Long-term results of crown fragment reattachment techniques for fractured anterior teeth: A retrospective case-control study

摘要

Objective Among the techniques used by pediatric dentists for the crown fracture is the fragment reattachment. The aim of this study was to evaluate the long-term survival of the tooth reattachment in comparison to the composite restoration technique. Methods The study included 67 patients aged 7-9 years (males 38/56.7%; females 29/43.3%), with noncomplicated fractures of permanent teeth. The patients were divided into two groups; group A included 32 patients (males 18/56.2%; females 14/43.8%; total number of affected tooth 36), and group B comprised 35 patients (males 20/57.1%; females 15/42.9%; 36 affected tooth). In group A patients the reattachment was conducted after the trauma, and the direct composite restoration technique was used for patients in group B. All patients were evaluated for complications and pulp status for 5 years. Results There were no significant differences (P > 0.05) in terms of the occurrence of complications observed between groups throughout the 5-year observation period. Conclusion Both methods provide similar results over the 60 months of observation. Clinical Significance Reattachment technique has shown to be a reliable treatment option that might be considered as a primary technique when the fragment is saved after the trauma.
