Tooth extraction is the most commonly performed small operation in stomatology, but sometimes it will lead to accidents, which will cause unnecessary loss and pain, and even endanger life.
therefore, before tooth extraction, both physical preparation and psychological preparation are needed.
Many patients have anxiety and fear about tooth extraction. They avoid tooth extraction because of tension and fear, or can’t cooperate with the dentist in the process of tooth extraction, or even have syncope.
before tooth extraction, we should know the following precautions:
In which cases, tooth extraction is not allowed:
If patients are accompanied by other systemic diseases, especially hypertension and coronary heart disease, they may have serious complications, even life-threatening.
it is suggested that in addition to effectively controlling systemic diseases and meeting the requirements of tooth extraction, we should attach great importance to the mental preparation and psychological tolerance of patients.
There are serious cardiovascular disease and hypertension in 180 / 100 mmHg.
the general heart disease patients, as long as there is no manifestation of cardiac insufficiency, can pull out teeth.
But when pulling out teeth, it should be done as follows: do not add adrenaline in anesthetics to avoid tachycardia and induce heart failure; anesthesia is complete, action is light, and adverse stimulation, bleeding or injury should be minimized; anti infection prevention treatment should be given before and after tooth extraction, because the resistance of patients with heart disease is lower, and it is easier to combine infection with normal people.
Haemorrhagic diseases: for example, hemophilia and idiopathic thrombocytopenic purpura, there is an obstacle in the process of blood coagulation in the body, so there is a tendency of bleeding.
bleeding after tooth extraction is difficult to stop, which may cause massive bleeding and lead to life risk.
However, leukaemia patients are prone to infection, and the wound after tooth extraction can also become an infection focus, which leads to serious systemic infection and is difficult to control.
therefore, these patients should be treated conservatively when they are suffering from tooth disease, and tooth extraction is not allowed.
Menstruation, pregnancy and lactation: in principle, women should avoid extraction of teeth during menstruation, because the alveolar may have compensatory bleeding during menstruation.
, however, the removal of loose teeth during menstruation has little impact on patients.
, some ingrained teeth, such as impacted teeth or embedded teeth, should be removed after menstruation.
It has been reported that tooth extraction is the most suitable for women on the 10th day of menstrual cycle. At this time, the wound healing is relatively fast and bacterial infection is not easy to occur.
some people think that tooth extraction is not allowed during pregnancy, because it may lead to abortion.
but a large number of clinical practice shows that tooth extraction is safe in the third to seventh month of pregnancy, and has no adverse effect on pregnancy.
