In 1980, prevalence of dental caries and gingivitis, and oral hygiene condition were surveyed in 194 Yami children (107 boys and 87 girls) between 10 and 15 years of age. The mean number of DMF teeth was 1.43 (boys) and 1.67 (girls) in the 10-to 11-year-olds. The number increased with age and reached 2.85 (boys) and 3.55 (girls) in the 14- to 15-year-olds. However, the DMF score in Yami children was lower than that in Japanese children. The Yami children had extremely high OHI values (2.86-4.60), and the fact revealed that a half of every tooth surface was covered with dental plaque. PMA Index of Yami children was 3.67 (12- to 13-year-old girls) to 10.90 (14- to 15-year-old boys). These findings indicate that the dental plaque in the Yami children may be injurious to their gingival tissue but low in caries activity to their teeth.
