Class II lesions occur where? - ✔✔The proximal surfaces of posterior
teeth.... anything proximal on a posterior tooth
Where do class III lesions occur? - ✔✔Proximal surfaces of anterior
teeth NOT involving the incisal angle
Where do class IV lesions occur? - ✔✔Proximal surfaces of anterior
teeth when the incisal angle requires restoration
Class IV lesions are usually caused by? - ✔✔trauma
Where do class V lesions occur? - ✔✔in smooth, facial and lingual
surfaces in the gingival third of teeth on both anterior and posterior teeth
Factors that cause class V lesions? - ✔✔abrasion, acid erosion,
abfraction from grinding (chipping of enamel)
Where do class VI lesions occur? - ✔✔In the pit or wear defects on the
incisal edges of anterior teeth or the cusp tips of posterior teeth

What are the principles of cavity preparation? - ✔✔Outline, resistance,
retention, Convenience, removal of carious dentin, finish of enamel walls,
cleansing
What is meant by resistance form? - ✔✔resistance of tooth structure to
occlusal forces... you don't want to undermine dentin by undercutting or
gouging out, you want sound dentin supporting enamel
Resistance refers to? - ✔✔horizontal direction
Retention form refers to? - ✔✔vertical direction... not enough depth
could allow restorative to fracture or wear away
What is meant by convenience form? - ✔✔Convenience for the
operator... Must be able to have enough room to do the work you need to...
for 19 MO must open up buccal, lingual and gingival floor to pack
composite
Why must enamel walls be smooth? - ✔✔Jagged margins will allow
bacteria to accumulate
Poorly finished enamel walls will lead to what? - ✔✔recurrent decay
How do we cleanse teeth? - ✔✔consepsis before procedure...
afterwards we use air/water syringe to make things look nice (in sim clin)
