This systematic review and meta-analysis aimed to estimate the global prevalence of gingival recession (GR) in the general population.
Population-based observational studies reporting the prevalence of GR and published from 1991 to 2021 were identified from five electronic databases and manual searches. Risk of bias was assessed using the Joanna Briggs Institute's Critical Appraisal Checklist for Prevalence Studies. The pooled prevalence of GR was calculated by using a random-effect model. Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach was used to summarize the overall certainty of evidence.
A total of 15 studies involving 37,460 participants were included. The overall pooled prevalence was 78.16% at the minimal reported threshold values and 84.92% at ≥1 mm "cut-off" with high heterogeneity among studies. A separate analysis for the buccal GR revealed a pooled prevalence of 75.42%. The risk of bias was found to be high for 10 and low for 5 studies. The overall certainty of the evidence was assessed to be very low.
More than two-thirds of the population worldwide was found to be affected by GR. Studies with standard case definition and less heterogeneity are required to accurately estimate the prevalence of GR.
本系统评价和荟萃分析旨在估计一般人群中牙龈退缩（GR）的全球患病率。
从五个电子数据库和手动搜索中确定了 1991 年至 2021 年期间发表的报告 GR 患病率的基于人群的观察性研究。使用 Joanna Briggs 研究所的流行研究批判性评估清单评估偏倚风险。使用随机效应模型计算 GR 的汇总患病率。使用推荐评估、制定与评价分级（GRADE）方法总结证据的总体确定性。
共纳入 15 项研究，涉及 37460 名参与者。在最小报告阈值值下，总体汇总患病率为 78.16%，在≥1mm“截止”值下为 84.92%，研究之间存在高度异质性。对颊侧 GR 的单独分析显示，汇总患病率为 75.42%。发现 10 项研究的偏倚风险较高，5 项研究的偏倚风险较低。证据的总体确定性评估为极低。
全世界超过三分之二的人口被发现患有 GR。需要有标准病例定义和较少异质性的研究来准确估计 GR 的患病率。
