In the case presented by Jethi et al., a single-rooted premolar with two separate canals formed a classic “bayonet” (S-shaped) radicular configuration.
The double curvature significantly increases the risk of iatrogenic complications such as instrument separation, ledges, or canal blockage during canal negotiation, instrumentation, and obturation.
This report describes a carefully executed post-endodontic reinforcement of such a premolar — before crown placement — using a novel technique aimed at preserving both structural integrity and functional longevity.
Through precise diagnosis, meticulous canal negotiation and obturation, and thoughtful restorative planning, the authors demonstrate how even a “challenging” bayonet-shaped root canal anatomy can be successfully managed, offering a valuable reference for clinicians facing similar anatomical variants.
