ORAL INVESTIGATION OF CHILDREN IN AFEEBLEMINDEDNESS ESTABLISHMENT OF OSAKA

I investigated the mouth of the 70 feeblemindedness-girls and boys who were 5-19 years old and I.Q. 16-74.They were not up to census age in physical strength and mental activity, I found the many odontoloxia, abnomal bites and malformed teeth in the mouth, but it is 70.58 % in their teeth caries morbidity, this percent is more reduced than the other reports', and I found just only 2.02% handicap between the caries morbidity of the general cildren and their.I think, it has its source in the their food and an effect of the oral cleaning guidance over a 6-years period.About the relation between intelligence quotient and tooth caries, I think, the reason why the inferion have many caries is due to their dull sense of the oral hygiene rather than inheritance or constitution, and if we gave a good lead to them, they would have a keen sense of oral, even if they were the inferior, and their caries morbidity will go down as a general health children.
