Is this trial a fit for you?

Likely a good fit

Ideal candidates include patients with permanent molars diagnosed with apical periodontitis and a Periapical Index (PAI) score of 2 or higher.

Probably not a fit

Patients with immature roots, non-restorable teeth, or those with allergies to diclofenac sodium may not benefit from this study.

What this trial studies

This clinical trial aims to assess the effectiveness of diclofenac sodium as an intracanal medicament compared to calcium hydroxide in treating chronic apical periodontitis in permanent molar teeth. Participants will be randomly assigned to receive either diclofenac sodium or calcium hydroxide, and the study will measure bacterial reduction through microbiological assessments before and after treatment. The goal is to determine if diclofenac sodium can serve as a viable alternative to traditional treatments in endodontics.

Why it matters

Potential benefit: If successful, this study could provide a new, effective treatment option for patients suffering from chronic apical periodontitis.

How similar studies have gone: While the use of diclofenac sodium in this context is relatively novel, similar studies have explored the antimicrobial properties of various intracanal medications, indicating potential for success.
