The Efficacy of Xylitol, Xylitol-Probiotic and Fluoride Dentifrices in Plaque Reduction and Gingival Inflammation in Children: A Randomised Controlled Clinical Trial.



The present prospective, randomised, placebo-controlled, clinical trial was designed to evaluate the clinical effects of a commercially available dentifrice containing fluoride, xylitol or xylitol-probiotic on the decrease of plaque and gingival inflammation in children between 13 and 15 years of age.


Forty-eight adolescents were randomly grouped into three groups of n = 16 each: study group A received xylitol (Xyliwhite) toothpaste; study group B received xylitol-probiotic (Periobiotic) toothpaste; and the control group C received fluoride (Colgate Max Fresh) toothpaste. The subjects were instructed to use the dentifrice determined and a modified Bass brushing technique twice a day for two minutes over a 6-week perioed. Clinical evaluation was performed using a gingival index and a plaque index at baseline and at the end of the 6-week period.


From day 0 to 42, reductions in the plaque index were statistically significant in all groups, Colgate Max Fresh, PerioBiotic and Xyliwhite (p-values 0.001, 0.001 and 0.035, respectively), but reductions in the gingival index were statistically significant only in the Colgate Max Fresh and PerioBiotic groups (both with p = 0.001), not in the Xyliwhite group (p = 0.116). PerioBiotic toothpaste was found to be better than Xyliwhite and Colgate Max Fresh toothpastes at reducing plaque and gingival scores. However, statistically significant differences with PerioBiotic and Colgate Max Fresh toothpaste were not observed.


It was concluded that PerioBiotic was an all-round dentifrice that produced a significant reduction in both gingivitis and plaque.
