The extent of incidence of dental diseases in the Taiwan aborigines living as pure race in closed community have been a subject of interest for dental public health. However it has never been reported about Paiwan or Rukai tribes because of the geographical peculiarity. A study on the Paiwan and Rukai tribes was therefore made in July 1979. A total of 233 subjects, 111 males and 122 females, from 9 to 30 in age were studied on their tooth and periodontal diseases and condition of oral hygiene. The result were as follows : 1. The mean number of the erupted permanent teeth was a little higher value, but no significantly difference was showed, in the females than in the males for the ages from 9 to 15. 2. The percentage of persons with one or more DMF teeth was a maximum of 98.11±1.87% in the males and a maximum of 100% in the females for the ages 9 to 15, and showed a decreasing tendency with an increase in age. No significantry difference between males and females was showed for each age group. 3. The mean number of DMF teeth showed a increasing tendency in the males and females with an increase in age and a maximum of 10.35±1.27 in the males and 11.08±0.91 in the females was observed for the ages from 16 to 30. At the ages from 9 to 15, most DMF teeth were decayed teeth (DT) in both males and females. At the ages from 16 to 30, 84% or more of DMF teeth were decayed teeth (DT). 4. The mean number of DMF tooth-surfaces showed a increasing tendency in the males and females with an increase in age and a maximum of 20.10±3.73 in the males and 20.89±2.28 in the females was observed for the ages from 16 to 30. 5. The DMF tooth rate was 26.36±1.48% in the males and 26.75±1.31% in the females at the ages from 9 to 12 and showed a little increasing tendency with an increase in age and a maximum of 35.38±1.98% in the males and 37.86±1.48% in the females was observed for the ages from 16 to 30. 6. The OHI tended to increase in both males and females with an increase in age. A maximum was 5.82±0.31 in the males and 5.01±0.21 in the females at the ages from 16 to 30. The males showed a significantly higher value (p<0.05) than the females at the ages from 16 to 30. 7. The PMA index tended to increase in both males and females with an increase in age. A maximum was 5.60±1.72 in the males and 3.28±0.80 in the females at the ages from 16 to 30. It was higher value in the males than in the females for each age group although no significantry difference was showed. On the basis of the foregoings, the aboriginal popuration examined was characterized by high prevarence of dental caries and poor oral hygiene, lack of awareness of oral health needs and exhibits no evidence of sustained dental hygiene and introduction of progrum of caries prevention in their community.
