What this trial studies

This study aims to evaluate the clinical effectiveness of a single rotary file system compared to a multiple rotary file system in performing pulpectomy on primary molars affected by irreversible pulpitis. The research focuses on pediatric dentistry, addressing the challenges of traditional hand file techniques that can be time-consuming and stressful for children. By utilizing rotary endodontics, the study seeks to determine if a single file system can provide a more efficient and effective treatment option. The trial will assess both clinical and radiographic outcomes to establish the best approach for managing necrotic primary teeth.

Who should consider this trial

Good fit: Ideal candidates for this study are medically healthy children with cooperative behavior who have mandibular second primary molars showing signs of irreversible pulpitis.

Not a fit: Patients who are uncooperative, have systemic diseases, or whose parents do not provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more efficient and less stressful dental treatments for children with pulpitis.

How similar studies have performed: This approach is novel, as no previous clinical trials have compared the effectiveness of single versus multiple rotary file systems in pulpectomy for primary molars.
