A NOVEL APPROACH IN THE TREATMENT OF HORIZONTAL ROOT FRACTURE USING K-FILE WITH MTA AS AN INTRA-RADICULAR SPLINT

Background: Root fractures in permanent teeth are relatively rare and present complex healing processes, occurring more frequently in children. Mineral trioxide aggregate (MTA) is an endodontic material that offers significant advantages over traditional materials used in fracture repair.It is the first restorative substance known to consistently support the formation of cementum and may also aid in the regeneration of the periodontal ligament. Case Description: This report details the endodontic treatment of a horizontally fractured upper left lateral incisor using MTA combined with an intraradicular splinting technique. After repositioning the fractured segments, the tooth was stabilized internally using a K-file and MTA as the sealing material. This case illustrates that MTA, along with intraradicular splinting, is an effective method for managing horizontally fractured teeth. Follow up:At the six month follow up,the tooth remained asymptomatic. Clinical and radiographic evaluations indicated excellent healing outcomes. Conclusion: MTA demonstrates strong potential as a definitive root filling material for horizontal root fractures due to its superior biological compatibility and physical characteristics.
