[Evaluation of the histocompatibility of endodontic cement in subcutaneous connective tissue using three methods].
It was employed three methods to evaluate the histocompatibility of a root canal filling cement, as the N-Rickert paste: implantation of round glass cover slips, polyethylene tubes and pellets of the cement. The results demonstrated qualitative and quantitative differences among the methods utilized indicating as a good toll the use of glass cover slips covered by the cement, since they provide good conditions of work, major areas of study, as also facilities in obtaining the specimens for study. The pellets didn't simulate the clinical conditions of the cement and the very small areas of study of the polyethylene tubes don't give definitive conclusions.
