Objective:-To evaluate Bulk fill composite, Biodentine and Zirconomer as intraorifice barrier to prevent coronal microleakage in root canal treated teeth.
Materials and Methods:- Forty single-rooted mandibular premolars were instrumented and obturated by cold lateral compaction technique. The teeth were randomly divided into three experimental groups according to the materials used: Bulk fill composite, Biodentine and Zirconomer (n=10) and two control groups (n=5). In experimental groups, 3 mm of coronal gutta-percha was removed and replaced with the study material. Samples were submerged in Rhodamine-B dye in vacuum for one week. Specimens were longitudinally sectioned and leakage measured using a 10X stereomicroscope and graded for depth of leakage.
Results:- According to the results of the present study, Bulk fill composite demonstrated better seal (P < 0.05) than the other two groups. There was statistical significant (p<0.05) difference between Bulk fill composite and Biodentine and also between Biodentine and Zirconomer. There was highly statistical significant (p<0.001) difference between Bulk fill composite and Zirconomer.
Conclusions:- Using Bulk fill composite as intraorifice barrier, reduced amount of microleakage was seen as compared to biodentine and Zirconomer.
