Abstract
BACKGROUND/ METHODS: Transmission of 362 nm ultraviolet A radiation (UVA) through epithelium of oral mucosa and skin epidermis was compared in rat and man. The transmitted irradiance was measured by means of a radiometer. RESULTS: In man, significantly (P<0.01) greater transmittance (2.8-fold) was observed in skin compared to buccal mucosa. In rat, no significant differences were found. CONCLUSION: In different species and different types of epitheliae, separate studies are needed for the evaluation of UVA transmission.
