Evaluating the Performance and Efficiency of Zirconia Crowns in Treating Primary Teeth
In Brief
A clinical study evaluating Locally Made Zirconia Crowns and ZR Zirconia Crwons NuSmile ® Crowns for Primary Teeth. Completed, enrolled 60 participants across 1 site.
Detailed Summary
This randomized clinical trial aims to compare the clinical outcomes of two full-coronal-coverage restorations (locally-made preformed Zirconia crowns \[LMP\] and NuSmile Zirconia crowns \[Nu/ZR\]) in treating carious primary teeth. Amongst the children attending the clinics of the Dental School at Damascus University, the ones having an indication for crowns restorations will be screened and if they are conformant to the inclusion criteria then they will be recruited until 60 teeth are reached (30 teeth for LMP/ZR restorations and 30 for Nu/ZR restorations).

Timeline
Interventions
Occlusal reduction by decreasing the occlusal surface to less than the natural occlusal profile by about 1-1.5 mm roughly. Proximal reduction by unfastening the interproximal contacts. The tooth should be trimmed down circumferentially by around 0.5-1.25 mm as needed. Subgingival reduction, leaving no undercuts or subgingival ridges, about 1-2 mm subgingivally on every area should be prepared. Completion of the preparation by eliminating sharp lines and pointed angles to allow all prepared areas to be marginally rounded and smoothed. Locally Made Zirconia Crowns are fixed using Glass Ionomer cement (Fuji- Jaban).
