Comparison of cold GP/sealer and resin bonded obturation techniques in canine teeth in dogs.

An in vitro study compared two obturation materials in the canine teeth in dogs. The teeth were instrumented with rotary instruments and obturated with either gutta percha and a sealer or resin-based materials, utilizing the gutta percha apical plug/master cone technique. Radiographs were used for evaluation of the overall appearance of the finalfill. A modified apical dye leakage method was used to evaluate the ability of each material to provide an adequate barrier to apical leakage. When comparing the two obturation materials, the differences in the radiographic appearance scores and the apical dye leakage test results were not statistically significant. The rate of apical leakage is comparable to other obturation methods that have been reported. The use of a rotary system in conjunction with the gutta percha apical plug/master cone technique is valid for the endodontic treatment of indicated teeth.
