Canal Projection - A Technique for the Management of Badly MutilatedÂ·Teeth: Case Reports
Isolating a severely broken down tooth is a considerable challenge. Due to insufficient tooth structure either the rubber dam placement becomes difficult or the dam leaks. Coronal bonded build-up can simplify the endodontic phase and strengthen the tooth, decreasing the possibility of further damage to the tooth due to the rubber dam clamp or mastication. The canal projection technique allows for isolation of the individual canals bringing them to the cavosurface margin. This offers adequate visualization and convenience for instrumentation as straightline access is achieved and also provides a strong core and coronal seal of the operative field. In these case reports management of badly broken down teeth was done by canal projection technique using plastic delivering tips and hypodermic needles as projectors. Composite core build up was done,which helped in rubber dam placement.
