This retrospective study evaluated the factors influencing the clinical failure of noncarious cervical lesion (NCCL) restorations.
Patients were routinely treated by undergraduate or postgraduate students and randomly received a clinical recall evaluation. A retrospective study was performed with two experienced calibrated examiners to evaluate NCCL restorations, including the critical parameters of retention, caries, marginal discoloration, and marginal integrity. The factors related to the restoration included gender, age, arch site, tooth position, the presence of occlusal wear facets, caries risk, operator, adhesive strategy, and composite. The clinical failure comparison between the parameters and factors was performed using the binary logistic regression analysis.
A total of 460 cervical restorations from 96 patients were evaluated. The adhesive strategy and the presence of occlusal wear facets were the most important factors influencing the parameter failure. Therefore, the highest failure was marginal integrity, in which the gingival marginal integrity failure was 50.7%, and the occlusal marginal integrity failure was 42.4%.
The main factors influencing clinical failure for partial loss, marginal discoloration, and marginal integrity were the adhesive strategy and the presence of occlusal wear facets. Therefore, marginal integrity was the most frequent failure parameter.
本回顾性研究评估了影响非龋性颈部病变（NCCL）修复体临床失败的因素。
患者由本科生或研究生进行常规治疗，并随机接受临床回访评估。由两名经验丰富且经过校准的检查者进行回顾性研究，以评估NCCL修复体，包括固位、龋病、边缘变色和边缘完整性等关键参数。与修复相关的因素包括性别、年龄、牙弓部位、牙齿位置、咬合磨损面的存在、龋病风险、操作者、粘结策略和复合材料。使用二元逻辑回归分析对参数和因素之间的临床失败情况进行比较。
共评估了96例患者的460个颈部修复体。粘结策略和咬合磨损面的存在是影响参数失败的最重要因素。因此，失败率最高的是边缘完整性，其中牙龈边缘完整性失败率为50.7%，咬合边缘完整性失败率为42.4%。
影响部分丧失、边缘变色和边缘完整性临床失败的主要因素是粘结策略和咬合磨损面的存在。因此，边缘完整性是最常见的失败参数。
