Test 2: 3 oral cavity Flashcards
oral cavity lined by — cell type
stratified squamous
dysphagia
difficulty eating, drop food
Alveolitis/Osteomyelitis
inflammation of bone surrounding the teeth
Stomatitis
inflammation of oral cavity
Cheilitis
inflammation of lips
Glossitis-
inflammation of tongue
Sialoadenitis

Tonsilitis
inflammation of tonsils
another name for deformities
dysplasias
short jaw is also called
brachygnathism
Maxillary Brachygnathia
Brachygnathiasuperior
spontaneous genetic trait
parrot mouth
Brachygnathiainferior
maxilla is longer then mandible
congenitalanomaly(dysplasia)inhorses
wry nose and Brachygnathia superior
another name for cleft palate
Palatoschisis
Palatoschisis- cleft palate
Incompleteaxialfusionofthepalatinebones → directcommunicationbetweentheoropharynx&nasopharynx suckling → aspiration of feed into upper airways
symptoms of palatoschisis
aspiration of feed into upper airways
cleft palate
broncopneumonia
aspiration pneumonia
cranioventral
Pulpitis
inflammationwithinthenon- mineralizedtoothcavity
Periodontitis
inflammationofthesupporting structuresofthetooth
-gingiva, periodontal ligament, alveolar bone
Gingivitis
inflammationofthegingiva
what holds tooth to the alveolar bone
periodontal ligament
Odontogenesis
dental development
ameloblasts form
enamel
Polyodontia =
too many teeth
Pseudo-polyodontia =
retained baby (deciduous) teeth
dental plaque vs dental calculus
plaque- can be brushed away- bacterial biofilm
calculus- needs to be scaled away- mineralized plaque- bacteria, debris, calcium carbonate
dental carries
cavities-
Erosionsinthemineralizedtissuesofthe
teeth(enamel&dentin)
Resultsfromenzymatic demineralization &
degradationofthetoothmatrix
gingivitis can lead to
inflammation→gingival erosion →ulcers →recession and periodontitis (destruction of periodontal ligament) leads to teeth loss
periodontitis
Deep,persistentinflammation→ destruction of the periodontal ligament→ tooth loosening → tooth loss
indogs,chronicgingivitis/periodontitiscanleadto Gingival —
Hyperplasia
periodontitis will present with
gingival hyperemia (reddening)
gingival recession
tooth root exposure
osteomyelitis
sinusitis
anorexia, choke, nasal d/c
FORL
Feline Odontoclastic Resorptive Lesions
chronic gingivitis that effects middle aged cats and causes tooth resorption
— will cause tooth resorption in cats
Feline Odontoclastic Resorptive Lesions (FORL)
oral mandibular fistula
osteomyelitis- bone infection surrounding tooth root
pulpitis
infection in pulp of tooth of horse leads to root abscesses that will break through sinus cavity and cause sinusitis and smelly nasal discharge
epithelial defect above basement membrane
erosive
epithelial defect below the basement membrane
ulcerative
granulomatous reactions will form — cells
multinucleated giant cells
epithelioid macrophages
pseudomembranous looselyadherentaccumulationofnecrotictissue,fibrin,neutrophils
diphtheritic
viruses in the mouth will causes what 3 diseases
Vesiculardisease
Erosive/ulcerativedisease+/-vasculitis
Papillomatous
viral induced vesicle progression
viral infection cause necrosis of cells and form fluid filled vesicles
vesicles will pop- leaving area of erosion
2nd infection will come in and cause damage- break through basement membrane and cause ulcers
foot and mouth disease effect
cloven hoofed- cattle, sheep, goat, pigs
NOT HORSES
FMDV will cause
lesions on nose, mouth, feet, coronary band and udder
low mortality
HIGH morbidity
cause economic loss due to animals not eaten from being painful
feline calicivirus will cause
vesicular stomatitis
lingual & oropharyngeal vesicles →ulcers
co-infection with feline herpes virus 1
Feline Calicivirus often is a co-infection with
feline herpes virus-1
calicivirus cause vesicles and ulcers in the mouth
bovine viral diarrhea will cause — without —
erosion/ulcers without primary vesicles
will attack GI, respiratory, repro, blood
3 different forms
Acute BVD- from infection acquired ex utero
Mucosal Disease- persistent in utero infection “PI calves”
Thrombocytopenic “bleeder” syndrome (no GI dz)
bovine viral diarrhea (BVD) is also called
bovine pestivirus
3 type of bovine viral diarrhea (BVD)
Acute BVD- from infection acquired ex utero
Mucosal Disease- persistent in utero infection “PI calves”
Thrombocytopenic “bleeder” syndrome (no GI dz)
BVD cause — and — necrosis and have — effects
epithelial cell- erosion and ulcers WITHOUT vesicles
Lymphoid- cause immunosuppression
teratogenic- cause abortion
BVD- bovine viral diarrhea
ulcerative stomatitis without vesicle formation
— and — can cause pyogranulomatous lesion in the mouth
lumpy jaw- actinomyces bovis
secondary infections- foreign bodies
—/laryngitiscausedbyF.necrophorum&Trueperellapyogenes
necroticstomatitis
lumpy jaw is caused by
actinomyces bovis- gram + bacilli
opportunistic pathogen through penetrating wound
will cause osteomyelitis- break down jaw and form pyogranulomatous stomatitis/cellulitis
lumpy jaw
caused by actinomyces bovis
cause expansion of jaw and bone proliferation
2 vesicular viral diseases in mouth
FMDV
feline calicivirus
erosive/ulcerative viral disease in the mouth
bovine viral diarrhea (BVD)
no vesicles
2 things that cause pyogranulomatous disease in mouth
lumpy jaw- actinomyces bovis
foreign bodies
