Abstract

Objectives: The aim was to investigate the effect of intracanal irrigants and agents on the bond strength of intraradicular fiber posts to dentin. Materials and Methods: Root canals of 72 decoronated single-rooted premolars were cleaned, shaped, and obturated with gutta-percha and AH26. The specimens were incubated at 37oC and 100% humidity for seven days. Next, the coronal 10 mm of the canals were prepared to receive size 2 D. T. Light fiber post, and the specimens were randomly allocated into six groups according to the irrigants used after post space preparation: normal saline (control group), 5. 25% Sodium Hypochlorite (NaOCl)/15 seconds, 17% ethylenediaminetetraacetic acid (EDTA)/60 seconds, 2% Chlorhexidine (CHX)/5 minutes, MTAD/5 minutes, and acid-etching/15 seconds. All canals were rinsed with normal saline and dried. Fiber posts were cemented using Panavia F2. 0. After 24 hours, two mid-root slices of 1mm thickness were obtained from each specimen. Push-out bond strength test was performed in a universal testing machine at 0. 5mm/minute. The maximum applied load was recorded, and the bond strength was calculated in megapascal (MPa). Data were analyzed by one-way analysis of variance (ANOVA) and Tukey's test. Results: The mean shear bond strengths of etched (53. 21± 12. 11 MPa), MTAD (52. 47± 14. 75 MPa) and EDTA (49. 08± 10. 19 MPa) groups were significantly higher than that of the control group (39. 82± 10. 04 MPa). The difference was marginally significant for CHX group (49. 8± 13. 57 MPa) and not significant for NaOCl group (47. 15± 17. 64 MPa). Conclusions: Etching or irrigating the root canals with MTAD or EDTA after post space preparation increases the bond strength of Panavia F2. 0 to dentin.
