Abstract
Aim: To evaluate and compare clinically and radiographically the effect of using two different coronal plug materials (NeoMTA versus conventional white MTA) in revascularization of non-vital immature permanent anterior teeth, with special reference to assessment of discoloration potential over time. Methodology: Revascularization procedure was performed in (30) immature permanent non-vital anterior teeth which were randomly allocated to two equal groups (n=15). NeoMTA was used as coronal plug material in group (I), while conventional WMTA was used as a coronal plug material in group (II). All treated teeth were evaluated clinically at 1 week, 1, 3, 12 months and radiographically at 12 months. Results: The overall clinical and radiographic success rate of Groups (I) and (II) at the end of the 12 months follow-up period was 100%. Discoloration was detected in a single tooth (9.1%) in group (I) and three teeth (27.3%) in group (II) but the difference between groups was not statistically significant. Conclusions: Both NeoMTA and WMTA are successful coronal plug materials in revascularization of non-vital immature permanent teeth, achieving 100% successful clinical and radiographic results. NeoMTA is a promising coronal plug material that can be used for revascularization procedures in the esthetic zone as it showed less discoloration potential compared with conventional white MTA, however there was no statistically significant difference between both materials
