Aim: To evaluate the effects of calcium hydroxide (CH), triple and double antibiotic pastes (DAPs) on the bond strength of Smart-Seal obturation, C-points with Endosequence Bio-ceramic (BC) sealer to the root canal dentin.
Materials and Methods: Sixty-four freshly extracted single-rooted human mandibular premolars were de-coronated and prepared using rotary Pro-taper system with full sequence till F3. The specimens were randomly divided into a control group (without intracanal dressing) and 3 experimental groups that received an intracanal dressing with either CH, DAP, or triple antibiotic paste (TAP) (n = 16). The intracanal dressing was removed after 3 weeks by rinsing with 10 mL 17% ethylenediaminetetraacetic acid, followed by 10 mL 3% sodium hypochlorite. The root canals were then obturated with C-points and Endosequence BC sealer. A push-out test was used to measure the bond strength between the root canal dentin and the obturating system. The data were analyzed using two-way analysis of variance and Tukey post-hoc test.
Results: The push-out bond strength values were significantly affected by the intracanal medicaments (P < 0.001), but not by the root canal thirds (P > 0.05). In the middle and apical third, the bond strength of the TAP group was higher than those of the CH and DAP groups (P < 0.05).
Conclusions: The DAP and CH did not affect the bond strength of the novel hydrophilic obutrating system. TAP improved the bond strength of Smart-Seal system in the middle and apical thirds. |
