What’s the difference between Primary vs. Secondary caries?
Terms to describe size of a filling:
What wall surfaces on a tooth is considered when we do fillings?
What angles on a tooth is considered when we do fillings?
What type of angle + margin is used as reference when doing fillings
List the principles of tooth preparation we need to consider when doing fillings:
List the 9 steps of tooth preparation :
In general what is the correct alignment of rotary instruments when we are dealing with caries on the
a) occlusal/proximal surfaces
b)facial/ oral surfaces
Define the principle of Resistance form:
prevention of fracture of restoration or tooth structure under occlusal forces.
Factors affecting resistance form:
* depth of the cavity
* thickness of remaining cavity walls
* internal angles
* pulpal wall (floor)
* cavosurface angle
Define the principle of Retention form + give 2 types ‘locks’ that we can place on a filling to ensure it doesn’t fall out.
Define the principle of Convenience
Define the principle of Caries removal
Define the principle of External wall finishing
Define the principle of Cavity debridement
