Sürekli DC kontrollü dental iyontoforez sistemi tasarımı

Abstract

One of the most effective non-invasive methods in the treatment of dentin hypersensitivity (DH) is dental iontophoresis. Dental iontophoresis is a treatment method based on the principle of occlusion of tubules by applying direct current (DC) with a special solution to DH area at the level of microamper harmless to human health. In this study, for the long-term effective treatment of DH without damaging the tooth, a microcontroller-based dental iontophoresis system (microDIS) is designed, which controls continuous DC depending on body resistance and polarization, and a prototype is also developed. Iontophoresis current in microDIS can be adjusted between 0-500 µA and 10 µA resolution, depending on the pain threshold of the patient, and the duration of treatment between 0-600 s. According to experimental studies, depending on the body resistance change, the voltage is adjusted automatically between 0-35 V DC, and thus continuous constant current of 500 µA in the 0-70 KΩ range, 250 µA in the 71-140 KΩ range, and 125 µA in the 141-280 KΩ range can be given with ±1 µA accuracy. As a result, microDIS, which is sensitive to body electrical resistance and polarization effect, is thought to contribute to scientific researches and medical applications for the treatment of DH.
