| Abstract | ||
| Introduction: disinfection of dentures and soft denture liners was prioritized for cross-contamination management and patient safety. However, it has been shown that these approaches have an influence on the physical and mechanical qualities of denture liners. Objective: assessment of the effect of disinfection by sodium hypochlorite and cleansing tablet on surface hardness and roughness of an acrylic-based soft liner. Material and Methods: 15 specimens were prepared for each test, and then divided into three groups (2% NaOCl, Protefix tablet, and control). The specimen’s preparation was done by conventional procedures according to manufacturing instructions. The daily disinfection of specimens was continued for 30 days. After each immersion in a denture cleanser, distilled water was used to maintain the specimens at room temperature. Hardness and roughness measurements were made by shore A durometer and profilometer devices respectively and the results were analyzed by ANOVA test. Results: there were no significant differences in the hardness value between the examined groups, with the high mean value obtained with the cleansing tablet group, whereas the low value was obtained in the control group. When compared to the control group, the soft-liner increased surface roughness significantly in the NaOCl group, but just slightly and not significantly in the cleaning tablet group. Conclusion: the denture cleansers employed in this investigation had no significant effect on the soft liner's hardness. When compared with a control group, sodium hypochlorite significantly increased the surface roughness of the soft liner, while the cleansing tablet was not significantly affected the surface smoothness. | ||
