To systematically review the effect of different types of water sources on dental unit waterline (DUWL) contamination. 5 databases were searched from their inception to December 23, 2023. Two reviewers independently extracted the data and assessed the quality of the literature. The risk ratio (RR) was used as measure of effect size in meta-analysis. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) was used for evaluating quality of the evidence. Meta-analysis was completed by RevMan 5.4.5 studies involving 561 water samples were quantified for meta-analysis. The results indicated that no significant differences were found in view of contamination rate (RR = 1.01; 95 % CI, 0.72-1.41; = 0.96, = 62 %; GRADE low)and detection rate of (RR = 0.78; 95 % CI, 0.15-4.13; = 0.77; = 83 %; GRADE very low) between using purified water and tap water as water sources of DUWL. The available evidence suggests that there is no significant difference between purified water and tap water in controlling DUWL contamination. However, the conclusions need to be further validated through more randomized controlled trials with robust design and a large sample size.
系统评价不同类型水源对牙科设备水线（DUWL）污染的影响。检索了5个数据库，检索时间从建库至2023年12月23日。两名评价者独立提取数据并评估文献质量。在荟萃分析中，风险比（RR）用作效应大小的衡量指标。采用推荐分级、评估、制定与评价（GRADE）方法评估证据质量。通过RevMan 5.4.5完成荟萃分析。对5项涉及561个水样的研究进行量化以进行荟萃分析。结果表明，在将纯净水和自来水用作DUWL水源时，污染率（RR = 1.01；95%CI，0.72 - 1.41；I² = 0.96，P = 62%；GRADE低）和[具体细菌名称]的检出率（RR = 0.78；95%CI，0.15 - 4.13；I² = 0.77；P = 83%；GRADE极低）方面未发现显著差异。现有证据表明，在控制DUWL污染方面，纯净水和自来水之间没有显著差异。然而，这些结论需要通过更多设计严谨且样本量较大的随机对照试验进一步验证。
