* significance P < 0.010, P <0.05 was considered as significant and value<0.001 was considered highly statistically significant. OHI – Oral hygiene index; PI – Plaque index; GI – Gingival index; BI – Bleeding index; PD – Pocket depth; CAL – Clinical attachment loss; SE – Standard error; P – Probability value
