and physiologic saline eluates of a dentin adhesive. Two other products exhibited no mutagenicity.Itwasconcludedthatthemutageniceffectsofoneof those dentin adhesives (SyntacFmv) were induced by thegenotoxic ingredient, glutaraldehyde (Schweikl et al., 1994). Dose-dependent mutagenicity was found in Ames tests with unpolymerized rnaterial oftwo dentin adhesives. Genotoxic effects were also caused bymonomeric solutions used in orthodontics for cemen- tation. However, no specific component was identified as the causative agent in those studies (Athas et al.,1979;Lietal.,1990).
