How important is oral health in blood pressure management?

This study investigated if oral health was linked to blood pressure (BP) management. The authors found that good oral health was associated with better BP control. 

Periodontal disease (PDD) is a condition caused by inflammation in the tissue surrounding the teeth. It is a long-term condition that can have other effects on the body. PDD can lead to an increase in inflammation around the body. Inflammation can have a negative effect on the heart and circulation (cardiovascular system, CVS). 

PDD has been linked to several CVS conditions including hypertension. Hypertension or high blood pressure (BP) is an important risk factor for CVS events. Some studies suggest that PDD treatment improves BP control. One type of PDD is called periodontitis (PDS). It is unclear if PDS has an effect on BP control in patients with hypertension. 

This study analyzed data from 11,753 patients with hypertension. These patients had a periodontal examination between 2009 and 2014. The authors obtained information on oral health and treatment. Blood pressure management was also analyzed. Systolic (pressure of blood leaving the heart) and diastolic (pressure of blood re-filling the heart) BP were analyzed. 

52.2% of patients had a form of PDD/PDS. SBP was 2.3 mmHg higher in patients with PDS receiving treatment for hypertension. PDS was associated with a 20% greater risk of unsuccessful hypertension treatment. More severe PDS was associated with poorer BP control. In untreated hypertension, SBP levels were 2.8 – 7.6 mmHg higher in patients with PDS. 

The authors concluded that that PDS was associated with poorer BP control.

This study was based on medical records. Important information on PDD/PDS and hypertension was not available. Important information included the drugs used to treat hypertension. 

If you have any concerns regarding BP management and other conditions, please consult with your doctor.
