Marisha Bhandari, Vineeta Nikhil, Sheetal Grover, Shikha Jaiswal, Nidhi Srivastava

Aim – The aim and objective of the ex vivo study is, to assess fracture resistance of single rooted teeth filled using the Real Seal adhesive system and ActiV GP single-cone technique and to compare these results with those obtained using the conventional gutta-percha cone and AH-plus sealer with using cold lateral compaction technique. Methodology – Sixty freshly extracted human mandibular premolar teeth with similar dimensions were selected, which was decoronated at the cemento-enamel junction, and length of the roots was adjusted to 12 mm. The specimens were randomly divided into five groups. The biomechanical preparation was done using Brasseler Endo Sequence rotary file system upto the file # 35 and copious irrigation was done using 2 ml of 5.25% NaOCl followed by 2 ml of EDTA and final irrigation done using distilled water, following each instrumentation . The teeth in each group were obturated as follows: Group 1; AH-plus sealer and gutta-percha cone (Cold lateral compaction), Group 2; Epiphany sealer and Resilon cone (Cold lateral compaction), Group 3; ActiV GP cone and Endo Sequence BC sealer (Single cone), Group 4; Positive control group, Group 5; Negative control group. After the sealers had set, the specimen were embedded in acrylic moulds and subjected to a compressive loading in the universal testing machine. Results – The load at which complete fracture occurred was recorded and statistically analysis done using ANOVA one-way analysis of variance and unpaired t-test. The statistical analysis concluded that the fracture resistance Group 5 showed highest fracture resistance followed by Group 1, Group2, Group 3 and Group 4 showed the least fracture resistance. Fracture resistance in decreasing order: Group 5 > Group 1 > Group 2 > Group 3 > Group 4
Conclusion : Obturation  with  Gutta-percha  and  AH-plus  sealer  gives  a significantly high fracture resistance as compared to Resilon with Epiphany  sealer  and  ActiV  GP  with  Endo Sequence  BC  sealer.
