Association of Papacarie Duo® and low-level laser in antimicrobial photodynamic therapy (aPDT).

Dental caries is a multifactorial, non-communicable disease. Effective treatment options for minimally invasive removal of carious tissue include Papacarie Duo® gel and antimicrobial photodynamic therapy (aPDT). aPDT involves a combination of a light source and photosensitizer. Given that Papacarie Duo® contains a percentage of blue dye, this study aims to explore the antimicrobial potential of Papacarie Duo® when associated with a light source against Streptococcus mutans strains. The chosen light source was a low-power diode laser (λ = 660 nm, E = 3 J, P = 100 mW, t = 30 s). To assess antimicrobial capacity, planktonic suspensions of Streptococcus mutans were plated on Brain Heart Infusion Agar (BHI) to observe the formation of inhibition halos. The studied groups included methylene blue (0.005%), Papacarie Duo®, distilled water (negative control), 2% chlorhexidine (positive control), Papacarie Duo® + laser, and methylene blue (0.005%) + laser. Following distribution onto plates, each group was incubated at 37 °C for 48 h under microaerophilic conditions. Inhibition halos were subsequently measured using a digital caliper. The results showed that chlorhexidine had the greatest antimicrobial effect followed by the group of irradiated methylene blue and irradiated Papacarie Duo®. All experimental groups demonstrated antimicrobial potential, excluding the negative control group. The study concludes that Papacarie Duo® exhibits antimicrobial properties when associated with a low-power diode laser.

Impacto da COVID-19 nos procedimentos odontológicos do Sistema Único de Saúde em Manhuaçu: estudo transversal baseado em dados extraídos do sistema Sidim Saúde Pública entre 2018 e 2021 / Impact of COVID-19 on dental procedures in the Unified Health System in Manhuaçu: Cross-sectional study with data extracted from the Sidim - Saúde Pública system between 2018 and 2021

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.
