An in-vitro: Comparative evaluation of apical leakage in roots filled with resilon and epiphany self-etch sealers using cold lateral condensation and warm vertical condensation techniques

Aim: This in-vitro study was conducted with an aim to compare apical leakage between root canals filled with Resilon/Epiphany self-etch (SE) system, by using cold lateral condensation and warm vertical condensation obturation techniques. Materials and Methods: A total of 80 recently extracted human mandibular permanent premolars with straight roots with single canals were used in this study. Of 80 samples, 40 were randomly divided into two experimental groups of 20 teeth each ( n = 20). Samples in Group I were obturated with cold lateral condensation technique using Resilon/Epiphany SE sealer, in Group II were obturated with warm vertical condensation using Resilon and Epiphany SE sealer. 40 teeth saved as controls 20 positive ( n = 20) and 20 negative ( n = 20). Results: This in-vitro study showed statistically significant difference between sealing ability of two techniques. Conclusion: Warm vertical condensation obturation technique was better with less apical dye penetration.
