  2. Names and purposes of instruments (periodontal probe, curette, scaler, explorer, elevator)
    • Periodontal probe: subgingeval, checking presence and depth of pockets (gingeval sulcus depth)
    • curette: subgingeval, removing plaque (scaling and root planing)
    • scaler: remove exterior plaque (crown of tooth)
    • explorer: hook on end of probe, NOT subgingeval, checking for defects in enamel
    • elevator: usually winged, for loosening periodontal attachment of tooth, for extraction (displace tooth from support structures)
  3. Indications for extraction
    • periodontal pocket has reached the apex, stage II perio disease when O won’t do home care, can’t do multiple anesthesia, severe systemic or mucogingeval disease, O preference
    • Stage IV periodontal disease or teeth with less than 20-30% of normal bone height
  4. What can arise from proximity of max 4th PM and M 1 and 2 to retrobulbar space
    damage to optic nerves or exophthalmus from severe periodontitis
  5. Definition of endodontic disease and standard treatments for it
    Disease inside the tooth (pulp tissue).  extraction, vital pulpotomy, root canal
  6. Definition of and treatment for resorptive lesions
    Odontoclastic attack on otherwise normal tooth, extraction or crown amputation based on severity.  Body resorbs tooth root, turns into bone.
  7. Definition of and treatment for gingivostomatitis
    disease cats get, we don’t know why (immune), ulcerated mouth especially towards throat.  Includes mucosa, not just gingeva.  inflammation not around teeth, returns immediately after cleaning.  Remove all the teeth, fixes 80%, then try cephalosporin or glucocorticoids.
  8. Definition of distoclusion and mesioclusion, buccal, lingual, caries, furcation, enamel hypoplasia
    • distoclusion: overbite.  Class II.
    • mesioclusion: underbite, class III
    • buccal: cheek-side surface of tooth
    • lingual: tongue-side surface of tooth
    • caries: cavities.  Show as brown spots on tooth, soft or sticky if a problem. More dogs than cats.
    • furcation: where the roots of the tooth meet, important for multi-root extractions and for gingeval/bone loss
    • enamel hypoplasia: Loss of production of enamel as a juvenile, often due to high fever (distemper).  Tooth is damaged-looking, painful until dentin grows out.
  9. Complications of extraction
    • broken and displaced root tips, can go into nasal cavity or mandibular canal
    • hemorrhage, intra- or post-operatively.  Maxillary, infraorbital and palatine artery all near dental structures, disrupted by disease or surgery. 
    • jaw fracture, usually mandible.  Esp canine and first molar extractions.
    • (oronasal fistula, eye issues)
  10. The oral neoplasias Dr. Buelow discussed

  11. When to use parallel vs. bisecting angle technique in dental radiography (which sections of the dental arcade work with which technique)
    Mandibular molars and premolars for parallel technique, all other teeth with bisecting angle
  12. For either scaling or polishing, no more than 5 sec per tooth, or ?
    damage to the enamel can occur—it’s like a jackhammer.
  13. Differentiate large bowel from small bowel diarrhea

    • small: no increased urgency, polyphagia, melena, large volumes with no effort, weight loss, no mucus
  14. Difference between regurg and vomiting and what each implies about the location of the problem
    • regurg: no effort, comes up immediately after eating, food looks the same as going in.  Problem is upper GI, food not making it to stomach, likely esophageal.
    • vomit: abdominal effort, can be more time between eating and return, food can be digested, may not vomit food.  Problem can be more widespread, lower GI, toxicity, etc.

    Saline, insulin, dextrose/glucose, possibly calcium gluconate to protect heart.
  37. Reason for association of PUPD with dehydration
    Tubules not resorbing water from urine, so even though animal keeps drinking, body is not getting the water it needs. Thirst center continues to be activated by hyperosmolarlity of blood, P keeps drinking.

    decreased renal blood flow
  38. Need for gastroprotectants in renal disease – why, which ones
    acidemia and uremia can cause gastric ulcers. Sucralfate if already ulcerated, famotidine, omeprazole
  39. Why hypertension associated w/ renal disease
    • hyperkalemia caused by urine not being excreted or not exchanging Na for K causes
    • bradycardia, which causes hypotension, which causes sympathetic stimulation causing vasoconstriction and tachycardia, causing
    • hypertension. Dehydration causes lowered blood volume, also causing sympathetic stimulation.
  40. causes of renal tubular disease

  53. Nutrient profile vs. feeding trial (ie, what each one is)
    when new foods want to come on the market, have to prove that they provide complete nutrition. Can do so by chemical testing and proving exactly what nutrients are in the food (nutrient profile) or feeding trial, where at least 8 animals get ONLY that food for 6 months with constant monitoring and blood tests for “signs of deficiency”.
  54. What has to be on a food label (8)

    • feeding guidelines
  55. What RER and MER are, how they relate to each other, how to calculate RER
    • Resting energy requirement vs maintenance energy requirement. Resting is how many calories the animal needs per day just to exist. Maintenance adds in energy for movement/activity.
    • RER = 30(kg) + 70 (for 2-45 kg animals) = KCals OR 70(kg)^0.75
    • MER can be 2 or 3 times that, etc.
  56. Why we calculate DMB (not how to do it, just what it’s used for)
    Dry matter basis. To compare different foods, especially to compare wet to dry food.
  57. The definitions of the basic nutrients (6)
    • water - most necessary, needed for hydrolysis, temp, tissue shape and resilience
    • carbohydrates - monosaccharides, disaccharides and polysaccharides that break down into glucose. Quick glucose source. Dogs need more than cats. Turn into starch or fiber
    • proteins - chain of amino acids, needed to make more amino acids, enzymes, tissues, antibodies, hormones, organs
    • lipids - energy production and fat soluble vitamin (ADEK) absorption, essential fatty acids
    • minerals - any inorganic element in food, macro and micro.
    • vitamins - diagnosis of exclusion. Organic necessary material in diet that isn’t anything else.
  58. What IS the deal with taurine?
    Essential amino acids that cats don’t make on their own. If they don’t get enough of it, they get DCM. Used to be common, but since we figured it out much less common.
  59. Definitions of pre-biotics and pro-biotics
    • pre-biotics are non digestible ingredient that influences that growth and activity of bacteria in colon in a way that helps the animal. Esp fructose/carbs

    • renal disease: increase water, decrease Phosphorus, low protein, adjust K as needed, 1.1-1.4 (RER) for cat, 1.1-1.6 (RER) for dog.
    • cystoliths: pH neutral diet, high water (watch for dalmation/urate, Ca oxalate = toxicity). Not all will respond
  62. How nutritional secondary hyperparathyroidism relates to the lizard’s diet
    Lizards MUST receive Ca supplementation to avoid bone problems like rubberjaw. They do not get enough calcium in their diet, so they are always hypocalcemic (without supplementation), so the parathyroids pump out hormone to resorb calcium and phosphorus from the bones, causing the bones to become weak and mobile.
  63. What cecotropes are and why they’re important
    cecotropes are the night feces of rabbits, which need to be reingested for added nutrients. They come out of the cecum.
