RESUMEN
Abstract: This cross-sectional study aimed to determine the seroprevalence of SARS-CoV-2 infection among Brazilian dentists and its associated factors. Stratified random sampling of dentists from 33 administrative regions of the Federal District (Brazil) was performed. The presence of antibodies was verified by the OnSite COVID-19 IgG/IgM Rapid Test. Participants answered a survey about sociodemographic characteristics, exposure to COVID-19, and professional practice. A chi-square test was performed between serostatus and exposure variables. Mann-Whitney tests were carried out for quantitative variables. Odds ratio (OR) and 95% confidence intervals (95%CI) were calculated. A series of binomial logistic regression models was performed. The seroprevalence of SARS-CoV-2 infection among 324 selected dentists was 19.1%. There was a statistically significant association between seropositivity and previous confirmed diagnosis of COVID-19, loss of taste or smell, diagnosis of COVID-19 in a household member, and treatment of a patient with fever. Dentists with a previous confirmed diagnosis of COVID-19 had 29.5 [12.7-68.4] higher odds to exhibit positive serology test results. Dentists with confirmed diagnosis of COVID-19 in a household member had 2.5 [1.1-5.3] times higher odds to exhibit positive serology test results. Professionals with loss of taste or smell in the last 15 days had 5.24 [1.1-24.1] times higher odds to exhibit positive serology test results, and, for those who had treated patients with fever, there were 2.99 [1.03-8.7] times higher odds to exhibit negative serology test results. There was a similar prevalence rate of infection among dentists and in the general population. Nevertheless, this finding applies to the epidemiological situation in 2020, before the development of vaccines and the emergence of SARS-CoV-2 Delta variant.
RESUMEN
Introduction: Combination Syndrome (CS) is a pathological condition observed in maxillary complete denture (CD) and mandibular removable partial denture (RPD) wearers. Purpose: The aim of this study was to observe and measure the prevalence of CS signs in treatment-seeking wearers of maxillary CD associated or not with RPD (mandibular Kennedy Class I). The association between RPD wearing and the number of CS clinical signs was also evaluated. Material and method: The sample included 62 patients seen at the Department of Dentistry, Federal University of Rio Grande do Norte (UFRN). A clinical oral examination was conducted to assess the presence of specific clinical signs of CS as described by Kelly (1972): bone resorption in the maxillary anterior region, tuberosity overgrowth, palatal papillary hyperplasia, extrusion of mandibular anterior teeth and bone resorption in the mandibular posterior region. The chi-square test at the 95% level of significance was used to test the association between dependent and independent variables. Result: Mandibular resorption was the most frequent complication (93.5%). There was a statistically significant difference between RPD wearers and non-wearers with regard to extrusion of mandibular anterior teeth (p = 0.045). Conclusion: Within the limitations of the present study, a high prevalence of CS clinical signs was observed, but no association between RPD wearing and syndrome characteristics was found. .
Introdução: A Síndrome da Combinação (SC) é uma condição patológica associada aos pacientes usuários de prótese total maxilar e prótese parcial removível (PPR) mandibular. Objetivo: Observar e mensurar a prevalência dos sinais da Síndrome da Combinação encontrados em pacientes usuários de prótese total maxilar na presença ou ausência de PPR mandibular (Classe I de Kennedy); e averiguar uma possível associação entre a utilização de PPR e a prevalência dos sinais clínicos da síndrome. Material e método: A amostra foi composta por 62 pacientes atendidos no Departamento de Odontologia da Universidade Federal do Rio Grande do Norte (UFRN). O exame clínico intrabucal foi realizado para a verificação da presença ou ausência dos sinais clínicos específicos da Síndrome da Combinação, descrita por Kelly (1972): reabsorção óssea na região anterior da maxila, aumento das tuberosidades, hiperplasia papilar palatina, extrusão dos dentes naturais inferiores anteriores e reabsorção óssea posterior mandibular (variáveis dependentes). Para determinação da associação entre as variáveis dependentes e independentes (uso de PPR inferior e tempo de edentulismo superior), foi utilizado o teste qui-quadrado com significância de 95%. Resultado: A característica mais frequente foi a presença de reabsorção mandibular (93,5%). Quanto à associação entre o uso de PPR inferior e as características da Síndrome da Combinação, só houve diferença estatisticamente significativa entre portadores e não portadores de PPR com relação à extrusão dos dentes inferiores anteriores (p = 0,045). Conclusão: Dentro ...
