A total of 1422 permanent teeth were extracted in our clinic during period from January to June, 1996. We surveyed the reason for these extracted teeth and obtained the following results. 1. Caries were the most frequent cause for extraction (61.5%), followed by periodontal diseases (26.0%) , eruption problems (11.1%) and others(1.4%). 2. The number of extraction began to rise steeply in 40 s, and reached the peak during the 60 s. 3. In the age group over 40 years old, extraction due to periodontal diseases increased, but caries was the principal reason for extraction in the age groups. 4. In the lower incisors, periodontal diseases were the main reason for extraction. 5. The highest number of extracted teeth was the third molar, and approximately 70% of it were removed under 30 years of age.
