Horizontal/oblique root fractures in the palatal root of maxillary molars with associated periodontal destruction: case reports.

AIM: To report two cases of palatal root fracture in maxillary molars that were successfully managed in the short term by root canal treatment and root amputation. SUMMARY: In the first case, a 48-year-old woman with bony destruction and a deep periodontal pocket on the palatal root of tooth 26 (FDI) underwent root canal treatment. Bleeding into the palatal canal and radiolucent lines over the root suggested a fracture. Further evidence was provided by an electronic apex locator. Subsequent surgery confirmed the presence of a horizontal root fracture and the fractured root was removed. In the second case, a 75-year-old woman presented with pain from the left posterior teeth. Clinical examination revealed an oblique root fracture of tooth 27 palatal roots with abscess formation and a deep periodontal pocket. Palatal root amputation and odontoplasty were performed. This was followed by root canal treatment. Both teeth were preserved in the short term and early healing of these two cases was uneventful. KEY LEARNING POINTS: Horizontal/oblique root fracture of the palatal root in molars is rare. A combination of periodontal and root canal treatment and palatal root amputation may allow short-term preservation of functional teeth.
