Abstract

Introduction: Increasing patients' expectations about restorative therapies and the beauty of researchers encourages researchers to study more about materials and methods that have the desired appearance for patient satisfaction. The purpose of this study was to evaluate theeffect of repeated firing on Color changes of lithium disilicate (with high and low translucency). Materials & Methods: In this in-vitro study, 20 samples of high and low lithium disilicate were prepared forboth groups (n = 10). Samples were sectioned and polished to provide a thickness of 1mm. The specimens were subjected to firing for three times. The Color coordinationafter the first and second firing were measured using spectrophotometer. Delta E was calculated between first and second firing. the data were analyzed by SPSS (version 16) stastical software (α = 0. 05). Results: The mean and standard deviation of low translucency was 1. 342 ± 0. 88 and high transcendental was 0. 757 ± 0. 49. Pair-wise comparison of Color change prepared by three times firing in lithium dicliate samples caused higher Δ E of LDS with low translucent significantly (p value = 0. 019). Conclusion: Multiple firing casued significantly higher Color changes in lithium disilicate with low translucency than that of with high translucent.
