The necessary items for routine checkup before wisdom tooth extraction are oral examination and taking panoramic film of the mouth. 1. Oral examination: After excluding other diseases in the patient’s body, the main examination is to check the patient’s openness, whether there is inflammation in the wisdom teeth and whether they need to be extracted. If there is normal occlusal relationship of wisdom teeth, they can be retained; if there is obstruction of wisdom teeth, they need to be removed. 2. Oral panoramic film: When the wisdom teeth are judged to be in need of extraction, an oral panoramic film or dental CBCT will be taken to observe the location of the wisdom teeth, the root morphology, and the anatomical relationship with the mandibular neural tube, etc., which will then be used by the surgeon to determine the plan for the removal of the wisdom teeth. In addition, women need to avoid the physiological period when wisdom teeth are extracted; it is not recommended to extract them during the first and second trimester of pregnancy. It is recommended to go to the dentistry department of a regular hospital for consultation.
