the publisher Volume Number This quote from the book of John is inscribed on the lobby wall of the Central Intelligence Agency headquarters in Langley, Virginia, and I think of it often while treating patients In clinical endodontics, as with all science, few things are as important as truth Our essential sworn duty is to “do no harm.” We risk no greater harm to our patients than when we proceed on the basis of assumption, presumption, or habit, without first doing everything we can to ascertain the truth of our patient’s condition Fortunately, we have tools today that allow us to see more, appreciate more, and evaluate more of a patient’s condition than ever before My first epiphany in this realm was while still practicing general dentistry My insatiable quest for continuing education took me to Santa Barbara, California, under the guidance of Dr Cliff Ruddle It was there that I first looked through a dental operating microscope I was literally AMAZED! French author Marcel Proust once observed, “The true voyage of discovery consists not in seeking new landscapes, but in having new eyes.” As soon as I integrated a dental microscope into my general practice and peered through the lenses, I understood the truth of Proust’s wisdom Thanks to the lighting and magnification of the scope, I was seeing the closest thing possible to the truth of my patient’s condition Now I could see, with vivid clarity, every tooth margin I looked, in intimate detail, at things that I saw clinically…but had not really seen Shortly, I came to realize another truth: we cannot treat what we cannot see And the better we can see it, the better we can treat it Proper use of the microscope impacts everyone involved in patient care: the clinician who immediately gains confidence, the assistant (hopefully utilizing the assistant’s binoculars) who can better anticipate and understand the clinical conditions and needs, the office staff who know that their clinicians are providing the most well-informed care possible, and of course, the patients themselves who benefit from potentially reduced chair time, reduced pain and discomfort, decreased recovery times, and less risk of the need for future treatment While attending graduate school at Boston University, my mentor, Dr Herb Schilder, sometimes referred to me as “The Virus,” because I was so excited about new dental technologies — and I was all too eager to share that enthusiasm with my classmates, my teachers, and anyone else who would listen But the truth is that my love affair is not really with technology itself, but with what I can with it And that still holds true today The things that we are able to today with technology in dentistry are truly amazing Without question, I consider the dental operating microscope the single most important piece of technology that I have incorporated into my practice Like the microscope, which I discovered purely by accident, more recently, Cone Beam Computed Tomography (CBCT) has proven to be a practice game changer for me And like the microscope, it has transformed both the way that I practice and the way that I think about truth I never anticipated the impact that visualizing dental anatomy in 3D would have on my staff, my patients, my practice, and me CBCT has literally changed the way that I approach clinical endodontics This technology is the epitome of John’s verse: it represents three-dimensional truth, and the freedom to treat patients confidently, creatively, and effectively because of the truth it provides CBCT allows me to visually strategize the clinical execution of a procedure before I actually it, whether it’s endodontic therapy, a careful manipulation of the Schniderian membrane for a sinus lift, or the placement of a dental implant — either done “free hand” or utilizing CBCT’s DICOM data to create a computer-generated surgical guide Beyond visualizing the anatomy prior to the procedure, having the 3D scan on a large highresolution monitor chairside provides a true representation of the operating space, and an incredible level of pretreatment confidence along with it Procedures that once were difficult and created significant pretreatment anxiety for doctor, staff, and patient are now commonplace and are executed with ease To the benefit of all, with CBCT we can digitally document the entire scope of a procedure, from initial evaluation, through treatment planning, and eventually, years of follow-up This gives us the great luxury of going back to review past cases and learn from our own experiences, as well as to provide extensive treatment feedback to our referring doctors and the colleagues with whom we consult With today’s technologies, endodontic professionals are closer than ever to attaining that ultimate scientific pursuit of truth New tools and ever-evolving technologies add limitless stimulation to the practice careers of those who embrace them, and ultimately set us free in the greatest way imaginable: by giving us the freedom to continue to grow at what we best, for our patients, our colleagues, and ourselves Thomas V McClammy, DMD, MS aka: Clamdawg North Scottsdale Endodontics & Implantology (Arizona) Foundational Dental Seminars Endodontic practice INTRODUCTION Few things are as important as truth November/December 2013 -

I grew up in Northern New Jersey, and would like to say I spent endless summers hanging at the shore, but I actually spent summers working with my father doing construction since the fourth grade I benefited from a liberal arts education and graduated from Lycoming College with honors I attended the University of Medicine and Dentistry, receiving both graduate and postgraduate degrees I also enjoyed being an Associate Clinical Professor for 10 years I started my first practice right out of school and have opened five offices in New Jersey since then Is your practice endodontics? limited to I am often asked if our practice is just limited to endodontics My answer is we are limited to comprehensive endodontics We limit ourselves to root canals, surgical endodontics, facial pain diagnosis, occlusion, TMD, and patients with special needs A complete postgraduate program touches upon many areas of endodontics, and it is up to individuals what they limit themselves to What training undertaken? have you You are never done training and learning Take continuing education courses that are not endodontic in nature Anatomy, microbiology, restorative, and pathology helps you communicate with your peers on a more thorough comprehensive basis Why did you decide to focus on endodontics? So, why endodontics? At first, I thought it was fun, I had an aptitude for it, and loved doing it I had a deep respect for the instructors in my department To this day, I still love going to work How long have you been practicing, and what systems you use? I have been fortunate to be practicing for close to 25 years There was once a time when I use to say: “We have to be able to Endodontic practice this on computers!” Careful for what you wish for Plumber, move over on my speed dial, computer technician, step right in We review radiographs from many different software systems We have been exceptionally pleased with companies such as Adec, Schick, and Planmeca The detail and support we feel has been consistent and dependable Who has inspired you? Professionally, what are you most proud of? On a professional level, I am most proud of my fellow colleagues in the office, both doctors and staff “I’d rather be having a root canal.” Guess what? — you are! We work hard to make our patients want to come back What has been your biggest challenge? I was first and still inspired by my family dentist, Dr Anthony Cipriano I could tell as a teenager he really enjoyed what he did Patients can sense that, young to old That may be the tip of the day The biggest challenge we face is to have others understand that many teeth indicated for extraction can be saved Quality CBCT imaging makes diagnosing and treatment more predictable What is the most satisfying aspect of your practice? What would you have become if you had not become a dentist? We are tooth savers! When told the tooth can’t be saved, nothing is more satisfying then keeping that tooth right where it erupted Origin of facial pain, yes, we have it figured out; let’s put you in the right direction The practice’s scope of treatment expands as well as the opportunity to collaborate with many of our colleagues from medicine to dentistry I was fortunate to choose my profession As a child growing up, I wanted to be an astronaut My career would have ended early; I have to take Dramamine before I go on carnival rides with my daughter What is the future of endodontics and dentistry? The future of endodontics is found in Volume Number Achieve the Optimal Treatment Room with ASI The Cart, With Only One Foot Control The versatility of ASI’s custom integrated cart system allows for infinite positioning of the cart to easily maneuver within close reach during procedures and then out of patient view after procedures Adding a monitor mount creates an intimate environment for both patient education and clinical use Side Delivery An ASI cart positioned at the doctor’s dominant side requires the least amount of tasking movements during a procedure and works efficiently with microscope dentistry Foot Control Placement The foot control tubing of an ASI system can be run underneath the floor through a conduit from the junction box to the patient dental chair The end result creates easy access to the foot control without tubing running across the floor The Junction Box In addition to attractively concealing the standard connections of compressed air, suction and electricity, ASI’s unique in-wall junction box allows computer connections such as video, USB, network and other IT connections throughout the office to be easily organized and safely hidden from view “The ASI Endodontic carts are a great convenience This space saving design allows me to be organized and efficient with only one foot control and without all of the cords draped over my counters.” – Dr Kelly Jones 1-800-566-9953 • asimedical.net PRACTICE PROFILE research and technology Endodontic research has given us a much more comprehensive understanding of microbial infections, biofilm, and anatomy Our practice has been the first to incorporate both CBCT and lasers in many ways to treat our patients Patients are more educated, they want to save their natural teeth, and we have the tools available to us endodontist is twofold Look beyond the tooth Take what you learned in school, and use it to treat the whole patient To make it easier, invest in quality equipment backed by quality companies Do your research Look for a quality CBCT machine, a machine that allows you to study and diagnose the oral maxillary complex, TMJ, and sinus with great detail What are your top tips for maintaining a successful practice? What are your hobbies, and what you in your spare time? Listen to the patient Be fair to the patient Make sure the patient understands what you’re doing and why you’re doing it Communicate with the patient and the dentists Endodontics can be demanding It is best to have distractions to take your mind away from the office So, I became a soccer mom with my wife There is nothing like kids to help you forget about the office for a weekend Typically, when I am asked to lecture across the country, the first place I look for is a National Park to incorporate into our trip It’s a great way to really appreciate what we work for EP What advice would you give to budding endodontists? The best advice that I can give to a budding Endodontic practice TOP 10 FAVORITES LIST My number one most indispensible piece of equipment in my office, our Promax 3D Explaining to patients how their CBCT image has given me the detail I need to help them Being the first to use the Waterlase MD to treat lesions without making a surgical flap Working with the NBA in Africa to help children Treating kids and special needs individuals when they were turned away from other practices Telling patients at a.m that it is normal; everybody calls me at this time to tell me they had a toothache for weeks Having the opportunity to learn from other colleagues while lecturing in different areas of the country Enjoying problem solving and interacting with my colleagues Watching my daughter’s athletic ability and realizing it does skip a generation 10 Finally, being able to hang at the shore Volume Number LEGAL MATTERS Upholding the Endodontist’s Standard of Care Drs Stephen Cohen and Edwin Zinman discuss how to avoid patient distrust W e endodontists were initially trained as restorative (general) dentists Then we extended our studies by completing additional years of post-graduate training to enable us to list ourselves as specialists We are licensed by the state, and recognized by our national and state dental organizations to employ our additional skills to render the highest level of endodontic therapy But from what I have seen in over 40 years of practice, and serving as an expert witness for defense counsel (and yes, plaintiff’s counsel too), is that some of our endodontic colleagues get caught up in legal entanglements — even when they meet the Standard of Endodontic treatment care How does this happen? And how can we avoid it? This can occur if the endodontists fail in their communication skills, also known as informed consent, or postoperatively, which can be akin to abandonment My colleague, Dr Ed Stephen Cohen, MA, DDS, FACD, FICD, is a Diplomate of the American Board of Endodontics and is in Private Endodontic Practice in San Francisco, California He lectures worldwide on endodontics and is the senior editor for all nine editions of the definitive endodontics textbook, Pathways of the Pulp, and a coeditor of the renamed 10th edition Cohen’s Pathways of the Pulp Dr Cohen served as the Chairman of the Endodontic Department, University of the Pacific Arthur A Dugoni School of Dentistry and has continued as an Adjunct Clinical Professor of Endodontics In addition to his academic appointments, Dr Cohen has held leadership positions in many of the major professional and academic organizations in endodontics and dentistry, including as a Director of the American Association of Endodontists and as a fellow of both the American College of Dentists and the International College of Dentists Edwin J Zinman, DDS, JD, graduated from the University of Pittsburgh School of Dentistry and received a Certificate in Periodontics and Oral Medicine from New York University College of Dentistry He also received a JD from University of California, Hastings College of Law He has served on the Journal of Periodontology Editorial Board from 2000 to the present He is a member of the American Academy of Periodontology, American Dental Association, California Dental Association, San Francisco Dental Society, Consumer Attorneys of California, and the American Association for Justice He is currently practicing law in San Francisco, California He has authored many articles and also has served as a teacher and consultant 44 Endodontic practice Zinman and I would submit that we need to consider a new non-legal term for judging ourselves — The Standard of Endodontic Excellence Let’s first remember some of the traditional axioms, e.g., “Patients don’t care how much you know until they know how much you care.” Another axiom: “If you take good care of your patients, they’ll take good care of you.” So how these axioms apply to our endodontists’ practices? We have seen a number of legal complaints filed against some of our wellintentioned colleagues, not always because they provided negligent therapy, but rather patients feel the endodontist betrayed their trust How? Below are just a few examples of what engenders distrust of some patients causing them to write negative reviews on Yelp, sometimes filing complaints with the Department of Consumer Affairs, or even engaging a lawyer to file a malpractice complaint We are all trained to perform microsurgery Our specialty training includes knowledge of the anatomical variations of the inferior alveolar neurovascular bundle So we are surprised and disappointed when there is a legal complaint filed against an endodontist from a patient suffering from permanent dysthesia, anesthesia, or persistent paresthesia With the newer techniques and technologies available today, we wonder why an endodontist would perform periapical surgery on a mandibular posterior tooth without the benefit of a CBCT for treatment planning Sure, years ago we could only count on a panoramic X-ray and periapical films to help us guide patients through the risks, benefits, and alternatives (implant, bridge, maybe just extraction) to periapical surgery on a mandibular posterior tooth — that was then w-a-y back in the 20th Century But for years now, we’ve been able to refine our treatment planning with the benefit of CBCT An endodontist is potentially placing the otherwise trusting patient in harm’s way if he/she recommends and/or performs lower premolar or molar surgery without first reviewing CBCT images Of course, even without CBCT, most surgeries will turn out well — except when they don’t! As today’s health care is undergoing a transformation, providing endodontic therapy is undergoing a transformation as well; this is best illustrated by more specialists functioning in the capacity of independent contractors, providing specialty care in the office of a general dentist When an endodontist provides endodontic therapy in the office of a general dentist, does the endodontist have a microscope readily available? And what about the complete armamentarium of instruments and materials; are they also readily available in the general dentist’s office? Certainly this is possible, but improbable Thus, two levels of specialty care are emerging in endodontics: the higher level in the endodontist’s office and a lower level in the clinical setting of the general dentist There may be a short-term gain of more profit for the endodontist in exchange for compromising the quality of endodontic care that generations of endodontic professors, researchers, and Volume Number LEGAL MATTERS MAX-I-PROBE ® ENDODONTIC/PERIODONTAL IRRIGATION PROBES The irrigating probe confirmed THE BEST in the Journal of Endodontics “ the Max-i-Probe removed significantly

SAMPLE AT WWW.RINNCORP.COM ‘Closed-end’ generic probe Others claim a closed tip, but a microscope may reveal a much different story clinicians worked so hard to establish But our endodontic patients will pay the longterm price of increased retreatment of cases failing If this trend continues, we are undermining the necessity for endodontics to be regarded as a specialty, and we will have sold our souls and ethics by potentially sliding down this slippery slope descending from excellence to mediocrity Just as there is no double standard for endodontics in an HMO setting, there should not be a different standard depending upon the office location where endodontics is provided Endodontists set and uphold the endodontic standard of care, and it should never be compromised for profit.1 After apical surgery, patients receive instructions regarding post-surgical care Some endodontists not reinforce the verbal instructions with written instructions Some endodontists neglect to call surgical patients in the evening to follow-up on how the patients are faring after the local anesthesia has dissipated Patients are Volume Number Max-i-Probe The RINN Max-i-Probe tip is welded closed to protect your patient from fluids expressing past the apex grateful (and pleasantly surprised) when the doctor calls them at home following surgery In case patients have a worry (bleeding, pain, sutures irritating the lip or cheek, paresthesia, etc.) and cannot reach the endodontist by phone, they may become so agitated that they call their general dentist or go to the ER for help Consequently, this now becomes a double loss for the endodontist insofar as being unreachable by the patient (patients feel very put off) and also sowing seeds of doubt in the mind of the referring dentist about the endodontist’s conscientious care for his/her referred patient A worst case scenario is a patient with postoperative paresthesia and/or dysesthesia from an overfill into the inferior alveolar nerve canal (IAN) This otherwise avoidable injury can be reversed with microsurgery in the first 48 hours.2 If the endodontist did not prevent this adverse event with careful CBCT planning, the endodontist misses a second chance by not phoning the patient postoperatively to be alerted, if not alarmed, that an immediate referral to a microsurgeon is mandated Serving our patients to the best of our ability is the most satisfying reward Any extra treatment time in the pursuit of excellence in the long run will more than compensate for the additional time we spend doing our best We will gain the personal and professional satisfaction from our increasingly successful treatment results, fewer retreatments, and less time treating avoidable complications The Standard of Excellent Endodontic Care for our patients will likely be manifested in a greater number of referrals as we distinguish ourselves by always striving to our best and the professional satisfaction of achieving our goal EP References Edelman v Zeigler, 233 Cal App 2d 871(1965) Pogrel MA Damage to the inferior alveolar nerve as the result of root canal therapy J Am Dent Assoc 2007;138(1):65-69 Endodontic practice 45 TECHNOLOGY Endodontics made more efficient with the ScanX Swift™ Dr Howard Golan discusses a different type of imaging technology T echnology has made endodontic treatment faster and more efficient However, there are still parts of the endodontic protocol that cannot be avoided that add time to the procedure Taking radiographs is a fundamental part of endodontics When traditional film radiographs are exposed and processed, there is a unit of time that goes by that the practitioner has to get up from the chair, leave the room, and wait for the X-rays to be exposed and processed Digital sensor technology has significantly decreased this unit of time The instantaneous processing of the digital image allows the practitioner to step out of the room and within minutes return to the procedure No longer does the auxiliary have to process the film in another room, sometimes at the other end of the office, wait for the processing time, either dip or automatic, then return to the practitioner for evaluation However, digital sensor technology does have its negatives First, the sensor girth makes it sometimes very difficult for placement in the patient’s mouth Now compound that by trying to fit this sensor around a rubber dam and clamp As a practitioner who has done his fair share of endodontics, placement of the film is of utmost importance in order to see the apex of the tooth being worked on When Dr Howard Golan is a graduate of the University of Michigan School of Dentistry He completed a general practice residency at North Shore University Hospital on Long Island, New York After his GPR, Dr Golan completed a 2-year Implant Surgery and Advanced Prosthetic Fellowship at NSUH He has maintained a busy private practice on Long Island that he shares with his father, Dr Marshall Golan Dr Golan implemented lasers into his practice in 2004 and has attained his Mastership certification in the World Clinical Laser Institute Dr Golan has been fortunate to be asked to lecture and teach laser-assisted dentistry throughout the United States and internationally He is the co-founder of the Center for Laser Education and is a faculty member with the World Clinical Laser Institute teaching Certification Training Courses for that organization Dr Golan has instituted CAD/CAM technology into his practice for years and has lectured on the subject He is a graduate of the Alleman Center for Biomimetic Dentistry He graduated from Concord Law School and has passed the California Bar Examination, obtaining his license to practice law in that state Dr Golan’s excels in teaching quick and productive integration of laser-assisted dentistry, minimally invasive concepts, and CAD/CAM technology into dental practices He practices and teaches a biomimetic philosophy and is passionate about conserving tooth, soft tissue, and bone 46 Endodontic practice a rubber dam clamp is placed, a rigid sensor can be difficult to place in the right position If it moves or the patient moves it because he/she is uncomfortable, then repeat exposures may be needed A second disadvantage of sensor technology is cost These sensors are expensive, and when they break down, which is inevitable, or they are out of warranty, their replacement cost is high An endodontic clinician has another option that takes advantage of digital technology, reduces the cost in the future, and will not have any placement or exposure issues like one can have with sensors Phosphor storage plates (PSPs) are thin, flexible digital sensors that are exposed similarly to traditional dental film With similar dimensions to film, PSPs allow for ease of placement, due to comparative dimensions with traditional film, and can be used with rubber dams and ring systems Like other digital radiological technology, the dosage required to expose PSPs is less than traditional film Furthermore, the plates are disposable The replacement cost of the plates per the number or exposures per plate end up being similar to traditional film costs The processor for these plates, although an initial investment similar to sensors, has no moving parts and has a lifespan years and years longer than sensors As with sensors, PSP technology can have disadvantages One is the separate processing and exposure mediums Once a PSP is exposed in the patient’s mouth, the PSP is delivered to the processor that is usually in a non-treatment room or hallway with a computer attached Thus, the auxiliary or clinician exposes the PSP, removes his/her gloves, and walks the plate to the digital processor This prevents the instantaneous advantage that sensors have over PSPs However, a new PSP processor has been developed to close the gap between the exposure and the processing The ScanX Swift (Air Techniques) is a one-slot PSP processor that is small enough to fit on a countertop in a dental treatment room Thus, the auxiliary does not need to leave the treatment room after exposing the film Once the plate is

OFD in endodontically treated teeth (OFD + ET) The clinical variables evaluated were plaque (full-mouth plaque score), bleeding on probing, gingival recession, probing depth (PD), and vertical (VAL), and horizontal (HAL) attachment levels Reevaluation was performed 12 months after the surgical procedures Results: Both treatments resulted in improvements in all the clinical variables evaluated Postoperative measurements from OFD-treated and OFD + ET-treated sites showed, respectively, 1.2 +/- 1.2 and 1.3 +/- 1.3mm reduction in PD, 0.6 +/- 0.8 and 0.7 +/- 0.6mm VAL gains, and 0.7 +/- 1.1 and 0.8 +/- 1.6mm HAL gains No significant differences were found between the groups Conclusions: The present findings demonstrate that adequate endodontic therapy performed more than months before surgical treatment does not significantly influence the clinical parameters of healing of human mandibular buccal Class II furcation defects Correlation between endodontic broken instrument and nickel level in urine Saghiri MA, Sheibani N, Garcia-Godoy F, Asatourian A, Mehriar P, Scarbecz M Biol Trace Elem Res (2013) [Epub ahead of print] Abstract Aim: To evaluate the correlation between the presence of separated endodontic instrument inside the dental canal and the nickel (Ni) level in the urine samples of subjected patients Methodology: Same-gendered and near-aged participants were selected and were instructed to collect their urine in sterile nickel-free plastic containers The procedures were carried out in the office, and samples were stored in a low-temperature cooler for day and then transferred to the laboratory for electrothermal atomic absorption spectrometry The level of Ni was measured, and the correlation coefficient was calculated Data were analyzed using t tests, Pearson’s correlation coefficients, and linear regression analysis at a level of significance P
