Introduction:
Invasive cervical resorption (ICR) may occur as a consequence of trauma, orthodontic treatment, intracoronal bleaching, and surgical procedures and may lead to the progressive and destructive loss of tooth structure. The restoration of these resorptive defects is a challenging task because no single restorative material possesses good sealing ability, reinforcement of remaining tooth structure, and biocompatibility simultaneously.
Methods:
This case presented with invasive cervical resorption class 2 (Heithersay) and apical inflammatory resorption caused by trauma in tooth #9. The surgical management of ICR was performed, and, finally, the roots were externally reinforced by filling the resorptive defect with a combination of composite and resin-modified glass ionomer cement, proposed as reverse sandwich restoration (RSR).
Results:
This novel RSR was well tolerated by the periodontal tissues. A follow-up x-ray showed no pathological changes and no recurrence of resorption.
Conclusions:
This case report presents a treatment strategy for root reinforcement that might improve the healing outcomes for patients with invasive cervical resorption.
