Developing a device to communication for patients treated in the dental chair and evaluate the efficacy

Sitting in dentist's chair where the patient's mouth is open communication with treating dentist is unlikely to achieve. In this study, during the treatment of patients treated in dentistry, not experience much tension and communicate with the dentist, provide a new device and method and evaluate the effect of this new method. In this study, similar to a tennis ball and a ball inflated with air to be prepared at a suitable pressure, squeezing the ball with varying severity by the patient, audible warning will be given. Give audible warning for measuring changes in pressure, use a portable computer with a special program has been prepared by using DASYLAB software. In the experiments, as the tension of the patient, ball begins to spin with different intensity, thus producing different alarms at different pressures an easier way communication between the dentist and the patient is provided. Key words:Communication, Pressure, Variation, Dentistry, Beep, PIC microcontroller, Dasylab Program.
