What this trial studies

This clinical trial aims to evaluate the effectiveness of two different instrumentation techniques, the reciprocating system Reciproc Blue and the rotating system VDW.ROTATE, in performing pulpectomies on primary molars in children aged 4 to 8 years. Conducted at the International University of Catalonia, the study involves a randomized controlled design with 60 participants divided into three groups, each receiving a different treatment approach. The students in the master's program in Pediatric Dentistry will perform the procedures under supervision, ensuring standardized training and calibration. Data will be collected and analyzed to determine the success rates of each technique.

Who should consider this trial

Good fit: Ideal candidates are children aged 4 to 8 years with vital or non-vital temporary lower second molars that meet specific radiographic criteria.

Not a fit: Patients with systemic diseases, special needs, or those who are very uncooperative may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve treatment outcomes for children with pulp disease in their primary molars.

How similar studies have performed: Previous studies have shown varying success with different instrumentation techniques in pediatric dentistry, making this approach both relevant and necessary.
