About

the study evaluate the clinical outcome of zirconia versus lithium disilicate overlays restorations for restoring vital young permanent first molar teeth affected with moderate form of molar Incisor hypomineralization: randomized clinical trial.

Full description

To compare the one-year clinical outcome of zirconia versus lithium disilicate overlays restorations. Materials and methods: Twenty patients were distributed into two groups in relation to the material used for the fabrication of overlays restorations; group (Z) (n=10): patients received zirconia restorations, group (EC): patients received IPS E.max Cad restorations. Clinical and radiographic evaluations of these restorations were carried out at base line (1 week), 3, 6 and 12 months after cementation using FDI World Dental Federation criteria
