[Ionomeric vitreous cement for retrograde root filling].
In an in vitro study the sealing properties of materials commonly used for retrograde filling of apicectomized teeth were investigated in extracted teeth and compared with those of ionomeric vitreous cement. Materials tested included: --Heat-sealed guttapercha; --Guttapercha + phosphate cement; --Amalgam; --Standardized ceramic pins (Ulm system); and --Ionomeric vitreous cement. Sealing was established by methylene blue perfusion. Seals produced by heat-sealed guttapercha, guttapercha + phosphate cement and non-gamma-2 amalgam were found to be inferior to those obtained with ionomeric vitreous cement and standardized aluminium oxide ceramic pins.
