Spatial distribution of xerostomia and social exclusion index of elderly patients in Piracicaba, SP, Brazil. Arq. Odontol. [online]. 2015, vol.51, n.1, pp. 39-46. ISSN 1516-0939.

Aim: To analyze the spatial distribution pattern of cases of self-reported xerostomia in elderly patients in Piracicaba, SP, Brazil. Methods: Ecological study of the spatial analysis of cases of xerostomia evaluated during the campaign for the prevention and early diagnosis of oral cancer in 2012. This study examined the average annual prevalence, as well as the intensity and significance of agglomerates by means of the global Moran, MoranMap and LISAMap indexes. Results: The prevalence of xerostomia was 17.42%, while the selfreported average annual rate of xerostomia was 3.18 cases/neighborhood and the neighborhoods of Mario Dedini (20.76 cases), Jardim São Jorge (14 28 cases), and Jardim Itapuã (10.61 cases) registered the highest rates. The global Moran's index was -0.317 (p < 0.04), in other words, a significant spatial correlation was observed, which was inverted. A formation of clusters was also observed in the neighborhoods of the South and West regions. Conclusion: In Piracicaba, the spatial distribution pattern of xerostomia, with clustering, indicates where to prioritize efforts in oral health for the elderly.
