Abstract
Background
Knowledge about factors associated with tooth loss contributes to the planning of preventive actions carried out by Oral Health Teams (OHT).
Objective
To evaluate the proportion of dental extraction indicator in the cities of the state of São Paulo, Brazil, and its relationship with socioeconomic indicators and coverage of the OHT.
Method
Ecological study using secondary data from 654 municipalities in the state of São Paulo conducted in 2012. The dependent variable was the percentage of dental extraction measured by the proportion of this indicator in relation to individual procedures performed by the OHT provided by the Primary Health Care (PHC) Information System. The population coverage by the OHT, the per capita Gross Domestic Product (GDP), the Human Development Index (HDI), and the São Paulo Social Responsibility Index (IPRS) of the municipalities were evaluated as independent variables. Generalized linear models, formulated by the Wald test p-value, Corrected Akaike Information Criterion (AICc), and degree of freedom, were applied.
Results
Higher proportions of dental extraction were found in the municipalities with lower coverage by OHT (p<0.0001), lower HDI value (p<0.0001), and higher IPRS value (p=0. 0018).
Conclusion
Low coverage by OHT and socioeconomic inequalities contribute to increased proportion of dental extractions in the state of São Paulo.
