PAPER 2

Perusal time: 15 minutes Time allowed: TWO (2) Hours after perusal

Answer SIX (6) questions only. All questions are of equal value. Subsections of Questions are of equal value unless stated otherwise

Question One Refer to the attached dental chart for the four-year-old female domestic short hair breed cat. Discuss the steps involved in a professional dental treatment (dental prophylaxis and periodontal treatment). How would your treatments and homecare plan differ for a client that was willing to do ‘whatever it takes’ compared to one that was willing to do ‘nothing’ post treatment with respect to oral health and plaque accumulation?

Question Two You are about to expand and upgrade your veterinary dentistry services in your practice. How would you market this to your staff and your clients?

Question Three Discuss the principles of exodontia. Describe how you would extract a mandibular canine tooth with a healthy periodontium in a 12 month-old dog. Compare this to extracting a maxillary fourth premolar with a resorptive lesion on the distal cusp in a 12-year-old cat.

Question Four A 13 year old female Siamese cat presents with anorexia. Her diet consists of a commercial canned pet food, she is fully vaccinated and has been an indoor cat her whole life. She has received no dental homecare or professional treatments during her life. On oral examination you notice she has moderate dental plaque and dental calculus build-up on a number of teeth, severe gingivitis as well as several absent teeth. Haematology has been performed and systemic disease has been ruled out. Discuss possible oral causes for her anorexia and how you would diagnose and treat them.

Question Five An 18 month old Corgi breed dog presents with a history of trauma involving the maxillary left canine tooth. The dog’s tooth received a blow from a golf club, which has removed the coronal third of the tooth resulting in pulp tissue exposure of approximately 36 hours duration. Discuss your proposed endodontic management of this case, including treatment options available to the owner, and how you would perform the procedure(s) proposed.

Question Six Your receptionist has just received a telephone call from a distraught Great Dane breeder stating that her best show dog, a six year-old male Australian Champion, has just avulsed his lower left third incisor tooth. The owner wishes to save the tooth and prolong the dog’s show career. Discuss your telephone protocol for this owner prior to bringing the dog and tooth into the practice, as well as your proposed management of this case, including treatment options available to the owner, and how you would perform the procedure(s) performed.

Question Seven An eleven month-old female Staffordshire bull terrier breed dog presents to your clinic with halitosis and bilateral lingually deviated mandibular canine teeth. The owner would like to show the dog but is concerned about its appearance, as well as the hard palate ulcers resulting from trauma from the teeth. There is a normal diastema between the maxillary third incisor and canine teeth bilaterally. Describe the orthodontic treatment options available, how you would perform them and any future complications that may arise from your choices.

Question Eight A four year-old thoroughbred horse presents with a ventral swelling of the left mandible. Discuss your approach to diagnosis, differential diagnosis and treatment options available for each of your diagnoses.
