Research оbjective. In order to control the effectiveness of prosthetic treatment of patients with partial removable dentures, we analyzed hygienic condition of the constructions after 1, 6, 12 months of use. Partial dentures were made of thermoplastic polymer (Vertex™ThermoSens) and acrylic polymers (Fluorax, Villacryl H Plus) and finally polished with Blue Shine and ThermoGloss pastes. The aim of the research was to conduct a comparative assessment of the hygienic condition of partial removable dentures made of different polymeric materials using the hygienic condition assessment index. Materials and methods. The hygienic analysis of partial dentures surface made of polymeric materials was carried out using the the hygienic condition assessment index. To determine the index, the internal surfaces of partial dentures were stained with a 5% aqueous solution of erythrosine, after 5–6 seconds the dentures was rinsed with running water, dried for 10 seconds with a stream of air. In this case, pigmentation was observed in the area of soft plaque and in the area of damaged polished layer. The painted surfaces were photographed at an angle of 90̊, after images were superimposed on a plastic template. The hygienic index was determined in points. Scientific novelty. As a result of the study, it was determined that during the 12-month use of removable dentures made of thermoplastic material Vertex™ThermoSens polished with BlueShine paste, demonstrated unsatisfactory state of hygiene – 100%, while the level of unsatisfactory hygiene of such dentures polished with ThermoGloss paste was only 20% (p˂0.05). The level of unsatisfactory hygiene of dentures made of acrylic resins polished with Blue Shine paste reached 100%, while the level of unsatisfactory hygiene of dentures polished with ThermoGloss paste was only 33.0% (p˂0.05) after twelve months of use. Conclusions. The results of the studies suggest that the use of ThermoGloss polishing paste for the final surface treatment of removable dentures with bases made of thermoplastic materials allows to achieve a better result than when using acrylic materials, which will undoubtedly have a positive effect on the fabrication process, use, durability of this type of dentures and improve the quality of dental care.
