Dental Restoration Clinical Trial
Official title:
Comparative Clinical Evaluation of BioFlx, Zirconia, and Stainless-Steel Crowns in Primary Molars: A Randomized Controlled Clinical Trial
This study will be conducted to: Evaluate and compare the clinical success, periodontal changes, and wear of antagonist teeth for three types of prefabricated crowns in primary molars: BioFlx crowns, Zirconia crowns, and Stainless Steel crowns.
A randomized controlled clinical trial with three parallel groups, will be set up and reported according to the revised Consolidated Standards of Reporting Trials statement. The study will be conducted on 51 children with 51 molars aged between 4 and 7 years with a lower primary molar indicated for crown restoration. The children will be selected from the Pediatric Dental Clinic, Faculty of Dentistry, Mansoura University. They will be randomly divided into three equal groups (17 molars/each). Sequence generation and concealment will be done by a biostatistician who is not involved in the study. Group I (control group) will include stainless steel crowns, group II (study group) will include Zirconia crowns, group III (study group) will include BioFlx crowns. After obtaining the written consent form from the parents or guardians, the children will be randomly enrolled, and teeth will be assigned to the groups to receive the selected crowns. Clinical evaluation will be done concerning crown retention, color stability, secondary caries, periodontal changes, and wear of the opposing natural enamel. All crowns will be evaluated at the 3rd, 6th, 12th, and 18th months. ;
