Risk of mechanical injuries contraindicate elect brushing and chemical agents as appropriate for daily cleaning of dentures (or partial) relined with resilient materials. We evaluated the effect of chemical cleaning agents on the damping capacity of a trademark for acrylic resilient soft liner (Dentusoft, Dental Medrano) a trademark of stone type IV (IV Durone, Dentsply). We used 20 discs of acrylic resin thermoactivated VipiCril ® with 30mm diameter and 4mm thick, covered by 2mm Dentusoft ®. Divided into 4grupos were stored in artificial saliva at 37 +1 º C for 30 days, immersed daily for 15minutes in distilled water (GI), Corega ® Tabs (GII), a solution of sodium bicarbonate (GIII) or solution of sodium hypochlorite (GIV) after which, on the soft liner were poured 2 ml of type IV gypsum (Durone IV, Dentsply). Reached the final setting of the gypsum specimens were sectioned vertically and medially, settled water with sandpaper No. 240 and mounted on suitable device for reading (in the right and left) of the contact angle Carl Zeiss microscope (precisão0, 001). The results were submitted to analysis, showed non-normal distribution, opting for non-parametric test. Kruskal Wallis test performed at 5% significance, there was statistical difference between the groups with lower average contact angle for GII. It was concluded that the chemical cleaning Corega Tabs ® allowed a better adaptation of relining the gypsum studied
