ABSTRACT: Trigeminal nerve injuries, particularly to the inferior alveolar and lingual nerves, are recognized complications of dentoalveolar surgery, often leading to sensory disturbances such as paresthesia, dysesthesia, and taste alterations. This study explores the therapeutic potential of photobiomodulation (PBM) in four clinical cases involving post-surgical nerve injuries. A 980 nm diode laser was used in extra- and intra-oral applications over 8 to 15 sessions. Patients reported progressive sensory recovery, with complete resolution of symptoms in all cases. PBM therapy, a non-invasive technique, appears to enhance nerve regeneration by promoting blood flow, stimulating Schwann cell activity, and reducing fibrosis. These findings align with existing literature supporting PBM’s efficacy in peripheral nerve recovery. While conservative approaches and surgical options exist, PBM offers a safe and effective alternative. Further large-scale studies are needed to standardize parameters and validate their use in clinical practice for managing trigeminal nerve injuries.
