An interventional study of Obturation of root canals in Dental Pulp Necrosis, sponsored by Jordan University of Science and Technology. Completed at 1 site in Jordan. Open to participants aged 18 Years to 60 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-02-04.

Postoperative pain is an important consideration in endodontic treatment, and its incidence may be influenced by both obturation technique and sealer type. This study focused on molars to minimize anatomical variability and provide a consistent assessment of pain associated with different endodontic protocols.
This study aimed to evaluate the incidence and level of postoperative pain in molars treated with root canal therapy, in relation to the type of sealer and obturation technique used.
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.

Pain level after obturation of root canals
The level of pain the patient will experience after obturation of the teeth using a visual analogue scale and a numerical scale from 0-10. Zero is the minimum and 10 is the maximum. The higher the score the worse it is, the best technique will have low scores of pain
Time frame: 6 hours, 1 day, 2 days, 3 days and 1 week
