背景:关于牙科学校牙髓治疗后影响牙齿固位的危险因素的研究有限。了解这些因素对于保护牙齿至关重要。这项回顾性研究的目的是评估与经牙髓治疗的牙齿存活相关的患者和牙齿水平的风险因素。
方法:分析了2017年至2020年在宾夕法尼亚大学牙科医学院接受牙髓治疗的患者的电子健康记录。患者水平因素包括年龄,性别,美国麻醉师学会身体状况分类,吸烟史,糖尿病状态,和阿莫西林过敏.牙齿水平因素包括位置,修复的存在,修复前治疗的牙周状况。
结果:这项研究的结果表明,与牙齿保留显着相关的患者水平因素包括年龄,性别,美国麻醉师学会身体分类状况,和阿莫西林过敏.牙齿水平因素,如核心堆积,全覆盖皇冠,健康的牙周组织,结垢和根系平整也与较高的存活率有关。下颌前磨牙的存活率高于下颌磨牙。
结论:这项调查显示,最初的根管治疗后,经牙髓治疗的牙齿的保留率为96.2%,92.4%用于非手术再治疗,手术再治疗占97.8%。
结论:牙髓治疗的牙齿固位与健康的牙周组织有关,牙齿结构,齿位置,牙齿修复,和病人的整体健康状况。
Studies on risk factors affecting tooth retention after endodontic treatment in dental school settings are limited. Understanding these factors is crucial for preserving teeth. The aim of this retrospective study was to evaluate patient- and tooth-level risk factors associated with the survival of endodontically treated teeth.
Electronic health records of patients who underwent endodontic treatment at the School of Dental Medicine at the University of Pennsylvania from 2017 through 2020 were analyzed. Patient-level factors included age, sex, American Society of Anesthesiologists Physical Status Classification, smoking history, diabetes status, and amoxicillin allergy. Tooth-level factors included position, presence of restorations, and periodontal conditions with preprosthetic treatments.
The results of this study indicate that the patient-level factors significantly associated with tooth retention included age, sex, American Society of Anesthesiologists Physical Classification Status, and amoxicillin allergy. Tooth-level factors such as core buildup, full-coverage crown, healthy periodontium, and scaling and root planing were also associated with higher survival rates. Mandibular premolars had higher survival rates than mandibular molars.
This investigation revealed that the tooth retention rate of endodontically treated teeth was 96.2% after initial root canal treatment, 92.4% for nonsurgical re-treatment, and 97.8% for surgical re-treatment.
The tooth retention of the endodontic treatment was associated with healthy periodontium, tooth structure, tooth position, tooth restoration, and the patient\'s overall health.
