Abstract
Keywords: Apexification, cone beam computed tomography, immature nonvital
teeth, mineral trioxide aggregate, revascularization.
Aim: To evaluate and compare pulp revascularization and apexification in
immature non-vital permanent incisors clinically and radiographically.
Materials and methods: 30 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: 15 teeth were treated with Pulp
revascularization and group II: 15 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. Then the root canal was dried with paper points
and triple antibiotic paste (TAP) was applied and it was removed by saline
irrigation after two weeks. In group I (revascularization) bleeding
enhancement was done and MTA material was applied 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. Results: There were no statistically significant difference between
groups regarding clinical, CBCT (root length and density of deposited tissue)
and radiographic evaluation criteria. There were statistically significant
differences between both groups in CBCT evaluating canal width and
periodontal ligament space. Conclusions: Revascularization and MTA
apexification techniques resemble in all clinical, radiographic and CBCT
criteria except in decreasing of the width of developed canal and periodontal
ligament space in revascularization group.
