Lecture 12: Dentistry
| Question | Answer |
|---|---|
| deciduous teeth | 'baby teeth'; 28 CANINE, 26 FELINE |
| permanent teeth | 42 CANINE, 30 FELINE |
| crown | part of tooth visible ABOVE the gumline |
| root | part of tooth BELOW gumline; made of DENTIN, covered with CEMENTUM |
| pulp cavity | center of tooth that contains nerves and blood supply |
| enamel | outer hard layer of crown; HARDEST substance in the body |
| dentin | between enamel and pulp cavity |
| alveolar bone | bone surrounding the root |
| cementum | holds tooth in place |
| periodontal ligament | stabilizes tooth, must be broken down to extract the tooth |
| gingival sulcus | space between tooth and gingiva |
| dental prophylaxis | procedure for treatment and prevention of periodontal disease, recommended to do BEFORE any signs of advanced periodontal disease; anesthesia REQUIRED for a complete and thorough dental prophy |
| animals with periodontal disease often have | COMORBIDITIES; older pts with health issues that complicate procedure (obesity, heart issues, metabolic disease, epilepsy); recommend PRE-ANESTHETIC workup |
| dental prophy STEP 1 | oral exam; complete while anesthetized, check periodontal pockets, record abnormalities on dental chart |
| abnormal periodontal pockets | DOGS -> >3 mm CATS -> >0.5 mm |
| dental prophy STEP 2 | using hand scaler and/or ultrasonic scaler to remove plaque and calculus above the gumline |
| dental prophy STEP 3 | removal of plaque and calculus below gumline; blunt tipped curette |
| dental prophy STEP 4 | plaque detection; air dry teeth and use disclosing solution (stiks to calculus and allows visualization of missed areas) |
| dental prophy STEP 5 | polishing; use of mildly abrasive fluoride paste to polish teeth and remove micro-scratches that occurred during the dental cleaning |
| dental prophy STEP 6 | irrigation; flushing out sulcus and mouth with water or oral rinse |
| dental prophy STEP 7 | post-prophy exam; complete dental chart, note procedures complete and on which teeth (extraction, gum therapy, etc), add at-home care suggestions |
| caries | bacteria in plaque disintegrates enamel and causes cavity |
| tooth resorption (resorptive lesion) | dentin in a single tooth (or several simultaneously) erodes and eventually becomes irreparably destroyed; most common in CATS, can cause crown to fracture, usually affects PMs or molars |
| furcation | loss of bone around tooth |
| attrition | loss of tooth |
| oronasal fistula | connection between oral and nasal cavities due to tooth root abscess or other infection; nasal discharge, sneezing |
| enamel hypoplasia | cells in young animals affected by high temps, poor nutrition, disease |
| brachycephalic head shape | short nose, wide head; teeth often cramped and may be angled incorrectly, tartar builds up faster, may also have underbite (Persian, Frenchie, Pug) |
| mesaticephalic head shape | medium length head, most common, least amount of dental concerns; Poodle, Labrador, Golden |
| dolichocephalic head shape | long, narrow head; most common type to develop oronasal fistulas in cranial arcade, Dachshund, Greyhound, Collies |
