Bioceramic vs Calcium Hydroxide in Root Canal Medicaments for Symptomatic Apical Periodontitis

Official title: Clinical Evaluation of the Postoperative Pain and Substance P Levels Following the Use of Bioceramic Verses Calcium Hydroxide Intracanal Medicaments in Permanent Mandibular Molars With Symptomatic Apical Periodontitis

Run by Future University in Egypt · NCT07585721 · Data updated 2026-11-12

Is this trial a fit for you?

Likely a good fit

Adults aged 18-45 with permanent mandibular molars diagnosed with symptomatic apical periodontitis and no systemic conditions that could affect pain response.

Probably not a fit

Patients with conditions or factors that predispose to low baseline pain or non-responsive inflammatory processes may not experience a differential benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Adults with symptomatic apical periodontitis in permanent mandibular molars are randomized to receive either calcium hydroxide or a bioceramic intracanal medicament after standardized endodontic treatment. Postoperative pain will be recorded using a visual analog scale at multiple time points, and Substance P levels will be measured as a biomarker of pain and inflammation. The study aims to compare pain outcomes and biochemical markers between the two materials to inform clinical decision-making in endodontic therapy. A total of 28 participants are planned, with 14 in each group, under the supervision of Future University in Egypt.

Why it matters

Potential benefit: If successful, patients may experience lower postoperative pain and reduced inflammatory response with bioceramic medicaments.

How similar studies have gone: Previous endodontic studies have explored intracanal medicaments with mixed outcomes; this study adds novel measurement of Substance P alongside clinical pain.
