To determine the prevalence of dental caries in children with cleft lip and Palate.
A cross-sectional study was undertaken in 380 children with cleft lip and Palate and 339 children without cleft. Dental caries were measured with decayed-missing-filed-teeth index (DMFT/dmft) and the decayed-missing-filed-surface index (DMFS/dmfs). A questionnaire survey about the socio-economic conditions and lifestyles of the children's families was undertaken in the parents of the children.
(1) The children with cleft Palates had a higher prevalence of caries and greater DMFT(S) and dmft(s) scores than the children without cleft (P < 0.05), except for those of 3 to 5 years old. (2) For the children of 3 to 5 years old, those with cleft lip and palate had significantly more caries than those with only a cleft lip or a cleft lip and alveolus (P < 0.05). The children who had surgical repairs had lower dmft(s) than those who had not (P < 0.05).
(2) Chinese children with oral cleft have more dental caries than the children without cleft. (2) Children with cleft lip and palate have higher levels of dental caries than those with cleft lip alone. The children who had surgical repairs have less dental caries.
确定唇腭裂患儿的龋齿患病率。
对380例唇腭裂患儿和339例非唇腭裂患儿进行了一项横断面研究。用龋失补牙指数（DMFT/dmft）和龋失补牙面指数（DMFS/dmfs）来测量龋齿情况。对患儿家长进行了关于其家庭社会经济状况和生活方式的问卷调查。
（1）除3至5岁儿童外，腭裂患儿的龋齿患病率更高，DMFT（S）和dmft（s）得分也高于非腭裂患儿（P<0.05）。（2）对于3至5岁的儿童，唇腭裂患儿的龋齿明显多于单纯唇裂或唇裂合并牙槽突裂患儿（P<0.05）。接受手术修复的患儿dmft（s）低于未接受手术修复的患儿（P<0.05）。
（1）中国唇腭裂患儿的龋齿比非唇腭裂患儿多。（2）唇腭裂患儿的龋齿水平高于单纯唇裂患儿。接受手术修复的患儿龋齿较少。
