Intravenous sedation was used for dealing with transient hypertension, so-called white-coat hypertension, before dental treatment. Midazolam used as a sedative also has antianxiety effect, and the mechanism is guessed that it minimizes patients' stress, resulting in the stability of blood pressure. The purpose of this RCT is to evaluate the effect of low dose of midazolam on blood pressure and anxiety scale in white-coat hypertensive dental patients.

Group M: Intravenous administration of midazolam at dose of 0.02mg/kg.
1. We select subject from patients for whom the doctor has ordered intravenous
sedation. Inclusion criteria is SBP>=140mmHg or DBP>=90mmHg measuring when the patient sits on dental chair and has settled down for 5 minutes. Informed consent is obtained from the patient.
2. Patient conducts Japanese version of STAI and VAS about anxiety to dental treatment.
3. We take venous line on the upper limb and inject the drug intravenously. We measure blood pressure, heart rate, and oxygen saturation every 2 minutes until 10 minutes after drug administration.
4. 10 minutes later, patient conducts Japanese version of STAI and VAS about anxiety to dental procedure again.
5.We inject an additional sedative agent and the dental treatment is started.
Study duration is from 01/Oct/2010 to 31/Mar/2013.
Group P: Intravenous administration of saline solution at dose of 0.004ml/kg as a placebo drug.
Method is same as group M.
