People who are usually above the age of 60 are called elderly. As these people grow older, the functions of all organs of the body are declining, resulting in a decrease in the compensatory and self-regulatory capacity of all vital organs, which affects their psychological and physiological tolerance. If the elderly population exceeds the patient’s psychological and physiological tolerance due to fear, tension, dread, trauma and exertion during tooth extraction, risks will occur. Such patients should pay attention to the assessment and prevention of risks during tooth extraction. Possible risks of tooth extraction in the elderly population 1. The elderly population is prone to hearing and comprehension loss due to their age and mobility, and are prone to anxiety and irritability when seeking medical treatment, causing symptoms such as increased blood pressure and increased heart rate, which may induce the occurrence of cardiovascular and cerebrovascular diseases. 2. Elderly people have increased sensitivity to pain, and the pain during the injection of anesthetic drugs and tooth extraction can cause tension and fear in the elderly. 3. As the liver and kidney function of the elderly decreases, the metabolism of anesthetic drugs in the body is slow, and the injection of anesthetic drugs into the blood can lead to an increase in blood concentration per unit time, causing an overdose reaction. When anesthetic drugs containing epinephrine are introduced into the blood, it can cause epinephrine reaction. 4.The elderly population is often accompanied by osteoporosis and laxity of the temporomandibular joint capsule ligaments, and violence and irregular operation can lead to alveolar bone or temporomandibular joint injury. 5.The sensitivity of the pharyngeal reflex is reduced in the elderly population. During the operation, the airflow of the handpiece and the spray of water stimulate the pharynx, which can cause choking and coughing of the patient. Intraoperative tooth dislocation slips into the pharynx and can be accidentally aspirated into the airway. 6.Sudden movement of the head or limbs caused by tension and fear during the operation leads to misinjury of the surgical instruments to the surrounding tissues. 7.Overexertion caused by prolonged surgical operation, beyond the patient’s psychological and physiological capacity and the corresponding systemic reaction. 8.Rapidly raising the chair position after surgery can lead to postural hypotension and transient cerebral ischemia, causing the occurrence of syncope. 9.The gastrointestinal function of the elderly population is reduced, and preoperative medication may cause stomach discomfort or flatulence. 10.The resistance and coagulation mechanism of the elderly population are reduced, which may lead to postoperative infection and bleeding.
