 Root filling with Soft-Core is easy and provides an exceptional apical seal
The principle behind the Soft-Core Endodontic Obturator is simply a radiopaque plastic carrier covered with thermoplastic gutta percha.
The plastic carrier is available in ISO sizes 20-100.
The technique
- Choose a plastic carrier which will fit slightly loose in the actual root canal.
- Heat the guttta percha in a Soft-Core oven.
- The plastic carrier is sufficiently flexible to negotiate curved canals, and works like a spreader for the gutta percha. It will fill aprox 2/3 of the root filling. The tapered plastic carrier ensures lateral pressure during insertion to assist in filling any lateral canals present with the flowable gutta percha.
- The color-coded handle with the metal insertion pin is removed after insertion in the root canal. This leaves the coronal part of the plastic carrier hollow, which will make future post space preparation easier.

 Size Verifier
The Size Verifier is used to ensure a proper fit in the root canal for the choosen obturator size. The Verifier is made of plastic and has the exact dimension as the same size obturator core. Both the Obturator and the Size Verifier have a rubber stop to indicate the working distance measurement.
Use of the Size Verifier is highly recommended, unless you are using a rotary file system with a taper of .04 or greater for shaping the root canal. In these cases, the Size Verifier is unnecessary since the rotary files have a greater taper, or conicity, than the actual obturator core.
The Soft-Core Obturator is available in following sizes: #20, 25, 30, 35, 40, 45, 50, 55, 60, 70, 80, 90 and 100.
