Dental feature identification for assessing oral health

A computer program embodied on a non-transitory computer-readable medium and comprising instructions which, when the program is executed by a computer, cause the computer to:

• obtain at least one digital image (1) of a person's oral cavity;
• obtain non-image data (2) associated with the person, the non-image data (2) comprising anamnestic information about the person;
• process the at least one digital image (1) or a representation thereof using a first statistical image segmentation algorithm (101) trained to identify at least one visible segment (3), the at least one visible segment (3) being one of a tooth segment (4) or an oral cavity segment (5), wherein each tooth segment (4) relates to a distinct tooth and its related area within the oral cavity and each oral cavity segment (5) relates to a distinct non-tooth-related area within the oral cavity;
• process the at least one visible segment (3) using a statistical algorithm (103) trained to predict at least one invisible segment (6) based on at least one visible segment (3), each of the at least one invisible segment (6) relating to an area within the oral cavity that is not visible on any of the at least one digital image (1);
• and
• process the at least one visible segment (3) and the at least one invisible segment (6) using a statistical object detection algorithm (104) trained to identify dental features (7) linked to at least one visible segment (3) and at least one invisible segment (6), wherein the statistical object detection algorithm (104) uses the non-image data (2) as input regarding what dental features (7) to look for.
