抄録

Significance of changes in the teeth especially Hutchinson and Fournier teeth among student of schools for the blind and deaf was reported from our Department about 10 years ago. In order to assess the recent situation, 124 students were examined in a school for the blind concerning the intraoral state from an odontological point of view.
Abnormalities in the development and morphology of the teeth, degree of carious state, pyorrhea, state of the cleaning of the oral cavity, presence of deposition around the teeth, and relationship with diseases of the eye were investigated. No difference was found between students in the school for the blind and other healthy subjects concerning the degree of carious state, alveolar pyorrhea, state of the cleaning of the oral cavity, and deposition around the teeth. In 4 students Hutchinson and Fournier teeth were noted simultaneously, while Hutchinson teeth alone were noted in 1 and Fournier teeth alone were seen in 8. Among those, congenital complete or almost complete blindness was seen in 8 and acquired complete or almost complete blindness was seen in 5, indicating a pronounced decrease as compared with the result of 10 years ago.
