Treatment of paraesthesia following root canal treatment by intentional tooth replantation : a review of the literature and a case report

BACKGROUND: Some endodontic procedures may cause damage to the inferior alveolar nerve, leading to paraesthesia. When such complication is due to extrusion of obturation material beyond the apex, it can be managed by intentional replantation (IR). IR consists of the removal of a tooth and its re-insertion into the socket after performing a proper root end manipulation. It is a relatively conservative procedure aimed at preserving the tooth and, with correct case selection, can provide a predictable outcome. AIMS: The aim of the present paper is to report a case of paraesthesia following endodontic treatment of second mandibular molar successfully treated by intentional replantation. RESULTS AND CONCLUSION: In our opinion this treatment modality may be considered when the extrusion of root canal filling material causes irritation to the periapical tissues and endodontic retreatment is unfeasible.
