Aim: for evaluation and comparison of pulp revascularization and apexification in immature non-vital permanent incisors by CBCT.
. Material and methods: 15 immature permanent incisors of children (7-9 years old) had irreversible pulpitis or necrotic pulp were selected and randomly divided into 2 groups; Group I: 7 teeth were treated with Pulp revascularization and group II: 7 teeth were treated with MTA apexification. Each tooth was completely isolated with a rubber dam then access opening was done. Irrigation of the pulp chamber with 2.5% NaOCl then sterile saline and water. The root canal was then dried with paper points, triple antibiotic paste (TAP) was administered, and it was removed two weeks later with saline irrigation. In group I (revascularization) bleeding enhancement was done and MTA material was performed over the formed blood clot while in group II (apexification) the whole root canal space was filled with MTA. Finally, pulp chamber was filled with GIC filling in both groups. Conclusions: Both groups are resemble in all CBCT criteria except in dentin volume and root length in mesiodistal direction which significant in Revascularization group.
