Clinical Trial Summary

investigating the effect of glazing and polishing on the color difference between natural teeth and all ceramic crowns made from celtra press (zirconia reinforced lithium silicate ceramic).

Description:

Two groups of patients will be selected according to special inclusion criteria N=5 in each group total of 10 patients, one of the two groups will receive a glazed zirconia reinforced lithium silicate ''celtra press'' crowns and the other group will receive a polished ones of the same material , after crowns delivery color difference (ΔE) between the natural teeth and the celtra press crown will be measured by a spectrophotometer device (intra oral) and patient satisfaction will be recorded.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	patient satisfaction	Patient satisfaction using Visual Analogue scale- Binary (Satisfied or not satisfied)	immediately after crown delivery
Primary	color match	Color match will be measured using "United states pulplic health service " system .; Scale system : Alpha : Excellent colour match and shade between restoration and adjacent tooth, restoration almost invisible; Bravo : Slightly mismatching between the restoration and the adjacent tooth, which is in the normal range of tooth colour, translucence, and/or shade; Charlie : Obvious mismatch, beyond the normal range; Delta : Gross mismatch/aesthetically displeasing colour, shade, and/or translucence	immediately after crown delivery
Secondary	Color difference	The color difference (?E) will be measured using spectrophotometer	immediately after crown delivery
