ABSTRACT:
Enhanced radiographic detection is provided by an endodontic marking instrument having a high density radiopaque elongate member, thereby enabling a dentist to better identify the location of the instrument in a root canal and the length of the root canal. The high density, high contrast material of the elongate member is a non-toxic, high density, radiopaque, metallic material such as gold, platinum, palladium, silver, tungsten, and the like. The endodontic marking tools of the present invention are distinctly visible on radiographic images in light of the substantial contrast between the high density radiopaque material and the tooth of the patient.
