1Department of Preventive Dentistry, College of Stomatology, West China University of Medical Sciences.
Objective:
The aim of this survey was to obtain some information of the prevalence of dental caries in the youth aged 12, 15 and 18 years of Sichuan province.
Methods:
Based on WHO and national oral health survey standards, dental caries prevalence and treatment needs were investigated randomly in selected young individuals of Sichuan province in 1995.
Results:
The prevalent rates of caries of 12-, 15-, and 18-year-old adolescents were 28.47% and 36.40% and 39.54% respectively. The mean DMFT of 12-, 15- and 18-year-old were 0.52, 0.81, and 0.99. There are more pit and fissure caries than smooth caries in the young of 12-year-old than those of 15- and 18-year-old.
Conclusion:
Despite improvement can be seen in adolescents' oral health in Sichuan, there remains a proportion of active untreated decays. Some simple prevention programs are needed to stabilize the caries.
