Abstract: A system for measuring a depth of a periodontal pocket defined by a gap between a tooth and gingiva includes a frame, one camera, and a processor. The frame is configured to be worn by a user. The camera is configured to capture at least one 2D image of an intraoral target area. The at least one 2D image includes a representation of at least a part of the tooth, a gingiva margin defined by a section of the gingiva adjacent to the at least a part of the tooth, and a probe tip when the probe tip is inserted into the periodontal pocket. The processor is configured to receive the captured at least one 2D image and to determine an insertion length of the probe tip in the periodontal pocket. The determined insertion length represents the depth of the periodontal pocket.
