To evaluate the scientific evidence regarding the association between malocclusion and dental caries in adolescents.
Searches were conducted of six electronic databases, complemented by manual searching of the reference lists of the selected articles and grey literature. Two independent reviewers performed the selection of the articles, data extraction and the evaluation of the risks of bias through an assessment of methodological quality. Meta-analysis was performed considering the mean decayed, missing and filled teeth (DMFT) index for caries and the Dental Aesthetic Index (DAI) for malocclusion. Heterogeneity was tested using the I statistic and a random effect model was employed. Summary effect measures were calculated as differences in means.
The initial search retrieved 2644 studies, only 15 of which were selected for full-text analysis. Four cross-sectional studies were included in the qualitative systematic review. Only one of these studies found no association between malocclusion and dental caries. The meta-analysis of three studies demonstrated that a lower DAI value was significantly associated with a lower mean DMFT index, except for the comparison of DAI 26-30 vs. 31-35.
Based on the studies analysed, the scientific evidence indicates an association between malocclusion and dental caries.
评估关于青少年错牙合畸形与龋齿之间关联的科学证据。
检索了六个电子数据库，并通过人工检索所选文章的参考文献列表和灰色文献进行补充。两名独立评审员进行文章筛选、数据提取，并通过评估方法学质量来评估偏倚风险。采用龋均（DMFT）指数评估龋齿情况，采用牙美学指数（DAI）评估错牙合畸形情况，进行荟萃分析。使用I统计量检验异质性，并采用随机效应模型。汇总效应量以均值差异计算。
初步检索获得2644项研究，仅15项被选作全文分析。定性系统评价纳入了四项横断面研究。其中只有一项研究未发现错牙合畸形与龋齿之间存在关联。对三项研究的荟萃分析表明，除了DAI 26 - 30与31 - 35的比较外，较低的DAI值与较低的平均DMFT指数显著相关。
基于所分析的研究，科学证据表明错牙合畸形与龋齿之间存在关联。
