The effect of soaking thermoplastic nylon denture base in Aloe vera extract and alkaline peroxide on surface roughness: experimental study
Introduction: Thermoplastic nylon is a popular denture base material due to its advantages, flexible, aesthetic and high-temperatures resistance. However, it tends to absorb water, which can increase surface roughness. Thermoplastic nylon denture bases can be cleaned with 75% aloe vera extract and alkaline peroxide. Aloe vera serves as a natural disinfectant for dentures, while most denture users opt for alkaline peroxide as a chemical disinfectant. This study aims to determine the effect of soaking a thermoplastic nylon denture base in 75% aloe vera extract and alkaline peroxide on surface roughness. Methods: This research design is true experimental with a posttest only control design. The samples for this study were thirty-six thermoplastic nylon specimens (Bioplast, cylindrical with a diameter of 20 ± 1 mm with a thickness of 2 ± 0.1 mm), namely 18 specimens soaked in aloe vera extract and 18 specimens in alkaline peroxide for 92 hours to simulate use during 15 minutes per day for 1 year. The samples were then tested and analyzed with an unpaired t test to analyze surface roughness. Results: The test results showed that there was no effect of soaking the thermoplastic nylon denture base in aloe vera extract and alkaline peroxide for 92 hours (1 year) on surface roughness but it was still within tolerable limits p=0.131 (p>0.05), although Judging from the data, the surface roughness value of soaking aloe vera extract is lower than alkaline peroxide. Conclusion: Soaking thermoplastic nylon denture bases in aloe vera extract and alkaline peroxide solutions has no significant effect on surface roughness.
