Identification of areas of interest during intraoral scans

A computer readable storage medium, comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:

• receiving a plurality of intraoral images, the plurality of intraoral images comprising a first intraoral image of a dental site;
• performing image registration between the plurality of intraoral images;
• identifying, by the processing device, a first candidate intraoral area of interest from the first intraoral image, wherein identifying the first candidate intraoral area of interest comprises:
• identifying a plurality of voxels in the first intraoral image that satisfy a criterion;
• determining a subset of the plurality of voxels that are proximate to one another;
• and
• grouping the subset of the plurality of voxels into a volume that comprises the first candidate intraoral area of interest;
• determining a value associated with the first candidate intraoral area of interest;
• receiving a second intraoral image of the dental site;
• comparing the first intraoral image to the second intraoral image;
• verifying, by the processing device, the first candidate intraoral area of interest as an intraoral area of interest responsive to determining that a) the second intraoral image confirms the first candidate intraoral area of interest and b) the value is above a threshold;
• and
• providing an indication of the intraoral area of interest, wherein the intraoral area of interest is hidden in one or more views of the dental site, and wherein the indication of the intraoral area of interest is visible in the one or more views.

A computer readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:

• receiving a plurality of intraoral images of a dental site;
• performing image registration between the plurality of intraoral images;
• identifying, by the processing device and based on the plurality of intraoral images that have undergone image registration, a plurality of voxels satisfying a criterion;
• determining a subset of the plurality of voxels that are proximate to one another;
• grouping the subset of the plurality of voxels into an intraoral volume of interest;
• and
• generating, by the processing device, an indication of the intraoral volume of interest, wherein the intraoral volume of interest is hidden in one or more views of the dental site, and wherein the indication of the intraoral volume of interest is visible in the one or more views.

A system comprising:

• a scanner to generate a plurality of intraoral images of a dental site;
• and
