What this trial studies

This clinical trial evaluates the effectiveness of Lactobacillus reuteri probiotics in improving wound healing following impacted tooth extractions. It is a randomized, double-blind, placebo-controlled study that aims to assess both the primary outcome of post-extractive healing and the secondary outcome of reducing gastrointestinal symptoms associated with antibiotic therapy. Participants will receive either the probiotic or a placebo alongside standard care, allowing for a comparison of outcomes. The study seeks to provide insights into the role of probiotics in dental recovery and antibiotic side effects.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old who require impacted tooth extractions and can provide informed consent.

Not a fit: Patients with allergies to penicillin, contraindications to oral surgery, or those who are immunocompromised may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved healing and reduced gastrointestinal complications for patients undergoing tooth extractions.

How similar studies have performed: Previous studies have shown promising results for the use of Lactobacillus reuteri in dental healing, suggesting potential for success in this trial.
