This case report describes the Revascularization of a Permanent Immature Mandibular Premolar with Pulp Necrosis and apical periodontitis. Access opening was done & the canal was disinfected with copious irrigation using 2.5% NaOCl and triple antibiotic paste (Ciprofloxacin, Metronidazole, and Minocycline) as intracanal medicament. After the disinfection protocol is complete, it is followed by revascularization procedure. The apex was mechanically irritated to initiate bleeding into the canal to produce a blood clot to the level just below the level of cementoenamel junction. Mineral trioxide aggregate was placed over the blood clot followed by bonded resin restoration above it. After one year follow up; the patient was asymptomatic, no sinus tract was evident. Apical periodontitis was resolved, and there was radiographic evidence of continuing thickness of dentinal walls.
