Term
- obtain outline form
- obtain resistance form
- obtain retention form
- obtain convenience form
- remove remaining carious dentin
- finish enamel walls and cavosurface margins
- clean the preparation
|
|
Definition
| black steps of cavity preparations |
|
|
Term
outline form
final outline form is not established until all carious and overlying enamel is removed |
|
Definition
based upon location and extent of carious lesion, tooth fracture, or erosion
- established after penetration in carious dentin and removal of enamel overlying carious dentin
- determinant is extent of carious dentin |
