PLAQUE, PLAQUE
The toddlers were randomly assigned to three groups. The first group received a placebo (DW) (negative control). The second group received topical CHX gel (0.2% w/v) (positive control). The third group received topical PVP‐I solution (10% w/v). Each antiplaque agent was applied using a cotton‐tipped swab on tooth surfaces in the clockwise direction. It was applied for one time due to the lack of compliance on the part of toddlers. Plaque accumulation was measured at the baseline (t0 = No plaque.1 = Separate areas of plaque at the cervical margin.2 = A thin continuous band of plaque at the cervical margin (≤1 mm).3 = Plaque covering <1/3 of the tooth (>1 mm).4 = Plaque covering >1/3 but <2/3 of the tooth.5 = Plaque covering 2/3 or more of the tooth.
