Abstract
Objective: The aim of this study was to compare the smear layer removal efficacies of 5.25% sodium hypochlorite (NaOCl) and QMix TM (Dentsply Tulsa Dental Specialties, Tulsa, OK, USA) in the coronal, middle, and apical thirds of the root canal using a common irrigation protocol in deciduous teeth. Materials and Methods: Forty extracted human single-rooted deciduous teeth were prepared to 40 K file. Prepared teeth were randomly divided into two groups (n = 8); 5.25% NaOCl (group 1) and QMix TM (group 2). Following final irrigation with tested irrigants, the decoronated teeth were split into two halves longitudinally and evaluated and assessed for the amount smear layer present under a scanning electron microscope (SEM). The SEM images were analyzed for the amount of smear layer present using a score system criteria by Rome et al. Data were analyzed using the Fischer exact test. Results: Intergroup comparison of groups 1 and 2 showed statistically significant differences in the coronal (P = 0.001) and middle thirds (P = 0.032); however, in the apical third the canal surfaces were cleaner in samples from group 2 (P = 0.046) as compared to group 1. Conclusion: QMix TM is effective as a final irrigation agent for the removal of smear layer in the coronal, middle, and apical thirds of the root canals in deciduous teeth.
