Introduction/Objectives the aim of this study is to compare the difference in the postoperative pain when resin cements are used in comparison to bio ceramic cements in the obturation of root canals.
Methods One hundred patients with permanent molar teeth requiring endodontic non-surgical retreatment were treated in this study. Preoperative assessment of the degree of the patient's pain was done using the visual analog scale. Fifty teeth were obturated with gutta percha using the epoxy resin-based sealer as the control group, and in the other fifty bio ceramic based cement was used. All teeth were prepared by the protaper next rotary files under copious irrigation with 30ml of 2.6 % sodium hypochlorite throughout the procedure. Obturation was done using the cold lateral compaction technique in the resin group and single cone technique in the bioceramic group. Postoperative pain assessment was done for each patient after six hours, twenty-four hours, four days and one week.
Results There was no statistically significant difference between pain scores regarding the postoperative pain between single cone bioceramic based obturation retreatments in comparison to the lateral compaction epoxy resin based obturation retreatments after 6, 24, 48 hours as well as one week. It was also found that There was no statistically significant difference between them in relation to age values and gender in the two groups. Conclusion with in the limitation of this study Single cone obturation with bioceramics can be used safely in single visit retreatment cases, when postoperative pain is being considered.
