Abstract

Introduction: The purpose of this study was to evaluate the sealing ability of three different root canal sealers with and without amoxicillin, using a push-out bond strength test.

Material and methods: Sixty single-rooted extracted human teeth were used for this study. Each tooth was instrumented and irrigated with 5.25% Sodium hypochlorite (NaOCl) and 17% EDTA. The teeth were then divided into six test groups: Gutta percha (GP)/AH Plus (Dentsply, Germany), GP/AH Plus with 10% amoxicillin (TEVA Pharmaceuticals Sellersville, PA), GP/Pulp Canal Sealer EWT (Extended Working Time, SybronEndo Orange, CA), GP/Pulp Canal Sealer EWT with amoxicillin, GP/Apexit Plus, GP/Apexit Plus (Vivadent, Tulsa, US) with amoxicillin. After the sealer was set, the entire root was sectioned into 1 mm thick slices. A push-out bond strength test was performed by using a universal testing machine. The Student's t-test was used to compare the sealer bond strength within the specific sealer test groups and within each sealer at apical, middle and coronal root levels.

Results: There was no significant difference between the groups within each sealer (p>0.05) with or without amoxicillin at the same root level.

Conclusion: This study demonstrated that the addition of 10% by weight of amoxicillin does not significantly (p> 0.05) change the overall push-out bond strength of three endodontic sealers when compared at the apical, middle, and coronal tooth level.

Keywords: AH Plus; Amoxicillin; Apexit plus; Enterococcus faecalis; Pulp canal sealer EWT; Push out bond strength.
