背景：日本还没有关于恒牙拔除原因的全国性研究。本次调查的目的是确定在日本的恒牙拔除的原因。方法：从2004年日本牙科协会会员名录中系统选择5001名牙医。被选中的牙医被要求记录在2005年2月1日至7日的一周内每次拔除恒牙的原因。拔牙原因分为5组：龋齿、龋齿或牙髓病导致的牙齿断裂、牙周病、牙周病和其他原因。结果：共有2,001名牙医（回答率为39.1%）返回了问卷，获得了7,499名患者的9,115颗拔牙的信息。结果表明，龋病及其后遗症（分别占43.3%、32.7%和10.6%）和牙周病（41.8%）是导致拔牙的主要原因。由于龋齿或骨折提取常见于所有年龄组超过15岁，而牙周病是占主导地位的组超过45岁的ages.CONCLUSIONS：大多数的恒牙是由于龋齿及其后遗症和牙周病提取。需要预防和护理所有年龄组的龋齿和中年以上年龄组的牙周病。
BACKGROUND: There has been no nationwide study in Japan on reasons for extraction of permanent teeth. This survey was aimed to determine the reasons for extraction of permanent teeth in Japan.METHODS: Five thousand, one hudred and thirty-one dentists were selected by systematic selection from the 2004 membership directory of the Japan Dental Association. The dentists selected were asked to record the reason for each extraction of permanent teeth during a period of one week from February 1 through 7, 2005. Reasons for tooth extraction were assigned to five groups: caries, fracture of teeth weakened by caries or endodontics, periodontal diseases, orthodontics, and other reasons.RESULTS: A total of 2,001 dentists (response rate of 39.1%) returned the questionnaires, and information on 9,115 extracted teeth from 7,499 patients was obtained. The results showed that caries and its sequela (totally 43.3%, 32.7% and 10.6%, respectively) and periodontal disease (41.8%) were the main reasons for teeth extraction. Extraction due to caries or fracture was commonly observed in all age groups over 15 years of age, whereas periodontal disease was predominant in the groups over 45 years of age.CONCLUSIONS: Most of the permanent teeth were extracted due to caries and its sequela and periodontal disease. Prevention and care for dental caries for all age groups and periodontal disease for over middle age groups are required.
