PENGARUH MINUMAN ENERGI TERHADAP STABILITAS WARNA DAN KEKERASAN PLAT RESIN NILON TERMOPLASTIK (Penelitian Eksperimental Laboratoris) = THE EFFECTS OF ENERGY DRINK ON COLOR STABILITY AND HARDNESS OF THERMOPLASTIC RESIN NYLON PLATE (Laboratory Experimental Research)

Background: Removable dentures function to replace teeth that are not in the mouth that can be removed or used by the wearer. These denture materials can be made from metal frames, acrylic resins, and thermoplastic nylon. Currently, the use of thermoplastic nylon is widely used in the field of dentistry. The color stability of resin plates is affected by factors such as exposure to coffee, tea, and energy drinks. Objective: This study aims to analyze the effect of energy drink as an immersion material on the color stability and surface hardness of thermoplastic nylon plates. Methods: In this study, four immersion groups were used consisting of: Aquades, Krating daeng, Kukubima Energ, and Extrajoss. Hardness and color stability checks were carried out before and after immersion for 12 days. The data was then analyzed using the Anova test and sampled Paired T test. Results: the hardness of thermoplastic nylon resin decreased significantly after immersion, with Aquades retaining the highest post-immersion hardness (4.96 HV) and energy drinks such as Kukubima Energ showing the most significant decrease to 4.36 HV. The study found that thermoplastic nylon resins underwent changes in color stability after immersion, with Krating Daeng showing the most significant changes, while Aquades had the highest Delta E L*A*B value (66.31) and Kukubima Energ had the lowest value (12.07). Conclusion: based on the results of the study, there were significant effects and differences on immersion in Energy Drinks: Krating Daeng, Kukubima Energ, Extrajoss on the hardness of thermoplastic nylon resin plates There were significant effects and differences of immersion on Energy Drinks: Krating Daeng, Kukubima Energ, Extrajoss on the color stability of the surface of thermoplastic nylon resin plates.
