Quantum-Enhanced Oral Disease Detection Using Hybrid Quantum-Classical Neural Networks

Around the half of the population in the world are affected by oral diseases, making it one of the most common health conditions. Quantum implementation in medical domain has revealed its potential and versatile applicability especially in medical imaging. This paper explores oral disease identification using hybrid quantum-classical neural networks (HQCNN) and quantum convolution neural networks (QCNN). Our work investigates the possibilities of quantum machine learning in processing complicated dental image data and the contributions it can make in oral healthcare. We implemented a hybrid and a pure QNN leveraging Qiskit framework and a whole dataset of annotated oral disease dataset. Our 8 qubit structured QCNN model and 2 qubit architecture of HQCNN model extract the image features by encoding the features into quantum circuits enabling more expressive demonstration employing fewer parameters. The final result showcases that QCNN and HQCNN perform better than CNNs in disease classification and promise better accuracy, generalization and computational efficiency. This experiment highlights a pioneering step in applying quantum inspired models for oral diagnostics, identifying promising avenues for improving oral healthcare worldwide.
