Tubular device for intraoral examination of rodents

The device consists of a tube with a conical end, a base, and a movable stem. The rodent is anaesthetized lightly with ether and inserted quickly into the tube so that the head extends beyond the opening at the conical end, where cheeks, upper and lower incisors are secured to permit illumination and direct visual or microscopic examination of the palate, molars or gingiva.
