Q

What technique is used to improve adhesion of composite resin restorative to tooth?

A
  • 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

16
Q

over-etching

A
  • destroys integrety of the dentinal tubules

- weakens bond strength

17
Q

purpose of bonding agent in tooth restoration

A

-create link between enamel and dentin (hydrophilic) and the dental adhesive resins which are hydrophobic

18
Q

What is a float?

A

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

19
Q

If cat has regurgitant systolic murmur, heard best over sternum and a gallop rhythym, what type of preanesthetic work up should you do?

A
  1. CBC, chem, UA,

2. cardiac work up with EKG, Echocardiogram, BP and thoracic rads

20
Q

What heart condition can this cat possibly have?

A

Mitral regurg,

cardiomyopathy, and congenital heart defect and endocarditis

21
Q

gingivectomy

A

excisional procedure to remove soft tissue wall of periodontal pocket

22
Q

Methods of gingivectomy

A
  • gingivectomy knives
  • cold steel surgical blade
  • electrosurgery
  • laser
  • round bur
23
Q

How fast does epithelial migration over gingival wound occur?

A

one day for every 0.5 -1 mm covered

24
Q

when is a gingivectomy recommended

A
  • pseudopockets

- gingival hyperplasia

25
Q

When is it contraindicated to do a gingivectomy?

A
  • infrabony defects where incomplete pocket removal and reverse architecture would result
  • narrow band of attached gingiva

-bone overgrowth is the problem

26
Q

What is the membranous bulge lingual to the 1st mandibular molar on a cat mouth?

A

Molar or lingual salivary gland

27
Q

order from hardness to softest
-porcelain

enamel

gold alloy

non-precious alloy

amalgam

dentin

A

porcelain>non-precious alloy> enamel> amalgam> gold alloy. dentin

28
Q

What is order of weakness of gold, steel, titanium, nickel chrome

A

from strong to weak: Titanium>nickelchrome>steel>gold.

29
Q

is gold crown better than non precious alloy

A

no, it is too soft for working dogs

30
Q

Is there such an alloy as cobalt-chrome-molybdenum for a working dog crown?

A

yes, these have been very successful, it is very hard alloy, corrosion resistant, hypoallergenic, non-irritating, and inexpensive

31
Q

Alginate

A

an irreversible colloid used for study cases, preliminary impressions and orthodontic casts

32
