RESUMO
Dr. William Ben Johnson introduced the contemporary use fo core-carrier technology for root canal obturation in the late 1970s. This technology has undergone multiple enhancements since its commercial introduction in the early 1990s and has provided a unique clinical treatment regimen for clinicians globally. However, the very roots and evolution of this technique can be traced to the later 1800s, exhibiting a torturous and fragmented history until Dr. Johnson's creativity and impetus brought it the the forefront of root canal obturation techniques. Dr. Johnson received the Inventor of the Year award in Oklahoma for these innovative accomplishments.

This article provides historical background on the development of resin-based dental restorative materials. With an understanding of the evolution of these materials, clinicians can better appreciate both the complexity of and similarities among the wide variety of resins and polymerization techniques available today. Common problems associated with the use of resin-based materials are explained, and more advanced resin-based systems currently under development are briefly reviewed.
