0503/2009 - Séries de procedimentos odontológicos realizadas nos serviços públicos brasileiros, 1994-2007 Time series analysis of dental care procedures in the Brazilian public services, 1994-2007
Os objetivos foram descrever o padrão temporal de taxas mensais de cinco procedimentos odontológicos dos serviços públicos do Brasil e avaliar mudanças nas tendências das taxas entre 1994 e 2007. Os dados foram obtidos no Sistema de Informação Ambulatorial (SIA-SUS). Foram calculadas as taxas mensais de procedimentos odontológicos coletivos, procedimentos preventivos, restauradores, exodontias e total de procedimentos odontológicos para o Brasil, e a taxa total de procedimentos odontológicos para cada macro-região. As séries foram analisadas por médias móveis e modelos SARIMA. Observou-se decréscimo nas tendências das taxas de restaurações e exodontias. As principais alterações foram observadas entre janeiro de 1998 e janeiro de 2000. Em outubro de 1999, a taxa total de procedimentos por mil habitantes aumentou em 30,5 procedimentos ou 55%, e após a inclusão das Equipes de Saúde Bucal (ESB) o aumento foi de 5,9 procedimentos ou 6.9%. Encontrou-se um forte padrão sazonal. A comparação entre macro-regiões mostrou que a região Norte possui características diferentes das demais. Conclui-se que as principais alterações nas séries coincidem com o período tardio de municipalização da saúde, mas houve um aumento na taxa total de procedimentos com o incentivo a inclusão da ESB-PSF.

Abstract:
The objectives of this study were to describe monthly time series of five dental care procedures rates in the Brazilian public health system and to assess changes in rates of dental procedures from 1994 to 2007. Data was collated from the “Sistema de Informação Ambulatorial” (SIA-SUS). It was calculated monthly rates of total dental care procedures, preventive procedures, collective procedures, restorations and extractions for the whole country and total procedures for each of macro-region. Time series were analyzed with moving averages and SARIMA models. There was a decrease in the series of restorative care and tooth extraction. The major impact in the series occurred between January of 1998 and January of 2000. In October 1999, the total rate of dental procedures per a thousand inhabitants increased 30.5 procedures or 55%, and after the introduction of the Oral Health Team (ESB) in the Health Family Program (PSF) in December of 2000, the increase was 5,9 procedures or 6.9%. There was also a strong seasonal pattern, apart from the North region. It can be concluded that the main changes occurred due to the municipalisation process, but after the introduction of the ESB-PSF, there was a smaller increase in the rate of total dental procedures. Key words: Family Health Program. Health Services Accessibility. Time Factors.
