[6 dentin adhesive products subjected to controls in vitro]

The aim of this in vitro study was to assess of the biocompatibility of 6 adhesive dental products (Cavalite, Dual Cement, Fuji Type II, Gluma, Ketac Bond, Scotch Bond) using cell cultures of human pulps and a standardized method. It was thus possible to improve the scale of biological activity proposed by Regad et al., (1989). The specific behaviour of the cells in the contact and adjacent zones has been added to the assessment of the cellular reactions of the whole culture. These criteria allowed the clear differentiation of the toxicity and the biocompatibility of the products. The following estimations were made: Gluma and Fuji Type II "toxic", Cavalite "acceptable", Scotch Bond "not significant", Ketac bond and Dual Cement "acceptable" and "not significant" with a "toxic" tendency.
