Association between high blood pressure and deep periodontal pockets: a nested case-referent study.
ABSTRACT A hypertension screening project was performed jointly at a dental clinic and a primary health care centre. In this report the hypothesis that there is an association between high diastolic blood pressure and deep periodontal pockets was tested. A total of 1,239 consecutive patients aged 35-65 years had their blood pressure measured before the dental examination or had a known hypertension. Information on medical history and tobacco use was obtained by interview and dental status was recorded. Fifty-four subjects had known hypertension and 141 had previously unknown diastolic blood pressure >90 mmHg (cases). For each case an age, sex and tobacco-use matched referent was chosen from those with diastolic blood pressure < or =90 mmHg. Significantly more cases than referents had periodontal pockets > or = 5 millimeters deep. In multivariate analyses the prevalence of deep periodontal pockets was associated with blood pressure status also after adjustment for the small differences between the groups in age, sex, tobacco use and number of teeth. In conclusion there was an association between diastolic blood pressure and prevalent deep periodontal pockets. Whether the relationship is a causal one remains to be explored. Screening for high blood pressure at regularly visits at the dental clinic may give the dental care a new important role in the public health field.

ABSTRACT: The purpose of this study was to investigate the prevalence of apical periodontitis and endodontic treatment in hypertensive patients and control subjects without hypertension. In a cross-sectional study, the records of 40 hypertensive patients and 51 control subjects were examined. Periapical status of all teeth was assessed by using the periapical index score. Apical periodontitis in 1 or more teeth was found in 75% of hypertensive patients and in 61% of control subjects (P = .15; odds ratio, 1.94; 95% confidence interval, 0.78-4.81). One or more root-filled teeth were found in 45% and 39% of hypertensive and control subjects, respectively (P > .0.5). Among hypertensive patients 5.2% of the teeth had apical periodontitis, whereas in the control subjects 4.2% of teeth were affected (P > .05). The percentages of root-filled teeth in the study and control groups were 3.1% and 1.8%, respectively (P > .05). Among hypertensive patients 65% of root-filled teeth had apical periodontitis, whereas in the control subjects 43% of the root-filled teeth were associated with apical periodontitis (P > .05). The prevalence of apical periodontitis and endodontic treatment was not significantly different in hypertensive patients compared with control subjects without hypertension.Journal of endodontics 11/2010; 36(11):1800-4. · 2.95 Impact Factor
