Take your patients' blood pressure: It could save their life

Feb. 14, 2023
February is American Heart Month. Dental hygienists play an important role in safeguarding patients' vascular health by taking their blood pressure. Learn the steps from Hygiene Edge.

February is American Heart Month. Heart disease is the number one cause of death in the US,1 and it's no news to dental hygienists that inflammation in the oral cavity can exacerbate a cardiovascular condition.

According to the CDC, high blood pressure is a major risk factor for heart disease.2 Uncontrolled high blood pressure can affect the heart and major organs of the body, including the kidneys and brain. Periodontitis and hypertension often occur as comorbidities. A positive linear association between the conditions has been found, which appears to be driven by the severity of periodontitis and mostly affects the systolic blood pressure number.3

It's the standard of care to take blood pressure prior to dental treatment, not only to avoid a medical emergency but also because the oral vascular system is connected to the whole body's vascular system. Blood pressure gives a glimpse at a patient's overall health, allowing us to aid in whole-body wellness and identify risk factors for oral conditions exacerbated by high blood pressure.

In 2017, new guidelines from the American Heart Association, the American College of Cardiology, and nine other health organizations lowered the numbers for the diagnosis as seen in the table4:

Hypertension is a complex multifactorial disease with no simple mechanism entirely explaining the blood pressure rise. If your patient has a high blood pressure reading, make a referral to their physician and educate them about the connection of high blood pressure and periodontitis. Be sure to have a team meeting to discuss your practice policy on blood pressure and make practice policies on:

  • When to take blood pressure
  • When your practice will refer patients to a physician or emergency room for further evaluation 
  • How you’ll take blood pressure (with an automatic or manual cuff) 

Proper blood flow is vital to the whole body's system, including the mouth. Having a healthy oral vascular system is important in prevention and healing conditions in the oral cavity, and it starts systemically. If the arteries and vessels in the oral cavity are unhealthy, this increases patients’ risk factors for oral diseases. Continue to evaluate your patients' blood pressure—it's just a matter of time before you save or improve someone’s life.
