The Effect of Sealer Type and Obturation Technique on Postoperative Pain

The Effect of Sealer Type and Obturation Technique on Postoperative Pain of Root Canal Treated Teeth

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.

Inclusion Criteria:

1. both male and female patients within
2. The age of 18-60 years old who required root canal treatment
3. Either mandibular or maxillary molars with the diagnosis of either; necrotic pulp with asymptomatic apical periodontitis,
4. Teeth with pulp extirpated ( previously initiated root canal treatment) regardless of the periapical status

Exclusion Criteria:

1. Teeth diagnosed with irreversible pulpitis;
2. Teeth with intracanal abberations or mishaps such as perforations, transportation, severe ledging , broken instruments, apical resorption or open apices;
3. Teeth requiring posts;
4. Any patient on long term steroid or any other medical condition that requires long term analgesic.
