Verstraete self assessment review Flashcards
What is the dental formula of the primative carnivore
3143 (44 total)
Which teeth in cat are reduced in number
Max 1st premolar, Mand 1st ad 2nd premolars, Max 2nd molar and mand 2nd and 3rd molars
dens sectorius
carnassial teeth, shredding and cutting teeth
What diagnostics should be done with FCGS
biopsy of oral tissue, complete scale, polish and oral exam
how should a FCGS cat be medically managed
plaque control, and or suppression of immune response
What dose of methylprednisolone is recommended in FCGS
15 - 20 mg per cat sq every 3 - 6 weeks
The bulk of most teeth is composed of ___, what is the main component of this substance?
Dentin, calcium hydroxyapatite
primary dentin
- circumpulpal + mantle
- laid during formation of crown and root
-before eruption
secondary dentin..
- normally formed throughout adulthood
- produced more slowly than primary dentin
- formed after tooth eruption
tertiary dentin
reparative dentin
irreglar dentin formed in response to abnormal stimuli - reactionary dentin
Dentin is formed by
odontoblasts, cells lining the pulp cavity
How is dentin formed
odontoblasts lay down collagenous matrix known as predentin, which mineralizes and forms dentin
What technique is used to improve adhesion of composite resin restorative to tooth?
- mechanical interlock
- Enamel should be etched with phosphoric acid
- Dentin may or may not need etching
- apply bonding agent
- apply unfilled resin and light cure
How long should enamel be etched for
30 - 60 seconds
What is purpose of “etch”
- remove smear layer
- open dentinal tubules
-allowing improved penetration of restorative
over-etching
- destroys integrety of the dentinal tubules
- weakens bond strength
purpose of bonding agent in tooth restoration
-create link between enamel and dentin (hydrophilic) and the dental adhesive resins which are hydrophobic
What is a float?
used to remove sharp enamel points from buccal maxillary teeth and lingual mandibular teeth and to correct abnormalities such as tall teeth, hooks, ramps, and breaks and to round mesial aspect of second premolars
If cat has regurgitant systolic murmur, heard best over sternum and a gallop rhythym, what type of preanesthetic work up should you do?
- CBC, chem, UA,
2. cardiac work up with EKG, Echocardiogram, BP and thoracic rads
What heart condition can this cat possibly have?
Mitral regurg,
cardiomyopathy, and congenital heart defect and endocarditis
gingivectomy
excisional procedure to remove soft tissue wall of periodontal pocket
Methods of gingivectomy
- gingivectomy knives
- cold steel surgical blade
- electrosurgery
- laser
- round bur
How fast does epithelial migration over gingival wound occur?
one day for every 0.5 -1 mm covered
when is a gingivectomy recommended
- pseudopockets
- gingival hyperplasia
When is it contraindicated to do a gingivectomy?
- infrabony defects where incomplete pocket removal and reverse architecture would result
- narrow band of attached gingiva
-bone overgrowth is the problem
What is the membranous bulge lingual to the 1st mandibular molar on a cat mouth?
Molar or lingual salivary gland
order from hardness to softest
-porcelain
enamel
gold alloy
non-precious alloy
amalgam
dentin
porcelain>non-precious alloy> enamel> amalgam> gold alloy. dentin
What is order of weakness of gold, steel, titanium, nickel chrome
from strong to weak: Titanium>nickelchrome>steel>gold.
is gold crown better than non precious alloy
no, it is too soft for working dogs
Is there such an alloy as cobalt-chrome-molybdenum for a working dog crown?
yes, these have been very successful, it is very hard alloy, corrosion resistant, hypoallergenic, non-irritating, and inexpensive
Alginate
an irreversible colloid used for study cases, preliminary impressions and orthodontic casts
What is the reproduction of detail, dimensional stability, tear strength, maximum time for pouring and comparative cost for: alginate?
Poor dimensional stability, and tear strength, reproduction detail, and immediate pour time, and low cost
What is the reproduction of detail, dimensional stability, tear strength, maximum time for pouring and comparative cost for:
hydrocolloid?
Fair reproduction, dimensional stability, low tear strength, intermediate pour time - 7 hours if wet, and low cost
What is the reproduction of detail, dimensional stability, tear strength, maximum time for pouring and comparative cost for:
Polyether
Excellent reproduction, very good dimensional stability, moderate tear strength, 7 days to pour if kept dry, and very high cost
What is the reproduction of detail, dimensional stability, tear strength, maximum time for pouring and comparative cost for:
vinyl polysiloxane
Excellent reproduction of detail, dimensional stability, high tear strength, 14 days to pour, high cost
Polysiloxane Impression Material
- High dimensional stability and low tear resistance
- The material has no taste or odor.
- Available in light-bodied, regular, and heavy-bodied forms
- Supplied in cartridges and in putty consistencies for single-impression or double-impression techniques
