This systematic review assessed the morphological characteristics of non-carious cervical lesions (NCCL), among clinical and ex-vivo studies assessed by observational and imaging methods.
The search strategy was conducted on four online databases (MEDLINE, Embase, Scopus and Web of Science) and grey literature (Google Scholar and OpenGrey). The study selection was performed by three reviewers from March to September (2023). The eligibility criteria were established according to the PICO strategy and included NCCL, morphological characteristics and clinical and ex-vivo study designs. The data extraction considered general data that identifies the study, evaluation method, parameter to assess the outcome and the main results for each study. The risk of bias was evaluated using Joanna Briggs Institute critical appraisal tool, and a personalized tool.
The search resulted in 252 studies. A total of 14 studies were included. Prevalence of NCCLs ranged from 3.5 %to 77.78 % with a higher presence in premolars. Common characteristics were wear facets, occluded tubules or cracks, occlusal stress, scratch marks, dimples and craters, structure loss, and dentin sclerosis, which appear more often on buccal surface and were generally classified as wedge-shaped, saucer-shaped. Etiological hypothesis was mainly related to multifactorial factors. In most of the studies, the risk of bias was classified as high.
The morphological characteristics of NCCL showed a wide range of descriptions regarding appearance, prevalence, lesion-related measures, and macro and microscopic descriptions.
本系统评价评估了临床和离体研究中观察性和影像学方法评估的非龋性颈壁缺损（NCCL）的形态特征。
搜索策略在四个在线数据库（MEDLINE、Embase、Scopus 和 Web of Science）和灰色文献（Google Scholar 和 OpenGrey）上进行。研究选择由 3 名评审员于 2023 年 3 月至 9 月进行。根据 PICO 策略制定了纳入标准，包括 NCCL、形态特征以及临床和离体研究设计。数据提取考虑了标识研究、评估方法、评估结果的参数以及每项研究的主要结果的一般数据。使用 Joanna Briggs 研究所的批判性评估工具和个性化工具评估偏倚风险。
搜索共产生 252 项研究。共有 14 项研究被纳入。NCCL 的患病率从 3.5%到 77.78%不等，前磨牙的患病率较高。常见特征为磨损面、封闭的小管或裂缝、咬合应力、划痕、凹痕和坑洼、结构丧失和牙本质硬化，这些特征更常见于颊面，通常分类为楔形、碟形。病因假说主要与多因素有关。在大多数研究中，偏倚风险被归类为高。
NCCL 的形态特征在外观、患病率、与病变相关的测量值以及宏观和微观描述方面存在广泛的描述。
