Title The Dietary Approaches to Stop Hypertension (DASH) Diet Has Been Proven to Lower Blood Pressure and Is a Feasible Approach to Lessen Dental Complications in Patients With Hypertension and Cardiovascular Disease
Clinical Question In dental patients with longstanding hypertension, how effective is the DASH diet at lowering blood pressure?
Clinical Bottom Line The Dietary Approaches to Stop Hypertension (DASH) diet has been shown to reduce blood pressure. Reducing blood pressure may lessen the risk of complications for patients with hypertension and cardiovascular-associated diseases during dental treatment.

Key resultsCompared to the control-group diet, DASH was found to significantly decrease insystolic blood pressure (-5.2 mmHg, 95% CI – 7.0, -3.4; P<0.001) and diastolic blood pressure (-2.6 mmHg, 95% CI -3.5, -1.7; P<0.001).

Comments on
The Evidence
The study included 65 articles for a full-text review and 20 for systematic review and meta-analysis. The authors performed a thorough study. They divided participants into different groups such as women and men and also considered the conditions of the participants (whether they are lean or obese). The participants were further divided into different categories such as stages of hypertension, metabolic syndrome, gestational diabetes in women, and age range. Also, different ways to intervene nutritionally were included. They included studies in different areas of the world. However, biases still may exist because some relevant information was missing from some included articles, and there were no included RCTs done in Europe ; therefore, the results might not be applicable to those who are living in Europe or outside of the US.
Applicability Since general dentists have the chance to educate patients, this information can be used to counsel patients who have uncontrolled hypertension. Though general dentists cannot treat hypertension, prevention would help patients to avoid experiencing other problems such as cardiovascular-related disease. Also, preventing hypertension would lessen many complications during dental treatment involving the use of epinephrine in local anesthesia or dental management of orthostatic hypotension.
