title: Resolution of fused vertical molar root bridge abutment fracture: report of case.
abstract: Vertical root fractures involving apparently successful endodontic treatment with gutta-percha may be caused by hairline root fractures that existed before root canal therapy was performed. A root stripping technique was used to restore a strategically located tooth in a 70-year-old patient. Bruxism with occlusal trauma is proposed as a significant cause of hairline vertical root fractures. The commonly held view that these fractures arise from root canal condensation techniques appears more circumstantial than factual.
