Premixed Bioceramic Putty as an Apical Plug in Immature Anterior Permanent Teeth

Comparative Evaluation of Premixed Bioceramic Putty Versus MTA as Apical Plugs in Nonvital Immature Anterior Teeth: A Clinical Randomized Controlled Trial

Following the randomization procedure, children will be divided into 2 groups (25 immature anterior permanent incisors in each group): Group I will be treated with MTA as apical plug while group II will be treated with Premixed Bioceramic Putty as apical plug. After working length determination, instrumentation, and irrigation of the root canals, apical plug will be done. in MTA Group, MTA will be placed into the apical 4 mm of root canals, then a moist cotton pellet will be placed and the access cavity will be restored with glass-ionomer-based restoration. Next day, glass-ionomer-based restoration and the cotton pellet will be removed, then the coronal restoration will be completed with GIC, composite. In the Premixed Bioceramic Putty group, Well-Root™ PT will be placed into the apical 4 mm of the canals. After 12 min, the coronal and middle third of the root canal will be filled with gutta-percha. The coronal restoration will be completed with GIC, composite.

children will be recalled for clinical and radiographical follow-up after 6 and12 months after treatment.
