RESULTS
The results showed that XDMFT in this group was 0.95, permanent caries prevalence rate was 39.78%, lower than that of the same age children in other 11 provinces in Mainland(P < 0.001). The proportion of DMFT was 86.78%(D), 4.30% (M), 8.92% (F), respectively. The caries number that needed dental care were 1842 teeth(0.78 teeth per person).
