title: [Risk assessment of different grades of hypertension during the treatment of patients with acute pulpitis].
abstract: OBJECTIVE
  To evaluate the vital signs changes, influence factors in different grades of hypertension patients during the treatment of acute pulpitis, in order to obtain the risk prevention measures.
  
  
  METHODS
  In this study, 90 different grades of hypertension patients with acute pulpitis were recruited from February 2014 to February 2015 in the Department of Oral Emergency, Peking University School and Hospital of Stomatology. The information about the patients'general health, oral treatment, life signs of change information was collected. Patients were divided into high risk group, middle risk group, and low risk group (30 patients for each group).
  
  
  RESULTS
  (1) Compared with the preoperative, systolic blood pressure (90%), diastolic blood pressure (80%), heart rate increase (100%) were increased in the high risk group. The increase rates of the middle risk group and the low risk group were significantly lower than those of the high risk group (P<0.01). At the same time, the systolic blood pressure of 1/4 (26.7%) patients in high risk group increased more than 20 mmHg (1 mmHg=0.133 kPa), and the diastolic blood pressure of 2/5 patients in high risk group increased more than 10 mmHg, the difference was statistically significant compared with the other two groups (P<0.05). (2) Compared with the preoperative, the average increase of the maximum peak were increased [systolic blood pressure (18.0 ± 1.5) mmHg, diastolic blood pressure (8.0 ± 1.7) mmHg], the mean of heart rate changes [(7.0 ± 0.3) beats per minute] was also increased in the high risk group, while these two indicators were decreased in the low risk group and the middle risk group. The electrocardiogram (ECG) was changed in 6 cases during the treatment in the high risk group. No significantly changed were observed in the low risk group and the middle risk group. (3) Compared the risk assessment in preoperative with that in postoperative, in the middle risk group, 23 cases were evaluated as medium risk in final evaluation, 6 as low risk, and 1 as high risk (risk assessment increased); in the high risk group, 20 cases were evaluated as high risk, 7 as very high risk, and 3 as medium risk (risk assessment decreased).
  
  
  CONCLUSIONS
  Oral treatment is very safe for patients with hypertension, but the risk factor, target organ damage, and complications will also increase the risk of cardiovascular events in elderly patients during the acute pulpitis treatment. Dentist should take some measures to avoid the risks.
