Abstract

This study aimed to evaluate the quantity of apically extruded debris during the bio-mechanical preparation of the root canal treatment. Fifteen extracted premolars with single root canal were collected and divided into three groups for this study. Hand protaper files (reaming motion), K files (watch-wind motion), and K flex files (balanced force technique) were used. The irrigant and debris were collected in pre-weighed (using analytic scale) empty microtainer bottles. The microtainers were kept in an incubator at 70⁰C for 4 days for complete drying and then weighed of dry debris was recorded. Statistical analysis: Data was treated for the mean values of the weight and analysed using kruskall-wallis test at a significance of 0.05. All the three motions of hand files extruded debris. Watch wind motion showed the lowest mean value whereas reaming showed the highest. There were no significant difference between the reaming motion, watch wind motion and balanced force technique (p <0.05). The study revealed that the amount of extruded debris from the apical foramen was comparatively least in watch wind motion among all the three motions in terms of the mean weight but there is no significance difference between the three Groups.
