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.

치아의 완전 탈구는 치조골에서 치아가 완전히 이탈된 것으로 정의되며, 결과적으로 신경혈관 공급의 중단을 야기하는 가장 심각한 치과적 손상 중 하나로 알려져 있다. 완전 탈구는 조직 허혈(tissue ischemia)을 야기하며, 이는 치수 괴사를 초래할 수 있다. 치근단형성술(apexification)은 치수 괴사로 진단된 미성숙 영구치에서 치근단 장벽을 유도하는 전통적인 치료 방법이다. 하지만 치근단형성술로는 치근 길이 및 두께의 증가를 포함하는 치근 발육을 얻을 수 없다. 본 증례는 완전 탈구되어 재식된 이후 치수 괴사로 진단된 치아를 가진 5세 환자에서 ciprofloxacin, metronidazole, cefaclor 및 CollaTape과 Biodentine을 이용하여 시행된 치수재생치료(regenerative endodontic treatment)의 임상적 및 방사선학적 결과를 다루고 있다.
