Abstract |
The purpose of this study was to develop the wireless pH telemetry lasting longer than 24 hours in the mouth to overcome the limits of conventional wire telemetry previously used for salivary and plaque pH measurement, and to assess its effectiveness. We developed a wireless pH telemeter which can measure and store the pH profile data during more than 24 hours. It was composed of intraoral part; pH sensor of antimony electrode, battery and microprocessor for data storage, and extraoral part; control/data receiver and data analyzing software which was newly made for this device. After inspecting wireless electrode for accurate measurement, it was attached to the removable intraoral appliance and delivered to the volunteer who was told to wear except brushing time, retrieved after 24 hours and finally the pH profile data was extracted and analyzed. When compared with conventional wire telemetry, this device showed similar results and induced less discomfort to examinees. The data showed pH changes at same time when examinees ate various scheduled foods and beverages. With this method it became possible to accurately measure pH changes within mouth for long time in accordance with individual's lifestyle, definitely reducing the discomfort inflicted to the examinees' life. |
