["In vitro" evaluation of the action of various cavity varnishes].

Abstract

The authors studied in vitro the capacity of FORP-USP cavity varnishes, COPALAINE (Prodonto), COPALITE (H. J. Bosworth Co.), CAVITINE (SS WHITE) and UNIVERSAL (SS WHITE) to promote impermeabilization. The tests were done by the use of filter paper and the impermeabilization was measured by the Rhodamine B stain infiltration. The FORP-USP cavity varnishes Copalaine and Copalite were more effective in promoting impermeabilization.
