Tendência histórica da exodontia de dentes permanentes no Brasil: análise de uma série de 15 anos / Historical trend of extraction loss in Brazil: an analysis of 15 years of series

RESUMO

Introdução: a perda dentária é considerada um problema de saúde pública. Estudos de série temporal que avaliam a influência das condições de desenvolvimento humano e do acesso a serviços de saúde sobre essas perdas dentárias são escassos. O estudo objetivou descrever a tendência das exodontias de dentes permanentes no Brasil entre 1998 e 2012, comparar essas tendências em municípios que apresentam Índice de Desenvolvimento Humano (IDH) diferentes; com acesso e cobertura de atenção primária e secundária distintos. Metodologia: estudo de série temporal realizado entre 1998 e 2012, com dados do Sistema de Informação em Saúde do Sistema Único de Saúde. Foram calculadas duas taxas anuais de exodontias e analisadas de forma estratificada de acordo com três parâmetros...

ABSTRACT

Background: Tooth loss is considered to be a public health problem. Time-series studies that assess the influence of social conditions and access to health services on tooth loss are scarce. Objective: This study aimed to examine the time series of permanent tooth extraction in Brazil between 1998 and 2012 and to compare these series in municipalities with different Human Development Index (HDI) scores and with different access to distinct primary and secondary care. Research Design: Time-series study was performed between 1998 and 2012. Subjects: Secondary data from the Brazilian National Health Information System. Measures: Two annual rates of tooth extraction were calculated and evaluated separately according to three parameters: the HDI, the presence of a Dental Specialty Center, and coverage by Oral Health Teams. The time series was analyzed using a linear regression model. Results: An overall decrease in the tooth-loss tendencies during this period was observed, particularly in the tooth extraction rate during primary care procedures. In the municipalities with an HDI that was lower than the median, the average tooth-loss rates were higher than in the municipalities with a higher HDI. The municipalities...
