Use of bioactive materials and limited fov cbct in the treatment of a replanted permanent tooth affected by inflammatory external root resorption: a case report

BACKGROUND:Inflammatory external root resorption is one of the possible complications of replantation of an avulsed tooth. Several studies have shown that limited FOV CBCT is an efficient diagnostic support and in treatment planning of these cases in paediatric patients because of its high resolution combined with low radiation doses. The recent literature has suggested that Biodentine is an effective material for resolution of inflammatory root resorption. CASE REPORT:This article describes the successful therapy of a replanted tooth affected by inflammatory root resorption. In the present case, a CBCT exam was performed to detect the extent of the damage, and the canal was filled with Biodentine in the apical third. At present, the threated tooth is asymptomatic, and the twelve months follow-up examination showed healing of periradicular hard tissues.
