Dr. Steven Cohen has various articles and case studies published over the years.
"The objective of dentistry is to retain the natural dentition as part of maintaining optimum oral health. With recent studies linking oral health to general systemic health, promoting oral health translates to improved quality of life. The discipline of Endodontics encompasses retaining the dentition in the face of diseased pulp and periapical tissues."
"After a 13-hour wait in the emergency room with an elderly family member, we presented a consent form by a first year orthopedic resident during discussion of treatment for two broken bones. The 78-year old female patient in question was assaulted on her morning walk and suffered a broken knee and wrist, among other injuries."
"In the Glossary of Endodontic Terms (7th edition, 2003) published by the American Association of Endodontists, the term "perforation" is defined as: "the mechanical or pathologic communication between the root canal system and the external tooth surface". Within this explanation there is an almost endless list of clinical situations where this aberrant "communication" can lead to root canal treatment, retreatment, corrective surgery and/or extraction."
"Picture this: A small town in the Wild West Frontier. The street is deserted, and the sun is beating down on this dust bowl of a town. Two gunfighters square off for a showdown, each at one end of the main street. At one end is the lawman, wearing the white hat, defending all that is good and honourable for the people. At the other end is the villain, wearing the black hat, who feeds on the weaknesses, and fears of these same people. Hanging in the balance is the moral health of this small outpost of civilization."
"The separation of an endodontic instrument instantly transforms a case, from whatever level of difficulty it was preoperatively, to a new level of severity. Given the variants of anatomy that Mother Nature may have placed in the canals, roots and/or jaw of that particular patient, we now have added an iatrogenic factor. In the quest to develop better instruments and techniques to improve our quality of care, we have developed a "double-edged sword", an instrument that can cut and shape the dentin wall efficiently, and in the blink of an eye, cut into the peace of mind of the operator when it separates.
"At a recent endodontic study club meeting, we had the opportunity to discuss what endodontists often chat about. Included in the discussion were levels of busyness, new techniques and technologies, and the different types of procedures that we are seeing in our day-to-day practices. Before long, it became obvious that the pattern of cases looked incredibly similar and strangely unsettling."
"Dr. Barry Sessle has happily agreed to sit in a dentist's chair for at least the next three years. And in that time, the first holder of the University of Toronto's new Arthur Zwingenberger Chair in dentistry hopes he can help lessen or eradicate tooth pain for all the rest of us who will, sooner or later, have to visit one of his colleagues."
"While retreatment of endodontic therapy has received much attention in recent literature, and new instrument technology and improved optics have made way for greater success in retreating canals, there are still clinical situations that require another approach. It is not always possible for a patient to have his tooth dissembled, then re-assembled, not to mention the stress on the tooth structure itself of crown, core and post removal."
