The first step of root canal treatment for incisors is to open the pulp using a split drill, first use the split drill perpendicular to the surface of the tooth, when the split drill enters the pulp cavity, then use a ball drill to lift upward parallel to the long axis of the tooth, to open the pulp cavity completely, extract the pulp through the extraction needle, take root canal measurements to determine the length of the root canal treatment, use the machine expanding thumbs to perfect the preparation of the root canal, and clean out the infected material thoroughly, so that the root canal wall is very clean and free of any bacterial The walls of the root canals are very clean and free of any bacteria. The root canal is sterilized, the tip is tested, and if the tip is just right, it can be filled with hot cement, which is the entire process of root canal treatment for incisors. After the root canal treatment the incisor will be darkened and dulled and will need to be restored with an upper crown.
