Laser Pulpotomies' Clinical and Radiographic Success in Primary Teeth by Type of Laser

Background/Objectives: The aim of this literature review is to evaluate the clinical and radiographic success of various types of lasers used in pulpotomy procedures for primary teeth. Methods: A comprehensive literature search was conducted using PubMed and Web of Science databases, with no time limits applied. Keywords included various types of lasers (e.g., diode, Nd:YAG, Er:YAG, LLLT, CO₂) and terms related to pulpotomy in primary teeth. The search was performed in August 2025. Studies were screened for eligibility based on inclusion and exclusion criteria, focusing on clinical trials and studies assessing long-term outcomes of laser pulpotomies. Results: The review included 36 studies, categorized by laser type. Diode lasers were the most commonly used laser and showed high clinical success rates (>85%) with various dressing materials. Nd:YAG lasers demonstrated positive long-term outcomes, while Er:YAG lasers had inconsistent results. Low-Level Laser Therapy (LLLT) and CO₂ lasers also showed high clinical and radiographic success. The studies highlighted the variability in laser specifications and clinical protocols, making direct comparisons challenging. Conclusions: Laser pulpotomy offers a viable alternative to traditional methods, with diode and Nd:YAG lasers showing particularly high success rates. However, the lack of standardized protocols and the variability in study methodologies call for further research to establish clear guidelines for clinical practice.
