Detecting white spot lesions on dental photography using deep learning: A pilot study
OBJECTIVES: We aimed to apply deep learning to detect white spot lesions in dental photographs.METHODS: Using 434 photographic images of 51 patients, a dataset of 2781 cropped tooth segments was generated. Pixelwise annotations of sound enamel as well as fluorotic, carious or other types of hypomineralized lesions were generated by experts and assessed by an independent second reviewer. The union of the reviewed annotations were used to segment the hard tissues (region-of-interest, ROI) of each image. SqueezeNet was employed for modelling.
