459 - Outcomes of Strip Crowns Placed in Clinic and Operating Room

Purpose:  to determine the success and failure rates of resin crowns placed in clinic compared to those placed in the operating room.

Methods: A 3-year chart review of patients seen in The UPMC Children’s Hospital of Pittsburgh from the dates of 7/7/2017 – 12/31/2020. How long the resin crowns lasted, cause of failure, isolation used, Frankl score, and sedation modality were recorded between two groups.

Results: The Clinic Group had 26% failures, 28% exfoliated, and 46% retained. The Operating Room Group had 17% failures, 27% exfoliated, and 56% retained.  P value for Frankl score in the clinic group was not statistically significant (P-value = .129). P value for  isolation was statistically significant (P-value = .029). The results showed that resin crowns placed in the operating room had fewer failures than resin crowns placed in the clinic. In the clinic group, behavior was not statistically significant in failure rate. However, the type of isolation used was significant.
