| Research Abstract |
The results in the study of a periodontal disease in Severe Motor Intellectual disabilities (SMID) were as follows. The gingival findings by CPI of SMID turned worse from youth than general population. The most useful factor for distinguishing between suffering from gingival overgrowth and non-gingival overgrowth were "kind of antiepileptic drug" and "oral cleaning condition". The incidence of gingival overgrowth was the highest among those taking phenytoin (PHT). The characteristic of persons suffering from gingiver overgrowth were "taking PHT and not taking valproic acid (VPA)" or 2 taking VPA and not taking PHT"; furthermore those were poor oral cleaning condition. The risk become higher when they were "female" and "in their tens". In periodontal disease - related bacteriological examination for gingival overgrowth cases, P.g., B.f. in severe cases were detected in a significantly high ratio than that of light cases.
In the caries incidence rate of 3-4 years old children, the rate of the children with disabilities with disabilities was significantly higher than that of normal children. The caries incidence rate of the pre-school children were maintained low rate than that of the pre-school normal children by carrying out periodical examination and oral hygiene instruction by dental staff for 3 years.
In analyzing by contact micro-radiography, decalcification depth of primary tooth enamel of normal children was deeper than that of Down syndrome children using the tooth-enamel dissolution liquid.
