What the trial is, and whether it could suit you

Evaluation and understanding of clinical success, parental satisfaction and effects on periodontal tissues are the main expected benefits of prefabricated zirconia crowns and prefabricated stainless steel crowns. For a long time, stainless steel crowns have been the restorative material of choice for children's primary and permanent posterior teeth. Today, prefabricated zirconia crowns are more popular than other options because they meet aesthetic expectations and have high mechanical strength. The aim of this study is to evaluate and compare the periodontal health, plaque accumulation, opposing tooth wear, parental satisfaction, and clinical performance (color match, retention, marginal integrity, marginal discoloration, anatomic form, secondary caries, surface roughness, surface gloss and postoperative sensitivity) of pediatric prefabricated stainless steel and zirconia crowns applied
