Comparing Clinical Success and Parental Satisfaction of Stainless Steel and Zirconia Crowns on Childrens Primary Molars

What this Trial Is About

This research aims to compare the clinical success and parental satisfaction of prefabricated stainless steel crowns and zirconia crowns used on childrens primary mandibular second molars after pulpotomy treatment for deep, multi-surface caries. The study focuses on dental caries and pulpotomy, assessing how these two crown types affect periodontal health, plaque buildup, tooth wear, and various clinical performance factors such as color match and retention. Two groups of children aged 4 to 5 years will receive either a prefabricated stainless steel crown or a zirconia crown on opposite primary mandibular second molars using a split-mouth design. Treatments include pulpotomy followed by crown preparation and cementation using specific dental materials and procedures. The crowns will be cemented with FujiCEM Evolve, and detailed preparation methods differ between the two crown types to ensure proper fit. The study will continue until all follow-up visits are completed and data finalized. Participants will be evaluated at baseline, then at 1, 3, 6, and 12 months after treatment. Assessments include periodontal health indexes, plaque accumulation, opposing tooth wear, and clinical performance measures such as marginal integrity and postoperative sensitivity. Parental satisfaction will also be measured at these intervals. Intraoral photographs will be taken immediately after treatment and during each follow-up to document changes. The study monitors for clinical success factors and potential failures such as crown decementation or tooth abscesses.
