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 .
A comparative evaluation of the vertical root fracture resistance of endodontically treated teeth using different root canal sealers: an in vitro study.
OBJECTIVE The objective of this study is to evaluate the vertical root fracture resistance of endodontically treated teeth obturated with - Tubli-Seal EWT/Gutta-percha , AH Plus/Gutta-percha , Epiphany SE sealer/Epiphany point . STUDY DESIGN Sixty-five single rooted premolars were decoronated and root length was 14 mm for each specimen . Fifty five teeth were enlarged up to ISO size 40 master apical file with stainless steel K-files using st and ardized preparation and remaining ten teeth were served as negative control . Then teeth were r and omly assigned into different groups depending on sealer used for obturation as follows : Group 1 : Negative control-no instrumentation was performed . Group 2 : Positive control-gutta-percha with out the use of any sealer . Group 3 : Experimental group-gutta-percha and Tubli-Seal EWT root canal sealer . Group 4 : Experimental group-gutta-percha and AH Plus . Group 5 : Experimental group-epiphany SE sealer and epiphany points . After 72 hours , the specimens were embedded in autopolymerizing resin leaving 7 mm of each root exposed and were subjected to fracture testing under universal testing machine at a crosshead speed of 1.0 mm per minute until the root fractured . Results were statistically analyzed using one-way ANOVA and independent t-test . RESULTS Showed that Epiphany SE sealer/Epiphany points showed highest mean fracture resistance and Tubli-Seal EWT group showed the least fracture resistance of all the material s tested . There was no statistically significant difference among experimental groups . CONCLUSION Epiphany SE sealer/Epiphany points demonstrated highest fracture resistance values than the other material s tested and intact tooth had highest resistance against vertical root fracture . CLINICAL SIGNIFICANCE Epiphany SE sealer/Epiphany points may be one of the material s of choice in the endodontic treatment of teeth
