Historical Perspectives on the Evolution of Root Canal Sealer/Cements.

Abstract

Various forms of sealing cements have been used in root canal procedures since the mid-1800s to create an impervious seal of the root canal system. In the process both entrepreneurs and charlatans have risen to the challenge. During the first half of the 20^th century, significant activity in this realm was realized, which set the standards for the evolution of contemporary materials and applications.
