• a mirror surface affixed to the handle and comprising a reflective surface and a pass through surface, wherein the pass through surface is positioned to transmit light via the pass through surface to the image sensor, and
• a light source configured to emit curing light to cure dental material located on the patient's tooth by emitting the curing light onto the dental material, the dental material being on the patient's tooth and in the area of the patient's mouth visible to the health care provider via the reflective surface;
• a display configured to enable the health care provider to observe the dental material cure on a device that displays the image collected from the image sensor;
• and
• a computing device is configured to determine a position of the health care provider's face within the image and determine, based on the position of the face, an area of the patient's mouth that is visible to the health care provider via the reflective surface,
