Application purposes of HeNe L.A.S.E.R. and ultraviolet B in vitiligo

INTRODUCTION: The Vitiligo is a chronic depigmentation illness of the skin caused by loss of functional melanocytes in the epidermis. This study's objective was to compare the effects of applying L.A.S.E.R. HeNe and ultraviolet B in patients with vitiligo. METHOD: 22 patients (11 women and 11 men) aged 12-60 years (31,68 ± 16,29) were selected. Patients were randomly assigned, according to the order of attendance at the service and were divided randomly into two groups: group A (n = 12) subjected to the application of L.A.S.E.R. HeNe, where the technique used was punctual with about 3 cm distance between each point, perpendicular to the skin, and group B (n = 10) exposed to Ultraviolet B applied perpendicular 10 cm away from the patient's skin. For measurement of the treated area it was used the AUTOCAD program, which was bounded to the edge of the stain on photos taken at the beginning and at the end of treatment. RESULTS: Initially, in group A the area was 4,87 cm² ± 3,70, and after application it was 4,15 cm² ± 2,89, with an average difference of 0,72 cm² ± 1,89. In group B it was noted that before applying the average was 5,36 cm² ± 6,36, and after application it was 4,43 cm² ± 5,17, with average difference of 0,92 cm² ± 1,29. CONCLUSION: Both devices achieved significant results in reducing the stain, with a greater reduction in the group of ultraviolet.
