For Data extraction, two reviewers blind and independently extracted data from abstract and full text of studies that included.Moreover mean difference with 95% confidence interval (CI), fixed effect model and invariance method were calculated. Random effects were used to deal with potential heterogeneity and I² showed heterogeneity. I² values above 50% signified moderate-to-high heterogeneity. The Meta analysis have been evaluated with the statistical software Stata/MP v.16 (The fastest version of Stata).

Result: subgroup meta-analysis showed no statistically significant difference of Plaque index, Sulcus bleeding index and Probing depth between control group vs children group (MD, 0.07 95% CI -0.09, 0.23. P<0.05), (MD, -0.17 95% CI -0.30, -0.04. P>0.05), (MD, -0.01 95% CI -0.05, 0.03. P>0.05), Respectively.
