摘　　要：目的了解成都市孤残儿童的患龋状况及相关性,探讨其适宜的防治措施。方法调查成都市5个特殊学校6～12岁孤残儿童共280名,以龋失补牙指数(DMFT/dmft)评估其患龋状况,分析患龋的相关因素,以配合度和残疾类型评估其防治工作的难度程度。结果所有调查对象的患龋率和龋均分别为59.6%和2.16±2.63,其中乳牙患龋率和龋均各为46.4%和1.70±2.50,恒牙患龋率和龋均各为23.9%和0.47±1.05,乳牙和恒牙的龋齿充填率各为2.1%和7.6%。各患龋率及龋均在男性和女性间的差异均无统计学意义(P>0.05)。第二乳磨牙龋坏和第一乳磨牙龋坏呈较强相关关系(P<0.001,r=0.593)。配合度属于中高难度者占18.21%。结论孤残儿童的患龋率较高;第二乳磨牙龋坏和第一乳磨牙龋坏呈较强相关关系,可作为临床及预防工作中的龋风险评估指标;部分孤残儿童的防治工作难度较大。Objective To investigate caries status of primary and permanent teeth among 6-12-year-old orphans and disabled children in Chengdu and to discuss the appropriate measures of prevention and treatment. Methods A sample of 280 6-12-year-old orphans and disabled children, were selected from 5 special schools in Chengdu. The index of decayed missing filled tooth （DMFT/dmft） was recorded to assess the caries status and analysis with carious related factors. Degree of compliance （DC） and types of disability were used to measure difficulty of preventive and treatment measures. Results The total prevalence rate of dental caries was 59.6%, the total mean DMFT/dmft was 2.16±2.63, caries rate with deciduous teeth was 46.4%, the deciduous teeth mean DMFT/dmft was 1.70±2.50, caries rate with permanent teeth was 23.9%, the permanent teeth mean DMFF/dmft was 0.47±＋1.05. Caries filling ratio of deciduous teeth was 2.1%, caries filling ratio of permanent teeth was 7.6%. The prevalence rate and mean DMlTdmft between males and females showed no significant 60〉0.05）. There was a strong correlation between first and second deciduous molar（P〈0.001, r=0.593）. And DC of 18.21% children was medium and severe. Conclusion This study revealed a high level of dental caries status of 6-12-year-old orphans and disabled children. There was a strong correlation between first and second deciduous molar, it may be used to assess caries risk in clinic and prevention. And it could be very difficult to prevent and treat in some children.
