The aim of this study was to evaluate the effect of a commercially available irrigant,the Qmix 2 in 1, on the push out bond strength of Endosequence BC which is abioceramic based root canal sealer.Material and methodsSixty extracted maxillary central incisors were prepared with Protaper Next rotaryinstrument up to X4 (# 40). The specimens were randomly divided into four groups ofequal sample size (n=15), according to the final irrigation regimen as follows: Group 1:2.5% sodium hypochloride (NaOCl) (control), Group 2: 17% ethylenediaminetetraaceticacid (EDTA), Group 3: 2% Chlorhexidine (CHX), Group 4: QMix 2 in 1. After rinsing,teeth were obturated using gutta-percha with Endosequence BC sealer. Slices wereobtained from coronal, middle, and an apical section of the root canal. Push-out testwas performed to evaluate the bond strength between the root canal dentin and thesealer. Data was statistically analyzed.ResultsThe push-out bond strength of the root canal sealer was significantly affected by thetype of irrigation solution. Highest bond strengths were found in canals irrigated withQmix solution, and these results were regardless of anatomical section of the rootcanal (p< 0.05).ConclusionFinal irrigation of the root canals with QMix had a positive effect on the bond strengthof Endosequence BC sealer throughout the root canal.
