Comparative Evaluation of Different Intra-orifice Barriers on the Microleakage of Endodontically Treated Roots Obturated with Gutta-percha “An In-vitro Study”

Aim: To comparatively evaluate various Intra-Orifice barriers (IOB) namely; Cention N (Ivoclar Vivadent), Biodentine (Septodont), Light Cured GIC (GC Gold Label 2LC) and Tetric Flow Vivadent) for their effects on the microleakage of endodontically treated teeth.
 Study Design: In-vitro study.
 Place Study: Department Endodontics conservative dentistry, Himachal dental college, Sundarnagar, Pradesh.
 Materials Methods: Seventy-five mandibular premolars were decoronated to a standardized length, prepared obturated with Gutta-Percha AH Plus sealer. Except control specimens, coronal 3-mm gutta-percha was removed filled different Intra-orifice barrier materials. The specimens (75) divided into five groups (n = 15) basis material used. Group 1: Control, 2: N, 3: Biodentine, 4: GIC, 5: Flow. In experimental groups, 3 mm replaced study material. Samples submerged in 2% methylene blue dye vacuum one week. Specimens longitudinally sectioned leakage measured using 50X stereomicroscope graded depth leakage.
 Results: present roots significantly affected by type used following pattern observed: > >Light N>Control.
 Conclusion: concluded that placement provides better seal, prevents microleakage, enhance longevity postobturation restorations, proved be best followed Control group.
