PURPOSE: To evaluate the microtensile bond strength (µTBS) of adhesive resins after cleaning the calcium silicate-based root canal sealer (CSBS) removed from the dentin with different solvents and cleaners.
METHODS: 70 human molar teeth were randomly divided into seven main groups. All surfaces were rinsed with 2% NaOCl and 17% EDTA and contaminated with CSBS. Solvents or cleaners used were as follows: no sealer, no solvent, chloroform, ethanol, Endosolv E, phosphoric acid, and hydrofluoric acid. All groups were divided into Subgroup U (universal adhesive) and Subgroup S (two-step self-etching adhesive). Composite build-ups were made with a nanocomposite. Dentin-composite sticks were obtained from each tooth (n=11). µTBS testing was performed, and stereomicroscopic and scanning electron microscopic (SEM) analyses were performed.
RESULTS: The µTBS values of Endosolv E were statistically the highest among the groups (P< 0.05). When comparing the adhesive systems, the µTBS values of the self-etching adhesive groups were significantly higher in no sealer and ethanol groups. Endosolv E produced a better adhesive-dentin bond than the other groups. The self-etching adhesive showed a better bond regardless of the solvent used. Endosolv E and self-etch adhesive may be suitable for adhesive procedures after endodontic treatment with CSBS.
CLINICAL SIGNIFICANCE: Endosolv E, in conjunction with a self-etching adhesive, may prove an efficacious method for cleaning residual sealer and adhesive procedures following endodontic treatment with CSBC.
