Flashcards in Carnivore dental Deck (56):
1

What is the normal periodontal depth in a cat?

0-1mm

2

What is the normal depth of the periodontal pocket in a dog?

0-3mm

3

What may a greater periodontal depth than normal be indicative of?

Disease in the periodontal space, e.g. periodontitis

4

What does R stand for when completing a dental chart?

Restoration

5

How is enamel defect coded for by a dental chart?

ED

6

What does RT stand for on a dental chart?

Retained temporary tooth

7

What does CA stand for only a dental chart?

Carious lesion

8

What 4 factors are examined and graded when performing a dental examination?

Gingivitis
Plaque
Calculus
Periodontal pocket

9

Why are some dog breeds more prone to dental disease than others?

Retained deciduous teeth into adulthood

10

What kind of teeth do dogs and cats have: hypsodont or brachydont?

Brachydont

11

At what age do deciduous teeth begin erupting in both species?

Approximately 5wks

12

Which teeth are not present in the deciduous dental formula of both species?

Molars

13

At what age do permanent teeth begin erupting?

By 7mo

14

Which of the premolars in both species possesses only a single root?

1st maxillary premolar

15

How does the first maxillary premolar differ from the others in both species?

This is the only tooth of the premolars to have a single root, compared with the 2 diverging roots of the other premolars

16

Which teeth in dogs are single rooted unusually?

1st maxillary premolar
1st mandibular premolar

17

How many deciduous teeth does a kitten have?

26 deciduous teeth

18

What is the deciduous dental formula for kittens?

2(I 3/3 C 1/1 P 3/2) = 26 teeth

19

When do the deciduous teeth in a kitten erupt and finish emerging?

Deciduous teeth begin emerging at 4wks and have come through by 8wks

20

At what age do the cats' permanent dentition begin emerging?

Incisors at 3-4mo

21

Which species has a degree of grinding surface to their occluding aspect of their molars? Why

Dogs have a grinding surface to their molars as their diet is not as specialised as cats

22

What is the role of the periodontal ligament?

Shock absorption
Permits tiny movements of teeth during mastication

23

Which species has the smaller periodontal pocket?

Cats

24

What is the root covered by?

Cementum

25

What material covers the crown of teeth?

Enamel

26

Where is the periodontal ligament found?

Between the tooth and its alveolar socket

27

What layer is the pulp cavity deeper than?

Dentine

28

What feature of teeth makes them difficult to extract?

Many teeth roots have a bulbosity at the end which can complicate extractions

29

What are the alveolar sockets lined by?

A cribriform plate

30

How is the cribriform plate identified radiographically?

As the lamina dura

31

What does disruption of the lamina dura indicate?

Dental disease

32

Which teeth in a dog have 2 roots?

Maxilla: 06 07 10
Mandible: 06, 07 08 09 10

33

Which teeth have 2 roots in a cat?

Maxilla: 07
Mandible: 07 08 09

34

What do maxillary teeth 08 and 09 have in common in a dog?

They both have 3 roots

35

Which teeth in a cat have 3 roots?

08 maxillary teeth

36

Why are cats teeth more complicated to extract?

Their periodontal space is considerably smaller
Their roots are smaller

37

Which teeth are single-rooted?

Incisors
Canines

38

What is the name of the numbering system employed for the dental arcades?

Triadan numbering system

39

How many teeth are there on each arcade in a dog?

10 on each upper arcade
11 on each lower arcade

40

What is the danger posed to cats by inflated endotracheal tubes?

Cats have highly sensitive larynxes that can go into spasm with an inflated tube

41

In which species is an ET tube fitted and the cuff inflated?

Dogs - due to sensitive nature of cats' larynxes

42

What should be inserted into the pharynx and regularly changed to prevent blood or debris from entering the trachea?

Pharyngeal pack

43

What vital sign should be monitored in particularly when dental procedures or exams are being performed?

Body temperature as this can rapidly fall during dentals

44

What is the difference between calculus and plaque?

Calculus is mineralised plaque
Plaque is a sticky, light colour biofilm that initially contains gram + aerobes

45

What is periodontal disease commonly caused by?

Subgingival plaque and calculus

46

What components are graded in a canine dental chart?

Gingivitis
Plaque
Calculus

47

What additional section is present on a feline dental chart?

Resorptive lesions

48

Why is adequate water spray crucial when using a scaler?

To prevent heating and damaging of teeth

49

How is damage to the enamel prevented when using a dental scaler?

Scaler must be kept moving at all times
Flat of tip must be used for each tooth

50

What is the aim of scaling?

To remove calculus present above and below gumline, hence leaving behind a smooth surface to inhibit future buildup

51

If there is a periodontal pocket >2mm depth, what piece of equipment should be used?

A hand curette

52

How many places should the periodontal pocket be assessed?

6 places (3 buccal, 3 lingual)

53

What is used to perform polishing of teeth?

Fine grade prophy paste
Prophy cup

54

How long should be spent scaling each tooth?

No more than 2s

55

What is the maximum period of time that should be spent polishing a tooth?

2s

56

What is the difference between canine and feline dental charts?

Cats teeth are numbered as if they are dogs with missing teeth, hence explaining the gaps in feline dental charts
