1

Name the steps of naming the angles of teeth

1. Start with position i.e. mesial or distal
2. Then labial/buccal or lingual/palatal
3. Then incised or occlusal

e.g. distolabioincisal or disto-bucco-occlusal

2

What are the roots of the tooth made of

dentin and cementum

3

Is pulp bigger in permanent or deciduous teeth

bigger in deciduous

4

What is the marginal ridge of the tooth

The strip of enamel on the lingual side of the anterior teeth that form a V shape
On posterior teeth its the mesial and distal strips of enamel on the occlusal surface

5

Point out the cervical, middle and apical regions of the crown and root of a tooth

Cervical = top of root, bottom of crown
Middle = middle
Apical = top of crown, bottom of root

6

What is a cusp tip

major elevations on the masticatory surface of posterior teeth and canines

7

Name the 4 cusp tips found posterior teeth

Distolingual
Mesiolingual
Distobuccal
Mesiobuccal

8

What is a ridge on a tooth

Linear elevation on a tooth crown

9

What is the transverse ridge

Linear elevation crossing occlusal surface of any molar
Buccal --> Palatal

10

What is the oblique ridge

Linear elevation diagonally crossing occlusal surface or maxillary molar
More developed than transverse, with lesions for strength

11

Just a likkle note

teeth with one root can have 2 canals

12

Why is one of the cusps on the 2nd maxillary molar higher than normal

It is further from where it needs to reach than other cusps
