application. Nano leakage increased with water-storage time and with CHX application.
