Abstract

Objectives: The purpose of this study was to examine the relationships between patient characteristics and reasons for extraction of permanent teeth. Methods: 5,131 dentists were selected from the list of the membership directory of the Japan Dental Association by systematic random selection. The dentists were asked to record the reason for each extraction of permanent teeth during a period from February 1 to 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. We used cross tabulation and multiple logistic regression analysis to estimate the relationships between patient characteristics and reasons for tooth extraction. Results: 2,001 dentists (response rate of 39.0%) returned the forms, and complete information on 7,333 patients was obtained. A total of 3,196 (43.6%) patients underwent tooth extraction due to caries and its sequela, and 2,721 (37.1%) patients underwent tooth extraction due to periodontal disease. Multiple logistic regression analysis showed that denture wearers were more likely to undergo tooth extraction due to periodontal disease in all age groups (p
