Abstract

Objective. The purpose of the present study is to evaluate the sealing ability of synchronized hydraulic condensation and BC Sealer cement in both ribbon-shaped and round root canal systems, and compare it to traditional warm vertical condensation technique with AH Plus. Background. Recently, Brassler USA, introduced a new philosophy for filling root canals termed “synchronized hydraulic condensation.” This method utilizes a bioceramic, aluminum-free sealer (BC Sealer) consisting of a cement-like paste that is able to be injected into the root canal requiring water to set and harden. Little has been reported as to the sealing ability of this sealer and technique. Methods. Forty-eight single rooted teeth were collected and decoronated at 17 mm. They were shaped using EndoSequence rotary instrumentation to a size of 30/.04 and cleansed with NaOCl 5.25%. The specimens were divided into 2 groups (n = 20) according to their root canal anatomy: round, or ribbon shapes. Samples were sectioned horizontally and microscopically evaluated for canal space occupied with gutta percha /sealer relative to total canal volume. Results. To be determined. Conclusion. To be determined. Grants. This study was partially funded by the Health Professions Division grant.
