った。However, in the above-mentioned conventional root canal filling device 11, since a plurality of gutta-percha points are inserted into the root canal, not only are cavities easily formed between the gutta-percha points. However, with the method of filling the softened gutta-percha points against the side wall of the root canal, it is difficult to fill the root apex, the curved part of the root canal, and the side branch reliably and in a dense state. In the void that is not filled in
There was a possibility that tissue fluid would flow in and cause a lesion. Further, since the gutta-percha point is directly heated by the flame, it is difficult to control the temperature, and there is a risk of causing burns in the oral cavity.
