Root canal obturation using Thermafil endodontic obturators in dog teeth.

The technique of using Thermafil endodontic obturators to fill root canals in dog teeth is discussed in detail. Stainless steel carriers coated with gutta-percha were heated and inserted in instrumented canals of dog teeth. The ease of the technique is discussed and obturation efficacy is evaluated. No perfect apical seal was achieved.
