Results: The prevalence of dental caries and mean Decayed, Missed, Filled permanent teeth (DMFt)/ decayed, missed, filled primary teeth (dmft) were 82.9% and 5.9±4.6 among 5 year olds, 80.9% and 2.5±2.2 among 12 year olds, 97.8% and 9.5±5.2 among 35-44 year olds, 99.1% and 19.9±8.1 among 65-74 year olds (p<0.001). The prevalence of gingivitis was 4.6% , 21.2% , 36.3% , 11.5% and of calculus 0.5% , 7.1% , 53.1%, 24.2% , respectively above groups. The status of intervention urgency was 16.4%, 21.4% , 43.6% , 37.3% in the prompt treatment and 5.9%, 4.2% , 7.0% , 0.7% in immediate treatment recommended.
