Abstract :
Objectives: To evaluate the amount of calcium hydroxide remaining on canal walls after removal using manual or rotary instruments as well as the amount of apical debris during calcium hydroxide removal. Materials and Methods: Twenty-four extracted maxillary incisors were prepared with Kfiles and filled with calcium hydroxide. Four teeth served as positive and negative controls. The remaining teeth were divided into two groups: master apical file group and Protaper Universal rotary instrument group. During removal procedures, citric acid was used as an irrigant. Apically extruded debris was collected and statistically compared between the groups. Then the teeth were longitudinally sectioned, photographed using stereomicroscope, and the images were analyzed using software. Data were statistically analyzed using one-way Anova. Results: In both groups, a measurable amount of apically extruded debris was observed during calcium hydroxide removal. The statistical analysis showed that there were no significant differences between techniques in terms of the amount of apically extruded debris as well as in terms of the removal of the calcium hydroxide. Conclusions: No matter the technique, apically extruded debris during calcium hydroxide removal occurs. None of this study’s techniques completely removed calcium hydroxide from the root canal walls.
