Managing non-vital immature teeth with open apices is clinically challenging due to the absence of apical constriction and risk of reinfection. Mineral Trioxide Aggregate (MTA) offers a reliable solution, promoting hard tissue formation and providing an effective apical seal. Single-visit apexification with an MTA apical plug offers a time-efficient approach, promoting reliable apical sealing and tissue healing. For esthetic concerns, the walking bleach technique effectively addresses discoloration in non-vital teeth without compromising structure. The combined approach restores both function and appearance, with clinical success attributed to MTA’s antibacterial properties and calcification-inducing potential. This conservative and reproducible protocol provides an efficient strategy for managing open apex cases in contemporary endodontic practice.
