[Long-term animal experimental studies of a new dentin and pulp protective varnish (Bayer D-520)]. 1978

H Triadan

A new polyurethan varnish (Bayer D-520) was tested on 4 monkeys with a total of 96 cavities after the norms of "Recommended standard practices for biological evaluation of dental materials" of the ADA 1975. After the successful short-term experiment of two weeks, a long-term examination of dentin and pulp protective properties followed. 6 combinations were used: - 16 silicate cement fillings with varnish, 16 with Dycal base (negative control), 16 without protection (positive control) - 16 composite fillings with varnish, 16 with Dycal and 16 without protection After an observation time of 3 months, with marks of 0-3 for each criterion of the histological sample a significant difference (p less than or equal to 0.01) in favour of the varnish- and Dycal-protected cavities resulted. A difference between the varnish and the Dycal base could not be statistically established.

D011140	Polyurethanes	A group of thermoplastic or thermosetting polymers containing polyisocyanate. They are used as ELASTOMERS, as coatings, as fibers and as foams.	Polyisocyanates,Ostamer,Pellethane,Spandex,Ostamers,Pellethanes,Polyisocyanate,Polyurethane,Spandices
D003736	Dental Cavity Lining	An inner coating, as of varnish or other protective substance, to cover the dental cavity wall. It is usually a resinous film-forming agent dissolved in a volatile solvent, or a suspension of calcium hydroxide in a solution of a synthetic resin. The lining seals the dentinal tubules and protects the pulp before a restoration is inserted.
