To determine the prevalence and correlates of tooth loss in Sri Lankan adults.
A descriptive cross sectional study.
Colombo district of Sri Lanka.
Adults aged 20 years and above.
Data were collected by means of an interviewer administered questionnaire and an oral examination.
The overall prevalence of tooth loss was 81.6% while 1.9% of the sample was edentulous. The prevalence rates of tooth loss in the 20-39, 40-59 and ≥ 60-year-old were 71%, 93% and 96%, respectively, while 0%, 1.5% and 11.4% were edentulous in the three groups. Age (OR = 1.10; 95% CI = 1.08-1.11), having received 11 or more years of education (OR = 0.38; 95% CI = 0.15-0.97), use of fluoride toothpaste (OR = 0.44; 95% CI = 0.30-0.66), brushing frequency (OR = 0.62; 95% CI = 0.43-0.89) and use of dental services (OR = 2.08; 95% CI = 1.12-3.84) were significantly associated with having more than 12 missing teeth.
The overall prevalence of tooth loss is high among Sri Lankan adults.
