Abstract
Regenerative endodontic procedures provide new hope of converting nonvital tooth into vital once again. These potential regenerative approaches include root canal revascularization, postnatal stem-cell therapy, pulp implant, scaffold implant, three-dimensional cell printing, injectable scaffolds, and gene therapy. In this article, we describe successful revascularization treatment of necrotic permanent premolar tooth. Clinical and radiographic examination showed pulp involvement due to deep pit defect and periapical infection. Examination findings suggested revascularization treatment which was started with irrigation of canals using 1.25% of sodium hypochlorite and saline, followed by placement of 3-week dressing of triple antibiotic paste (ciprofloxacin, metronidazole, and minocycline). After removal of triple antibiotic paste blood clot was induced and mineral trioxide aggregate was placed on the blood clot followed by sealing the canal with glass ionomer cement. During radiographic and clinical follow-ups, the patient was asymptomatic and periapical lesion was healed, roots continued to develop, and root apex maturogenesis was complete.
