This article compares the effectiveness of using narrow-band UVB in contrast to broadband UVB. Results were evaluated by means of Psoriasis Severity Index scores, as well as quantitative histologic measure. After the study was conducted, it was found that 81.8% of patients receiving narrow-band UVB exposure obtained clinical clearing of their psoriasis, while only 9.1% of patients noticed clearing after broadband UVB treatments. “[Narrow-band] UVB is superior to [broadband UVB] in reversing psoriasis at suberythemogenic doses.”
