In terms of cardiac function classification, patients with cardiac function grade ¢£ should be considered as contraindications for tooth extraction, while patients with severe cardiac function grade ¢¢ should also be carefully extracted and appropriate countermeasures should be taken.
(2) Hypertension: simple hypertension, no other complications, such as brain, heart, kidney organic damage, generally can be extracted.
Blood pressure above 180/100mmHg should be treated first.
While paying attention to the blood pressure value, we should also pay attention to the patient’s conscious symptoms, the previous highest blood pressure and the recent fluctuation of blood pressure.
(3) Inflammation and malignancy: When acute inflammation accompanied by cellulitis has not been controlled, cellulitis should be controlled first, and the importance of the infected teeth is second.
However, in order to better control inflammation, the affected tooth should be removed as soon as possible.
The extraction of impacted teeth in acute pericoronitis is traumatic and can lead to the spread of inflammation. It should be removed after the inflammation is controlled.
Both acute gingival infection and acute infectious stomatitis should delay the extraction time.
In patients with malignant tumors, removal of the teeth in the tumor area can spread the tumor, and radical surgery should be performed together with the tumor.
Patients with malignant tumors should complete tooth extraction or treatment at least 7 to 10 days before radiotherapy.
After radiotherapy, the extraction of the middle tooth in the treated area should be taken with caution because radionucrosis may have occurred.
It is generally believed that teeth should not be extracted for 3-5 years after radiotherapy.

(5) Blood diseases including anemia, leukemia, hemorrhagic purpura and hemophilia.
Tooth extraction should be considered contraindicated when there is bleeding tendency and low anti-infection ability.
(6) Hyperthyroidism: tooth extraction can lead to thyroid crisis.
When tooth extraction is necessary, it should be carried out after treatment with basal metabolic rate controlled below +20 and pulse rate not exceeding 100 beats/min.
Anti-infective measures should be taken before and after surgery, and epinephrine should not be added to local anesthetics.
(7) Kidney disease: all kinds of acute kidney disease should delay tooth extraction.
(8) Hepatitis: Teeth should not be extracted during acute hepatitis.

(10) Menstrual period: tooth extraction during menstrual period may cause compensatory bleeding, so it is generally considered that tooth extraction should be postponed.
(11) long-term anticoagulation drugs: the long-term use of low-dose aspirin, such as to consider the risk of drug withdrawal is greater than the harm of hemorrhage after tooth extraction, tooth extraction can usually be kept before medicine, if you want to stop drug should be 3-5 days before surgery, postoperative gums pull can be placed within the iodoform sponges hemostatic, and closely observe no active bleeding can leave.
If withdrawal of the drug can lead to embolism risk, the coagulation function should be carefully evaluated, and the tooth can be extracted if conditions permit.
