He closed his doors to hundreds of patients at the age of 75. He loved working with postgraduate and graduate students and would travel to universities throughout the USA to give seminars and to learn about those young dentists who were aspiring to careers in Endodontics. He would thrive on the en- ergy he obtained during these encounters.

Dr Blayney believed that the intelligent practitioner could not accurately diagnose the pulpal status if he did not understand the inflammatory changes James Roy Blayney 1889 – 1980 experienced by the pulp in response to deep carious lesions and the restorative procedures. Although his concern was justified, the concept of focal infection had not been eliminated from the concept of isolated areas of inflammation in the pulp, or for that matter, from the spread of “chronic root end infection” from one tooth to another. His third essential factor was directly connected to the second: pathologic processes were common in the periapical tissues subsequent not only to pulpal inflammation, but also to root canal treatment of both the vital and non-vital tooth. Dr Blayney thought Although more prominent for his pioneering research the dental profession had been severely misinformed in the area of fluoridation, Dr Blayney contributed about granuloma formation.
