Repair increases the longevity of restorations and is well-accepted by patients. In this study, the authors assessed the acceptance of dental restoration repair by dentists and determined the main variables of repair versus replacement of defective restorations.
A 15-item questionnaire was developed and distributed electronically to the American Dental Association Clinical Evaluators panel members (n = 785) during a 2-week period in 2019. Descriptive, bivariate, and multivariable analyses were conducted.
Of the 387 respondents, 83.7% stated that they repair defective restorations, and 16% stated that they always replace them. Reasons to forego a restoration repair among dentists who perform repairs included defect size and carious lesion extension (42%) and negative personal experience or lack of success (37.9%). However, the latter was considerably higher for dentists who do not perform repairs (60.7%). The most commonly cited patient-related reason and tooth condition to repair restorations were limited patient finances (67%) and noncarious marginal defects (86%), respectively. Neither sex nor age group was significantly associated with the practice of restoration repair (P = .925 and P = .369, respectively). However, sole proprietors were more likely to perform repairs than those in an employee, associate, or contractor practice setting (P = .008). The most significant reason to forego restoration was negative experience or lack of success (P = .002).
Restoration repair is considered a treatment option for managing defective restorations. Negative personal experience or lack of success and practice setting influenced the dentists' decision to repair or replace a defective restoration.
Understanding dentists' clinical challenges and practice environment is necessary when advocating for this approach.
修复可以延长修复体的使用寿命，并且深受患者的认可。本研究评估了牙医对牙体修复体修复的接受程度，并确定了修复与更换有缺陷的修复体的主要变量。
在 2019 年的两周内，通过电子方式向美国牙科协会临床评估员小组（n=785）成员分发了一份包含 15 个问题的问卷。进行了描述性、双变量和多变量分析。
在 387 名答复者中，83.7%表示他们会修复有缺陷的修复体，而 16%表示他们总是更换它们。对于进行修复的牙医来说，放弃修复的原因包括缺损大小和龋坏延伸（42%）以及个人负面经历或缺乏成功（37.9%）。然而，对于不进行修复的牙医，后者的比例要高得多（60.7%）。最常被引用的与患者相关的修复原因和牙齿状况分别是患者经济有限（67%）和非龋性边缘缺损（86%）。性别和年龄组与修复体修复的实践均无显著相关性（P=0.925 和 P=0.369）。然而，独资经营者比员工、合伙人或承包商更有可能进行修复（P=0.008）。放弃修复的最主要原因是个人负面经历或缺乏成功（P=0.002）。
修复被认为是处理有缺陷修复体的一种治疗选择。个人负面经历或缺乏成功和实践环境影响了牙医修复或更换有缺陷修复体的决策。
了解牙医的临床挑战和实践环境对于倡导这种方法是必要的。
