The diagnosis of side effects in prosthetic dentistry is a demanding challenge for clinicians for many years, so that innovative approaches for a direct evaluation of dental materials are highly expected. The aim of this study was to find practical solutions for inexpensive intraoral assessment of metal-based dentures’ quality in use, and to clinically analyze the important indicators of their applicability. Examination data of 90 wearers of non-precious alloys-based fixed and removable dentures (aged 42-68) with – 48 (53.3%) experimental cases, and without – 42 (46.7%) controls, respectively, suspected of galvanically-induced oral discomfort, was collected. Clinical trial (foil, potentiometric and immersion tests) results were evaluated using the rating scales. Data was analyzed by Mann-Whitney U test in SPSS. Comparing the foil test and the potentiometric results, a distinct difference (p<0.05) was found, with higher mean ranks in the experimental cases. However, the difference of surface discoloration was not statistically significant (p>0.05). Thus, patient’s clinical examination scheme enabled us to confirm or deny galvanically-induced irritation, which was decisive for dental material biocompatibility and denture construction applicability.
