Relationship between fluoride concentration in enamel, DMFT index, and degree of fluorosis in a community residing in an area with a high level of fluoride.

abstract：:The term "artificial intelligence" (AI) refers to the idea of machines being capable of performing human tasks. A subdomain of AI is machine learning (ML), which "learns" intrinsic statistical patterns in data to eventually cast predictions on unseen data. Deep learning is a ML technique using multi-layer mathematical...
