 In 1994 George E. Meinig published "Root Canal Cover-up Exposed", which resurrected the outdated studies of Rosenow and Price.Concerns were raised that patients hearing about these studies might view them as new and reliable.A book review in the "Annals of Dentistry" critical of Meinig's book noted Meinig based his ideas entirely on Price's 1923 "Dental Infections, Oral and Systemic", and that Meinig's book suffers from a lack of professional editing, makes unsubstantiated claims, confuses basic terms (such as infection and inflammation), and expands into areas unrelated to the main topic.
