title: [Animal experimental studies on a new dentin and pulp-protective lacquer (Bayer D-520)].
abstract: In an ADA experiment on the protective qualities of a new polyurethane varnish (D-520 Bayer) 72 class 5 cavities were prepared on 3 monkeys and treated by the following 4 methods: -- 18 silicate cement (Bio-Trey) with varnish -- 18 silicate cement (Bio-Trey) without varnish -- 18 composite (Adaptic) fillings with varnish -- 18 composite (Adaptic) fillings without varnish. After an observation time of 14 days, a significant positive result for the 520 varnish could be obtained. An experiment lasting 12 weeks was subsequently undertaken.
