Q

What are the oral issues with treating dental decay?

A

access
moisture control
dental anatomy
transient dentition
crown morphology
- narrow occlusal table
- broad IP surfaces
- thinner enamel and dentine layers
problems diagnosing caries
caries progresses more quickly to pulp

Q

How does a GIC work?

A

Acid base reaction between glass and poly acid

Q

What are the advantages of GIC?

A

Adhesive therefore conservative cavities
Aesthetic
Preventative (F-)
LC GIC
- improved handling and command set

Q

Why are the cavity designs conservative?

A

To optimise tooth integrity
Reduce load on restorative materials
Preserve pulp status
Reduce risk of further caries
(place retentive grooves with tiny round bur to supplement adhesion)

Q

How do compomers set?

A

Dual cured
Initial photopolymerisation
Followed by a conventional GIC set
- will not set in the dark
- absorb moisture from saliva
- handling easier than composite
