Low power laser radiation treatment in patients with recurrent aphthous stomatitis

Background: among the periodontal emergencies that require immediate attention is the RAS, due to the inconvenience or complications that it causes to the patient. The use of low power laser radiation can be effective in the treatment of this entity.Objective: to determine the therapeutic effect of treatment with low-power laser radiation in patients diagnosed with recurrent aphthous stomatitis.Methods: descriptive, cross-sectional study, carried out from May/2019 to May/2021, in the Dr. Enrique Barnet polyclinic’s dental service, in Lajas municipality, Cienfuegos province, which included 46 patients diagnosed with recurrent aphthous stomatitis. Document analysis, observation and questionnaire were used; in addition to the oral examination as a diagnostic method. Patients received treatment with low-power laser radiation. The EPIDAT 3.1 program was applied for the statistical data processing.Results: the female sex predominated, the age between 19-34 years, as well as minor aphthous ulcers. The lesions were located mainly on the lip. 97.83% of the patients reported remission of the lesion on the fifth day of treatment. All treated patients evolved favorably towards healing. Only one patient presented adverse reactions.Conclusions: the results allowed us to verify the therapeutic benefits of low power laser therapy in the treatment of recurrent aphthous stomatitis.
