Better dental imaging: techniques and practice
BSAVA Congress Proceedings 2021Authors: Milinda Lommer and Jens RuhnauCone-beam CT in veterinary dental practice: Cone-beam CT offers three significant advantages over conventional intraoral radiography. The first relates to the speed with which images are captured; the patient’s entire head is imaged in a 30-second time frame. With conventional intraoral radiography, a full-mouth series can be acquired in 6-10 minutes in the most experienced hands, and as long as 30 minutes for less experienced staff members. The second, most important advantage of CBCT is the ability to visualize structures that are difficult to evaluate on conventional radiographs. These include the maxillary molar teeth, the palatal root of the maxillary 4th premolar tooth, and rotated maxillary and mandibular premolar teeth in brachycephalic dogs and cats. In addition, CBCT allows evaluation of the nasal cavity, maxillary recess, frontal sinuses, TM joints, and tympanic bullae. Finally, use of specialized software to create 3D reconstructive images of the patient’s skull allows clinicians to better visualize the patient’s overall maxillofacial and dental structures and aids client education efforts. While CBCT is commonly employed to evaluate cases with maxillofacial trauma or neoplasia, we have found it extremely useful for every day periodontal and endodontic cases as well.
Dental radiology projections for three rooted maxillary teeth: For two-rooted teeth we can often get good conclusive radiographs using parallel technique or bisecting angle technique when obtaining pictures, but for the three rooted maxillary teeth (especially fourth premolar and first molar), getting a conclusive diagnosis from dental radiographs can prove to be more challenging. This lecture presents the projections needed to obtain good pictures of both teeth, introducing a totally new projection that is very helpful to evaluate attachment loss and periapical pathology.

Dental management in practice
BSAVA Congress Proceedings 2021Authors: Jens Ruhnau and Claire BloorErgonomics in the dental station for the veterinary surgeon: Ergonomically good positions are very important when doing dentistry, since procedures are often long and numerous in awkward back and head positions. This lecture gives the basic guidelines to sit and work with ergonomically good manners to prevent headache, neck, shoulder and back pain to develop. It covers hand instrument grip, light, units, magnifiers, table and chairs, and give a number of solutions to go home and use immediately or to consider when buying new equipment.
Ergonomics in the dental station for the veterinary nurse: Ergonomics is extremely important in the dental station as the veterinary surgeon may frequently spend significant periods of time operating on individual patients, as well as undertaking multiple procedures per day. This can take its toll on the veterinary surgeon’s health and wellbeing due to the potentially awkward head and neck positions they often adopt throughout these procedures. This lecture provides the veterinary nurse with knowledge pertaining to ergonomics in the dental station to take back and apply in practice immediately, to minimise or eliminate the aforementioned negative impacts on their surgeons. We discuss optimal set up of the dental station considering access to the dental unit, X-ray generator, anaesthetic machine and surgical instrumentation, including the positioning of the table and operating light, and explore the concept of four-handed dentistry.

Dental surgery: difficult extractions – tips and tricks
BSAVA Congress Proceedings 2021Authors: Jens Ruhnau and Milinda LommerDifficult dog extractions – tips and tricks: Canines and carnassials most often cause problems when extracted. Root fractures, flap dehiscence and jaw fractures are among the most frustrating complications in the field of veterinary dentistry. This lectures gives tips and tricks to avoid these complications. Some of them you might know – some of them might be new.
Difficult cat extractions – tips and tricks: Extracting teeth from cats poses many unique challenges, including a small space within which to work, fragile gingival tissues, a thin plate of bone separating the oral and nasal cavities, proximity of the maxillary teeth to the orbit, and tooth resorption. Preoperative imaging (radiographs and/or cone-beam CT) is imperative to assess the teeth and alveolar bone prior to extractions. Excellent lighting, magnification loupes, and specialized instrumentation will facilitate extractions. Specialised instrumentation includes fiber-optic or LED-lit high-speed handpieces with irrigation, small round and tapered diamond burs, small Molt or P24G periosteal elevators, cheek and lip retractors, 0.9-, 1.3- and 2-mm luxating elevators, root tip forceps (e.g. FX-49), 4.75” needle-holders, and 5-0 or 6-0 monofilament suture material on a reverse cutting needle. An open technique with removal of alveolar bone will prevent many root fractures, as will knowing when to perform surgical subgingival crown amputation (aka coronectomy) vs. extraction in toto for teeth with resorption. When root fracture does occur, enlarging the flap, removing more alveolar bone and using a tiny ¼ carbide bur to create a trough around the root will enable positioning of a luxator into the periodontal ligament space that may have previously been inaccessible.

Feline chronic gingivitis and stomatitis: an update
BSAVA Congress Proceedings 2021Author Boaz ArtiFeline chronic gingivitis stomatitis part 1 – what it is and managing expectations: Feline chronic gingivostomatitis (FCGS) is a painful oral mucosal inflammatory disease presented in cats. The observable characteristics of FCGS is ulcerative and/or proliferative mucosal inflammation in the area lateral to the palatoglossal folds with or without gingival inflammation. The cause of feline gingivostomatitis is currently elusive, but it can be inferred that a chronic antigenic stimulation, such as a viral infection, results in an inappropriate immune response. Full-mouth tooth extraction is the current standard of care to treat FCGS. About 70% of affected cats will have significant improvement with this dental procedure, but approximately 30% of cats will not respond and will have a poor quality of remaining life. Non-responding cats will need lifelong medical management and severely affected cats will often be euthanized. Therefore, managing client expectations is a very important aspect of managing the disease. This lecture covers current evidence-based knowledge on FCGS as well as therapeutic approaches.
Feline chronic gingivitis stomatitis part 2 – stem cell therapy: FCGS is an immune mediated oral mucosal disease. In that context, cats affected by FCGS demonstrate systemic elevation of cytotoxic T cells (CD8 cells) and other abnormalities indicating an aberrant immune system. Mesenchymal stem cells (MSC) are multipotent stem cells. MSC reside in most organs and tissues such as bone marrow, adipose, and periodontal ligament. Furthermore, MSC has a profound regenerative ability attributed in part to their ability modulate both innate and adaptive immunity. Hence, a therapeutic approach was designed whereby mesenchymal stem cells (MSCs) capable of immunomodulation and significant regenerative capacity were administered systemically to cats that did not respond to extraction therapy. MSCs immune modulatory properties include decreased T-cell and B cell proliferation and function and altered lymphocytes phenotypes. The efficacy of MSCs for the treatment of non-responsive FCGS has been an ongoing study, for the past 9 years, tested in several clinical trials. In these clinical trials, approximately 60-70% of cats had a positive response rate. This lecture discusses the general concept of MSC immunomodulation therapy as well as the clinical outcome of MSC therapy for cats with FCGS and future directions.

Feline chronic gingivostomatitis: recent updates and future perspectives
BSAVA Congress Proceedings 2021Author Boaz ArtiFeline chronic gingivostomatitis (FCGS), a severe inflammatory oral disease of cats, is characterised by immune-mediated oral inflammation affecting the caudal oral mucosa as well as the gingival mucosa. In the past 10 years, several key studies paved the road towards better understanding of the etiopathogenesis of FCGS and improving treatment options. This lecture focuses on recent discoveries and current understandings in both etiopathogenesis and therapeutic options including stem cell therapy and immune modulation. Moreover, with the emerging field of regenerative medicine, this lecture informs practitioners on the practicability of stem cell therapy for FCGS. Finally, a path from current discoveries towards clinical applications is discussed.
