Effect of sugar-free chewing gum on plaque and gingivitis among 14-15-year-old school children: A randomized controlled trial.

The aim of the study was to find out the effect of sugar-free chewing gums (xylitol and sorbitol) on plaque and gingivitis among 14-15-year-old school children.

A single center, double-blind, randomized controlled trial was conducted on 14-15-year-old children. Sample size was determined to be 48. Participants were randomly allocated to test group (xylitol [n = 12], sorbitol [n = 12]) and control group (no gum, n = 24). Duration of the study was 14 days. Baseline assessment of plaque, gingival, and bleeding score, followed by oral prophylaxis. Selected children received daily two chewing gum (1.1 g each) to chew for 20 min postbreakfast and postlunch. Follow-up was done on 15^th day. Analysis was done using independent t-test, ANOVA, and post hoc test. Significance level was kept at P < 0.05.

There was a significant reduction in plaque, gingival, and bleeding score in test group (P < 0.05) compared to control group.Sugar-free gum (xylitol and sorbitol) significantly reduced the plaque, gingival, and bleeding score.
