Additionally, relevant journals and conference papers were manually retrieved, and relevant randomized controlled trials were collected. Two reviewers independently evaluated the quality of each study and extracted the data. A meta-analysis was performed using the RevMan5.3 software for homogenous studies, and a descriptive analysis was performed for studies with poor homogeneity.ResultsIn total, 10 randomized controlled trials containing 398 isolated teeth were included. The meta-analysis results showed that the difference in apical microleakage was statistically significant at 1 week and 3 months [1 week: MD=-0.13, 95% CI (-0.22,-0.04), P=0.007; 3 months: MD=-1.27, 95% CI (-1.94,-0.60), P=0.0002] but not at 6 months [MD=-0.10, 95% CI (-0.26, 0.06), P=0.23].ConclusionBased on existing research results, GuttaFlow may achieve better results than AH Plus in the short term (≤ 1 week). Because it is subject to limitations of time, quality, and research methods, this conclusion requires more long-term, high-quality, large-sample, multimeasurement randomized controlled trials for further validation.
