✔✔________ disease is the most common disease of companion animals. -
✔✔Periodontal
✔✔Clinical signs of periodontal disease - ✔✔Calculus, gingival pockets, loss of alveolar
bone attachment
✔✔The earliest stage of periodontal disease is _______. - ✔✔gingivitis
✔✔Normal periodontal pocket depth in dogs - ✔✔1-3 mm
✔✔Normal periodontal pocket depth in cats - ✔✔0-1 mm
✔✔Dental probe - ✔✔Used to measure pocket depth
✔✔To avoid damaging the gingiva when using the probe, we should use ____. -
✔✔short up-and-down strokes while walking it around the tooth
✔✔Dental explorer - ✔✔Used to explore tooth topography
✔✔Results of periodontal debridement - ✔✔Remove bacterial plaque, endotoxins, &
calculus deposits; halt disease process
✔✔Dental rinses such as _____ or ______ should be used to kill bacteria in the mouth
before debridement. - ✔✔chlorhexidine, zinc ascorbate
, ✔✔Scalers - ✔✔used for SUPRAgingival removal of tartar
✔✔Ways to prevent damage with ultrasonic scaler - ✔✔Never point tip at 90 degree
angle; keep tip moving; keep water flowing; spend no more than 10 seconds on each
