Objectives: To estimate the severity of dental caries and the periodontal status of children and adults in Turkey. Basic research design: This cross-sectional study was undertaken between September 2004 and February 2005. The Turkish Statistics Institute (TSI) selected a representative sample using the proportional stratified sampling method. The selected ages/age groups were 5, 12, 15, 35-44 and 65-74. At the end of the study, 7,833 individuals had been reached. Dental students were calibrated and examinations were done according to World Health Organization (WHO) guidelines during home visits. Results: Only 30.2% of the 5-year-old group was caries-free, and the mean dmft was 3.7. Mean DMFT was 1.9 in 12- year-olds, 2.3 in 15-year-olds, 10.8 in 35–44-year-olds, and 25.8 in 65–74-year-olds. In both adolescents and adults, the prevalence of caries was higher among females than in males. In rural areas, the prevalence of caries was high among 5-year-olds, while DMFT was high in the elderly. The prevalence of dental caries was similar for 12- and 15-year-olds in urban and rural areas. Slightly less than half (48.0%) of 65-74 year-olds were edentulous. Healthy periodontal tissue was noted in 56.2% of fifteen-year-olds. In the 35-44 yr-old age group, calculus problems were high (62.6%), and 1.2% had attachment losses of 6mm or greater. Rural subjects had more severe periodontal problems than their urban counterparts. Conclusion: Community-based oral disease prevention programs are needed urgently for the promotion of oral health in Turkey.
