About Us

Dentin varnishes alleviate post-operative discomfort and prevent pulp irritation caused by certain components of cements and restoratives. They also provide an additional measure of protection against secondary decay. The most cost effective among them, Copal Cavity Varnish, is limited in its use to sealing dentin tubulae under amalgam restorations, as it interferes with the curing process of resin-based materials. Sci-Pharm's more sophisticated Universal Cavity Varnish and its counterpart, Microjoin® dentin sealer, can be used under any type of restorative or cement.
