目的：拔牙的常见原因包括牙周病、龋齿和牙根折断。本研究的目的是调查修复治疗后牙齿脱落的关系，特别是牙根折断的发生率，这种情况经常发生且难以预防。 方法：从首次就诊大阪大学牙科医院 3 年后连续选择的患者病历中收集数据。收集的数据包括 (1) 年龄和性别，(2) 初次就诊时的牙齿数量和拔牙数量，(3) 拔牙原因，(4) 有或没有桩修复，以及 (5) 可摘局部义齿 (RPD) 的基台。对拔牙原因、是否用桩修复、是否扣紧牙齿进行了卡方检验。使用逻辑回归分析来确定牙根骨折与患者数据的关联。结果：本研究包括 101 名患者（296 颗拔除的牙齿）。拔牙的原因包括牙周病（64.6%）、龋齿（25.3%）和牙根折断（10.1%）。女性的牙根折断百分比显着高于男性，带桩修复体的牙齿显着高于无桩修复体，RPD 基台的牙根折断百分比显着高于非基台牙齿。 Logistic回归显示，牙根折断与性别和基牙显着相关。结论：修复后拔牙最常见的原因是牙周病和龋齿，其次是牙根折断。牙根骨折与 RPD 的性别和基牙显着相关。 (C) 2010 年日本修复学会。由爱尔兰爱思唯尔出版。版权所有。
Purpose: Common reasons for tooth extractions include periodontal disease, dental caries and root fracture. The purpose of this study was to investigate the association of tooth loss after prosthetic treatment, particularly incidences due to root fracture, which occur frequently and are difficult to prevent.Methods: Data were collected from consecutively selected medical records of patients taken over 3 years after their initial visit to Osaka University Dental Hospital. Collected data included (1) age and gender, (2) number of teeth at the initial visit and number of extracted teeth, (3) reasons for extraction, (4) restored with or without a post and (5) abutment of removable partial dentures (RPDs). A Chi-squared test was applied among the reasons for extraction, whether the tooth was restored with a post or not and clasped or not. A logistic regression analysis was used to determine the associations of root fracture with the patient data.Results: This study included 101 patients (296 extracted teeth). The reasons for extraction included periodontal disease (64.6%), caries (25.3%) and root fracture (10.1%). The percentage of root fracture was significantly higher for female than male, for restored teeth with posts than without posts and for abutment of RPDs than for non-abutment teeth. Logistic regressions showed that root fractures were significantly associated with gender and abutments.Conclusion: The most frequently stated reasons for tooth extraction after prosthetic treatment were periodontal disease and dental caries, followed by root fracture. Root fractures were significantly associated with gender and abutment teeth of RPDs. (C) 2010 Japan Prosthodontic Society. Published by Elsevier Ireland. All rights reserved.
