- Abstract
Objective: The effect of oil pulling on oral health has not yet been fully demonstrated. Therefore, we performed a meta-analysis to investigate the effect of oil pulling on oral health. Methods: We searched PubMed, the Cochrane Library, and the EMBASE database, limiting the search to human patients and articles written in English and published before 31 July 2022. We included randomized controlled trials (RCTs) comparing the effect of oil pulling on improving dental health and oral hygiene. The outcomes of this study were salivary bacteria count, plaque index, and gingival index. Results: In total, nine RCTs were included in this study. The study showed that salivary bacterial colony (BC) counts were significantly reduced in the oil pulling group compared to the control group [mean difference (MD): 17.55, 95% CI 2.56, 32.55]. There was no significant difference between the two groups (MD: −0.10, 95% CI −0.33, 0.14; −0.05, 95% CI −0.12, 0.02) in plaque index and gingival index score. Conclusions: Based on the results of this meta-analysis, the oil pulling may have a beneficial effect on reducing salivary BC count compared to the control group. There was no significant difference in the plaque index and gingival index score between the oil pulling and the control group. Therefore, future clinical trials should be more rigorous and better reported.
