Bayan
After the glaze paste firing cycle is complete, the restoration surface should be examined under magnification to verify the glaze paste created a smooth, glossy, nonporous finish. A successful glaze paste application appears uniform in color and luster across the entire visible surface. Any areas where the glaze paste appears dull, rough, or mottled may indicate inadequate firing, surface contamination, or product incompatibility. If surface irregularities are detected after glaze paste firing, selective polishing or reapplication of glaze paste may be necessary before delivery to the patient.

Can a lithium disilicate restoration be used without glaze paste application?
While lithium disilicate restorations are functional without glaze paste , the lack of surface sealing significantly reduces longevity and esthetic stability. Unglazed restorations exhibit greater porosity, increased susceptibility to staining, and reduced resistance to mechanical wear. Clinical evidence strongly supports glaze paste amfani ne kamar shari'ar mahallin don yin karfi ga taimakawa na sauyi da raiyuka na mutum.
