82 - Evaluation of Different Coronal Sealing Materials on Endodontically Treated Teeth

Abstract

In vitro studies have shown that rapid penetration of bacteria in the entire root canal system may occur after endodontic treatment without an efficient coronal seal. A proper restorative technique is necessary to ensure this, but there are a lot of materials out there. The aim of this study is to determine which type of restorative materials offer the best possible outcome. The evaluation of the coronal sealing ability of the most relevant clinical materials was done by means of dye penetration (neutral red dye, Sigma-Aldrich, Germany), through the restorative material-tooth interface. Tests were done on all sampled using a light spectrometric device, to establish which one of the tested dental materials possesses the best sealing ability, as in the least microleakage. Forty-two extracted teeth were prepared and used for this experiment; they were sealed with 5 different restorative materials. The flow composite had the best absorbance value with 0.00675 ± 0.00096 (mean ± standard deviation) for monoradicular samples and 0.025 ± 0.00129 for pluriradicular samples. The best material for coronal reconstruction post-endodontic treatment is the flow composite, which had the best sealing ability, followed by the packable composite.
