The Effect of Sealer Type and Obturation Technique on Postoperative Pain

One hundred and twenty patients (aged 18-60 years; 63 males, 57 females) requiring root canal treatment of mandibular or maxillary molars will be included. Only teeth with necrotic pulp and asymptomatic apical periodontitis or previously extirpated pulp are considered. Patients will be randomly assigned to one of four groups (30 patients each): Group A-AH Plus resin sealer with cold lateral compaction (AH-CLC); Group B-AH Plus with warm vertical compaction (AH-WVC); Group C-TotalFill bioceramic sealer with single-cone technique (TF-SC); Group D-TotalFill HiFlow with warm vertical compaction (TF-WVC). Postoperative pain will be self-recorded using the Visual Analog Scale (VAS) and Verbal Rating Scale (VRS) at 6 hours, 1 day, 2 days, 3 days, and 1 week after treatment. Completed forms will be collected when patients returned for permanent coronal restoration. Analgesic use was also recorded. Data will analyzed using one way ANOVA and Chi square tests.
