To evaluate the association and level of evidence between socioeconomic status (SES) and tooth wear (TW) in children, adolescents, and adults.
Eligibility criteria comprised population-based observational studies assessing the association between SES and TW in permanent dentition of adolescents and adults. Interventional and descriptive studies or those without an internal comparison between exposed and nonexposed groups were excluded. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were applied where applicable. Risk of bias (RoB) was assessed using the Newcastle-Ottawa scale. Meta-analyses were conducted to estimate the pooled effect measures. Q-statistic, Istatistic, subgroup and sensitivity analyses assessed study heterogeneity.
PubMed/Medline, Embase, Scopus, Web of Science, LILACS, SciELO, Cochrane Library, and Google Scholar databases were searched for articles published in English between 1st January 1980 and 31st March 2021.
Sixty-five studies were included, involving 63,893 participants in over 30 countries. A positive association was found between TW and education (OR=1.25 [0.96; 1.62]), family income (OR=1.18 [0.91; 1.53]), and private school (OR= 1.24 [0.90; 1.72]) among adolescents. Higher educated adults had a lower risk for TW (OR=0.70 [0.52; 0.93]). Most included studies had a moderate RoB. Limitations relating to population representation and assessment methodologies were identified in the included studies.
SES was associated with TW with its direction depending on the individuals' age. The overall quality of evidence was moderate.
SES should be included as part of the routine screening and risk assessment for tooth wear.
评估社会经济地位（SES）与儿童、青少年和成年人牙齿磨损（TW）之间的关联和证据水平。
纳入了评估青少年和成年人恒牙 SES 与 TW 之间关联的基于人群的观察性研究。排除了干预性和描述性研究或无暴露组与非暴露组内部比较的研究。适用时，应用了系统评价和荟萃分析的 Preferred Reporting Items（PRISMA）指南。使用纽卡斯尔-渥太华量表评估偏倚风险（RoB）。进行荟萃分析以估计汇总效应量。Q 统计量、I 统计量、亚组和敏感性分析评估了研究的异质性。
在 1980 年 1 月 1 日至 2021 年 3 月 31 日期间，在 PubMed/Medline、Embase、Scopus、Web of Science、LILACS、SciELO、Cochrane 图书馆和 Google Scholar 数据库中搜索发表在英语文献中的文章。
纳入了 65 项研究，涉及来自 30 多个国家的 63893 名参与者。在青少年中，TW 与教育程度（OR=1.25 [0.96；1.62]）、家庭收入（OR=1.18 [0.91；1.53]）和私立学校（OR=1.24 [0.90；1.72]）呈正相关。受教育程度较高的成年人 TW 风险较低（OR=0.70 [0.52；0.93]）。大多数纳入的研究存在中度 RoB。纳入研究存在与人群代表性和评估方法相关的局限性。
SES 与 TW 相关，其方向取决于个体的年龄。证据的总体质量为中等。
SES 应作为牙齿磨损常规筛查和风险评估的一部分。
