Fracture Resistance of Wide Canalled Endodontically Treated Teeth Restored with Different Fiber Post Systems with & without Accessories

Abstract

Within limitations of this study must be recognized. A continually increasing load applied to the teeth is not the type of loading that occurs in the natural oral environment. For that reason, the results of this study should be carefully interpreted. It is necessary to emphasize that this study evaluated an extreme condition of root weakness. Therefore, with regard to a root with loss of dentin structure, the clinician should evaluate the degree of the flared root before condemning it to extraction by taking into account the chance of success with restorative Rehabilitation of flared roots 237 treatment by reconstructing the tooth with adhesive materials in order to maintain the functioning tooth in the mouth. According to the results of this study, it may be concluded that the use of glass fiber posts associated with composite resin or accessory fiber glass posts seems to be an effective method to improve fracture resistance and increase repairable failures on flared root canals. However, additional studies are necessary to clarify which are the best techniques and materials to closely mimic tooth structures, as well as to recover the mechanical properties and resistance to fracture of structurally compromised teeth by flared canals.
