Abstract
A dental mirror includes a handle having a lumen, a mirror housing attached to the handle, a mirror cartridge for insertion through a cartridge opening of the mirror housing, a drive shaft rotatably held within the handle, and a film-roller rotatably attached to a film-roller bearing. The mirror cartridge includes a base, a film-roller bearing connected to the base, a film support structure connected to the base, and a film surrounding the film support structure. A distal end of the drive shaft and a proximal end of the film-roller are rotatably linked such that a rotation of the drive shaft rotates the film-roller causing the film to move relative to the film support structure.
