Abstract: A method includes receiving a radiograph of a dental site and processing the radiograph using a segmentation pipeline to identify a plurality of oral conditions for the dental site. Processing the radiograph using the segmentation pipeline comprises: processing the radiograph using one or more first models that perform tooth segmentation, wherein the one or more first models generate a first output of tooth segmentation information comprising identifications and locations of a plurality of teeth in the radiograph; processing the radiograph using one or more second models that generate a second output comprising at least one of identifications or locations of the one or more oral conditions; and performing postprocessing to combine the first output and the second output, wherein as a result of the postprocessing each of the one or more oral conditions is assigned to one or more teeth of the plurality of teeth in the radiograph.

Abstract: Provided herein are systems and methods for scoring a post-treatment tooth position of a patient's teeth. A patient's dentition may be scanned and/or segmented. Raw dental features, principal component analysis (PCA) features, and/or other features may be extracted and compared to those of other teeth, such as those obtained through automated machine learning systems. A classifier can identify and/or output the post-treatment tooth position of the patient's teeth.

Abstract: In a technique to assess the blurriness of an image, an image of a face is received, the image including a depiction of lips. A processing device determines a region of interest in the image, wherein the region of interest comprises an area inside of the lips. The processing device applies a focus operator to the pixels within the region of interest, and calculates a sharpness metric for the region of interest using an output of the focus operator. The processing device determines whether the sharpness metric satisfies a sharpness criterion, and one or more additional operations are performed responsive to determining that the sharpness metric satisfies the sharpness criterion.

Abstract: A method includes receiving image data of a current state of a dental site of a patient and processing the image data using a segmentation pipeline to generate an output comprising segmentation information for one or more teeth in the image data and at least one of identifications or locations of one or more oral conditions observed in the image data, wherein each of the one or more oral conditions is associated with a tooth of the one or more teeth. The method includes generating a visual overlay comprising visualizations for each of the one or more oral conditions, outputting the image data to a display, and outputting the visual overlay to the display over the image data.
