摘要： An absorbent dental device has an inner core roll of absorbent material adjustably telescoped within a hollow cylindrical outer roll of absorbent material. The adjustable positioning of the inner core roll within the hollow outer roll permits adjustably sizing of the device, while the pliant material of the rolls facilitates shaping of the device. The device may be used separately as a fluid and debris absorbing device within the patient's mouth during a dental procedure. The device may also be used as an aspirator cover to prevent damage of the mouth tissues and promote patient comfort while at the same time providing the aspirator with an extension of desired size and shape.

摘要： An elongate, generally cylindrical, hollow cotton roll for use with metal or plastic aspirators or suction tubes for keeping an area dry in medicine and dentistry. The roll has an inner layer of an open mesh fabric which receives the end of the aspirator, a layer of cotton or synthetic roving surrounding the fabric layer, and a layer of braided yarn surrounding the roving to retain same. Also disclosed is a machine for manufacturing such a cotton roll in a continuous length.
