The purpose of the present study was to determine the effect of a chewing gum containing 70% xylitol and 0.23% Curcuma xanthorrhiza extract to remove dental plaque and reduce gingivitis when used as a supplement to daily toothbrushing for 3 weeks. The study group consisted of 75 adults with moderate gingivitis. Participants were divided into 3 groups(control 1 group – Gum base, control 2 group – 70% Xylitol, experiment group – 70% xylitol and 0.23% xanthorrhizol) and instructed to chew the study gum for 3 times daily for 3 weeks in addition to regular daily toothbrushing. Chewing xylitol/xanthorrhizol gum significantly reduced plaque index with significant difference by week 3(p<0.01). Gingival index and bleeding on probing were decreased in xylitol/ Curcuma xanthorrhiza extract group by 35.9% and 31.65% each in the same period. No adverse effects on the oral tissues were observed in any of the participants for the duration of the study. In conclusion, regular use of a chewing gum containing 70% xylitol and 0.23% Curcuma xanthorrhiza extract appears safe and effective for the removal of dental plaque and reduction of gingivitis when used in conjunction with daily toothbrushing.
