Purpose:
The purpose of this study was to compare the clinical success of stainless steel crowns (SSCs) made esthetic by open facing or veneering on posterior primary teeth.
Methods:
Thirty-three crowns (18 open-face and 15 veneered) were placed and followed up for 18 months with semiannual evaluations.
Results:
Crowns made esthetic with the open-face method showed a success of 95%, while the veneered crowns showed a success of 80% based on greater than two thirds facing retention. Statistical evaluation by 2 proportion test showed no significant difference between groups (P>.05). In addition, a statistically significant difference was found between upper and lower crowns by Fisher's exact test (P<.05).
Conclusions:
This study showed that open-face SSCs had a higher but not significantly different success rate than veneered SSCs. Upper-arch crowns exhibited a higher success rate than those in the lower arch.
