Resumo:Abstract Objectives: To determine the impact of denture hygiene solutions on the physicochemical properties of acetal material used for dental prosthesis production. Methods: The study used T.S.M Acetal, immersed in denture hygiene solutions. The samples were divided into five groups: a control group, a group immersed in distilled water, and three groups immersed in a dental hygiene solution: Multiclean Roko powder for thermoplastics, Corega Tabs, and Protefix® Hygiene, respectively. After immersion, tests for hardness, impact strength, flexural strength, and sorption were conducted. Statistical analysis of the collected results was performed in Statistica 13.3. The normality of the distribution was checked using the Shapiro-Wilk test. When values were p>0.05, considered as a normal distribution, a parametric analysis of variance ANOVA followed by a post-hoc test was performed. Results: After immersion of acetal in Corega Tabs and Protefix® Hygiene solutions, hardness significantly decreased. The unnotched impact strength test revealed an increase for all groups, whereas the notched impact strength decreased significantly, except for the Multiclean Roko solution group. Flexural strength after solution immersion did not differ significantly from the control group, except for the Corega Tabs group. The sorption study revealed a large decrease for the Corega Tabs (2,2 μg/mm3) and Protefix® Hygiene groups. Conclusions: The Multiclean Roko cleaning agent for thermoplastic materials has the least impact on material hardness, so its use for the hygienization of acetyl-based restorations seems justified. The impact of other agents on thermoplastic material hardness might increase abrasive wear, which should be investigated in further studies.
