Abstract: According to an embodiment, a system for measuring a depth of a periodontal pocket defined by a gap between a tooth and gingiva is disclosed. The system includes a frame, at least one camera, and a processor. The frame is configured to be worn by a user. The at least one camera is attached to the frame and 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. The processor is further configured to determine, in relation to the gingiva margin, an insertion length of the probe tip in the periodontal pocket by applying an image processing technique on information obtained about the probe tip in the captured at least one 2D image. The determined insertion length represents the depth of the periodontal pocket.
