Abstract
Aim: To evaluate the clinical and radiographic performance of the effectiveness of Calcium Hydroxide as intracanal medication in revascularization of immature teeth with necrotic pulp. Methodology: Regenerative endodontic treatment was performed in (56) immature necrotic anterior permanent teeth which were randomly allocated to two equal groups. Calcium Hydroxide intracanal medication was used at the end of the first visit in group I, while bi-antibiotic paste intracanal medication was used in group II. After resolution of the clinical signs and symptoms in the second visit, mineral trioxide aggregate was placed as coronal plug in both groups following blood clot formation. All the treated teeth were evaluated clinically and radiographically at 3, 6, 9, and 12 months of time interval using predetermined criteria. Results: Dental trauma was the most common etiological factor causing pulp necrosis of teeth enrolled in this study. Maxillary teeth were affected more by dental trauma with maxillary central incisors being the most commonly involved teeth. The overall clinical and radiographic success rate of Groups I and II at the end of the 12 months follow-up period was 92% and 100% respectively and there was no statistically significant difference between the two groups (P-value equal to 0.157). Regenerative endodontic treatment could result in partial or total canal obliteration
