CRISTINA BICA, PAUL PESCARU, ADA STEFANESCU, MIHAELA OANA DOCAN, KRISZTINA MARTHA, DANIELA ESIAN, DIANA CERGHIZAN APPLICABILITY OF ZIRCONIA-PREFABRICATED CROWNS IN CHILDREN WITH PRIMARY DENTITION Zirconia dioxide represents the current alternative in restoring primary teeth, being the most promising restorative material through its properties that offer. Zirconia crowns main properties are its aesthetics, resistance to fracture and compression, biocompatibility, alternative for the patients that are allergic to Ni-Cr. This cross-sectional study pointed out the correlations between the rate of applicability of the Ni-Cr crowns and the ZrO2 crowns, as well as the range of applicability of the ZrO2 crowns on temporary teeth among practitioners. The method of choice in the case of extensive carious lesions treatment on the primary teeth was the restoration using filling materials. From the 33,2% of the dentists who decide to apply a pedodontics crown, 75% use the Ni-Cr crowns, and only 25% of them choose the ZrO2 crown (p<0.0001). The applicability of ZrO2 crowns in pediatric dentistry is quite reduced, despite their physiognomic advantages, their excessive cost can also be an impediment for the patient’s parents.
