Bidirectional spiral and epoxy root-canal cement combined with a single gutta-percha point technique creates a seal equivalent to a lateral condensation and thermoplastic gutta percha. Thoroughly coats walls of root canal and lateral canals without significant cement being forced apically. Reverse spirals on apical end rotate in an unwinding direction out of canal to prevent binding. Unlike thermoplastic techniques, there is no shrinkage upon cooling. Radiopaque for clear X-ray viewing.
