A

dogs and sheep

40
Q

Q

What is a common squela to periodontal disease?

A

periodontitis and loss of teeth

build-up of organic matrix composed mainly of bacteria on the exposed tooth surface (supragingival plaque) and in the gingival crevice (subgingival plauqe)

44
Q

Dental calculus (aka tartar)

A

calculus is formed by deposition of salivary minerals on mats of dead bacteria; contributes significantly to periodontal disease

45

Chronic gingivitis

A

leads to periodontitis with resorption of alveolar bone and loose, lost, or abscessed teeth

46
