From: Pulp regeneration with hemostatic matrices as a scaffold in an immature tooth minipig model
Representative radiographic and histologic images of the fibrin-based matrix scaffold (FM) group. Regenerative endodontic procedures were performed, involving FM application after bleeding induction, followed by MTA capping and glass ionomer restoration. Periapical radiographs were taken preoperatively and 4 and 12 weeks after treatment (A,B, and C, respectively). Internal root resorption (arrowhead) and periapical radiolucency in both roots were observed (white line square, C). After 12 weeks, the teeth were retrieved and processed for histologic analysis. Full images of the tooth (indicated in the left periapical radiograph) (D). Mesial root showing an irregularly obliterated root with newly deposited mineralized tissue without an odontoblastic layer (E), while the distal root showed a resorptive lesion with inflammatory cell infiltration (F).
