Saúde bucal dos Yanomami da região de Xitei e Ketaa Roraima - Brasil

Abstract

This paper results from the data analysis of the oral health epidemiological survey of the Yanomami indigenous community based on Xitei indigenous area and Ketaa indigenous sub-area. It was followed the SB Brasil 2003 Project and WHO methodology rules. The variable observed were: Decay, Missed and Filled Tooth index (DMF-T); treatment necessity; use and necessity of prosthesis; community periodontal index (CPI); periodontal attachment loss index (PALI). In this study, 823 indigenous of a total of 1220 resident indigenous in this region, being 50.6% of masculine sex and 49.4% of the feminine sex, had been examined. The age of this sample approaches to the total population above of 2 years. The tooth attacked by caries average in the examined population was 0,23 ± 0,60; 0,33± 0,75; 1,43± 1,39 in age bands 12, 15-19 and more than 60 years, respectively. The values found for index DMF-T had been very low, near to zero in all the age bands except for people above of 50 years (DMF-T = 1.21). It was observed that 82.3% of the total of the sample were presented free of caries. Differences between men and women in the prevalence of caries had gotten no statistical significance. The results found for the periodontal condition had demonstrated a bigger prevalence of bleed, calculus and 4-5 mm pockets when compared to the data in the same age bands of the Brazilian population and North Brazilian Region population. Rare dental losses had been registered between the investigated population and no patient was identified who needed prótese removable or total prosthesis. The condition of very low prevalence of caries found between the Yanomami of Xitei makes to assume that the distance of the places of food commercialization allies to the strategy of systematization in the relations of exchange between indigenous and non-indigenous in the region, that do not include strange item to the traditional feeding, probably have influenced the maintenance of a good condition of oral health
