An old concept revisited - Revascularisation in endodontics - A case report

This study describes the treatment of a necrotic immature permanent central incisor with crown fracture. Instead of the conventional root canal treatment, a regenerative approach based on conservative endodontic method for revascularization was provided. The root canal was gently debrided of necrotic tissue by irrigating with sodium hypochlorite and then medicated with tri-antibiotic paste. After 28 days the sinus tract had healed, and the tooth was asymptomatic. The tooth was accessed, tri-antibiotic paste was removed, bleeding was stimulated to form an intracanal blood clot, and glass-ionomer cement was placed coronal to the blood clot. After 18 months, a progressive increase in the thickness of the dentinal walls and subsequent apical development was seen radiographically suggesting that appropriate biologic response can occur with this type of treatment of the necrotic immature permanent teeth.
