Figure 1: Change in gingival index across time in the study groups. Effect of time [F = 430.28, P< 0.0001; a, b, c, and d: Different letters denoting significant difference between follow up period]. Effect of groups [F = 10.12, P< 0.0001; A and B: Different letters denoting significant difference between the follow-up period]
