Effect of different chemical cleanser on surface roughness of silicone relining material an in vitro study

The objective of the study was to evaluate surface roughness and to determine the effectiveness of denture cleansers in the disinfection of silicone-based soft relining materials. ilicone soft relining materials were immersed in three different types of cleansers. In the immersion test specimens were immersed in neutral peroxide, sodium hypochlorite, polident, and distilled water for 1440 hours of. Surface roughness of the specimens has been recorded using a White Light Interferometry system. The immersion test revealed significant differences in surface roughness of the silicone soft relining material when exposed to different solutions. Specifically, Polident showed significant differences in surface roughness compared to Neutralperoxide, Sodium hypochlorite, and Distilled water. This suggests that Polident had a distinct effect on the surface roughness of the silicone soft relining material, differing from the other tested solutions.
