description Fiber reinforced composite is a material consisted of matrix and reinforcing fiber. The application of FRC in oral cavity as a splint will form a contact between FRC and saliva with fluctuating pH degree, which is saliva can turn into acidic. The aim of this study was to determine the influence of acidic pH on compressive strength of FRC with UHMWPE fiber. Twelve cylindrical samples of FRC with flowable composite (Master Flow, Brazil) as matrix and UHMWPE fiber (Construct, USA) with 3 mm diameters and 6 mm heights were used in this study. All samples were polymerized for 20 seconds, then divided into 3 groups of immersion consists of pH 2,5, 4,5, and 5,5 (n=4). Samples were immersed into artificial saliva solution for 14 days at 37�C. Compressive strength was measured using universal testing machine with 1mm/min speed of press. Data obtained then analyzed using one way ANOVA and LSD tests. Means of compressive strength from the immersion groups pH 2.5, 4.5, and 5.5 were 54.23 ± 1.84, 92.06 ± 2.71, and 101.95 ± 3.34 MPa. One way ANOVA test showed that acidic pH had significant influence on compressive strength (p<0.05). Least significant difference (LSD) test showed significant difference in treatment group of pH 2.5 to treatment groups of pH 4.5 and 5.5 (p<0.05). Conclusion of this study is there is significant influence of acidic pH on the decrease in compressive strength of FRC with UHMWPE fiber.
