Getting to the bottom of root canal therapyMarch 8, 2019Anyone who has tried to extract a firmly rooted mandibular canine tooth in a dog or cat has likely muttered the phrase, "There's got to be a better way," (amongst other muttered phrases!) while performing the frustrating procedure. In some cases, there is indeed a better way. Although root canal therapy is not an option for every diseased tooth, it is an elegant way to treat dead teeth and teeth with pulp exposure. Terminology, development, and anatomy Endodontics refers to the study and treatment of the inside of the tooth (pulp) and periapical tissues, the latter of which are located around the tip (apex) of the tooth root. The pulp consists of nerves, blood vessels, lymphatics, and connective tissue. Pulp tissue is found in the pulp chamber of the crown and the root canal of the root. The pulp communicates with the periapical tissues through numerous small openings in the apex of the tooth root called the apical delta. Dental pulp is important for the development of the tooth in a young animal. Cells called odontoblasts continually produce dentin internally throughout the tooth's life. This makes the walls of the root and crown thicker. Recently erupted teeth have walls that …

Before you change the diet…February 7, 2019Naughty Girl is a healthy six-month old terrier puppy who is being fed a complete and balanced commercial growth food. She lives with Bad Boy, a four-year old beagle-spaniel cross who is fed an adult maintenance dog food. Bad Boy is brought to your clinic for a two-day history of vomiting and acting sluggish (or punky). Your physical exam reveals some pain on abdominal palpation and a lab test for canine pancreas-specific lipase is "abnormal," suggesting an elevated lipase level. Your suspicion of pancreatitis is high and, after rehydrating the dog with fluids, you send him home on a fat-restricted therapeutic diet. Is a diet change warranted in this situation? Nutrition textbooks and veterinary nutritionists refer to dietary fat as a "nutrient of concern" or "key nutritional factor" when talking about nutritional management for patients with pancreatitis. However, before automatically switching a patient's diet, conduct a thorough nutritional assessment to get the whole picture of what's happening in the home environment. Performing a nutritional assessment involves collecting information about the patient, the diet, and feeding management (Baldwin, et. al. 2010). This is not a process that involves extra time or work—a nutritional assessment begins with routine information collected about …
How endodontic and restorative crown therapy can help grow your practiceFebruary 6, 2019With today's specializations, the general practitioner can find it a challenge to treat all aspects of a pet's health. Areas like dermatology, behavior, and especially dentistry have seen a dramatic reduction in the general veterinary practice. Referral to specialists is becoming more and more the option and for good reason. By the very nature of their work, specialists have an increased knowledge in their particular field, making referral to them a wise choice, particularly when the referring veterinarian has little to no experience with a specific discipline. That being said, there is room for these specialized disciplines in a general practice. This is especially true when a practice has a veterinary technician specialist (VTS) credentialed in that specialty, and when appropriate time and effort is given to learning it, performing its procedures correctly, and most importantly, relaying that expertise to the client. Endodontic therapy (i.e. root canal therapy) and crown restorations are two disciplines that can be incorporated into the general practice, if only in a limited way and usually at a much lower cost than a referral practice. Single-rooted teeth, such as canine teeth and incisors, can be good candidates for root canal therapy. When adequately learned, endodontic …
Understanding congestive heart failureFebruary 5, 2019Congestive heart failure (CHF) is described by medical professionals as more of a syndrome than a disease. Yet, when pet owners are often attuned to "disease," how can veterinarians best convey what CHF really is to their clients? "Congestive heart failure can result from a variety of different types of underlying heart disease," says Emily Karlin, DVM, Dipl. (cardiology), clinical instructor at Cummings School of Veterinary Medicine at Tufts University. "When we say CHF, we generally are referring to fluid buildup somewhere it should not be, as a result of heart dysfunction. We can see left-sided CHF (fluid buildup in the lungs—pulmonary edema), resulting in cough or trouble breathing, or right-sided CHF (fluid buildup in the abdomen or around the lungs—ascites or pleural effusion), resulting in abdominal distension or trouble breathing. Basically, CHF is a potential outcome of having heart disease." Recognizing signs and symptoms When it comes to differentiating CHF from heart disease, paying attention to clinical signs and symptoms is key. "Asymptomatic, or occult, heart disease is often detected based on physical exam abnormalities—such as a heart murmur, cardiac gallop, or arrhythmia—or sometimes by echocardiographic screening, but the animal is feeling well at home with no clinical …
What makes a good working dog?February 5, 2019The canine labor market is diverse and expansive. Assistance dogs may be trained to work with the visually or hearing impaired, or with people in wheelchairs. Detection dogs may be trained to sniff out explosives, narcotics, or bedbugs. Others even learn to jump out of helicopters on daring rescue missions. Despite the wide variety of working roles available for man's best friend, those jobs can be tough to fill, since not every dog will qualify. Even among those specifically bred to be assistance dogs, only about 50 percent starting a training program will successfully complete it, while the rest go on to be very well-trained family pets. As a result, the wait list for a trained assistance dog can be up to two years. Evan MacLean, PhD, director of the Arizona Canine Cognition Center at the University of Arizona (UA), is exploring ways to identify the best dogs for different jobs—before they start the long and expensive training process—by looking at their cognitive abilities. He is lead author of a study in Frontiers in Veterinary Science looking at whether canines' cognitive abilities can help predict their success as working dogs. While a dog's physical characteristics and temperament are often considered …
Dentistry—A discipline in need of changeFebruary 4, 2019I am writing this article as I travel home from Phoenix, after attending a successful Veterinary Dental Forum (VDF). This event is the official annual meeting of the American Veterinary Dental College (AVDC), Academy of Veterinary Dentistry (AVD), and the Foundation for Veterinary Dentistry (FVD). This year, VDF drew its largest crowd yet, partly due to general practitioners that are filling an educational void by attending lectures and wet labs in the various disciplines of dentistry and oral surgery. In this month's column, and in honor of National Pet Dental Health Month, I'd like to discuss a challenge for the veterinary profession, specifically dentistry training at the veterinary school level. It's not a new problem, and it doesn't exist at every school, but its significance is greater today than ever before, due to the changing needs of successful general practices. Decreasing significance The number of didactic teaching hours available within the veterinary curriculum is not getting any larger. In fact, teaching hours dedicated toward a specific topic are becoming more difficult to obtain due to new specialties, expanding knowledge base, and justifiable shifts in curricular focus to feed not only the IQ, but also the EQ. Ask any small-animal …
