Prevalence and Factors Associated with Tooth Loss in Urban Quilombola Adults (18–64 Years Old): A Cross-Section Study

The objective was to analyze the prevalence and associated factors of tooth loss in an urban adult Quilombola population in the expanded age range (18–64 years). This cross-sectional study was conducted with a non-probabilistic sample of adults from the Quilombola population of Barro Preto, Jequié, Bahia, Brazil. Household data collection included an oral examination and questionnaire. The study outcome was the prevalence of tooth loss: yes (one or more missing teeth) or no. The Poisson regression model used an adapted theoretical conceptual model of tooth loss. A total of 238 adults were included. The prevalence of tooth loss was 74.4%, with an average of 9.28 (±10.03) teeth lost per adult. In the final adjusted model, Quilombola adults of advanced age, between 35 and 44 years old (PR = 1.22; 95%CI:1.12–1.33, p < 0.001) or 45 and 64 years old (PR = 1.23; 95%CI:1.12–1.33, p < 0.001), in a stable union (PR = 1.05; 95%CI:1.01–1.11, p = 0.048) and who sought dental services motivated by need (PR = 1.22; 95%CI:1.12–1.32, p < 0.001) or pain (PR = 1.22; 95%CI:1.13–1.32, p < 0.001) presented a higher prevalence of tooth loss. It was concluded that there was a high prevalence of tooth loss, and that demographic factors, such as age and marital status, behavior, and reason for consultation, were associated with tooth loss in the adult Quilombola population.
