摘要
Both diabetes mellitus （DM） and hypertension are common in the aged population. The incidence of angiopathies and calcification in pulp vessels is more frequent in DM patients than nondiabetics.1 Some evidences have suggested an interaction between control of blood pressure and pain regulation. Zamir and Shuber 2 found that hypertensive patients had a higher threshold for sensation of pain than normotensive controls in the tooth-pulp electricity test.
