Q

Pulpitis

A

Inflammation within the non-mineralized tooth cavity

17
Q

A

Inflammation of the supporting structures of the teeth (gingiva, periodontal ligament, alveolar bone)

18
Q

Odontogenesis

A

Dental development

19
Q

Polyodontia

A

Too many teeth

20
Q

Pseudopolyodontia

A

Retained deciduous teeth

21
Q

Complications from malocclusion

A

Difficult pretending/masticating food, injury to soft tissues, tooth loss

22
Q

Dental plaque

A

Bacterial biofilm on teeth, loosely adhered to enamel, resistant to saliva, can be BRUSHED away

23
Q

Dental calculus

A

Mineralized plaque (tartar), salivary secretions+Ca carb+bacteria+debris, firmly adhered to tooth, needs to be SCRAPED away

24
Q

Dental carries

A

Cavities, erosions in mineralized tissue of teeth, result of enzymatic demineralization/degradation

25
Q

Odontoclastic lesions

A

Cellular resorptive lesions of teeth

26
Q

Gingival hyperplasia

A

Proliferative/neoplasia resulting from chronic gingivitis/periodontitis in dogs

27
Q

Features of Severe Chronic Periodontitis

A

Gross: Gingival hyperemia/recession, tooth root exposure
Clinical signs: anorexia, choke, nasal discharge
Sequelae: tooth loss, osteomyelitis, (Pain), sinusitis (in EQ)

28
Q

Feline Odontoclastic Resorptive Lesions (FORL)

A

Chronic gingivitis and periodontitis in cats with tooth resorption
30-75% of cats (c. 9 yo)
Bone resorption, lost teeth

29
Q

Pulpitis / tooth root abscess in horses

A

Cause: impacted food in occlusal surface of teeth
Sequelae: sinusitis
Clinical signs: malodorous nasal discharge

30
Q

Types of Stomatitis

A
  • Catarrhal inflammation
  • Vesicular (inflammation)
  • Erosive / ulcerative (inflammation)
  • Granulomatous / pyogranulomatous
  • Suppurative
  • Diphtheritic / pseudomembranous
  • Lymphoplasmacytic
  • Proliferative
31
Q

Inflammatory response to viruses

A
  • Vesicular disease
  • Erosive/ulcerative disease
  • Papillomatous (Proliferative/neoplasia)
32
Q

Inflammatory response to bacteria/fungi

A
  • Abscesses
  • Granulomas/pyogranulomatous
  • Necrosis +/- diphtheritic membranes
  • Ulcers
33
Q

Vesicular Diseases

A

Foot and Mouth Disease Virus
Vesicular stomatitis, swine vesicular disease, vesicular exanthema
Feline calicivirus

34
Q

Foot and Mouth Disease Virus (FMDV)

A

REPORTABLE
Cloven hoofed animals (ruminants, swine)
Vesicles —> erosions —> ulcers —> secondary infection (painful)
Lesions of nose, mouth, feet, coronary band, udder
HIGH morbidity, low mortality, LOSS of PRODUCTION

35
Q

Feline Calicivirus

A

Vesicular stomatitis of cats
Part of Feline Upper Resp Disease complex (+/-associated with FHV)
Lesions: lingual, oropharyngeal vesicles

36
Q

Bovine Viral Diarrhea (Bovine Pesitvirus)

A

Multi-systemic effects (alimentary, respiratory, repro, immune)

Can form erosive/ulcerative lesions throughout alimentary tract without primary vesicles (i.e., non-vesicular) —> direct epithelial necrosis
(Also lymphoid necrosis/immunosuppressive, teratogenic effect)

Ulcerative stomatitis

37
Q

Lumpy jaw

A

Actinomyces bovis (G+ filamentous bacilli)
Route of infection: penetrating wound

Pyogranulomatous stomatitis/cellulitis
Osteomyelitis, osteolysis, reactive bone proliferation (expansion of jaw)
“Sulfur granules” on histology

38
Q

Inflammatory response to foreign body

A

Abscess +/- granuloma/pyogranuloma

39
Q

Craniofacial dysplasia

A
