Features of clinical course of apical periodontitis of permanent teeth with disorders of root formation as a result of injury

Abstract

Prevalence of trauma of permanent teeth is 13% - 17,4%. Injuries teeth occur most often in children. Pulp necrosis occurs in 34.2% of injured teeth. It promotes the growth and multiplication of opportunistic microorganisms in the root canal system. The action of toxins and products of vital activity of these microorganisms cause damage to the periapical tissues, and in teeth with incomplete root formation often lead to a stop of root development. The high prevalence of post-traumatic periodontitis stipulate the importance of their timely clinical and radiological diagnosis.
