The Effects of Overfilled Polyethylene Tube Intraosseous Implants in Rats.

Abstract

Polyethylene tubes obturated flush at one end and overfilled 2 mm at the opposite end with unset Grossman's cement and gutta percha were implanted in rat tibias. Microscopic evaluation of the specimens revealed that (1) the gutta percha, Grossman's sealer, and the polyethylene tubing are well tolerated by rat intraosseous tissue; (2) a canal overextended 2 mm beyond the apex with Grossman's cement and gutta percha produces an early mild-to-moderate inflammatory response which resolves by the 30 day interval. The overfillings did not significantly compromise the healing of rat intraosseous tissue. (Author)
