Objective The aim of this systematic review was to gain a greater insight into the incidence rates of distal surface caries (DSC) on second permanent molars.Data sources A literature search using the Cochrane Library, Lilacs, Embase and Medline via Ovid retrieved English and non-English language articles from inception to June 2016. The electronic searches were supplemented with reference searching and citation tracking. Reviewers independently and in duplicate performed data extraction and completed structured quality assessments using a validated risk of bias tool for observational studies and categorised the summary scores.Data selection The search yielded 81 records and, after application of inclusion and exclusion criteria, two incidence studies were included in this systematic review.Data extraction The DSC incidence was reported in one study as relative risk (RR = 2.53; 95% CI, 1.55 to 4.14) adjacent to erupted, (RR = 0.83; 95% CI, 0.11 to 6.04) soft tissue impacted and (RR = 1.44; 95% CI, 0.55 to 3.72) bony impacted third molars in comparison to when the third molar was absent with a 25-year follow-up. The second study reported a DSC incidence of 100 surface-years (1% of all sites) with an 18-month follow-up period.Conclusions Both cohort studies indicated that DSC incidence was higher when third molars were erupted in the intermediate term, but greater over the long term for an ageing male population. However, further high-quality research is required to improve the accuracy of these findings.
本系统综述旨在深入了解第二恒磨牙远中面龋的发病率。
通过 Cochrane 图书馆、Lilacs、Embase 和 Medline 经 Ovid 检索，从创建到 2016 年 6 月，检索了英文和非英文文献。电子检索辅以参考文献搜索和引文追踪。评估员独立且重复地进行数据提取，并使用经验证的观察性研究偏倚风险工具完成结构化质量评估，并对汇总评分进行分类。
搜索产生了 81 条记录，在应用纳入和排除标准后，有两项发病率研究纳入了本系统综述。
一项研究报告了 DSC 的发病率，在 25 年的随访中，与第三磨牙缺失相比，萌出的第三磨牙（RR = 2.53；95%CI，1.55 至 4.14）、软组织阻生的第三磨牙（RR = 0.83；95%CI，0.11 至 6.04）和骨性阻生的第三磨牙（RR = 1.44；95%CI，0.55 至 3.72）发生 DSC 的相对风险较高。第二项研究报告了 18 个月随访期间，100 个表面年（所有部位的 1%）发生 DSC 的发病率。
这两项队列研究均表明，在中期第三磨牙萌出时，DSC 的发病率较高，但在长期随访中，随着年龄较大的男性人群，发病率更高。然而，需要进一步的高质量研究来提高这些发现的准确性。
