Abstract

While a gutta-percha system is most commonly used by practitioners for canal obturation, there is no agreement on how best to close the chamber of an endodontically treated tooth. Some materials used in restorative dentistry may have endodontic applications. Restorative materials of particular interest to endodontists are those used as subgingival restorations. Their properties include insolubility in oral fluids, adhesiveness, dual-cure capabilities, radiopacity, hardness and fluoride release, low cure shrinkage and a low coefficient of thermal expansion. The purpose of this in vitro study was to test three products that could be used to seal pulp chambers of endodontically treated teeth to prevent bacterial infiltration. A bacteriological assay system was used to determine the efficacy of three commercially available restorative materials to prevent penetration of Streptococcus salivarius from the pulp chambers into the prepared canals. The materials evaluated were: Geristore® two-paste system with Tenure Quik with fluoride, Dispersalloy® with Tenure Quik with fluoride, and Marathon® posterior composite with Tenure Quik with fluoride. During the sixty days of the study, the analysis indicated that the Geristore two-paste system with Tenure Quik with fluoride provided a statistically significant improved seal when compared to the Marathon posterior composite and Dispersalloy amalgam with Tenure Quik with fluoride.
