The clinical and radiographic success of bonded resin composite strip crowns for primary incisors.
OBJECTIVE
The aim of this study was to examine the clinical and radiographic success of the treatment of maxillary anterior primary incisors with composite resin strip crowns placed in a private practice setting.


METHODS
This was a retrospective, clinical study of patients who had strip crowns (SC) placed on maxillary primary incisors, returned for at least 1, 6-month recall examination, and whose parents consented to participate in the study. Radiographic and photographic examinations were used for evaluation. Two evaluators rated the images independently. When ratings were not in agreement, the 2 examiners reviewed the photograph or radiograph together and reached a consensus rating.


RESULTS
One hundred twelve restorations placed in 40 children were evaluated. The evaluations were performed after the crowns had been in place for an average of 18 months. None of the restorations were totally lost, and only 12% were rated as having lost some resin material, resulting in an 88% overall retention rate. There was no difference in restoration success if the crowns were placed 4 at a time, or if fewer crowns were placed in a single sitting; the failure rates were comparable. Teeth that had pulpal treatment were judged to have far more significant color match discrepancies than those teeth without pulpal treatment. Ninety-one percent of the teeth demonstrated healthy pulps. Eight percent had some pulpal changes but did not require immediate attention. Only 1 tooth showed radiographic evidence of pulpal necrosis. Only 11 teeth had pulpal treatment, but of these, 10 demonstrated clinical success.


CONCLUSIONS
Composite resin strip crowns for restoring primary incisors with large or multisurface caries performed well. Color match of these crowns with adjacent teeth may be significantly reduced when placed upon teeth that have undergone pulpectomy treatment and have been obturated with an iodoform paste. However, based upon the results of this study, the strip crown may provide an esthetic and durable restoration for carious primary incisors.
