Abstract

An in vitro study using radioactively-labeled tissue culture cells was conducted over a seven-month period on Grossman's sealer, Rickert's sealer, N2 Permanent, and Cavit to determine the lasting and relative tissue toxicity of these materials.

From this study it was observed that all materials possess lasting tissue toxicity. When relative toxicity is considered, Grossman's is the most toxic, followed by N2, Rickert's and Cavit in descending order of toxicity. Both Grossman's and N2 would be considered highly toxic, with Rickert's displaying moderate toxicity. Cavit would be considered mild to moderate in toxicity.

The use of radioactively-labeled tissue cells as a method of testing root canal filling materials is a rapid, highly sensitive method which allows adequate cell-material contact and permits objective quantitation of cell damage with accuracy.
