Compressive Strength Of Fiber Reinforced Composite After Immersion In Citric Acid Of Energy Drink

Background: Energy drink consumption has been popular in people age 18-35 years old. A few literature showed that this can cause damage to teeth and composite due its acidity. The use of fiber reinforced increasing good mechanical properties aesthetic. Fiber shaped fillers withstand mastication forces. restoration material face the complex oral environment succeed clinically. Compressive strength test is needed predict durability materials against Purpose: To determine effect energy citric acid immersion compressive strength. Methods: 32 cylinder samples with 8mm tall 4mm diameter were divided into two groups. first group was immerse distilled water (K1) as control, second (K2) acid. immersed an incubator at ±37⁰C for 7 days. After days, washed water, dried tissue, then undergo Autograph machine crosshead speed 10mm/minute. data analyzed using Independent t-test. Results: mean K1 1469.63 MPa K2 1439.57 MPa. value slightly lower than group, but statistically, there no significant difference between 2 Conclusion: on strength.
