Rehabilitation to crown-root fracture by fragment reattachment with resin-modified glass ionomer cement and composite resin restoration

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

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.

Conservative Treatment of a Complicated Crown-root Fracture Using Adhesive Fragment Reattachment and Composite Resin Restoration: Two Year Follow-up

Crown-root fracture is one of the most challenging fracture types in the dental traumatology literature. Traumatized anterior teeth require quick functional and esthetic repair. In the case of a complex crown fracture of the maxillary left central incisor, requiring endodontic treatment, a fiber-reinforced post was used to create a central support stump to restore the dental morphology. This report describes the clinical procedures involved in the treatment. After two years of follow-up, the clinical and radiographic findings demonstrated that the adopted clinical protocol was successful and yielded healthy periodontal tissues with no signs of periradicular pathology.
