WaveOne Gold™ GuttaCore is an obturator with a crosslinked gutta-percha carrier enabling warm gutta-percha to be delivered without leaving a plastic carrier in the canal. Retreatment is thus simplified. Warm gutta-percha flows three-dimensionally throughout the entire canal system with the ease of a single insertion. Same color code as the file. 4 sizes (small, primary, medium, large). Choose the GuttaCore size of the same size as the last WaveOne Gold file taken to working length. GuttaCore Obturators are heated at GuttaCore Obturator Oven or ThermaPrep 2 Obturator Oven. Brush a very light coating of AH Plus Jet sealer to the canal wall with the paper point and use an additional absorbent point to remove any excess sealer.
