[Dental status in blacklight]

Patients exposed to long-wave ultra-violet lighting (blacklight) used in nightclubs, discoteques etc., present specific esthetic demands as regards restaurative and prosthetic dental materials. The appearence of some randomly selected dental materials were compared in blacklight (Osram lamp, 365,5nm) and normal, artificial light. Of the prosthetic materials, acrylic teeth showed a fluorescens in blacklight more like natural teeth than porcelain. Several tooth coloured materials appeared far from tooth coloured in this particular lighting.
