The present invention relates to the field of artificial intelligence technology, and discloses an age prediction method and system based on oral panoramic X-rays. The oral panoramic X-ray and the relatively fixed spatial coordinate information of each permanent tooth are used in an optimized YoloV8 to obtain the developmental stage data of each permanent tooth. The developmental stage data of all permanent teeth are digitized and added to obtain the sum of the developmental stages of all permanent teeth (Sum). The oral panoramic X-ray and Sum are then passed together to a classification model TANet to obtain an inference result of the individual's age. Compared to existing age prediction technologies, the use of deep learning's learning capabilities to classify and predict age avoids heavy reliance on Demirjian's judgment criteria and reduces the systematic errors caused by Demirjian's judgment criteria. Compared with the traditional model's huge demand for data volume, the TANet model is more suitable for the age classification task of oral panoramic X-rays. This problem is alleviated by using the pre-trained model vit_b16 and introducing permanent tooth development stage-assisted reasoning.
