Abstract

Background and objectives: The success of root canal therapy hinges on achieving a tightly sealed closure at the apical end of the root canal. This study aimed to compare the sealing effectiveness of root canal obturation using various materials for obturating cones and sealers.

Material and methods: This experimental in vitro study conducted from June 2022 to June 2023 in the Duhok city in the medical lab of collage of medicine. Ninety extracted human single canal premolars were used, prepared by wave one gold medium size file (35/0.06), irrigated by 2.5% sodium hypochlorite. Divided into six groups, three of obturating cone, two carrier-based (GuttaCore and Thermafil) and one conventional gutta-percha. These groups were further subdivided into 15 teeth each, distinguished by the sealers used: Ceraseal (MetaBiomed Co., Cheongju, Korea) and AH Plus (epoxy resin-based sealer).

Results: Comparing types of obturating cone and sealers, the sealing ability of Ceraseal sealer with guttaCore is (26.77), with better sealing ability of thermafil (12.10) and with conventional gutta-percha (30.15) with p-value of <0.001. while the sealing ability of AH plus with guttaCore is (33.73), with thermafil (20,07) and with good sealing ability of conventional gutta-percha is (15.20) with p-value <0.001. The difference is significant for both groups.

Conclusion: The sealing ability of the materials used to regard obturating cone and sealers were not able to fill the root canal completely without leaving gabs. Thermafill gutta-percha with Ceraseal sealer had a maximum area of root canal filled.
