Prevention of periodontal disease involves all of the following except:
daily teeth brushing, regular exercise, routine professional scaling, proper diet - regular exercise
- In normal occlusion, the bite is termed:
- scissor bite
- the upper 4th premolar communicates with which sinus?
- Maxillary sinus
-
To prevent the pulp tissue from thermal damage during ultrasonic scaling, which of the following should be done?
use constant irrigation, change tips frequently, use slow rotational speed, use approperiate amounts of paste -
use constant irrigation;
this helps prevent temperatures from rising too high - A complication that may develop if subgingival plaque is improperly removed is:
-
torn epithelial attachment;
excessive force may degrade epithelial attachment - What drug should not be given to pregnant dogs because it may cause discoloration of the puppies' teeth?
- Tetracycline
- An elongation of one side of the animal's head results in:
- Wry mouth
- What answer identifies the directional term for toward the root?
- Apical
-
Mrs. Walker comes to pick up her dog after dental prophylaxis has been performed. Which of the following topics would not need to be discussed as a part of the discharge instructions?
chewing exercises, home care, how to give injections, dietary con - how to give injections
- What instrument is used for root planing?
- Curet
- When one or more of the upper incisors rest caudal to the lower incisors and the rest of the occlusion is normal, what is it called?
- anterior crossbite
- Generally speaking, most dental instruments should be held as you would a:
- pencil
- The depth of a normal gingival sulcus is:
- 1-3mm
- What is the directional term for toward the front of the head?
- rostral
- What is the hard mineralized substance on the tooth surface called?
- calculus
- If the lower incisors seem to be excessively loose in a crachycephalic of minature-breed dog, what should you do and why?
- test the depth of the gingival sulcus becuase in many of these types of dogs, the incisor teeth may not be in individual bony sockets, but suspended in connective tissue which allows them to be mobile.
- The normal adult canine mouth has how many permanent teeth?
- 42
- What is the instrument used for removal of supragingival calculus?
- scaler
- What is the correct dental formula for an adult dog?
- 2(I3/3 C1/1 P4/4 M2/3)=42
- What is the proper dilution of chlorhexidine solution for use in the mouth?
- 0.2%
- After polishing with a prophylactic paste containing fluoride, a rinse with diluted chlorhexadine:
- is less effective because the fluoride interferes with bonding of chlorahexadine to tissues
- What does the term polydontia refer to?
- supernumary teeth
- The first dental examination should occur when:
- the animal is 6-8 weeks old
- When performing dental prophylaxis, you should be sure to wear:
- Mask, eye protection, gloves
- Ideally, the cutting edge of the scaler should be held at what angle to the tooth surface?
- 45-90 degrees
- As a dentifrice for use in small animals, baking soda:
-
should not be used as a dentifrice for animals;
it contains large amounts of sodium that can be absorbed into the pet's system. - Nerves and blood vessels enter the tooth through the:
- apical delta
- What is the space between the roots of the same tooth?
- furcation
- What is the minumum age for a cat to have all of its permanent teeth?
- 6mo
- The most common dental procedure performed on horses is:
- floating: the process of filing sharp edges off cheek teeth
- What is the word that identifies the tooth surface facing the cheeks or lips?
- buccal
- The root lenth of an upper canine is hoe ling compared with the length of the exposed portion of that tooth?
- 1 1/2 times the length
- The crown of a tooth is defined as:
- The portion above the gum line and covered by enamel
- What does topical fluoride do?
- helps to desensitize teeth and slows the rate of plaque formation
-
Which tissue is not part of the periodontium?
peridontal ligament, alveolar bone, root, gingiva - root
- What is the bulk of a tooth composed of?
- dentin
- What should one do when a patient has fractured deciduous teeth?
- extract them
- The thin film covering a tooth that comprises bacteria, saliva, and food particles is called:
- plaque
- What is the most common mistake made in treating periodontal disease?
- Inadequate root planing
- What is the insturment used to detect subgingival calculus?
- Explorer
- What is the range for acceptable gingival sulcal measurements in cats?
- 0.5-1mm
- What is the instrument used to measure pocket depth?
- periodontal probe
- What is the word that identifies the loss of tooth structure by chemical means?
- erosion
- Where do you use a curet?
- it can be used either supragingivally or subgingivally
- What is a wearing away of teeth by tooth-against-tooth contact during mastication?
- attrition
- What is the correct dental formula for an adult cat?
- 2(I3/3 C1/1 P3/2 M1/1)=30
- Tell me about the roots of the deciduous incisors.
- They have roots that are proportionately longer than the roots of permanent incisors
- Chlorahexadine contributes to dental prophylaxis by:
- bonding to the cell membrane and inhibiting bacterial growth for up to 24 horus
- What is the instrument used to measure the depth of the gingival sulcus?
- peridontal probe
- Removal of calculus and necrotic cementum from the tooth root is called:
- root planing
- In which grade of periodontal disease does early pocket formation occur without initial bone loss?
-
Grade III;
however, early bone loss in the late stage of grade III can be verified by radiographic examination -
Which tooth has 3 roots?
upper canine, lower 1st premolar, lower 1st molar, upper 4th premolar -
upper 4th premolar;
the other listed have 1 or 2 roots - The occlusal surface of a caudal tooth is defined as the:
- chewing surface of the tooth
- Once plaque has formed on a bone, how long does it take to mineralize into calculus?
- about 7 days
- What is the purpose of fluoride treatment?
- strengthen enamel and help desensitize teeth
- Of cats and dogs aged 6 years and older, approximately what percentage have periodontal disease?
- 85%
