Artificial intelligence technology based on deep learning has been widely used in the field of computer vision. In medical image processing, convolutional neural networks have good intelligent learning and key information analysis capabilities in the target area, and shows an intelligence level similar to or even higher than that of professionals in segmentation of various medical images. Parotid gland tumor is a common and frequently-occurring disease in oral and maxillofacial surgery, and there are still some clinical challenges for the accurate diagnosis and treatment of parotid gland tumor. In this paper, the author discussed and analyzed the application and prospect of deep learning technology in the intelligent diagnosis and treatment of parotid tumors, hoping to promote the further application and development of artificial intelligence technology in oral medicine
