Pulp Revascularization Versus MTA Apexification

A Comparative Study Between Pulp Revascularization and MTA Apexification in Necrotic Immature Anterior Teeth, A Randomized Controlled Trial

This study compared the efficiency of pulp revascularization and MTA apexification in the treatment of patients with necrotic immature anterior teeth.

the participants with 66 anterior necrotic immature teeth were randomly assigned into two equal groups with 33 teeth per each, according to regeneration and MTA apexification. At the first visit, all teeth were accessed and irrigated with NaOCl then a TAP was applied as intra-appointment intracanal medication. At the second visit, after removal of the medication with the irrigation, bleeding was initiated into the canal and isolated by the MTA in the orifice in the regeneration group. While in the Apexification group, the MTA was packed apically and all teeth were finally restored with resin composite restorations. The patients were recalled after 1, 3, 6, and 9 months for clinical and radiographic follow up.

Inclusion Criteria:

• Medically-free patients having immature necrotic anterior teeth (with or without apical periodontitis/abscess) even with previous intervention.

Exclusion Criteria:

• History of allergy to any of the antibiotics in the tri-mix used in the study
• Patients with systemic diseases e.g. Diabetes mellitus, bleeding disorders,…
• Psychological disturbance
• External / internal root resorption or cystic lesion.
