After being endodontically treated and preparing post spaces for DT light fiber posts, the samples were randomly divided into 4 groups of 10 based on the resin cement type and were submitted to 4000 thermal cycles (5-55c). Then, three 2mm thick segments from coronal, middle and apical thirds of roots were prepared and push out test was performed on them. Then, all root segments were assessed for failure mode using stereomicroscope. From the coronal slices of each group based on dominant failure mode, one slice was randomly selected to be observed under SEM. Data were analyzed using T-test, two way ANOVA and Tukey test.</span></font></p>
