Outline of Final Research Achievements

The purpose of this study was to clarify the selection criteria for denture adhesives or oral moisturizers in wearers of maxillary complete dentures.
Twenty-five maxillary edentulous subjects were enrolled in this study. A denture adhesive and three oral moisturizers (liquid, gel, and spray) were administered for 3 days each. Patients were surveyed after each treatment and at the end of the study. In the after-use questionnaire, the denture adhesive was evaluated highly for “stability,”“chewing,” “fitting,” and “retention” (P <0.05). On the final questionnaire, the denture adhesive was selected by 14 and the oral moisturizers by 11 of 25 subjects. These results suggest that “stability,” an “uncomfortable feeling,” and a “dry feeling” were the driving criteria in choosing either the denture adhesive or an oral moisturizer.
