Research Abstract

The adhesive root canal filling materials influence on the behavior of vertical root fractures (VRFs). The decrease of dentin by the root end resection and cavity preparation did not bring a susceptibility of VRFs. The propagation of fracture line in VRFs could be observed by thermal cycling procedures. It is suggested that the adhesive root canal filling materials did not prevent the propagation of fracture line in VRFs. It is important on clinical option to choice the adhesive root canal filling materials.
