Regenerative Endodontic Treatment With Blood Clot and PRF: a Clinical Report

Objectives: Blood clot (BC) and platelet-rich fibrin (PRF) have been used as scaffolds in regenerative endodontic treatment (RET). The aim was to compare the performance of PRF with BC in inducing root development after RET of two traumatized immature necrotic permanent teeth of a patient.
Methods: A 6 year-old boy with trauma to maxillary central incisors applied to pediatric dentistry clinic. Clinical and radiographic examinations revealed both incisors having necrotic pulp without apical periodontitis. In the first appointment both teeth were treated by preparing access cavities and pulp removal. The canal was irrigated with 1.5 % NaOCl. Calcium hydroxide was inserted into the canal for 3 weeks.
At the second appointment, both canals were irrigated with EDTA. Blood was drawn from the patient’s forearm for preparation of PRF. After provoking periapical bleeding, the PRF was placed into the canal space of maxillary right central incisor while blood clot alone to the maxillary left central incisor. Mineral trioxide aggregate was placed directly over the PRF and blood clot. Teeth were temporarily restored with glass ionomer cement. Two weeks later, both teeth were permanently restored with composite resin. The patient was followed-up for 28-months, clinically and radiographically.
Results: After 28 months clinical examination revealed no sensitivity to percussion or palpation tests in both teeth. Root elongation, dentinal wall thickening and continued apical closure in both teeth were observed in radiographs. Cone-beam computed tomography images revealed that tooth treated with BC showed narrower root canal in the apical region and tendency for root obliteration compared to tooth treated with PRF.
Conclusions: Both PRF and BC exhibited successful clinical outcomes and continued root canal development in the regenerative endodontic treatment. Nevertheless, PRF may be potentially an ideal scaffold compared to BC in terms of long-term pulp obliteration.
