Abstract
Patients with xerostomia have difficulties using dentures. Application of denture adhesives (DAs) can improve the stabilization of prostheses. The aim of the study was to determine the retention capability of complete maxillary dentures in patients with xerostomia, determined with and without the use of prosthetic DAs. This study evaluated the retention force of prostheses in a group of 60 patients diagnosed with xerostomia. Completely edentulous patients were classified into groups and all used the same kind of DAs during the study. The evaluation was performed 1, 3 and 6 h after application. All patients had poor retention of maxillary dentures without DAs. Maxillary denture retention was much better when DAs were used. The majority of the DAs used were most effective in terms of retention after 1 h. Denture adhesives in the form of glue had the best retention in this study of patients with xerostomia. The results of the present study revealed the impact of DAs on average retention forces in complete maxillary denture patients with xerostomia. Patients affected by a reduced secretion of saliva have difficulties using prosthetics. In some cases, such use becomes impossible because of a complete lack of retention. The application of DAs could be a solution in these cases. Denture adhesives in glue form had the best retention during the study for patients with xerostomia.

Summary
Two of the conditions determining the success of prosthetic treatment are good retention and stability. The retention of prostheses is influenced by a number of factors, in particular, cohesion, adhesion, atmospheric pressure, capillary force, and the viscosity of saliva. The mutual interaction of these factors contributes to the force which holds prostheses. The 2 primary factors are the surface tension of the liquid layer (between the prosthesis and the mucous membrane) and the friction which occurs during the flow of liquid in capillary spaces, on both mating surfaces between the liquid and the prosthesis. One condition for the occurrence of these forces is a layer of saliva in the space between the prosthesis and the oral mucous membrane.[1,2,3].
