Recurrent aphthous stomatitis (RAS) is a chronic, ulcerative condition of the oral mucosa that affects 10–25% of the population. The etiopathogenesis of the disease is not fully understood, although a polygenic mode of inheritance and immunological dysregulation have been suggested in several studies. The contribution of numerous predisposing factors, such as a deficiency of iron, vitamin B12 or folic acid, trauma, emotional stress, endocrine disturbances, or allergy, have also been considered. So far, no causative treatment for RAS has been developed; instead, topical and systemic drugs are used to reduce pain and inflammation, and to lengthen the period of remission. Low-level laser therapy (LLLT) is a non-invasive and atraumatic therapeutic method that involves the local application of a high-density, monochromatic, narrow-band light source. With the use of the appropriate power and wavelength, the therapy brings anti-inflammatory and analgesic results, and wound healing is promoted. Several reports on the beneficial effects of LLLT in RAS have been presented recently. This report describes 2 cases of adult patients with RAS treated with LLLT to relieve pain and promote the healing of the ulcers. The clinical presentations with the signs and symptoms are discussed and illustrated, along with the treatment algorithms and outcomes.
