Abstract

With an aim to determine minimum erythema dose of narrow band UV-B, 30 subjects, 20 with type IV skin and 10 with type V skin were subjected to graded incremental doses of 311-Narrow band UV-B phototherapy cabiner by Daavlin. Barely perceptible erythema 24 hours after exposure was taken as MED. 33.3% developed erythema at 745 mj, 26.6% at 620 mj, 23.3% at 1075 mj, and 10% at 1290 mj. The average MED for narrow band UV-B exposure for type 1V skin was 600 mj, [range 5515-755 mj] and for type V skin 1100 mj {range 895-1290 mj}. Better therapeutic response can be obtained by giving approximately 360-450 mj as initial irradiation dose for type 1 V skin and 600-825 mj for type V skin.
