[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.

Elution of cadmium from dentures.

Heat-cured, pink-pigmented (light veined) Stellon maxillary acrylic denture blanks were shaken in 150 ml synthetic saliva varied from 0.15 to 1.05 mug independently of elution time. With o.1N CH3COOH the amount of cadmium, varying from 1,20 to 2.55 mug, increased slowly with elution time. Another batch of Stellon gave higher values in 0.1N CH3COOH.
