To perform a systematic review regarding studies that investigated the association between contextual socioeconomic factors and tooth loss.
MEDLINE, Embase, and LILACS databases were searched and no language or date restrictions were applied for this research. The search was also carried out at the Brazilian Library of Theses and Dissertations (BDTD), with the objective of seeking unpublished studies. We evaluated the bibliographical and methodological characteristics of the studies, as well as the findings.
We found 348 articles, out of which only 6 were included in this study after revision by 2 independent researchers. We also identified an unpublished thesis. In general, these results show that the socioeconomic context interferes in tooth loss. We found an association between the highest number of missing teeth with less favorable contextual variables, despite the weak evidence, due to the fact that all selected studies had a cross-sectional design.
We suggest the standardization of outcome formats and exposures in order to favor the comparison between studies and their quantitative analysis.
对调查背景社会经济因素与牙齿缺失之间关联的研究进行系统综述。
检索了MEDLINE、Embase和LILACS数据库，本研究不设语言或日期限制。还在巴西论文与学位论文图书馆（BDTD）进行了检索，以查找未发表的研究。我们评估了这些研究的文献学和方法学特征以及研究结果。
我们找到了348篇文章，经2名独立研究人员修订后，本研究仅纳入了其中6篇。我们还识别出一篇未发表的论文。总体而言，这些结果表明社会经济背景会影响牙齿缺失。我们发现牙齿缺失数量最多与不太有利的背景变量之间存在关联，尽管证据薄弱，这是因为所有入选研究均采用横断面设计。
我们建议对结果形式和暴露因素进行标准化，以利于研究之间的比较及其定量分析。
