Mesial : Toward the midline of the dental arch

Distal: Away from midline (caudal)

Proximal: (contact) surface facing adjoining teeth

2

What is a wider space between teeth called?

Diastema 

3

Occlusal

4

_______ means toward the root or away from the crown. _______ means toward the crown.

5

What is a Chevron Sign?

Widened periodontal ligament spaces in the apical areas of endodontically sound (healthy) teeth

6

What is the lamina lucida? What is the lamina dura?

Periodontal ligament 

Cortical bone

7

What absorbs shock, supplies nutrients to alveolar bone and cementum as well as providing tactile and proprioceptive info?

Periodontal ligament 

8

What can excessive vitamine D in cat food cayse?

Ossification of the periodontal ligament

9

What is the anatomical system for numbering teeth? What is the Triadan system?

Anatomic: Teeth labled based on type of tooth (M=molar, I=incision, C=canine) plus a number to the right or left of the letter as a sub or superscript (side of mouth, mandible vs maxilla)

Triadan: each tooth assigned 3-digit number; right maxilla = quadrant 1 = number start with 1, etc. (for deciduous 5, 6, 7, 8 instead of 1, 2,3,4)

10

What is the dental formula for a dog? Cat?

Dog: 3/3, 1/1, 4/4, 2/3 x2 =42 total

Deciduous: 3/3, 1/1, 3/3 x2= 28 total

 

Cat: 3/3, 1/1, 3/2, 1/1 x2= 30 total

Deciduous: 3/3, 1/1, 3/2 x2=26 total

11

Which teeth are considered carnassial in carnivores? What does this mean?

PM 4 on maxilla

M1 on mandible

Largest teeth in the mouth, essential for shearing flesh

12

What layer of the tooth is the largest?

Dentin 

13

Where do the nerves and vessels enter the pulp cavity?

Apical delta

14

What is this? What does it overlie?

Incisive papilla

Vomeronasal organ

15

What does pulp consist of?

Blood vessels

Lymphatics

Nerves

Connective tissue

16

3

1

17

What is the rule of 4 and 9?

The 4th tooth is always the canine tooth

The 9th tooth is alwats the first molar 

18

In relation to the deciduous tooth, where do the adult teeth erupt?

Lingual/Palatal

Except maxillary canines which erupt mesial

19

Upper PM1

21

_______ is the joining of two teeth, typically there will be ____ crown(s) and _____ root(s). 

_______ is the incomplete splitting of two teeth, typically there will be ____ crown(s) and _____ root(s). 

Fusion: 1 crown,  2 roots

Gemination/twinning= 2 crowns, 1 root

True

Class 2: Mandibular brachygnathism, mandible too short or maxilla too long

Class 3: Mandibular prognathism, mandible too long or maxilla too short

26

What is the difference between attrition and abrasion?

Attrition = wearing away of crown by tooth against tooth contact
