title: Restoration of the anterior maxilla after thermal trauma as a sequela to post removal: a clinical report.
abstract: Removing posts from endodontically treated teeth without considering the effects of heat trauma can have adverse consequences for the tissues surrounding the roots of the associated teeth. Ultrasonic instrumentation has been widely used as a more conservative approach than other methods of removing posts without untoward sequelae. However, copious irrigation must be used to prevent elevated temperatures caused by ultrasonic energy. This clinical report presents the consequences of post removal in 2 maxillary incisors with ultrasonic instrumentation without sufficient regard to root overheating. Necrosis of the surrounding tissues was observed after 2 weeks. The functional and esthetic reconstruction of the area affected by the heat trauma is described.
