dc.description.abstractPurpose: Since conventional composite resins have some disadvantages such as polymerization shrinkage and secondary caries formation, indirect restorations are preferred in cases where tooth tissue loss is high. The aim of this study is to examine the water absorption and color change of indirect composite resins in different beverages. Materials & Methods: In the study, 40 specimens (10×2 mm) were arranged from each composite using three indirect (Signum Composite, Signum Ceramis and Gradia Plus) and one conventional (GrandioSO) composite resin. After the specimens were polished, they were used for water absorption and color change test. The water absorption test was performed through keeping them in water for 7 days as specified in ISO 4049:2009. Samples were kept in coffee, tea and distilled water for 7 days in order to examine color differences. The water absorption and color change values of the composite resins at the end of the 7th day were appraised using one-way analysis of variance (ANOVA) and Tukey’s test (p<0.05). Results: While there was no statistically considerable difference between the water absorption data of the indirect and traditional composite resin materials we used in the study (p>0.05). When the color changes of resin-containing composites in water, coffee and tea were examined, traditional composite resin (GrandioSO) showed statistically less color change than indirect composites in water, coffee and tea (p<0.05). Conclusion: Although indirect composite resins showed similar water absorption with conventional composite, they showed more color change than conventional composite. The highest color change in indirect composites was seen in coffee solution. Particle size of the indirect composites do not affect water absorption, but the decrease in particle size of composites shows less color change.tr_TR
