    Abstract: A camera head of a dental camera for detecting caries in an interdental space has an illuminating device for illuminating a tooth adjacent to the interdental space, which includes an infrared light source. The camera head further includes optics which have an image plane and an object plane, wherein an image sensor is located in the image plane, and the object plane divides the space into two half spaces, wherein a first half space contains the optics and is located in front of the object plane, and a second half space is located behind the object plane, both as seen from the optics. The illuminating device and the optics are designed and arranged with respect to one another in such a way that the illuminating device is arranged in the first half space and infrared light exiting the illuminating device is aimed in the direction of the second half space.
