The dental care status has been surveyed on the employees of 16 factories in Fukuoka City consisting of 563 males and 621 females ranged in age from 16 to 59 years. The subjects were divided into both sexes and subdivided into age ranges from 16 to 19, 20 to 29, 30 to 39, 40 to 49 and from 50 to 59, and on these groups the caries incidence and the rate of treated cases were observed. The results obtained were summarized as follows. 1. Percent Caries Incidence Percent incidence for the male groups ranged from 63.3 to 93.5, and that for the female groups ranged from 74.8 to 100.0. The incidence was lowest in 16 to 19 years age groups of both sexes, and rose higher with increasing age stages. There was found no appreciable sex difference. 2. Mean Decayed Teeth (DT Number) The mean number of decayed teeth present in the male groups ranged from 1.4 to 1.8, and that in the female groups from 2 2 to 2.9, indicating slightly greater caries incidence found in the female groups. Age difference in this respect was not so significant. 3. Mean Number of Missing Teeth (MT Number) The mean number of missing teeth for the male groups ranged from 0.1 to 5.3, and that for the female groups from 0.2 to 5.4. The number tended to increase with increasing age stages. Thers was no significant difference between sexes. 4. Mean Number of Filled Teeth (FT Number) The mean count of filled teeth for the male groups ranged from 0.9 to 9.2, and for the female groups from 0.7 to 5.2. The number increased with increasing age stages, There was no significant difference between sexes in this respect. 5. Mean Number of DMFT The mean count of decayed, missing, and filled teeth for the male groups ranged from 2.6 to 10.7, and that for the female groups from 3.0 to 12.2, indicating that the latter groups had more DMFT than the former. This number also showed increase with increasing age stages of both sexes. 6. Mean Number of RT (DMFT minus FT) The number for the male groups ranged from 1.7 to 2.7, and for the female from 2.4 to 4.3, indicating the greater number for the latter groups. This number showed slight increase with advancing age stages of subjects. 7. Percent Tooth Number Requiring Treatment The percentage decreasod for the male groups from 65.0 to 13.7, and for the female groups from 78.2 to 34.9, indicating decreasing rates with advancing age stages, and greater percentage for the female groups than for the male groups. 8. The present survey of dental care status revealed that it was worse in the younger generations of both sexes but especially of female sex.
