The Impact on Dental Staining Caused by Beverages in Combination with Chlorhexidine Digluconate.

Objectives:  There are several hypotheses regarding how chlorhexidine (CHX) digluconate causes staining with the role of beverages, specifically the precipitation of anionic dietary chromogens onto adsorbed cations, the most probable cause. The aim of this study was to investigate and compare the staining potential of common beverages using an staining and brushing model to better understand the interactions between chromogens from different beverage categories and the teeth.

Materials And Methods:  Human enamel samples were exposed to a cyclic treatment of artificial saliva and 0.
