Although the majority of the studies reported that the use of root canal sealers increased the fracture resistance of endodontically treated teeth , conflicting evidence was found for the reinforcing effect of resin , glass ionomer , and calcium silicate-based sealers while there was moderate evidence for zinc oxide eugenol-based sealers in favor of no reinforcing effect .
Conclusion On the basis of available evidence , the use of root canal sealer increases the fracture resistance of endodontically treated teeth .
Regarding the comparisons among the sealers , no conclusions could be drawn for the superiority of one sealer type to another .
Objective The purpose of this study was to systematic ally review and critically analyze the published data of in vitro studies testing the effect of root canal sealers on the fracture resistance of endodontically treated teeth .
Fracture resistance of roots obturated with three different materials.
OBJECTIVE The aim of this study was to compare the fracture resistance of roots obturated with different material s. STUDY DESIGN Sixty root canals were instrumented and divided into 4 equal groups ( n = 15 each ) . The root canals in group 1 were filled with AH26 sealer and gutta-percha , in group 2 with Resilon and Epiphany , and in group 3 with Ketac-Endo Aplicap and gutta-percha .  Fifteen root canals had no obturation . The force required to fracture was recorded . The data was analyzed with analysis of variance and Duncan test . RESULTS The mean force of fracture for group 1 was significantly higher than for the other 3 groups ( P < .05 ) . There was significant difference between group 2 and group 3 ( P < .05 ) . Group 2 and group 3 were not significantly different from the control group ( P > .05 ) . CONCLUSION The use of AH26 + gutta-percha increased the fracture resistance of instrumented root canals compared with Resilon + Epiphany and Ketac-Endo Aplicap + gutta-percha
