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.
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 standardized preparation and remaining ten teeth were served as negative control. Then teeth were randomly assigned into different groups depending on sealer used for obturation as follows:
Negative control—no instrumentation was performed.
Positive control—gutta-percha with out the use of any sealer.
Experimental group—gutta-percha and Tubli-Seal EWT root canal sealer.
Experimental group—gutta-percha and AH Plus.
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.
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 materials tested. There was no statistically significant difference among experimental groups.
Epiphany SE sealer/Epiphany points demonstrated highest fracture resistance values than the other materials tested and intact tooth had highest resistance against vertical root fracture.
Epiphany SE sealer/Epiphany points may be one of the materials of choice in the endodontic treatment of teeth.
