1. A method of dental treatment comprising:
receiving one or more photo parameters to define clinically acceptable criteria for a plurality of clinically relevant photos of a person's dentition, the clinically acceptable criteria including at least a plurality of clinically acceptable positions and a plurality of clinically acceptable orientations of teeth relative to a camera;
gathering a plurality of image-capture rules to capture the plurality of clinically relevant photos, the plurality of image capture rules being based on the one or more photo parameters;
providing first automated instructions to capture the plurality of clinically relevant photos of the person's dentition using the plurality of image-capture rules;
displaying an overlay of a representation of an outline of the person's teeth over a stream of images of the person's teeth to guide the capture of the plurality of clinically relevant photos in accordance with the image-capture rules;
classifying, using a classifier, the content of the images in the stream of images; and
capturing the plurality of clinically relevant photos with the camera in response to the first automated instructions when the one or more photo parameters are met based on the classifying.
