The exam will be on Class I,II,III,IV and V amalgam preparations, Class III, IV and V composite preparations and liners & bases. It's pretty much a test to see if we understand the theory behind all the work we've been doing in the Sim lab: retention form, resistance form, convenience form, convergence, divergence, pulpal floor depth, cavosurface line angles, axio-pulpal line angles, etc.
Here are examples of what I'm talking about:
|Class I (OL)|
Involves Pits and fissures of posterior teeth, like the one pictured.
Also involves lingual pits of maxillary anterior teeth and Occlusal 2/3rd ( Buccal/Lingual) of Posterior teeth.
|Class II (MO)|
Involves Proximal surfaces of Posterior teeth
Involves proximal surfaces of incisors and cuspids, does not involve the incisal edge
Like Class III but it involves the Incisal edge. Look closely, u can
see where the restoration differs from the actual tooth
Involves the gingival third (Facial /Lingual) of all teeth.
...and that's all I have time for. Wish me luck!
