248 - Comparing Success of Strip Crowns versus Pre-veneered Stainless-Steel Crowns

Purpose: The primary objective of this retrospective study was to evaluate the success of resin (strip) crowns compared to pre-veneered stainless-steel crowns on primary anterior teeth, specifically primary maxillary centrals, laterals and canines in the operating room setting.

Methods: The study involved a review of electronic records from March 2013 to April 2022, focusing on patients treated under general anesthesia (GA) in the operating room (OR). A total of 196 patients were included, comprising 87 females and 109 males, with a mean age of 4.4 years. These children had at least one surface of a cavitated lesion. Only vital, painless teeth were included in the study. After crown placement, treatment success was followed until observed failure or censoring. Kaplan-Meier survival curves with log-rank test were created to compare restoration survival between strip crowns and pre-veneered stainless-steel crowns.

Results: A total of 522 teeth were treated with strip crown or pre-veneered stainless-steel crown restorations, out of which 307 (59%) were pre-veneered stainless-steel crowns and 215 (41%) were strip crowns. There were 101 failures over the course of the study period, 39 failures (13%) were for pre-veneered stainless-steel crowns and 62 failures (29%) were for strip crowns. Strip crowns had significantly shorter survival at 53.2 months median survival compared to not reached (NR) median survival for pre-veneered stainless-steel crowns (P < .001).


Conclusions: The findings suggest that anterior pre-veneered stainless-steel crowns yield superior results compared to anterior strip crowns.
