Evaluation of the apical seal obtained with endodontic implant stabilizers and different cementing materials

Preliminary research was conducted to evaluate in vitro the apical seal obtained with endodontic implant stabilizers in conjunction with four different cement sealers. Standard laterally condensed gutta-percha cones and sealer were used as a control. Apical leakage was measured with the use of methylene blue dye solution. Gross leakage patterns resulted from endodontic implants cemented with both zinc phosphate and polycarboxylate. However, leakage appeared notably reduced when the implants were cemented with cyanoacrylate and Kerr Tubli-Seal. Statistical analysis showed that the lateral condensation of gutta-percha cones and sealer yielded the largest proportion of favorable results. Even so, none of the techniques employed was totally effective for obtaining a hermetic sealing of the root canal.
