Factors Associated with SARS-CoV-2 Infection among Oral Health Team Professionals

ABSTRACT Objective: To analyze the factors associated with the SARS-CoV-2 infection among oral health professionals. Material and Methods: This was a cross-sectional study in the city of São Paulo, São Paulo State, Brazil. Professionals from three different categories were included: dental surgeons (DS), dental assistants (DA), and dental hygienists (DH). A questionnaire was created on a digital platform and sent via institutional email to each subject. The questionnaire contained 32 questions about sociodemographic, work, and behavior factors. The data about SARS-CoV-2 infection was confirmed through RT-PCR exams. Descriptive (absolute and relative frequencies) and inferential analyses (chi-squared or Fisher's exact test) (p<0.05) were performed. Results: There was a SARS-CoV-2 infection prevalence of 3.8% for DS, 30.0% for DH, and 33.3% for DA. SARS-CoV-2 was associated with a lower income (p=0.027), a lower education level (p=0.011), the category of technical professionals (DA and DH) (p=0.025), and using public transportation to commute to work (p=0.009). Conclusion: Sociodemographic factors like lower income and education levels and work factors like job category and public transportation were associated with COVID-19 among professionals on the oral health teams.

Sociodemographic factors associated with pregnant women's level of knowledge about oral health / Fatores sociodemográficos associados ao grau de conhecimento em saúde bucal de gestantes

ABSTRACT Objective To evaluate knowledge on oral health and associated sociodemographic factors in pregnant women. Methods A cross-sectional study with a sample of 195 pregnant women seen at the Primary Care Unit Paraisópolis I, in São Paulo (SP), Brazil. For statistical analysis, χ2 or Fisher's exact test and multiple logistic regression were used. A significance level of 5% was used in all analyses. Results Schooling level equal to or greater than 8 years and having one or two children were associated with an adequate knowledge about oral health. Conclusion Oral health promotion strategies during prenatal care should take into account sociodemographic aspects.

RESUMO Objetivo Avaliar o conhecimento em saúde bucal e os fatores sociodemográficos associados em gestantes. Métodos Estudo com delineamento transversal, com amostra de 195 gestantes atendidas na Unidade Básica de Saúde de Paraisópolis I, em São Paulo (SP). Para a análise estatística, utilizou-se teste χ2 ou teste exato de Fisher e a regressão logística múltipla. Assumiu-se um nível de significância de 5% para todas as análises. Resultados Escolaridade igual ou maior a 8 anos de estudo e presença de um a dois filhos estiveram associadas a conhecimento adequado sobre saúde bucal.

Resistência à fratura de dentes com retentores intra-radiculares fundidos / Fracture strength of teeth with cast intraradicular retainers

Com objetivo de verificar a resistência à fratura de dentes reconstruídos em retentores intra-radiculares metálicos fundidos, 15 caninos foram preparados, formando-se três grupos de acordo com o remanescente dental (RD) e a altura do núcleo de reconstrução (N): totais RD = 0, N = 7 mm), parciais (RD = 3 mm, N = 4 mm) e incisais (RD = 5 mm, N = 2mm). Submetidos ao teste de compressão através da máquina Kratos, os dentes reconstruídos apresentaram a seguinte ordem decrescente de valores: totais (517,75 kgf); parciais (342,10 gf) e iniciais (103,00 kgf) com p < 0,01. Pôde-se concluir que dentes tratados endodonticamente podem ser restaurados com retentores intra-radiculares fundidos, apresentando boa resistência à fratura, independentemente das dimensões RD e N.
