Full description
Evaluation of the marginal and internal adaptation using silicon replica technique, which will be measured by digital microscope and clinical Performance using modified USPHS scoring system of Endo-crowns fabricated from Nano-ceramic Hybrid and Lithium di-silicate ceramic materials.
Primary outcome: Marginal gap of the two groups will be measured using Silicon replica technique, Each replica will be sectioned bucco-lingually and mesio-distally into four segments named (MB, DB, ML, DL) and each segment has five reference points assigned at different positions, An overall of twenty reference points will be measured in each replica sample using a digital microscope.
Secondary outcome:
- Internal gap of the two groups will be measured using Silicon replica technique, which will be measured by digital microscope.
- Clinical Performance of the two groups will be evaluated using modified USPHS scoring system. (Color match, Marginal discoloration, Surface texture and Gross fracture)
