LOW-LEVEL POTENCY LASER AS TREATMENT AT RECURRENT APHTHOUS STOMATITIS ON HIV PATIENTS

Abstract

Recurrent aphthous stomatitis (RAS) is a usual pathologic alteration found in the oral mucosa, defined by unique or multiple painful ulcers. Its etiopathology is not very well known. However, it is known that the low count of CD4 T lymphocytes increases the prevalence of oral lesions. In other words, immunosuppressed patients with human immunodeficiency virus (HIV) are predisposed. A 26-year-old dark-skinned male patient, HIV-positive, CD4 T cell 67, showed minor RAS in the upper lip area and lower lip on the right side, measuring approximately 5 mm, and larger RAS on the tongue and tonsillar pillar measuring 2.5 cm. The chosen treatment was dexamethasone elixir mouthwash and, as supporting therapy, the application of a low potency laser at 790 nm, punctually, for 2 minutes. Remission of injuries was noted. A GaAIAs laser is an important therapeutic approach for ulcer treatment.
