Sometimes referred to as a floor instead
It takes the name of the surface of the tooth toward which it is placed
wall
The wall adjacent to or nearest to the pulp chamber
It is in a line parallel to the long axis of the tooth
Axial Wall
The floor of the prep which covers the pulp
Located at right angles to the long axis of the tooth
It is also known as a “wall”
Pulpal Wall or Floor
The wall of the cavity prep which is laid toward the distal surface
The wall of the cavity which is laid toward the mesial surface
Distal and Mesial Wall

Cavopsurface Margin
A gap between the restorative material and cavosurface margin
Detection: the tip of the explorer catches when moving from restorative material to tooth structure
Void, Deficiency and open margin
A small gap between the restorative material and tooth structure
Not able to be measured
May be felt with the explorer!
Less than 0.5mm
Deficiency
A large, measurable gap between the restorative material and tooth structure Measured with the tip of a probe Greater than or equal to 0.5mm Width Length Depth
Void
A distinct, visible void between the restorative material and the cavosurface margin
Larger than 1mm
Open Margin
Causes of Open Margins
Incorrect manipulation of material Triturating Condensing Burnishing Interference of other materials Bases Rubber Dam Wedge Caries
