Generally, it is believed that occurences of carious teeth and alveolar pyorrhea are high in mental patients. One of the present authors, Tamai, studied the teeth of 276 male schizophrenic cases, in 1942, at Musashi National Sanatorium. Ten years later, in 1953, the other author, Kimoto, studied the teeth of the 14 cases out of the above 276 cases, and compared the results of them and found interesting findings. Incidentally, the comparison was performed in the imprinted models of teeth, and case-records, as of 1942 and 1953. Results are tabulated as follows:
1) Total number of teeth: in 1942, 446 in 1953, 369
2) Total number of carious teeth: in 1942, 64 in 1953, 63
3) Loss of carious teeth: 34 Loss of teeth by extraction: 4 Loss of teeth by fracture: 2
4) Wisdom teeth which erupted in late twenties (26, 29, 30 years of age, respectively) in 3 cases
5) Abrasion of teeth: 1 case.
6) Two teeth separated from each, other: 3 cases
7) Space between teeth became closer: 2 cases
8) Loss of metal crown: 3 cases
9) Materials of amalgam fillings with no changes during 10 years: 3 cases
10) Total number of newly developed carious teeth: 32
Total number of old carious teeth: 16
