A seven-year-old male patient presented with a localized buccal swelling apically on tooth #21 and with a radiographic app. One week earlier, the patient had suffered an uncomplicated crown fracture, and the referral dentist had solely performed a permanent restoration by rebonding the fracture fragment of the crown. The diagnosis was pulp necrosis, and a regenerative endodontic procedure was decided due to the wide-open apex of the injured tooth. After access cavity preparation was performed, it was evident that no degeneration of the pulp had occurred, so the tissue was removed using a sterile barbed broach and processed for histopathologic examination. A whitish tissue specimen of soft consistency, 0.8 cm in length and 5 μm thick, was processed for histologic evaluation. An extensive coagulative necrosis of the pulp tissue was revealed with dense aggregates of neutrophils along with areas of abscess formation.
