SB Brasil 2010: uso e necessidade de prótese dentária em idosos

Abstract

A National Oral Health Survey (SB Brasil 2010) was performed in 2010, being representative to the state’s capitals, Federal District and for the five Brazilian Regions. Due to demographic transition marked by the populational ageing that is occurring in Brazil, this study analyzed elders from 65 to 74 years (n= 7,496). The aim of this study was to describe the use and need of prosthesis among Brazilian elders and to assess associated factors. Use and need of dental prosthesis were used as the outcomes, which were determined according to the World Health Organization index. The other explanatory variables included were Brazilian region, gender, skin color; familial income, schooling level, type of dental service used and the self reported need of dental prosthesis. Descriptive, bivariate analyses and multivariate analysis using Poisson regression were performed (P<0.05). The prevalence of use was 78.2% and the need was 68.7%, varying between regions. In the multivariate analysis, a higher use of prosthesis was observed in females [RP 1.19 95% CI (1.10-1.29)], and in those with 57 years of study [RP=1.11 CI95% (1.03-1.19)], and in those attending to private dental services [RP=1.23 CI 95% (1.10-1.38)] compared to public service. Lower use was observed in dark black skinned [RP=0.83 CI 95% (0.74-0.93)] compared to the white ones. The self-reported need of dental prosthesis was a protection factor in relation to the use of dental prosthesis [RP=0.81 IC 95% (0.76-0.87)]. In the multivariate analysis, a lower need of dental prosthesis was observed in females [RP=0.92 CI95% (0.85-1.0] and in those accessing private dental services [RP=0.87 CI 95% (0.77-0.98)]. A higher need was found in those self-reporting dental prosthesis need [RP=1.58 CI95% (1.39-1.79)]. It was observed a high prevalence of dental prosthesis use and the need of dental prosthesis, influenced by regional disparities, socioeconomic and demographic variables use of services and by the own patient opinion. There is a need to increment the oral public health policies in order to reduce the significant demand for dental prosthesis in elderly.
