MOREIRA, Rafael da Silveira; NICO, Lucélia Silva and TOMITA, Nilce Emy. Spatial risk and factors associated with edentulism among elderly persons in Southeast Brazil. Cad. Saúde Pública [online]. 2011, vol.27, n.10, pp. 2041-2054. ISSN 1678-4464. http://dx.doi.org/10.1590/S0102-311X2011001000017.
This study aimed to identify factors associated with edentulism and spatial risk of tooth loss in the elderly. A cross-sectional study was conducted using a random sample (n = 372) of individuals 60 years and older in Botucatu, São Paulo State, Southeast Brazil, in 2005. Crude and adjusted prevalence ratios were estimated by Poisson regression with robust variance. Spatial analysis was performed using Kernel intensity estimation. Prevalence of edentulism was 63.17%. Socio-demographic factors associated with edentulism according to multiple regression were low schooling, household crowding, not owning a car, older age, lack of a regular dentist, and the last dental visit three previously or longer. Spatial analysis showed greater risk of edentulism in the peripheral areas of the city. The results help understand the high prevalence of tooth loss among the elderly, thus providing essential information for planning oral health interventions.
