In the conventional hand-file group, the trend of pain reduction was gradual and continuous.Ĭomparison of the mean pain score after treatment among the study groups at different time points revealed no significant difference among the three groups in the severity of pain at 6, 48 and 72 hours post-treatment but the mean pain score at 12 and 24 hours was significantly higher in the Safe Sider group compared to the conventional hand-file and Mtwo groups (P=0.001 and P=0.001, respectively (Fig. Post-endodontic pain significantly decreased over time in all groups. The data were analyzed using repeated measures ANOVA. The severity of postoperative pain was assessed using a Visual Analog Scale (VAS) at 6, 12, 24, 48 and 72 hours. Their root canals were randomly instrumented with hand files, Mtwo and Safe Sider instruments. Methods: A total of 150 maxillary and mandibular molars with symptomatic irreversible pulpitis were selected. Objectives: This study compared post-endodontic pain following the use of Mtwo and Safe Sider multiple file system.
