Abstract
When the pulp becomes necrotic and infected due to the trauma, the bacterial toxins and byproducts can penetrate through dentinal tubules and initiate an inflammatory response in the periodontal ligament causing bone loss, apical periodontitis and external resorption. Disinfection and adequate root filling have been shown to be the treatment of choice when such conditions are present. Different bioceramic materials are been used to achieve a tight seal in the apical portion which may lead to healing.
