[Denture cleaning with an enzyme-containing laundry detergent].
An enzyme containing laundry detergent (Rex) was tested as a denture cleanser. It was found more satisfactory than the denture cleansers available on the Norwegian market.
[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.
