Endodontic retreatment of central incisor with blunderbuss canal and flared root using mineral trioxide aggregate & compo-post (anatomic post) – a case report

Clinicians have traditionally found it difficult to manage the rehabilitation of blunderbuss canals. Mismanagement of flared canals with extensive coronal destruction might result in an adverse fracture of the tooth, which can result in severe failure. To improve fracture resistance, post and core treatments require the reinforcement of such canals. Prefabricated fibre posts have a major disadvantage in that they are unable to adapt to non-rounded, wider canals and are not long-lasting. As a result, such canals are reinforced using contemporary procedures such as specific anatomic posts for optimal stability, fracture resistance, and dentin replacement. The focus of this case study is on endodontic re-treatment utilising MTA (Mineral Trioxide Aggregate) to achieve correct apical seal of open canal, followed by creation of a 'Compo-post' using glass fibre post and composite resin to restore the function as well as aesthetics of the weakened tooth.
