BackgroundThere is consensus on the importance of early detection and treatment of high blood pressure. Dental care is one of few medical services to which a considerable proportion of the general population comes for regular check-ups. We tested the effects of blood pressure screening in dental care centres with subsequent work-up of subjects screening positive in primary health care PHCC.

MethodsAltogether 1,149 subjects 40-65 years old or 20-39 years old with body mass index >25, and with no previously known hypertension, who came for a dental examination had their blood pressure measured with an Omron M4 automatic blood pressure reading device. Subjects with systolic blood pressure readings above 160 mmHg or diastolic above 90 mmHg were referred to their PHCC for a check up. Outcome data were obtained by scrutiny of PHCC and hospital patient records for hypertension diagnoses during the three years following screening.

Results237 20.6% subjects screened positive. Of these, 230 97.1% came to their PHCC within the 3-year follow-up period, as compared with 695 76.2% of those who screened negative p < 0.0001. Of those who screened positive, 76 32.1% received a diagnosis of hypertension, as compared with 26 2.9% of those who screened negative. Sensitivity was 79.1%, specificity 84.8% and positive predictive value 30.1%. The number of subjects needed to screen to find one case of hypertension was 18.

ConclusionsCo-operation between dental and primary care for blood pressure screening and work-up appears to be an effective way of detecting previously unknown hypertension.
