Plaque index and gingival index
After six months, no significant differences were reported for GI and PI scores. The PI mean was reported to be (0.4±0.7) in Group 1 and (0.4±0.52 and 0.4±0.52) in Groups 2 and 3, respectively. There was no statistically significant difference between baseline and 6-month follow-up between the three groups (p > 0.05) and no significant difference between the three groups (P > 0.05). Again, no significant differences were reported at 6-month GI compared to baseline. Mean GI was 0.60±0.52 at baseline and 0.7±0.67 after 6 months in Group 1, and changed from 0.60±0.70 to 0.50±0.52 in Group 3, remaining constant in Group 2 (P > 0.05); thus, no statistically significant difference was noted between the three groups (P > 0.05) (
