Chapter 8: Clinical Technique for Direct Composite Resin and Glass Ionomer Restorations (page 220 - 224)

Composite is composed of filler particles + matrix. Resin is the material that forms the --- in composite

matrix

When a tooth is significantly weakened by extensive defects, however esthetics is of concern, what is used?

A ceramic onlay or crown

Should composite be used if an operating site cannot be isolated from contamination by oral fluids

No - composite should not be used. Can use RMGI

Should composite be used if an operating site undergoes heavy occlusal forces

No - composite should not be used. Should use amalgam

What are the advantages of composite restorations?

Esthetics

Conservative tooth prep

Universal use

Low thermal conductivity

Bonds to enamel

What are the disadvantages of composite restorations?

Polymerization shrinkage

Marginal deterioration / microleakage

More difficult / time consuming to place

Which materials are more technique sensitive: amalgam or composite

composite

When are sealants most effective in children?

When applied to pits/fissures immediately after permanent teeth erupt

What is the treatment for a non-cavitated caries

No treatment

Fluoride

38% SDF

Sealant

True / False: sealants should be used primarily for the treatment of existing caries lesion rather than for prevention of caries

False - should be used for the prevention of caries primarily

True / False: if proper isolation cannot be obtained, the bond of a sealant material will be comprised

true

Properly acid-etched enamel surface has a --- appearance

chalky/frosted

Conservative composite restoration

minimal remold of tooth structure combined with use of flowable composite or sealant

If a definitive diagnosis of caries cannot be made for the entire occlusal surface, a ---- of the suspicious area is performed with a small bur or diamond to determine the extent of the suspected fault without extending onto noncompromised fissures

conservative preparation

When is the conservative preparation used most?

In patients with high caries risk

What happens if an occlusal conservative preparation reveals extensive decay?

The preparation is extended until decay is removed / sound tooth structure is revealed

Conservative preparation can change to a classic preparation

Preparation is restored with composite

What is needed for restoring the occlusal surface of a posterior tooth?

Diagnosis

When is a conservative preparation used?

When a definitive diagnosis can not be may but their is a suspicious area - drill into suspicious area without extending into non-comprised areas
