“…After that, the wax blocks were placed in a dental stone with the metal spacer (10mm, 10mm, and 3mm in dimensions) dividing two wax blocks for a soft-liner film. The acrylic resin mold was created after the wax blocks were eliminated (7,8). The CAD/CAM-based PMMA polymer (NHT, Latvia) was used to prepare the acrylic sample blocks by CAD/CAM machine (imes-icore, 250i, Germany) as shown in Fig.…”

Disinfection of dentures and denture liners was desired for cross-contamination prevention and improved safety. Nonetheless, it has been discovered that these procedures impact the physical and mechanical features of denture liners.To assess the impact of different disinfection procedures on the tensile bond strength of an acrylic-based soft liner with CAD/CAM-based acrylic denture resin. Material and Methods: 25 specimens were collected and randomly divided into five groups (sodium hypochlorite, chlorohexidine, cleansing tablet, microwave, and control groups), following the daily disinfection protocol, the samples were stored at room temperature (23±2°C) in distilled water. After 30 days, the tensile bond strength was determined using universal testing equipment (Gester, China). The specimens were subjected to force by the machine at a steady crosshead speed of 5 mm/minute till the failure was recorded. The data were analyzed using statistics software (SPSS). Results: Showed that the control group had a higher mean value for bond strength, whereas the chlorhexidine group had a lower value. There was no significant difference between the control and cleansing tablet groups. However, they were significantly different from the microwave, CHX, and NaOCl groups. The NaOCl soft liner group is significantly different from all the other groups. No significant difference is found between microwave and CHX disinfected liner groups. Conclusion: The tensile bond strength of all disinfected soft liners decreased as compared with the control, which was not significant with the protefix tab but significant with the NaOCl, CHX, and microwave groups.

Disinfection of dentures and resilient denture liners were preferred for cross-contamination treatment and better safety. Nevertheless, it has been found that these techniques affect the physical and mechanical properties of denture liners. Objective: To evaluate the impact of various disinfection methods on the tensile bond strength of acrylic soft liner. Material and Methods: 25 samples were made, then divided randomly into five groups (4 disinfection groups as well as a control group), after the daily disinfection procedure, distilled water was used to store the samples at room temperature. After 30 days, a universal testing device (Gester, China) was used to assess the tens ile bond strength. The machine applied force to the specim ens at a crosshead constant speed of 5 mm/minute until failure was recorded. Statistics software (SPSS) was used to analyze the measurements. Results: After 30 days of regular ex posure to different disinfection methods, a greater mean value for bond strength showed in the control group while the lesse r value was in the chlorhexidine group. No significant difference was found between the control and Protefix tablet groups. The sodium hypochlorite and microwave groups had no significant difference between them, but they were significantly different from the control, Protefix tablet, and chlorhexidine groups. the chlorhexidine group was significantly different from the control and other disinfected groups. Conclusion: All disinfected soft liners revealed a decrease i n tensile bond strength, which was not significant with the protefix cleansing tablet but significant with the chlorhexidine, sodium hypochlorite, and microwave regimes.

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.
