viva question and answers in blood pressure while doing tooth extraction

Discussing blood pressure during tooth extraction is crucial, as fluctuations in blood pressure can have an impact on the procedure and patient safety. Here are 30 viva questions and answers related to blood pressure and tooth extraction:

  1. What is the normal range for blood pressure?
    • Normal blood pressure is typically around 120/80 mmHg.
  2. Why is it important to measure blood pressure before tooth extraction?
    • It helps assess the patient’s cardiovascular health and potential risks during the procedure.
  3. What are the potential complications of high blood pressure during tooth extraction?
    • Increased risk of bleeding, cardiovascular events, and other complications.
  4. How does stress affect blood pressure?
    • Stress can temporarily elevate blood pressure due to the release of stress hormones.
  5. Why is it necessary to inform the dentist about any medications the patient is taking?
    • Some medications can influence blood pressure and affect bleeding during the extraction.
  6. What are the recommended blood pressure levels for safe tooth extraction?
    • Ideally, blood pressure should be below 140/90 mmHg for a safe procedure.
  7. How can a dentist manage a patient with high blood pressure during tooth extraction?
    • Consultation with the patient’s physician, controlling anxiety, and considering alternative sedation methods.
  8. Can tooth extraction cause a sudden spike in blood pressure?
    • It’s possible due to pain, anxiety, or stress associated with the procedure.
  9. Why is it essential to use a blood pressure cuff of the appropriate size during measurements?
    • An improperly sized cuff can lead to inaccurate readings.
  10. How does local anesthesia impact blood pressure during tooth extraction?
  11. What preoperative instructions should be given to a patient with hypertension?
    • Compliance with prescribed medications, avoiding certain foods or substances, and managing stress.
  12. How does the dentist monitor blood pressure during tooth extraction?
    • Regular monitoring using a sphygmomanometer.
  13. Can low blood pressure pose risks during tooth extraction?
    • Yes, as it may lead to dizziness, fainting, or other complications.
  14. What role does the dental assistant play in managing blood pressure during the procedure?
    • Assisting in monitoring the patient’s vital signs and notifying the dentist of any abnormalities.
  15. How does epinephrine in local anesthesia affect blood pressure?
    • It can cause a transient increase due to its vasoconstrictive effects.
  16. What precautions should be taken for patients with a history of cardiovascular diseases?
    • Thorough medical history review, consultation with the physician, and careful monitoring.
  17. Why is it important to have an emergency protocol in place for patients with high blood pressure?
    • Rapid response to any unforeseen complications, such as hypertensive crisis.
  18. Can controlled hypertension be a contraindication for tooth extraction?
    • Generally not, but close monitoring and collaboration with the patient’s physician are crucial.
  19. What lifestyle modifications can patients with hypertension adopt before tooth extraction?
    • Healthy diet, regular exercise, stress management, and compliance with prescribed medications.
  20. How does the supine position during dental procedures affect blood pressure?
  21. Is it advisable to proceed with tooth extraction if the patient has uncontrolled hypertension?
    • Consultation with the patient’s physician is necessary, and the procedure may be postponed until blood pressure is well-controlled.
  22. Why is it important to obtain a baseline blood pressure measurement before the extraction procedure begins?
    • To identify any significant changes during the procedure.
  23. Can the use of nitrous oxide in sedation impact blood pressure?
    • Yes, it can cause a mild decrease in blood pressure.
  24. What signs indicate a hypertensive crisis during tooth extraction?
    • Severe headache, blurred vision, chest pain, and shortness of breath.
  25. How can the dentist effectively communicate with an anxious patient to prevent a rise in blood pressure?
    • Clear explanations, reassurance, and the use of calming techniques.
  26. Can tooth extraction be performed if a patient is taking anticoagulant medications?
    • In consultation with the physician, adjustments to medications may be necessary.
  27. What postoperative instructions are important for patients with hypertension?
    • Monitoring blood pressure at home, reporting any abnormalities, and adherence to medications.
  28. How does the duration of tooth extraction impact blood pressure changes?
    • Prolonged procedures may lead to increased stress and potential blood pressure fluctuations.
  29. Can a patient with a history of heart attack undergo tooth extraction?
    • In consultation with the cardiologist, special precautions may be needed.
  30. Why is it crucial to document blood pressure readings and any interventions during tooth extraction?
