Therapeutic Efficacy of Platelet-Rich Fibrin in Delayed Replantation of an Avulsed Tooth: A Clinical Case Report on Management and Outcome Assessment.

This case report describes the successful management of a delayed replantation of an avulsed maxillary central incisor with prolonged extraoral dry time (>60 minutes). A 24-year-old patient presented with a dehydrated avulsed tooth, which underwent extraoral root canal treatment and replantation using platelet-rich fibrin (PRF) to enhance healing. The tooth was splinted for four weeks, and the patient was followed up for two years. The replanted tooth remained asymptomatic, stable, and showed no signs of resorption or infection. This case highlights the importance of a multidisciplinary approach, integrating advanced biological and clinical techniques, in achieving favourable outcomes in traumatic dental injuries.
