QTT: AI-based Oral Diagnosis Mobile Application

Project Summary

The QTT team developed the world's first mobile application based on artificial intelligence to provide oral disease self-diagnosis services - E.A.PO. After the user taking the photo of the diseased part of the mouth by smartphone, the APP analyzes oral health data through deep learning, and then provides the user with a diagnosis report of the oral disease and advice on whether or not to see the dentist. In addition, E.A.PO can also help hospital dentists to process patient appointments and consultations in real time, and can display dental presentation information to effectively facilitate hospital promotion and dental information management.

E.A.PO has developed three major functions: 1 Self-diagnosis: Talk with the robot in the APP any time and at the same time, fill in the questionnaire and take pictures of the diseased area with smartphone. The embeded AI will analyze the pictures and questionnaires in real time and identify whether you should see a dentist with diagnosis report issued; 2 Eating habit management: Users can record eating habits on the APP. According to the caries induction index developed by the QTT team, health conditions of the children's teeth can be determined with correction advice provided. 3 Search for a nearby local dentist: The patient can ask at the APP before going to the dental clinic to check the dental treatment and price.
