LACK OF CORRELATION BETWEEN THE AMOUNT OF EUGENOL RELEASED FROM ZINC OXIDE-EUGENOL SEALER AND CYTOTOXICITY OF THE SEALER

The purpose of this study was to examine a possible correlation between the eugenol released from a zinc oxide-eugenol sealer (Canals) and the degree of cytotoxicity. The cytotoxicity and eugenol release from root canal filling material containing eugenol was examined for test solutions at several experimental periods. No positive correlation was found between eugenol release and cytotoxicity of the root canal filling material.
