Brief summary

Dental plaque accumulation is a common problem in toddlers. A randomized controlled trial was conducted to compare the efficacy of CHX gel and PVP-I solution in suppressing dental plaque regrowth in toddlers. The study included forty-five healthy toddlers aged 24-36 months who were randomly assigned to three groups. The first group received a placebo (distilled water (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). Plaque accumulation was measured at the baseline (t0), after three days (t1), and after 7 days (t2) using the Turesky modified Quigley-Hein plaque index (TMQHPI). Oral hygiene practices were prohibited during the trial period. CHX and PVP-I efficacy lasted only for three days, and PVP-I was not superior to CHX in terms of plaque control in toddlers.

Interventions

The toddlers were randomly assigned to three groups. The first group received a placebo distilled water (negative control). The second group received topical chlorhexidine gel (0.2% w/v) (positive control). The third group received topical povidone iodine solution (10% w/v). The antiplaque agent was applied using a cotton-tipped swab. Plaque accumulation was measured at the baseline (t0), after three days (t1), and after 7 days (t2) using the Turesky modified Quigley-Hein plaque index (TMQHPI).

Plaque accumulation was measured at the baseline (t0), after three days (t1), and after 7 days (t2) using the Turesky modified Quigley-Hein plaque index (TMQHPI). Dental plaque was disclosed using the two-tone erythrosine-free plaque disclosing dye solution Mira-2-Ton® (Hager & Werken, Duisburg, Germany). The toddler’s legal guardians were instructed to avoid feeding their child for 30-60 minutes post-antiplaque agent application and oral hygiene practices were prohibited during the trial period. The dose administered: 2 ml. The duration of administration: single application. The mode of administration: topically applied by dentist.
