1
Q

Pit and fissure caries

A

pits and fissures on the occlusal surfaces of posterior teeth, buccal surfaces of posterior teeth, buccal and lingual surfaces of molars, lingual surfaces of maxillary anterior teeth

2
Q

smooth surface caries

A

on the surfaces that are pit and fissure free

3
Q

root surface caries

A

more in the elderly, follows an advanced gingival recession

4
Q

active caries

A

rampant or chronic

5
Q

chronic caries

A

slow, long standing. Dark in color and there is a good chance of remineralization in early stages to reverse the process

6
Q

rampant caries

A

rapidly invading, softer lesions. Often due to a cause such as meth mouth, radiation or nursing bottles

7
Q

arrested caries

A
  • not showing any further progression

- smooth and polished-like surface

8
Q

recurent/ secondary caries

A

caries under a preexisting faulty restoration

9
Q

Class I Caries

A

Pits and fissures of the occlusal surfaces of premolars and molars; buccal or lingual pits/fissures of the molars; lingual pit near the cingulum of the maxillary incisors

10
Q

Class II Caries

A

Involving the proximal surfaces (medial and distal) of premolars and molars

11
Q

Class III Caries

A

Proximal surfaces of incisors and canines

12
Q

Class IV Caries

A

proximal surfaces of incisors and canines, but will involve the incised edge

13
Q

Class V Caries

A

gingival third of the facial or lingual surface of any tooth

14
Q

Class VI caries

A

involve the incised edges of anterior teeth and the cusp tip of posterior teeth

15
Q

fundamental concepts for all tooth preparations

A
  • removal of dental caries
  • removal of weak tooth structure to provide well-supported sound hard tissue
  • pulp protection
16
Q

isthmus

A
  • In a class I preparation, it is the narrowest portion of a cavity prep
  • In a class II preparation, it is a portion of the cavity connecting an occlusal portion and a proximal portion together
17
Q

dovetail

A
  • In class I cavity preparation, isthmus connects the 2 dovetails
  • The dovetail design includes each marginal fossa and the developmental grooves around the marginal pits
18
Q

cavosurface margin

A

the junction between the external walls of the cavity prep and the uncut tooth surface

19
Q

Basic Cavity Preparation

A
  1. outline form
  2. Resistance form
  3. Retention form
  4. Convenience form
  5. Finishing
  6. Debridement
