AbstractThe success of modern endodontic therapy relies heavily on the ability to thoroughly clean, shape, disinfect, and obturate the root canal space. Among these, obturation has undergone the most significant evolution over the past few decades. “Contemporary obturation” reflects a paradigm shift from traditional gutta-percha based cold lateral condensation to advanced materials, improved sealer chemistry, bioceramics, hydraulics, warm vertical compaction, carrier based technologies, and injectable obturation systems. This article provides a comprehensive review of present day obturation philosophies, materials, and techniques. It integrates current evidence on the biological rationale for three dimensional obturation, the limitations of legacy methods, advancements in gutta-percha formulations, bioactive sealers, and the trend toward single cone hydraulics supported by minimally invasive endodontics (MIE). Emerging materials such as bioceramic coated cones, resin sealers, injectable bioceramic pastes, and obturation using 3D thermoplasticized carrier systems are evaluated. The review also discusses technological integration, including cone-beam computed tomography (CBCT) assisted diagnosis, enhanced canal shaping using NiTi rotary systems, and their implications for obturation selection. Comparative outcomes, advantages, disadvantages, and clinical considerations are included to provide a comprehensive understanding of contemporary obturation protocols. The article concludes by presenting future directions, including fully bioactive obturation systems, guided obturation, and nanotechnology driven solutions.
