Effect of Different Sealer Systems on the Resistance to Vertical-Root-Fracture of Endodontically Treated Tooth

An unfavorable complication of root canal is vertical root fracture. The aim of present study is to evaluate the vertical root fracture of treated teeth filled with gutta percha and Resilon obturating material using different sealers. Forty mandibular premolars used in the study. Canals randomly divided into four groups (n=10). Group-A eugenol-based (Endofill) sealer with gutta percha, Group-B epoxy-amine (AH Plus) sealer with gutta percha, Group-C resin-based (Real Seal) sealer with Resilon, or Group-D epoxide-based (Perma Evolution) sealer with gutta percha. Roots mounted vertically in cold cure acrylic blocks and subjected to vertical loading with a crosshead speed of 1mm min. The point at which fracture of the roots occurred recorded in Newton. Roots obturated with gutta percha and epoxide sealer show the highest resistance to vertical fracture (pless than0.05). While, roots obturated with gutta percha and eugenol sealer revealed the lowest vertical fracture resistance value compare to other groups
