D.T. LIGHT-POST ILLUSION® X-RO® are dental posts used for reconstruction of devitalized teeth. They are made of X-RO yellow translucent fibers bound in a colored resin Epoxy-vinyl ester matrix, which becomes translucent in the mouth. The post color will re-appear on command under cold air, water spray if re-treatment is required. D.T. LIGHT-POST® drills (UNIVERSAL/FINISHING) are intended for mechanical shaping and cleaning of the root canal.
