Jordco, Inc., was established in 1979 by James Johnsen, DMD, and Hal Oien, DMD, while attending

the Oregon Health Sciences University (OHSU) School of Dentistry in Portland, Oregon. Jordco is an acronym for Johnsen Oien Research and Development Company. It not only incorporates the names of the founders, but also includes the basic commitment to continue the research and development of dental products that make procedures easier, safer, and more productive.
During their junior year of clinical training in endodontics, it became apparent to Drs. Johnsen and Oien that the handling of sharp and contaminated dental files was dangerous and lacked organization. From their experiences working in the undergraduate endodontic clinics, the concept of Jordco’s flagship product, the original Endoring® (Figure 1) was formed. The original Endoring® was designed on a napkin, and the early prototypes were constructed with pink denture wax and cast from copper pennies. Early design engineering was often done at the kitchen table, and prototypes were built and tested in the dental school student simulation laboratory.
