Objective:
To survey the prevalence of dental caries and the needs for dental treatment in Anhui province.
Methods:
The survey of prevalence of dental caries in group aged 12 and 15 years in Anhui province was conducted using the non-proportional, stratified, cluster sampling method.
Results:
DMFT in 12-year and 15-year group was 0.58 and 0.95 respectively, and permanent tooth caries prevalence rate was 30.78% and 39.78% respectively, lower than that of same age of other 11 provinces in mainland China (P < 0.01). The constituent ratio of DMFT was 90.51% (D), 2.48% (M), 7.01% (F) in 12-year group and 86.78% (D), 4.30% (M), 8.92% (F) in 15-year group.
Conclusions:
When we controlled dental caries in 19.98% 12-years crowd and 22.8% 15-years crowd of Anhui province, we will had controlled the occurrence of 80% caries too in group aged 12 and 15 years.
