Exodontias no Sistema Único de Saúde em Minas Gerais: uma série temporal de 15 anos

Abstract

Aim: To evaluate the time-series of permanent tooth extraction in the state of Minas Gerais between the years 1998 and 2012. Methods: This is a time-series study of permanent tooth extraction in the state of Minas Gerais. Data were collected in the Brazilian National Health Information System in 2013. Two annual rates of tooth extraction were calculated. The first was the ratio of the extractions of permanent teeth in relation to the total number of individual dental procedures in primary care. The second was the ratio of the number of extractions of permanent teeth divided by the total population. The statistical analysis of the time series was performed. Results: The two extractions rates behaved erratically during the study period. There was a slight tendency to increase in tooth extraction rate via primary care procedures and slight downward trend in tooth extraction rate in Minas Gerais state population. Conclusions: The slightly tendency in increase or decrease of the tooth extraction rates reveal that they remained constant in this period in the state of Minas Gerais.
