We made an investigation concerning the general status of patients, especially about the changes of blood pressure, while they are under flap operation. 33 patients (22 males, 11 females) having normal blood pressure and who were diagnosed as chronic marginal periodontitis were chosen as subjects. These subjects recieved initial preparation in advance of flap operation. Blood pressure changes during flap operation were recorded by an automatic sphygmomanometer (UEDA Co. USM-205). The recordings of blood pressure changes were made at the begining of each operational steps, also every five minutes during the operation and at 30 minutes post operation. We chose the value of blood pressure at the point of 15 minutes after relaxed position before the operation began, as the initial value of blood pressure. From above study we have obtained the following results. 1. The use of 2% lidocaine containing 1 : 80000 concentration of epinephirin as the first local anesthesia, increased the systric and diastric pressure meaningfully. The percentage of blood pressure increase were 6.8% and 5.1% respectively. 2. During the operation, both the systric and diastric blood pressure maintained high value as same as its initial value which was taken at the begining of the operation. Furthermore, both blood pressure increased when root planing began but the standard deviation of increased percentage seemed to be wide spreading. 3. Compared to the pressure recorded right after the operation, the systric blood, pressure decreased and diastric blood pressure increased 30 minutes after the operation. But both the systric and diastric blood pressure did not resume to their initial value which was recorded before operation. 4. The avarage increasing rate of the systric pressure was 6.0% and the diastric pressure was 4.3% during the operation.
