Adel Bouguezzi*, Maroua Garma

Trigeminal neuralgia is a pain passes through nerve's branches and its trigger is located in skin or mucosa that could lead to pain with a trigger stimulus. The pain involved branches of trigeminal nerve that sometimes has patients to seek the treatment for several years. Low-Level Laser Therapy (LLLT) is a treatment strategy which uses a single wavelength light source. In this article, we report on four patients who were diagnosed with Persistent Idiopathic Facial Pain (PIFP). All patients were treated with LLLT system that produces low-energy infrared light (808 nm diodes). The laser was applied to the symptomatic locations. Patients were treated once per day for five consecutive days, followed by a two-day interval. This regimen continued until the total number of applications reached 20. The results of our study show that LLLT could have beneficial effect on patients with orofacial pain as partial or total resolution of symptoms.
