Efectividad del láser de baja intensidad y PRF en la evolución postoperatoria de terceros molares

Abstract

Objective: To evaluate and compare the effectiveness of Platelet-Rich Fibrin (PRF) and Low-Level Laser Therapy (LLLT) in reducing postoperative pain, inflammation, trismus, and enhancing healing after lower third molar extraction, based on evidence published since 2010. Materials and Methods: A comprehensive literature review was conducted using PubMed, Google Scholar, and SciELO, including studies published between 2010 and 2024. After applying inclusion and exclusion criteria, 30 relevant articles were selected for detailed analysis. Results: Both LLLT and PRF were found to significantly reduce postoperative pain, edema, and trismus following third molar surgery. LLLT exerts its effects through photobiomodulation, while PRF promotes tissue repair via the sustained release of growth factors. Although the results are promising, methodological heterogeneity among studies limits direct comparisons. Moreover, current evidence regarding the combined use of LLLT and PRF remains insufficient to draw definitive conclusions. Conclusions: LLLT and PRF are effective strategies for enhancing postoperative recovery after third molar extraction. Their combined use may offer synergistic benefits; however, further research with standardized protocols is necessary to support their routine clinical application.
