Abstract
Aim: To compare the shear bond strengths of a calcium silicate-based root canal sealer (CSS), to dentin or calcium silicate-impregnated gutta-percha (CSGP), with the shear bond strengths of an epoxy resin-based sealer. Methods: For sealer/dentin testing, 40 hemisectioned roots were divided into 2 groups. Coronal root dentin discs were bonded with CSS or epoxy resin-based sealer. For sealer/core material testing, CSGP and conventional gutta-percha discs were bonded with a matching sealer (N = 20 per group). The shear bond strengths were tested using a universal testing machine. The failed modes were analyzed using stereomicroscopy and scanning electron microscopy. Results: The CSS sealer had significantly higher shear bond strength to dentin than did epoxy resin-based sealer (P <.01). However, shear bond strengths of the 2 sealers to core materials did not significantly differ (P =.74). The remnants of the CSS sealer adhering to dentin or calcium silicate gutta-percha disc were observed. Conclusions: The CSS sealer had better adhesion to dentin than did epoxy resin-based sealer. However, the bond of the CSS sealer to impregnated gutta-percha was not superior to the epoxy resin-based sealer bonded to conventional gutta-percha.
