Abstract

Dental avulsion, defined as the complete displacement of a tooth from the alveolar bone with consequent loss of the blood and nerve supply, was reported as one of the most severe dental injuries. Avulsion can cause tissue ischemia, which leads to pulp necrosis. Apexification is a conventional treatment method that induces an apical calcified barrier in immature roots with pulp necrosis. However, root development characterized by an increase in the root thickness and length cannot be achieved by apexification. The purpose of this case report was to describe the radiographic and clinical outcomes of regenerative endodontic treatment for the avulsed and necrosed permanent tooth with an immature root after replantation in a 5-year-old girl; the treatment was performed using a mixture of ciprofloxacin, metronidazole and cefaclor, CollaTape and Biodentine.
