唇腭裂患者龋齿流行情况调查

Prevalence of Caries in Children with Cleft Lip and/or Palate

目的:评估唇腭裂患者的龋齿流行情况。方法:使用龋失补(DMF/dmf)指数对6～12岁组、13～18岁组不同唇腭裂类型的286名患者的龋坏进行记录。结果:唇腭裂患者恒牙龋流行随年龄增长而增加(P<0.05)。6～12岁组中51%未患龋,龋均(DMFT)为1.77。13～18岁组中,4%未患龋,DMFT值为6.96。不同类型的唇腭裂患者的DMFT/dmft无统计学意义。结论:年龄是影响唇腭裂患者恒牙龋齿流行的主要因素,而类型并不是主要因素。

rAbstract7 Objective： To assess the prevalence of dental caries in children with oral clefts. Methods： 286 children aged 6-to 12 and 13- to 18-years old with different cleft types （CL, CLP, CP） were investigated, using the standard dental indices dmf（t） and DMF（T）. Results： In permanent teeth, caries prevalence increased with increas- ing age. 51% of patients at 6-to 12-years old and 4 % of patients at 13-to 18-years old were caries free. The mean DMFT for 6-to 12-years old group was 1.77 and the mean DMFT for 13-to 18-years old group was 6. 96. In permanent teeth and primary teeth, the caries experiences within different cleft types were not statistically significant different between 6-to 12-years old group and 13-to 18-years old group. Conclusion： The age was a major factor, but the cleft types seem to be not an important factor for influencing the prevalence of caries.
