  Purpose

To establish evidence based guidelines for denture adhesives (powder and cream), multicenter cross over randomized clinical trial will be carried out.

The null hypotheses are that there are no difference on improvement from baseline to post application of two adhesives powder and cream, in terms of general satisfaction, oral related quality of life, masticatory function and oral conditions.
