Online Published on 23 July, 2024. Abstract Aims and objective The aim of this study was to assess effect of various beverages on mechanical properties of thermoplastic materials. Materials and Methodology 180 thermoplastic samples of three different components (Group I- Hardcast, Group II- Duran, Group III- Bioplast) were thermoformed and were divided into 5 subgroups according to the type of beverage used (Subgroup a- Artificial saliva, Subgroup b- Carbonated drink, Subgroup c- Coffee, Subgroup d- Green tea, Subgroup e- Energy drink). All the samples were immersed for 10 minutes everyday for 2 weeks and air dried for the testing of their mechanical properties (Yield strength, elongation and elastic modulus) with the help of Servo Controlled Dynamic Universal Testing Machine. Results and Conclusion All the above-mentioned thermoplastic materials tested showed an insignificant (p > 0.05) difference in yield strength, elongation and elastic modulus after exposure to different beverages.
