Estimating the effectiveness of lollipops containing xylitol and erythritol on salivary pH in 3–6 years olds: A randomized controlled trial

Abstract

Background: Prevention of dental caries is important for nutrition and health of the child. Sucrose being considered an arch criminal, various substitutes are recommended. Xylitol is an artificial sweetener which cannot be metabolized by bacteria. Thus, it seems to be a promising method in prevention of dental caries. Materials and Methods: Fifty children between the age of 3–6 years were randomly divided into two groups; Group 1: Control group (without lollipops) and Group 2: Experimental group (with sugar substitute lollipops). The saliva sample was collected at four different time intervals, and pH of saliva was determined using universal pH indicator. Results: There was a significant drop in the pH after drinking sweetened beverages in both the groups, but there was a significant rise in pH after having xylitol + erythritol lollipops which almost returned to baseline after 15 min. Conclusion: Lollipops containing xylitol and erythritol can be used in small children and it has potential to increase salivary pH, thus not allowing the pH to fall below the critical value.
