| Abstract | ||||
| Patient saliva, plaque, or even blood can contaminate dental impressions. Disinfecting impression materials with disinfectants can help prevent contamination. However, these chemicals could alter the surface's roughness and wettability. Objective: This research aimed to investigate how the surface roughness and wettability of addition silicon impression [polyvinyl siloxane (PVS)] change after it was immersed in two different disinfectants [5.25% sodium hypochlorite (NaOCl) for ten minutes and 200 ppm hypochlorous acid (HOCl) for 15 minutes]. Material and methods: Sixty PVS samples (Express STD, 3MESPE, USA). Specimens were separated blindly into three groups, with ten specimens in every group. The specimen was prepared using a ring mold, thirty millimeters in diameter, and three-millimeter wall thickness samples were immersed in two disinfection solutions: NaOCl at 5.25% group and HOCl at 200 ppm group. The group serving as the control received no disinfection. The samples' surface roughness (Ra) was measured using the contact profilometer, while contact angles were measured using a goniometer to determine wettability. Results: This investigation's results indicated that the PVS's Ra and wettability significantly differed from those of the control group. Within the research's limits, 5.25% Naocl for 10 minutes of immersion disinfection influenced the surface roughness and wettability of PVS. In comparison, immersion in 200 parts per million HOCl for 15 mins was more effective as disinfection without affecting the surface roughness or wettability of PVS. Conclusion: Within the limits of this study, 200 ppm HOCl showed promise as an efficient disinfectant that would not adversely affect the wettability and Ra of the impression material. | ||||
