Abstract
Abstract A periodontal probe tip for attachment to an elongate handle includes a disposable, non-metallic probe tip device having a measuring tine with markings thereon for measurement. The tip device includes a smooth, cylindrical connecting shaft to which the handle can be detachachably attached for use of the probe. The tip device is preferably made from strong, flexible nylon such as nylon 6. The preferred measuring tine has color bands for measuring distances. The preferred bands are 2 to 3 mm across. The probe tips can be individually packaged and sterilized in a package having a paperboard backer and a transparent plastics cover sealingly attached to the backer.
