| Summary: | Objective To explore the caries status of permanent teeth among 12⁃15⁃year⁃old population in Guang⁃
dong Province, and to provide information support for oral health care. Methods A cross⁃sectional survey was carried
out among 7 680 urban and rural residents in Guangdong Province. Subjects were from four different age groups (aged
12, 13, 14 and 15), with 1 920 people in each group. An equal⁃sized stratified multistage randomly sampling was used,
with a gender ratio of half to half in each group. According to the criteria of clinical dentition examination of the fourth
national oral health survey, the crown caries of permanent teeth in the whole mouth were recorded using CPI probe. And
then the prevalence, the mean DMFT (decayed⁃missing⁃filled tooth), the filled rate were calculated. Results The preva⁃
lence of crown caries in the groups of aged 12, aged 13, aged 14, aged 15 were 43.07%, 45.31%, 49.69%, 52.86%, re⁃
spectively. The mean DMFTs were 1.06, 1.13, 1.38, 1.59, respectively. The filled rates were 20.19%, 21.50%, 22.86%,
21.33%, respectively. The prevalence and the mean DMFT increased with age (P < 0.001), and both were higher than
that in 2005. There were significant differences in the prevalence and the mean DMFT between urban and rural areas and between male and female (P < 0.001). Conclusion According to the criteria of the mean DMFT in 12⁃year ⁃old
population of WHO, the severity of caries of permanent teeth in Guangdong was regarded as "very low". But the severity
was higher than that in 2005, and the filled rate was low. |
