A dental camera is provided which is capable of operating in a wireless mode and a wired mode. A handpiece includes circuitry for generating a signal representing a video image and a first connector. A wireless adaptor module includes a power supply for supplying power to the handpiece, a transmitter for transmitting the signal representing a video image, and a second connector that mates with the first connector when the dental camera is being operated in the wireless mode. A cable has a third connector that mates with the first connector when the dental camera is being operated in the wired mode. With this system, clinical flexibility is afforded to a dental practitioner.
