Extractions are usually done with radiographs because imaging is used to determine the position of the tooth in the jaw as well as the inclination, the distance of the maxillary teeth from the maxillary sinus and the distance of the mandible from the mandibular neural tube.
1. When the tooth is extracted, because each tooth is different, the inclination of the blocked teeth includes vertical block, horizontal block, proximal-medial block, distal-medial block, buccal-buccal block, and lingual-buccal block.
2. Therefore, it is necessary to take a picture to determine the specific situation of the teeth, you can take CBCT (dental 3D CBCT) or panoramic film to watch the anatomical position of the teeth, if it is the maxillary teeth to see its position in relation to the bottom of the maxillary sinus, the mandibular teeth need to look at the distance between its and the mandibular neural tube. This is because the proximity of these teeth to these locations can easily lead to adverse consequences.
Therefore, before tooth extraction film is very necessary, the general oral radiography radiation dose is very small on the human body harm is very low, can rest assured that the shooting, but pregnant women can not shoot during pregnancy.
