RESUMO

The aim of this study was to assess the prevalence, extent and severity of clinical attachment loss (CAL); and to investigate the associations between demographic, socioeconomic and behavioral risk indicators with CAL in an untreated isolated population in Brazil. METHODS: All subjects aged 12 years forward were selected by a census. They were submitted to a full-mouth clinical examination of six sites per tooth and were interviewed using a structured written questionnaire. RESULTS: Among the 214 subjects who were interviewed and clinical examined, CAL >= 5mm was observed in 8%, 37%, 70%, 83%, and 100% of the dentate subjects, depending on age; while the age dependent prevalence of CAL >= 7mm was 5%, 8% 20%, 67% and 83%, respectively. Multivariate analysis identified amount of plaque (OR=2.8), thresholds of supragingival calculus (OR=2.9-10.6), age (OR=11.4) and smoking (OR=2.4) as risk indicators for CAL >= 5mm, and smoking (OR=8.2) for CAL >= 7mm. CONCLUSION: The results demonstrate that CAL is highly prevalent in this isolated population. The high prevalence of CAL in young age groups and the observation of traditional risk indicators for CAL in this population suggest microbiological factors or host susceptibility to be key factors explaining the high levels of CAL found in this population.
