An imbalance in the continuum with a net demineralization over time results in the initiation of caries lesions. The optimization algorithm employed was the Adam optimizer, at a learning rate of 0.0001, with a batch-size of 32 and batch normalization. Dental caries is a dynamic, preventable, reversible, complex biofilmmediated, multifactorial disease that involves a series of demineralization/neutrality/remineralization of dental hard tissue in primary and permanent dentition. For this pilot study, the trained MobileNet V2 was applied on a test set consisting of 100 cropped PR(s). There are multiple theories for their pathogenesis but contributing factors include a combination of a sugar-rich diet, anatomy, oral cavity microbiome, poor dental hygiene, hyposalivationand time 1,2. In conclusion, a convolutional neural network (CNN) was developed that achieved a F1 score of 0.86 for caries classification on third molars using panoramic radiographs.
