2mm
The isthmus width for a ceramic inlay is ______ minimum of intercuspal distance
1/3
(2mm)
The pulpal floor depth for a ceramic inlay is ______mm minimum
2mm
What is the divergence for a ceramic inlay?
6 degrees
What should you use to block out undercuts for a ceramic inlay?
GI
T/F: There should not be a bevel on any wall for a ceramic inlay
True
Eugenol bases and liners partially inhibit the _____________ of freshly mixed resin restorations and there is a __________ of the resin surface adjacent to the eugenol liner
polymerization; softening
(so make sure to use a non-eugenol cement!!)
What material has a rubbery consistency after it is fully cured?
Light cure composites
Should the glaze be extended to the intaglio of a restoration?
NO! Doing this will decrease bonding strength
A sign of acute apical inflammation
Vertical percussion
May also be caused by an occlusal interference or pulpitis (rare)
Vertical percussion
T/F: A negative test result for vertical percussion means there is no inflammation
FALSE, a negative result does not necessarily mean there isn’t any inflammation
Related to marginal and/or lateral periodontitis
Horizontal percussion
May also be caused by a vertical root fracture
Vertical and horizontal percussion
