| Summary: | DOI: 10.26650/eor.2018.446Purpose
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 a bioceramic based root canal sealer.
Material and methods
Sixty extracted maxillary central incisors
were prepared with Protaper Next rotary instrument up to X4 (# 40). The
specimens were randomly divided into four groups of equal sample size (n=15),
according to the final irrigation regimen as follows: Group 1: 2.5% sodium
hypochloride (NaOCl) (control), Group 2: 17% ethylenediaminetetraacetic acid
(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
were obtained from coronal, middle, and an apical section of the root canal.
Push-out test was performed to evaluate the bond strength between the root
canal dentin and the sealer. Data was statistically analyzed.
Results
The push-out bond strength of the root
canal sealer was significantly affected by the type of irrigation solution.
Highest bond strengths were found in canals irrigated with Qmix solution, and
these results were regardless of anatomical section of the root canal (p<
0.05).
Conclusion
Final irrigation of the root canals with
QMix had a positive effect on the bond strength of Endosequence BC sealer
throughout the root canal. |
