Revascularization of an Immature Necrotic Mandibular Second Molar Using Calcium Hydroxide: A 3-year Follow Up

Endodontic intervention in necrotic immature permanent teeth is usually a clinical challenge. With appropriate case selection and optimal disinfection, regenerative endodontic procedure (REP) can be effective and a desirable result can be obtained. In this report, an immature necrotic mandibular second molar had been treated by REP in two visits. In the first visit, a nonsetting calcium hydroxide was used as intracanal medication after irrigation with 1.5% (NaOCl). In the second visit, blood clots were created in the root canals. MTA was placed over the blood clots and the tooth was restored with a composite filling and stainless-steel crown. A clinical and radiographic follow up was performed for three years where the tooth was deemed a symptomatic with a complete root formation.
