One embodiment includes provision for the flow of a selected fluid in order to defog and/or clean the camera lens (33). In one embodiment, the camera head (14) includes light sources (32a,b) for illuminating the area to be viewed. In one embodiment, the handle (11) of the dental camera (10) includes means for transporting all appropriate signals and fluids to and from the camera head (14), and, if desired, valves and switching means located on the handle for controlling such communication to the camera head. One embodiment includes a dental camera head (14) which allows a number of attachments to be used, such as a telephoto lens, wide angle lens, relay lens, and transillumination devices. In an alternative embodiment, the dental camera (10) is attached to another dental instrument, such as a dentist's drill (92), thereby allowing video monitoring of the task being performed.
