Abstract

Dentin hassasiyeti (DH) tedavisinde invaziv olmayan en etkili yöntemlerden biri dental iyontoforezdir. Dental iyontoforez, insan sağlığına zararsız mikroamper seviyesinde doğru akımın (DC), özel solüsyon ile birlikte DH olan bölgeye uygulanarak tübüllerin tıkanması prensibine dayalı bir tedavi yöntemidir. Bu çalışmada, DH’nin dişe zarar vermeden uzun süre etkili tedavi edilmesi amacıyla, vücut elektriksel direnci ve polarizasyona bağlı olarak sürekli DC kontrolünün yapıldığı mikrodenetleyici tabanlı dental iyontoforez sistemi (mikroDİS) tasarlanmış ve bir prototip geliştirilmiştir. mikroDİS’te iyontoforez akımı hastanın ağrı eşiğine bağlı olarak 0-500 µA aralığında ve 10 µA hassasiyetle, tedavi süresi ise 0-600 s arasında ayarlanabilmektedir. Deneysel çalışmalara göre; mikroDİS vücut direnç değişimine bağlı olarak gerilimi 0-35 V DC arasında ayarlayarak, 0-70 KΩ aralığında 500 µA, 71-140 KΩ aralığında 250 µA ve 141-280 KΩ aralığında 125 µA sürekli sabit akımı ±1 µA doğrulukta verebilmektedir. Sonuç olarak; vücut direnci ve polarizasyon etkisine karşı duyarlı mikroDİS’in, DH’nin tedavi edilmesine yönelik tıbbi uygulamalar ile bilimsel araştırmaların yapılmasına katkı sağlayacağı düşünülmektedir.

Design and performance review of 0-500 µA continuous DC controlled dental iontophoresis system

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.
