Efficacy of Laser Therapy versus Conventional Periodontal Treatment in Diabetic Patients with Periodontitis: A Systematic Review and Meta-analysis of Randomized Controlled Trials

Laser adjuncts, particularly Er:YAG and LLLT/diode, enhance periodontal treatment for type 2 diabetes mellitus (T2DM) patients, improving clinical outcomes and inflammation. Nd:YAG lasers aid healing and inflammation regulation, but benefits are often limited, and long-term effects are unclear. Comprehensive, large-scale trials are needed to shape clinical guidelines. Clinicians should consider laser adjuncts for complex cases, balancing benefits with costs and patient needs.
