DentalEZ, a member of the DentalEZ Group, produces dental operator systems, including cabinets, patient chairs and delivery equipment used in the dental office. The company was established as Den-Tal-Ez Manufacturing in 1958 by Des Moines inventor John Naughton, who collaborated with Dr. John Anderson to develop his now-famous J-Chair. By allowing the dentist to sit next to a reclined patient, the chair greatly reduced the strain on the dentist's neck and back while enhancing the comfort of the patient. The 100,000th J-Chair, once displayed at the Smithsonian Institution, now resides at the Dr. Samuel Harris National Museum of Dentistry in Baltimore. DentalEZ is located in Bay Minette, Ala.
