Two Distinct Prognoses for Symmetrical Immature Central Incisors Following Lateral Luxation

Lateral luxation of permanent teeth is a common injury, and the most frequent post-injury complications is Pulp Canal Obliteration (PCO) followed by pulp necrosis and root resorption. This report presents two different prognoses for symmetrical immature maxillary central incisors after lateral luxation in a 7-year-old boy. Both teeth were laterally luxated and the gingiva distal to the left incisor was lacerated. Under local anesthesia, the involved teeth were repositioned and stabilized. At the 8 months follow-up, both teeth were without clinical symptoms. The left incisor exhibited a wide root canal space and thinner of the walls from radiograph. However, the right incisor had partial PCO that progressed to total PCO 9 months later. PCO might have been related to injury of the neurovascular supply of the pulp. The thinner of the root canal walls of the left incisor might due to the severe injuries of the peridontal ligament and the dental papilla.
