Dentistry Flashcards
of teeth a dog has
42
what are some developmental conditions of canines
supernumerary teeth
unerupted teeth
retained teeth
what is a dentigerous cyst?
most common tooth association?
treatment?
cyst associated with imbedded teeth - causing pressure necrosis
most commonly associated with imbedded mandibular 1st premolar
extraction and enucleation & submit the lining for biopsy
treatment for imbedded teeth
extraction
treatment for retained teeth?
what is the criteria to leave them?
usually extracted
1. no endodontic dz
2. no communication w/ oral cavity
3. < 5mm in size
enamel hypomineralization
what disease can it cause?
treatment?
endodontic disease
restoration, extraction or serial radiographic monitoring
what is the difference between canine chronic ulcerative stomatitis and periodontal disease
CCUS - mucosal disease
periodontal disease - gingival disease
CCUS
common lesion?
treatment?
kissing lesion
extractions!
can also do immunosuppression/immunomodulators, analgesia (NSAIDs) and home/professional oral care
what are the two types of reactive lesions seen in the mouth?
ulcerative
proliferative
causes of ulcerative reactive lesions
foreign body
chemical exposure
electrical cord injury
osteonecrosis
reactive lesions require ____ for definitive diagnosis
biopsy
when is the only time we see gums recede and bone does not (reveals necrotic bone)
osteonecrosis
what is unique about the treatment for electrical cord injuries?
must stabilize and treat systemically first - NCPE
may take up to 6mo for extent of damage
surgical tx must be delayed
what are some proliferative lesions
sublingual/buccal granuloma
gingival enlargement
papillomatosis
focal fibrous hyperplasia
Sublingual and buccal granuloma “gum chewer” or “tongue chewer” lesions
cause?
treatment?
physical trauma from mastication
excise only if ulcerated
Gingival enlargement treatment
excise
change meds
azithromycin toothpaste
viral papillomatosis treatment
mild case - non
severe case - sx or laser
medical management - immunomodulators or vaccine
focal fibrous hyperplasia
cause?
diagnosis?
treatment?
periodontal disease
biopsy
excise and treat underlying PD
what are the masticatory oral conditions we talked about for “painful opening the mouth”
masticatory muscle myositis
TMJ ankylosis
retrobulbar disease
muscles involved in masticatory muscle myositis
temporalis
masseter
pterygoid
NOT digastricus
differentiate the two phases of masticatory muscle myositis
acute - inflammation, pain, bilaterally swelling, good prognosis if tx started
chronic - fibrosis, non-painful, muscle atrophy, guarded prognosis based on fibrosis
masticatory muscle myositis
diagnostics?
treatment?
CK, 2M muscle Ab test, or CT guided biopsy
Prednisone
TMJ ankylosis
diagnostic?
treatment?
CT
condylectomy or mandibulectomy
analgesia/anti-inflam
what are the masticatory oral conditions we talked about for “painful closing the mouth”
bilateral mandibular fracture
dental disease (supereruption)
TMJ luxation
trigeminal neuropathy
TMJ luxation treatment
closed reduction
open surgical reduction
condylectomy
trigeminal neuropathy treatment
supportive
usually resolves 1-3 weeks
what are the 3 types of odontogenic tumors
peripheral odontogenic fibroma
canine acanthomatous ameloblastoma
odontoma
which odontogenic tumor:
slow growing
osseous or fibrous
originates from periodontal ligament
most common oral tumor in the dog
peripheral odontogenic fibroma (POF)
which odontogenic tumor:
fast growing
irregular surface
locally invasive, doesn’t met
common in rostral oral cavity
canine acanthomatous ameloblastoma
which odontogenic tumor:
developmental tumor seen in young dogs, horses, ruminants
facial swelling
associated with unerupted teeth
has small tooth like structures “denticles”
odontoma
peripheral odontogenic fibroma (POF) treatment
excise
may require whole tooth extraction if recurrs
canine acanthomatous ameloblastoma (CAA) treatment
wide surgical excision (1cm)
Odontoma treatment
surgical removal
non-odontogenic tumors
malignant melanoma
SCC
fibrosarcoma “hi-lo”
cats are naturally missing what teeth
05 on top
05,06 on bottom
what is the most significant predictor of tooth loss
attachment loss (gingival recession and pocketing)
what are unique features of feline periodontal disease
juvenile periodontitis
alveolar bone expansion
super-eruption
juvenile periodontitis treatment
regular dental cleanings
home care
extensive, early extractions
alveolar bone expansion treatment
radiograph monitoring
extract associated tooth
bone reduction at time of extraction
Super-eruption of teeth especially maxillary canines treatment
extraction
clinical signs of feline chronic gingivostomatitis (FCGS)
halitosis
decreased grooming
decreased appetite
inflammation of the caudal oral cavity/palatoglossal folds
feline chronic gingivostomatitis (FCGS) biochemical findings
increased globulins
feline chronic gingivostomatitis (FCGS) treatment
caudal mouth extractions or full mouth extractions + analgesia + nutritional support (Etube)
pyogenic granuloma in cats
most commonly associated tooth?
secondary to what?
treatment?
mandibular 1st molar
trauma from maxillary 4th premolar
excision + extraction of teeth
what is the most common feline oral tumor? prognosis? ddx?
SCC
poor prognosis
osteomyelitis
