| Research Abstract |
People haven't liked the dental treatment and tried to avoid going to a dental clinic. The main reason of this avoidance was the peripheral nervous pain during dental treatment. Then the dental treatment machine, for example air-turbine and electric handpiece, caused the cutting noise and vibration which were conducted to brain tissue through the cranium. We thought these stimulation caused depression and mental pain of the patients. To clear of the mental change, we observed the brain waves of mind operation.
On the otherhand, we have many old patients who had heart disease and lung disease. So in this study, we measured the heart beats by SpO2 and air-pad sensor, respiratory rate by air-pad sensor and blood pressure by fina-press. And to observe the change of stress and pain, we measured the change of respiration by GSR. To analyze the recorded data, we used LabVIEW.
Under the Helsinki declaration, we had twelve volunteers who understood the object of this study. As the experimental stimulator, we used an ultrasonic scaler (full, 70% and 50% power). To certificate of the change of patient, we recorded the video picture by USB camera.
The results of this study,
1,The pain and stress caused by the scaling lead the change of peak interval length, like R-R length.
2,Air-pad sensor was able to record the body conditions as like as the previous established recorders.
These results supported the possibility which the air-pad sensor could find the change of patient's mind operation and body condition. So we thought this air-pad sensor could detect the sign of body condition and protect the aggravation during the dental treatment.
