[Study of some physical and biological properties of an endodontic sealer composed of calcium hydroxide].

The authors present a study of the physical and biological properties of a new endodontic cement known as Sealapex. In its composition the presence of calcium hydroxide is introduced in order to induce calcification of the periapical tissue. Our results using glass round cover slips implanted on the subcutaneous tissue of mice indicated a persistent foreign body reaction (60 days). The physical properties studied compared to N-Rickert ciment indicated, a decreased leakage. Adhesivity tests didn't give us significant values. Laboratorial studies and clinical trials are necessary to a complete acceptance of this new ciment in endodontic treatment.

[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.
