A Systematic Review of Laser Pulpotomy in Pediatric Dentistry: Clinical Efficacy and Outcomes Compared to Conventional Techniques

Abstract

Laser pulpotomy has emerged as a promising alternative to conventional pulpotomy techniques in pediatric dentistry. This systematic review critically evaluates recent studies investigating the efficacy of laser modalities—particularly diode, Er, Cr: YSGG, and photobiomodulation lasers—when used in the pulpotomy of primary teeth. Comparative analyses with traditional materials such as formocresol and mineral trioxide aggregate (MTA) were conducted to assess clinical and radiographic success rates. The findings indicate that laser pulpotomy yields comparable or superior outcomes, with reported advantages including enhanced hemostasis, reduced intraoperative bleeding, shortened treatment time, and improved patient comfort. Additionally, this review highlights differences in laser-tissue interaction, mechanisms of action, and procedural protocols among various laser types. Despite encouraging evidence, heterogeneity in methodology and follow-up periods across studies underscores the need for standardized clinical protocols and long-term randomized controlled trials. Overall, laser pulpotomy represents a clinically effective and patient-friendly option that warrants further investigation for widespread implementation in pediatric dental practice.
