Introduction: Endodontic treatment may be required for the permanent teeth due to different reasons in childhood. Biological materials such as MTA and tricalcium silicate-based (Biodentine®, Septodont, France) bioceramic repair material have started to be used nowadays in different endodontic treatment. Studies have shown that these materials stimulated the formation of new vascularized tissue in the apical of mature teeth with necrotic pulp and with periapical lesions. In addition, MTA and tricalcium silicate-based (Biodentine®, Septodont, France) bioceramic repair material are preferred in direct and indirect pulp capping due to their properties such as biocompatibility and impermeability. Purpose: The aim of this study is to examine the teeth clinically and radiologically after the use of tricalcium silicate-based (Biodentine®, Septodont, France) bioceramic repair material and MTA as a barrier on the pulp capping, Cvek pulpotomy and regenerative endodontic treatment. Case Description: Different endodontic procedures using MTA and Biodentine in pediatric patients with different endodontic treatment needs are shown with 4 cases. Conclusion: Today, the success rate is high in vital pulp treatments with newly developed materials such as MTA and tricalcium silicate-based (Biodentine®, Septodont, France) bioceramic repair material In addition, root development continues after regenerative endodontic treatments with Mineral Trioxide Aggregate (MTA) or tricalcium silicate-based (Biodentine®, Septodont, France) bioceramic repair material in non-vital and open-apex teeth.
