Management of Recurrent Traumatic Crown-Root Fracture in a Permanent Incisor Using Fragment Reattachment: A 3-Year Follow-Up Case Report

Traumatic Dental Injuries are most common in children and adolescents of 11 to 18-years-old age range and usually associated with sports activities, falls and bicycle accidents. A 12-year-old male presented to the Department of Pediatric and Preventive Dentistry, Centre for Dental Education and Research (CDER), AIIMS with pain and loose tooth in the upper front region of jaw since 2 days. Upon radiographic examination a fracture line was revealed at the cervical region of the tooth involving the root. As per IADT (2020) guidelines splinting was performed to stabilize the mobile tooth in the anterior region. Soon the patient had second episode of trauma to the same tooth and upon observation the fragment was re-fractured. So, the root canal treatment was done on the 2nd visit and planned for re-enforced fiber post with fragment re-reattachment. Upon observation oblique fracture line was anticipated at the cervical region and portion of fracture line on the palatal aspect was exposed using a diode laser followed by hemostasis with gauge piece and fiber post insertion was done. The patient was recalled for regular follow-up. Three-year follow-up radiograph revealed continuum in the fractured fragment site, retention of the attached fragment and better healing of surrounding tissues with no pocket depth and bleeding from sulcus.
