Objective: To analyze the factors associated with the proportion of abnormal results in screening mammograms. Methods: Ecological study, with data from DATASUS/SISCAN, Atlas Brasil do Desenvolvimento Humano, Fundação SEADE, and Sistema e-Gestor, from 2016 to 2019, of women aged 50 to 69 years in the 645 municipalities of São Paulo (Brazil). Independent variables were associated with the outcome: proportion of unsatisfactory coverage of abnormal test results (Breast Imaging Reporting and Data System - BI-RADS® 0, 4 and 5 proportion >10% of tests performed). Multiple Poisson regression was used. Results: Higher proportion of screening mammography (PR=1.20; 95%CI: 1.00;1.45), higher percentage of poor (PR=1.20; 95%CI: 1.07;1.36), low (PR=1.57; 95%CI: 1.38;1.78) and medium coverage of the Family Health Strategy (ESF) (PR=1.30; 95%CI: 1.09;1.52) were associated to the outcome. Conclusion: Socioeconomic and FHS coverage factors mediate the proportion of mammograms with abnormal results in public health services. Therefore, they are important aspects in the fight against breast cancer. RESUMEN Objetivo: Analizar los factores asociados a la proporción de resultados alterados en las mamografías de tamizaje. Métodos: Estudio ecológico, con datos de DATASUS/SISCAN, Atlas Brasil do Desenvolvimento Humano, Fundação SEADE y Sistema e-Gestor, de 2016 a 2019, de mujeres de 50 a 69 años en los 645 municipios de São Paulo (Brasil). Las variables independientes se asociaron con el resultado: proporción de cobertura insatisfactoria de resultados de pruebas alteradas (BreastImagingReporting and Data System - BI-RADS® 0, 4 y 5 proporción >10% de pruebas realizadas). Se utilizó la regresión de Poisson múltiple. Resultados: Mayor proporción de mamografía de tamizaje (RP=1,20; IC95%: 1,00;1,45), mayor porcentaje de mala (RP=1,20; IC95%: 1,07;1,36), baja (RP=1,57; IC95%: 1,38) ;1,78) y cobertura media de la Estrategia Salud de la Familia (ESF) (RP=1,30; IC95%: 1,09;1,52) se asociaron al desenlace. Conclusión: Factores socioeconómicos y de cobertura de la ESF median la proporción de mamografías alteradas en el servicio público. Por lo tanto, son aspectos importantes en la lucha contra CM.

Resumo Objetivo Avaliar as repercussões da pandemia de COVID-19 nos procedimentos realizados por um serviço público odontológico de urgência (SPOU). Métodos Estudo transversal, utilizando-se dados do SPOU de Piracicaba, SP, Brasil, relativos a dois períodos, anterior (fevereiro e março de 2020) e durante a pandemia (março e abril de 2020). Diferenças no perfil de atendimentos, entre os períodos pré-COVID-19 e COVID-19 selecionados, de acordo com sexo, idade e procedimentos odontológicos, foram analisadas pelo teste qui-quadrado de Pearson. Também foi calculado o tamanho do efeito Cramer's V. Resultados Houve redução de 51% no número de atendimentos, entre o período anterior (n=824) e o período da pandemia de COVID-19 observado (n=404). O percentual de exodontias reduziu-se, de 14,7 para 8,9%, enquanto o de selamento provisório de cavidades aumentou de 22,9 para 33,2%, entre ambos períodos. Conclusão A pandemia de COVID-19 repercutiu na quantidade e no padrão de procedimentos realizados pelo serviço odontológico de urgência do município.

Abstract Objective To evaluate the repercussions of the COVID-19 pandemic on procedures performed by a public urgent dental care service (PUDS). Methods This was a cross-sectional study, using data from the PUDS in Piracicaba, SP, Brazil, prior to the pandemic (February-March 2020) and during the pandemic (March-April 2020). Differences in the care profile between the pre-COVID-19 period and the COVID-19 period, according to sex, age and dental procedures were analyzed using Pearson’s Chi-square test. Effect size was also measured using Cramer’s V. Results There was a 51% reduction in the number of visits between the pre-COVID-19 period (n=824) and the COVID-19 period (n=404). The percentage of extractions reduced from 14.7% to 8.9%, while the percentage of temporary cavity fillings increased from 22.9% to 33.2%, between the two periods. Conclusion The COVID-19 pandemic had repercussions on the amount and pattern of procedures performed at the city’s urgent dental care service.

The aim of this study was to evaluate Knoop hardness of different shades of a resin cement light-cured directly or through ceramic discs, measured 15 min or 24 h after light exposure, and at different depths. Specimens of a commercial resin cement (Variolink Veneer) in seven shades, were fabricated in an elastomeric mold, covered with a mylar strip, a 0.7 mm thick ceramic disc (IPS e.max Press) was placed and the cement was light-activated for 20 s using a blue LED (Radii-Cal). The cured resin cement specimens were transversely wet-flattened to their middle portion and microhardness (Knoop) values were recorded at 15 min after light exposure and after deionized water storage at 37 ºC for 24 h. Five indentations were made in the cross-sectional area at 100 and 700 μm depths from the top surface. Ten specimens were made for each test conditions. Data were submitted to ANOVA split-plot design (shade, post-cure time, mode of activation and depth), followed by Tukey post hoc test (α=0.05). Significant differences for shade (p0.05) were found, except for shade x post-cure time (p0,05), exceto para a interação cor x tempo pós-ativação (p

No. of bitstreams: 0 Previous issue date: 2017 Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) Programa de Consolidacion de Indicadores – CEU-UCH Purpose: To evaluate dentin sealing (DS), micropermeability (MP), and dentin bond strength (BS) of HEMA-free adhesives after 24 h and one year of artificial saliva storage. Materials and Methods: Two HEMA-free (G-ae nial Bond and BeautiBond) and All-Bond 3 (the bottle of resin is HEMA-free) adhesives were tested. Adper Single Bond 2, a HEMA-containing adhesive, served as the control. All adhesives were applied according to the manufacturers' instructions and teeth were prepared for DS (n = 5), MP (n = 5), and BS testing (n = 10). DS under a pulpal pressure of 10 psi was performed at 4 time points (when smear layer was present, after EDTA treatment, after adhesive application, and after 1 year). MP was assessed using pulpal pressure of a 20-cm aqueous dye-solution column and confocal laser scanning microscopy. DS, MP, and BS were performed after 24 h or one-year storage. BS and DS data were statistically analyzed using two-way ANOVA, the Tukey-Kramer test (for BS) and Tukey's post-hoc test (for DS) (alpha = 0.05). A qualitative MP assessment was performed by comparing the accumulation of yellow dye within the resin-dentin interface. Results: Adper Single Bond 2 and All-Bond 3 completely sealed the dentin at 24 h and one year. G-ae nial Bond showed statistically significant DS reduction of approximately 15% after one year. BeautiBond showed no DS reduction after one year. The resin-dentin interface created using Adper Single Bond 2 and GA showed dye accumulation primarily after one year. The mean BS of All-Bond 3 was statistically significantly higher than that of other adhesives, while G-ae nial Bond and BeautiBond showed statistically significantly lower mean bond strengths than did Adper Single Bond 2 and All-Bond 3. After one-year storage, the mean BS was statistically significantly lower only for G-ae nial Bond. Conclusion: DS, MP, and BS were not influenced by the absence of HEMA in the tested adhesives.
