Abstract

Disclosed is a device advantageously usable for dental therapy and examination, which is an elongated bundle of axially extending fibers. The elongated bundle is tapered at one or both of its ends, and the fibers are bonded to each other in places along their lengths so that the fiber bundle is coherent and the fibers define capillary passageways therebetween.
