ABSTRACT
OBJECTIVES: Although minimally- and non-invasive caries management are advocated in pediatric dentistry, extensive caries progression often requires endodontic treatment followed by crowning of the tooth. Thus, the aim of this study was to evaluate the success of aesthetic preformed zirconia crowns (PZC) compared to the standard preformed metal crowns (PMC) after pulpotomy in primary molars retrospectively.
METHODS AND MATERIALS: Patient’s digital records in a specialized pediatric clinic in Germany were analyzed to include 2-9-year-olds, who had received one or more PMC or PZC after a pulpotomy between 2016 and 2020. Main outcomes were success, minor failure (restoration loss, wear or fracture), or major failure (need for extraction or pulpectomy).
RESULTS: 151 patients with 249 teeth (PMC: n=149; PZC: n=100) were included. Mean followup time was (19.9 months), with 90.4% of the crowns followed for at least 18 months. The majority of crowns were considered successful (94.4%). The differences in the success rates between PMC (96%) or PZC (92%) did not reach the level of statistical significance (p=0.182). All minor failures (1.6%) were in the PZC group. Especially crowns in first primary molars and the maxilla were prone to failure.
CONCLUSION: PMCs and PZCs both show high clinical success rates as restorations of primary teeth after a pulpotomy. However, there was a tendency of higher minor or major failure in the PZC group.
