In this study, we investigated the oral conditions of 77 handicapped children (57 boys and 20 girls) and backgrounds of living in an institution. The results were as follows. Among 73 children having permanent dentition, the percentage of subjects with one or more DMF teeth was 94.52%, while DMFT was 7.45. The percentage of teeth treated for dental caries was 57.35%. GI (Gingival Index) was 1.7, and OHI-S was 3.50. The other features observed were attrition of posterior teeth in 25 subjects and crowding in 39. According to the degree of mental retardation, severely retarded children had a lower percentage of teeth treated for dental caries than moderately and mildly retarded children. Additionally, the severely retarded handicapped children who were long-time institutionalized and taking antispastic drugs, had the higher incidence of gingivitis and poor oral hygiene. This study indicated the necessity of a scheduled and active practice in order to improve oral hygiene status and gingival condition, and raise the percentage of teeth treated for dental caries of severely retarded children in an institution.
在本研究中，我们调查了77名残疾儿童（57名男孩和20名女孩）的口腔状况以及他们在机构中的生活背景。结果如下。在73名恒牙列儿童中，有一颗或多颗DMF牙的受试者百分比为94.52%，而DMFT为7.45。接受龋齿治疗的牙齿百分比为57.35%。牙龈指数（GI）为1.7，简化口腔卫生指数（OHI-S）为3.50。观察到的其他特征包括25名受试者后牙磨损和39名受试者牙列拥挤。根据智力迟钝程度，重度智力迟钝儿童接受龋齿治疗的牙齿百分比低于中度和轻度智力迟钝儿童。此外，长期在机构中生活且服用抗痉挛药物的重度智力迟钝残疾儿童，牙龈炎发病率较高且口腔卫生较差。本研究表明，有必要进行定期且积极的干预措施，以改善口腔卫生状况和牙龈状况，并提高机构中重度智力迟钝儿童接受龋齿治疗的牙齿百分比。
