What are carnassial teeth?
|
the upper first premolar and the lower first molar
|
|
|
What are indications for tooth extraction?
|
retained deciduous teeth
interceptive orthodontics severe peridontal disease nonvital teeth/ root exposure pulpitis malocclusion supernumerary teeth impacted abcessed tooth luxation |
|
|
How do you extract a tooth with a single or multiple roots?
|
consider rads to asses root anatomy/pathology
sever epithelial attachement with 11 blade and enter peridontal space use root elevator to work around entire tooth, go deeper until the tooth becomes mobile use extraction forcept assess tooth for complete remoal debride alveolus flush aveolus +/- suture |
|
|
What is pulpitis?
|
discoloration in tooth which may be focal
the older the patient is the less likely the tooth will survive - remove |
|
|
What are the classifications for fractured teeth?
|
enamal infraction - just cracks that stain but no loss in structure
enamal fracture - loss of enamel crown fracture - pulp not expose complicated- crown fracture pulp exposed |
|
|
What is a vital pulpotomy?
|
maintain a viable tooth that will continue to mature
-young animals <24 months recent pulpal exposure less than 48 hours |
|
|
What is a root canal?
|
complete removal of pulp contents than seal apex to prevent bacteria from escaping tooth
done in mature tooth with complicated crown fracture |
|
|
What are causes for oronasal fisulas?
|
dental disease
extractions pressure necrosis from foreign body complications of surgery, radiation therapy trauma |
|
|
How can you sustain good sutures after oral surgery?
|
10 days broad spectrum antibiotics
soft food for two weeks no hard toys re check in 10 days |
|
|
What is Chelischisis?
|
primary palate that extends from lip to incisive foramen of the premaxilla
causes infection and aspiration pneumonia |
|
|
What is palatoschsis?
|
cleft of the secondary palate (hard and soft)
these animals have failure to thrive, have difficulties nursing |
|
|
What are salvage techniques in animals with uncorrectable palate defects
|
acrylic appliances - retainer to seal off fistula
nasal septal button - on disc in nasal cavity, the other on oral cavity |
|
|
What are the most common oral tumors of dogs?
|
malignant melanoma
Squamous cell carcinoma fibrosarcoma |
|
|
What are the most common oral tumors of cats?
|
squamous cell carcinoma (prognosis is guarded to poor)
fibrosarcoma Osteosarcoma |
|
|
What is a central ameloblastoma?
|
tumor of dental tissue
noninducinve mesenchyme not stimulated to produce dental hard tissues |
|
|
What is an odontiogenic tumor?
|
tumor of the dental tissue where inductive mesenchyme is induced to produce hard tissue
can be compound - which contain teeth structures can be complex - no differentiated to resemble teeth |
|
|
What is peripheral odontogenic fibroma?
|
benign tumor that doesn't invade
|
|
|
What is an acanthomatous ameloblastmona?
|
benign tumor that locally invades bone
|
|
|
What is the signalment of dogs with undifferentiated malignant oral tumors?
|
seen in wounds dogs 6-24 months of age with loose teeth and no evidence of peridontal or endodontoc disease
very aggressive tumor with rapid growth and early mets |
|
|
What is the cause of lip avulsion?
|
Shearing trauma
|
|
|
How do you surgically manage lip avulsion?
|
interdental stent sutures to support the weight of the lip
need sutures between tooth roots for whole lip avulsion |
|
|
What is a salivary mucocele?
|
submucosal accumulation of saliva in a non epithelial, non secretory lining
sublingual gland is most common |
|
|
What are the clinical presentations of salivary mucoceles?
|
soft, non painful swelling
-may be painful is in acute inflammatory stage or if a secondary infection is present cervical mucocele is most common ranula under the tongue can cause respiratory distress from swelling? |
|
|
What is marsupialization?
|
resection of all to keep it from healing back up
allows for drainage |
