Abstract
Purpose: This clinical trial aimed to evaluate the effectiveness of zirconia-based primary anterior crowns with and without retention grooves in children aged 2-6 years.
Methods: Children were randomly assigned to zirconia-based primary anterior crowns either with or without retention grooves. The clinical and radiographic outcomes were evaluated based on gingival health, plaque index, secondary caries, crown failure, tooth wear of opposing teeth, and marginal integrity at a 2-week follow-up. The study utilized the Early Childhood Oral Health Impact Scale (ECOHIS) to evaluate Oral-Health Related Quality of Life (OHRQOL) at baseline and 2-weeks along with parental satisfaction at 2 weeks.
Results: In total, 38 crowns (23 with and 15 without grooves) were placed in twelve patients. At the 2-week follow-up, there were no significant differences in clinical outcomes based on retentive grooves (P>.40). The most common negative clinical outcome was opposing tooth wear which was demonstrated in 7 (18%) crowns, 4 (27%) without grooves and 3 with grooves (13%). However, parents rated the crowns without grooves significantly better in terms of size (52% dissatisfied vs 0%; P =.0008), and marginally better for shape (P =.0634), color (P =.0634), and overall satisfaction (P=.0996). Bleeding around the crown and sensitivity were noted in two crowns without grooves.
Conclusion: Similar success was noted between the crowns (with and without retentive grooves). However, parents preferred NuSmile zirconia crowns for size and showed marginal preference for shape, color, and satisfaction.
