Abstract: A system for self-imaging a body portion includes a self-imaging device and an ancillary device that is attachable to the self-imaging device. The self-imaging device has a base member, a camera located within the base member and a guide element for transmitting light along a path extending between the camera and an exposed tip of the guide element that opens out of the self-imaging device at a given side of the device. The ancillary device is arranged to attach to the self-imaging device at said same given side while substantially not obstructing incoming light arriving towards the self-imaging device from being transmitted via the guide element towards the camera.

Abstract: A dental minor system has an axis and is arranged to detachably receive minor heads at its distal axial side. The system includes a threaded internal passage and an airflow nozzle. The threaded internal passage is arranged to receive each time a threaded member of one minor head and the airflow nozzle is rotatable about the axis in order to align an airflow emitted by the nozzle against reflecting surface of the mirror head.

Abstract: A removable intraoral lighting device which can be assembled to many various kinds of dental tools, including a main assembly, containing a miniature and powerful light source, fed from an electric power supply. The main assembly has an external geometrical structure which enables connection to a dental tool, such as a saliva suction device. The removable intraoral lighting device can also include one or more clips for clipping an electrical wire, if necessary, to the dental tool. The scope of the invention includes a method of connecting the removable intraoral lighting device to the dental tool, freeing the dentist's and the dental assistant's hands, and using it as an internal source of lighting a patient's oral cavity during dental treatment.
