International ClassesA61B 001/04A61B 001/06 AbstractA novel dental instrument is taught which includes both a laser device and an electronic video dental camera. The teachings of this invention overcome the disadvantages of prior art dental laser instruments which do not provide for other than direct viewing of the treatment area by the dentist, as well as the disadvantages of attempting to use such prior art dental laser instruments together with typical prior art viewing devices such as dental mirrors and dental cameras of the prior art. The dental instrument includes a laser device and an electronic video dental camera is provided having a single handle and a convenient shape, thereby being readily manipulated by dentists who are universally familiar with the manipulation of prior art dental tools. The dental instrument includes a handle to be held by the user, a distal portion which is to be placed inside the patient's mouth, a laser light emission port located at or near the distal end, means for transporting laser light from an external laser source to the laser light emission port, and a camera head located at or near the distal end of the device, with the camera head being formed in order to provide a field of view which includes the portion of the patient which is being treated by the laser light emanating from the laser light emission port.Other References
