Area of Science:

  • Dentistry
  • Cardiology
  • Anesthesiology

Background:

  • Tooth extraction commonly causes anxiety and elevated blood pressure (BP) and heart rate (HR).
  • Hypertensive patients are at higher risk for complications due to exaggerated BP and HR responses.
  • Effective pain and anxiety management is crucial for this patient group.

Purpose of the Study:

  • To investigate the efficacy of virtual reality (VR) in controlling BP and HR elevation during tooth extraction in patients with hypertension.
  • To test the hypothesis that VR can mitigate the physiological stress response in this population.

Main Methods:

  • A randomized controlled trial involving 96 patients with controlled hypertension undergoing tooth extraction.
  • Patients were assigned to either a VR group or a standard care group.
  • Blood pressure and heart rate were continuously monitored, with mean arterial pressure (MAP) calculated.

Main Results:

  • VR significantly reduced the elevation of mean arterial pressure (MAP) and heart rate (HR) compared to standard care (P < 0.001).
  • These effects remained significant after adjusting for baseline characteristics and surgical procedures.
  • No increase in adverse events was observed in the VR group (P = 0.677).

Conclusions:

  • Virtual reality is an effective tool for managing blood pressure and heart rate during tooth extraction in hypertensive patients.
  • VR helps maintain physiological parameters within an acceptable range, enhancing patient safety.
  • This study supports the use of VR as an adjunct therapy for managing dental anxiety and its cardiovascular impact.
