Clinical evaluation of two different methods of stainless steel esthetic crowns.
OBJECTIVE
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.
