| Abstract | ||
| Aim: The aim of this research is to to study the effect of different thicknesses of three ceramic materials on the water sorption of light cured resin cements Materials and methods: A total of 60 ceramic disc specimens were divided into 3 groups according to the type of ceramic into group (E): E.max CAD, Group (V): Vita Suprinity and Group (C): Celtra Duo (n=20). Each group was subdivided into 2 groups of different thicknesses; 0.4mm and 1mm thickness. Opaque light cured Bisco resin cement specimen was made of a thickness of 0.1mm controlled using a teflon mold and cured through each ceramic specimen then inserted into the dessicator inside an incubator. The specimens were repeatedly weighed after 24h intervals using analytical balance of accuracy 0.001 g until a constant mass (m1) was obtained. The water sorption for the seven days of storage in water was calculated and the data was collected, tabulated and statistically analyzed. Results: There was a significant difference between samples of different materials (p < 0.001). The highest value was found with Emax samples (32.52±3.05) followed by Celtra Duo (24.88±2.35) while the lowest value was found with Vita Suprinity (23.36±2.39) while There was no significant difference between samples made with different thicknesses (p=0.376). Conclusion: There is a relationship between ceramic type and water sorption between the zirconia reinforced lithium silicates and lithium disilicate ceramic materials and on the other hand, different ceramic thicknesses up to 1mm did not affect the water sorption of the light cured resin cement. | ||
