Caries and Cavity Prep Terminology

Question 1

dental caries

Answer 1

an infectious microbiological disease of the teeth that results in localized dissolution and destruction of the calcified tissues

Question 2

Only use “cavity” when?

Answer 2

speaking with patients

Question 3

what is both plural and singular?

Answer 3

caries

Question 4

what five things describe caries?

Answer 4

sequences, location, extent, rate, activity

Question 5

‘sequence’ for caries description?

Answer 5

• Primary (Initial) Caries = restoration absent

* Secondary (Recurrent) Caries = restorations present

Question 6

‘location’ for caries description?

Answer 6

• Pit and Fissure Caries (includes occlusal, buccal, lingual and cingulum grooves)
• Smooth Surface Caries
• Root (cemental) Caries

Question 7

Extent of Dental Caries: Incipient vs Advances

Answer 7

• Incipient Caries
• –enamel only
• –no cavitation
• Advanced
• –DEJ involved
• –cavitation present- developing hole and losing tooth structure

Question 8

‘Dental Caries Rate’ for caries description?

Answer 8

• Acute (rampant) Caries

- Chronic Caries

Question 9

Dental Caries Activity: Active vs Arrested

Answer 9

• Active
• –continued demineralization
• Arrested
• –stabilized decay state

Question 10

How many Classification of Dental Cavies/Preparations are there? Who made them?

Answer 10

6; GV Black made the first 5

Question 11

Class I

Answer 11

• Pit and Fissures
• –occlusal, buccal and lingual surfaces
• *Occlusal Surfaces of the Molars and Premolars

Question 12

Class II

Answer 12

• Proximal Surfaces of the Molars and Premolars

- –mesial and distal

Question 13

Class III

Answer 13

*Proximal Surfaces of the Incisors and Canines

Question 14

Class IV

Answer 14

*Proximal and Incisal Surfaces of the Incisors and Canines

Question 15

Class V

Answer 15

*Cervical (gingival) surface of the Anterior or Posterior Teeth

Question 16

Class VI

Answer 16

• Incisal Edges
• –anterior teeth
• Occlusal Cusp Tips
• –posterior teeth

Question 17

Simple vs compound vs complex

Answer 17

Simple: one surface
Compound: two surfaces
Complex: 3 or more surfaces

Question 18

“Box Form”

Answer 18

• Walls
• Line Angles
• Point Angles
• Cavosurfaces

Question 19

Walls

Answer 19

• Enclosing Surfaces

- Named from the Adjacent Tooth Surfaces or Direction

Question 20

Walls vs Floors

Answer 20

• Walls are along the long axis of a tooth

- Floors are generally 90 degrees to the long axis

Question 21

Pulpal floor faces?

Answer 21

the pulp; 90 degrees to the long axis of the tooth

Question 22

Axial wall face?

Answer 22

the pulp

Question 23

Line Angles

Answer 23

• Formed at the Junction of Two Walls

- Named by Combining the Names of the Joining Walls

Question 24

Point Angles

Answer 24

• Angle or “Corner” formed by the Junction of Three Walls

- Named by Combining the Names of the Joining Walls

Question 25

Cavosurface Angles

Answer 25

-Line or Angle formed at the Junction of a Cavity Preparation Wall and the Unprepared Surface of the Tooth -“Cavosurface Margin”

Question 26

restoration vs filling

Answer 26

restoration is what dentists do... fillings are in pie

Question 27

Class V Retention Grooves

Answer 27

* Dentin ased * Located at the Junction of the Axial and Occ/Gin Walls * Not at the DEJ * ¼ round bur * Approximately 0.5mm deep

Question 28

tell-tail sign of chronic or rampant decay?

Answer 28

pulp horn will shrink as a protective measure if the decay has been happening for awhile

Question 29

what two restorations take the most stress?

Answer 29

4 and 6

Question 30

purpose of retention grooves? what side of preparation is best?

Answer 30

to make 'undercuts' that lock restorations in place; Occlusal and gingival retention grooves (M & D not as good)

Question 31

why do you round line angles?

Answer 31

to prevent fracture

Question 32

Caries that do NOT penetrate the DEJ are called?

Answer 32

incipient caries

Question 33

T/F... a line angle is the junction of 3 walls?

Answer 33

false (a point angle is 3 walls)
