摘要：

The toxic effects of modified endodontic sealers, Fillcanal, N-Rickert, FS, and Sealer 26, were assessed. The material toxicity was measured through radiochromium release method that uses direct and indirect contact methods. The sealers were evaluated freshly mixed and after various setting times. L929 mouse and periodontal ligament fibroblast cells were used as target cells. Fillcanal, N-Rickert, and FS showed high toxicity. Fillcanal leaches toxic material when fresh and after setting time. Sealer 26 was the least toxic.
