Title Xylitol Chewing Gum May Reduce Enamel Erosion If Chewed Concurrently With The Presence Of An Acidic Agent
Clinical Question In an adult population does the use of xylitol gum prevent enamel erosion?
Clinical Bottom Line Xylitol chewing gum may reduce enamel erosion if chewed concurrently with the presence of an acidic agent.

#1) 18195513Chunmuang/200784 extracted human 3rd molarsin vitro Lab study
Key resultsNo significant difference was found between xylitol and xylitol + fluoride combined with the orange juice (p<0.05); these 2 groups resulted in the smallest erosion depth and the highest surface hardness. Post-treatment with xylitol was not significantly different than no intervention (p<0.05), resulting in the largest erosion depth and lowest surface hardness.

The Evidence
This lab study used 7 test groups, all similar at the start and with 100% completion. All groups were treated the same. The study was not double-blind. No statement was made regarding competing interests.
Applicability This in vitro study did not reveal any potential harm to patients. The benefit of reduced enamel erosion indicates that xylitol is a good recommendation for patients with enamel erosion, but only if the xylitol is present in the mouth at the same time as the acidic agent, which reduces the applicability of this evidence. While this study demonstrates that xylitol gum could be used to reduce erosion, there are concerns with the practicality of recommending this, as patients may be unable or unwilling to chew gum at the same time that the acidic agent is present.
