Abstract: An indication of the dental health of patients can be observed from the pH levels of their saliva. This work presents a first prototype of a smart Orthodontic Bracket (SOB) for continuous monitoring of pH in mouth. The SOB system uses Iridium Oxide (IrOx) pH sensor with 68.8 mV/pH measured sensitivity and is powered through Near Field Communications (NFC) using a smart-phone from a distance of 3.5 cm. The system resolves pH change of 0.15 within a wide range of pH. The system is encapsulated in bio-compatible Epoxy resin and successfully used to measure the pH in Saliva.
