Composite resin can undergo discolouration if exposed to dyes. The use of apples can whiten teeth because they contain ma-lic acid. True experiment research with pretest-posttest with control group design using 24 samples divided into 6 treatments, namely sample groups 1 and 2 (nanofiller and nanohybrid composite groups that have been discoloured soaked in apple fruit juice (Malus sylvestris Mill) 80% concentration, groups 3 and 4 (negative control group, discoloured nanofiller and nanohy-brid composites soaked in distilled water) and groups 5 and 6 (positive control group, discoloured nanofiller and nanohybrid composites soaked in 10% carbamide peroxide). The colour change was determined with a shade guide (Vitapan Classical). The results were normally distributed and homogeneous. One-way Anova test showed there was a significant difference in each group. In the independent t-test, there was a significant difference in colour change between nanofiller and nanohybrid composite resins that experienced discoloration in 80% apple juice immersion. It was concluded that nanofiller composite resin had lower discolouration compared to nanohybrid.
