Risk indicators for tooth loss in Kiriri Adult Indians: a cross-sectional study.
BACKGROUND
The aim of this cross-sectional study was to evaluate the risk indicators of tooth loss in adult Kiriri Indians from Brazil.


METHODS
A representative sample of 225 Indians (≥ 19 years of age) was assessed. Interviews using a structured written questionnaire were performed to collect data on demographics and socio-economic status, and health-related data. Probing depth, the distance between the cement-enamel junction and the free gingival margin, and decayed, missing or filled teeth were evaluated. Bivariate and logistic models were used to assess associations between tooth loss and age, sex, income, education, diabetic status, smoking habits, dental caries, severe periodontitis, plaque index and previous dental visit.


RESULTS
Eighty per cent of subjects had lost one tooth or more, and 20% had lost eight teeth or more. Mean (± standard deviation) tooth loss was 5.09 (± 5.83) teeth. After adjustment for covariates, loss of one tooth or more was associated with older age [≥ 35 years; odds ratio (OR) = 4.06, 95% confidence interval (95% CI): 1.38-11.94, P = 0.01], severe periodontitis (OR = 3.35, 95% CI: 0.99-11.24, P = 0.05), higher dental caries (OR = 3.24, 95% CI: 1.35-7.78, P = 0.01) and previous dental visit (OR = 23.32, 95% CI: 5.75-94.63, P < 0.001).


CONCLUSIONS
Tooth loss is highly prevalent in Kiriri Indians. Older age, severe periodontitis, higher caries index and previous dental visit were associated with tooth loss. Prevention and treatment programmes, targeting high-risk groups, are required to promote the oral health of the population.
