Posttraumatic External Apical Root Resorption - Case and Treatment Report

Teeth trauma in the developmental age is the second reason as for the frequency of patients' reporting to the stomatology doctor. The traumas in the form of the complete tooth dislocation are frequent with the 0.5-16% children with permanent teeth and are more often common with boys. The dislocated teeth are most usually the medial incisor in the jaw and more rarely - in the mandible. External tooth root resorption is a complication occurring with tooth trauma which, in consequence, leads to the damage of the periodontal tissues. The problem prevails in teeth which are completely dislocated, secondarily implanted. The process depends on the preservation of pulp vitality. Etiology and pathogenesis of the external resorption is not fully explained. In this study, the authors described a case of a 10 year-old patient, who in the consequence of the trauma in 2005, experienced complete dislocation of tooth 21. The tooth was replanted without a parallel endodontic treatment. In the course of the control study, in the period of 3 years from the trauma, the vitality of the pulp was certified. In 2008, after 3 years from the trauma the beginnings of complications in the form of the chronic purulent inflammation of periapical tissues - the external resorption of the tooth root was recognized and described radiologically. The study presents clinical possibilities of inhibiting of the above described pathological process with the use of hydroxide-calcium preparations and curative powers of ozone therapy.
