Comparing two methods of activating a bio-ceramic sealer for pain relief in root canal treatments

The Effect of Eddy Sonic Versus AF Max Activation of Bio-ceramic Sealer on Post-operative Pain in Teeth with Symptomatic Irreversible Pulpitis with Apical Periodontitis

Not applicable Interventional Future University in Egypt · NCT06640218

What this trial studies

This clinical trial evaluates the effectiveness of two different activation methods, Eddy Sonic and AF Max, for a bio-ceramic sealer in reducing postoperative pain in patients undergoing root canal treatment for irreversible pulpitis with apical periodontitis. A total of 30 patients will be recruited and divided into three groups, with one group receiving no activation as a control. The study aims to determine which method provides better pain relief after the procedure. Participants will be selected based on specific inclusion criteria, ensuring they have the appropriate dental condition and are systematically healthy.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 40 with symptomatic irreversible pulpitis in mandibular first molars who are seeking root canal treatment.

Not a fit: Patients with ASA classifications other than ASA I and II or those who have taken preoperative analgesics within 12 hours may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management strategies for patients undergoing root canal treatments.

How similar studies have performed: While there is limited information on the specific methods being tested, similar studies in endodontics have shown varying degrees of success in pain management techniques.

Eligibility criteria

Inclusion Criteria:

* Age range is from 18 to 40 years old.
* No sex predilection
* Patients seeking root canal treatment.
* restorable teeth.
* Positive patient acceptance for participating in the study.
* patients able to sign informed consent.
* Systematically healthy patient (ASA I, Il).
* Patient who can understand the numerical rate scale and sign an informed consent.
* Mandibular first molar teeth with pain on bite or percussion
* Preoperative sharp (moderate or severe) pain.

* widening in periodontal membrane space in radiographic appearance.

Exclusion Criteria:

* Patients with American Association of Anesthesiologists (ASA) classifications other than ASA 1 \& Il
* Patients who have already ingested preoperative medication, such as analgesics, non-steroidal, or steroidal anti-inflammatory drugs, within 12 hours of the start of treatment.
* This was done to prevent any misinterpretation of the diagnosis or post-treatment pain severity, as these drugs substantially lower post-endodontic pain (Jorge-Arajo et al.,2018).
