Abstract
The aim of this study was to evaluate the clinical and radiographic success and parental acceptance of a preformed composite crown (PTC) for primary molars and compare with that of conventional stainless steel crowns (SSC). A total of 38 children (Girls:12, Boys:26) in five-nine age range, selected from among patients attending the pediatric dentistry clinic. Seventy-sixth crowns were applied in a split-mouth design with a random allocation for mandibular primary 1st and 2nd molars. Assessment of the clinical and radiographic performance of the restorations was performed by two calibrated examiners during 12-month follow-up period and parental satisfaction was determined for both crowns.Total clinical success rates were 100% and 63% for SSCs and PTCs, respectively, at the end of 12-month follow-up, and the difference was statistically significant (p<0.05). Despite the high rates of cementation and endodontic failures, parents were much more satisfied with PTCs (p<0.05). It has been determined that SSCs is more successful than PTCs, but PTCs were preferred by parents due to their aesthetic features.Despite the high rate of aesthetic satisfaction in the PTC group, studies are needed to evaluate the coronal leakage factor in terms of its potential to cause the problems of "falling out of crowns" and "endodontic problems", observed as clinical failure.
