Abstract:

A cushion for dental film cartridges and a method for forming the same are disclosed. The cushion comprises first and second layers of foam or a like material bonded together about their common periphery and having a central opening passing therethrough. The foam cushion is installed about the periphery of a film cartridge such as those commonly used in dentistry to facilitate x-raying of the teeth. The foam cushion surrounds and covers the typically hard and sharp edges of the film cartridges to prevent discomfort and pain due to abrasion of the gums and soft mouth tissue.
