Background
denture, denture adhesives, edentulous
Complete edentulism is one of the major challenges facing the elderly populations. The majority of these patients experience difficulties with different oral functions including chewing, eating, and speaking. These difficulties can profoundly affect their oral health-related quality of life [The retention of complete dentures depends on the the interaction of various physical mechanisms, including adaptation to the supporting tissues, the presence of thin film of saliva between the intaglio of the denture and tissues, adequate peripheral edge extension, and atmospheric pressure [Denture adhesives are commercially available, nontoxic, nonmedical soluble products that have attracted more attention since guidelines for their use were published in 2019 by the Oral Health Foundation [Numerous studies have consistently demonstrated that denture adhesives help improve the retention and stability of complete dentures, improving the quality of life and satisfaction of patients [Although denture adhesives are widely accepted by patients, dental professionals have been reluctant to endorse them. Patients may use denture adhesives indiscriminately without proper prescription by the dentist, leading to dissatisfaction [The aim of this randomized clinical trial was to compare the reported outcomes and oral health impact profile for edentulous patients before and after using 3 different types of denture adhesives. The null hypotheses were that there would be no significant differences in patient satisfaction, as measured by visual analog scale (VAS) scores or oral health impact profile for edentulous patients (OHIP-EDENT) scores before and after using each type of adhesives, and that these differences would not be significant between the 3 types of adhesives.
