All participants had professional tooth cleaning at the end of the baseline examination. 1st and 2nd follow up was done after every 4 months. SPSS version 22 was used. The Chi-squire test, student “t” test, paired “t” test and ANOVA test were used. The significance level was set at p<0.05.  Results: At the beginning of study mean MQHI score: 1.38, mean GI score: 0.38 mean OHI-S score: 1.33 and mean PHP index: 2.32. At the end of study, all groups showed improvement in oral health status (p<0.001) except in control group.
