In vivo evaluation of the enamel wear of primary molar against four types of crowns using the intra-oral scanner.

ABSTRACT:

Background

Primary tooth wear is a common phenomenon that affects chewing ability, dental sensitivity, aesthetics, and occlusion. This study was conducted to compare the antagonistic enamel wear of primary molars opposed to four different crown materials.

Methods

Forty lower second primary molars of children aged 4-8 years were allocated into 4 groups: Group 1 (n = 10): received stainless steel crowns; Group 2 (n = 10): received prefabricated commercially available zirconia crowns (NuSmile^®); Group 3 (n = 10): received locally manufactured zirconia crowns created via the CAD/CAM system; and Group 4 (n = 10): received locally manufactured hybrid ceramic (Vita Enamic^®) crowns created via the CAD/CAM system. All the crowns were cemented with resin-modified
