Success of Zirconia and Stainless Steel Crowns for Permanent Molars

Clinical and Radiographic Performance of Preformed Zirconia Crowns and Stainless-Steel Crowns in Permanent First Molars: 18-Month Results of a Prospective, Randomized Trial

NCT05049694•Hacettepe University

View on ClinicalTrials.gov

Summary

The purpose of this study is to evaluate and compare the clinical and radiographic performance of zirconia and stainless steel crowns on permanent molar

Detailed Description

Zirconia and stainless steel crowns will be placed on at least two permanent molars, in a split mouth design. 100 patients will be included in the study. The teeth will be randomized into two groups according to the crown type. Group 1: Zirconia crown 2: Stainless steel crown. Plaque index, gingival index, crown retention, presence of restoration failure, gingival margin extension and pulpal health of the teeth will be clinically evaluated at baseline and 1., 6., 12., 18., 24. months. The restorations will be evaluated radiographically at 6., 12. and 18. months. Intra-oral photos will be taken directly after treatment and at control appointments. The data will be analysed statistically using Fisher's Exact Test and pearson's chi-square test; and Log-rank and the Kaplan-Meier will be used to estimate survival percentages.
