Current endodontic instruments, materials, and drugs, and new techniques for their application.

Technical improvements in endodontic instruments, materials, and drugs and the development of new techniques for their application present a problem for dental practitioners in the selection of materials and methods appropriate to their needs. Claims of "superior" products and "state-of-the-art" treatments only add to the confusion. A review of the dental literature reveals that there is seldom a consensus of opinion on any given subject. Preferences among individuals may reflect a desire for a less complicated, more rapid approach to endodontic treatment. Trends in thought among researchers may offer some direction in the choice between changing concepts and traditional methodology.
