Influence of state of complex load on endurance of teeth strengthened by endodontic post systems

The purpose of this study was to determine the fracture load for teeth strengthened by different endodontic post system. The endurance of teeth was tested under conditions of complex load. For the tests, canine teeth extracted due to orthodontic or periodonthopatic reasons were examined. The samples were prepared in three separate groups: teeth filled with Endomethasone paste (without endodontic post), teeth strengthened by standard endodontic post systems, teeth strengthened by individual endodontic post systems (casted).
