Restorations in primary and mixed dentition Flashcards
Aims of restoration of carious primary teeth?
Eradicate disease and restore health Prevent pain Avoid infection Preserve space Simplest treatment for child Comfortable/efficient mastication
What materials are generally used in CDH?
GIC
Composites
Pre-formed metal crowns
Why should you try and conserve primary molars?
Keep teeth in position until permanent molars are ready to erupt
What patient factors influence cavity design and choice of material?
Age - is the tooth ready to exfoliate, how long will it need to last, can they cope with LA
Caries risk
Co-operation
Aesthetic
What tooth factors influence cavity design and choice of material?
How close to exfoliation
Extent of caries
Cavity shape once caries removed
Management of anterior lesions?
Composite/compomer
Maybe inter proximal stripping? - remove contact points
Materials considered to anterior teeth?
GIC
Composite
Compomers
Management of posterior cavity?
Pre-formed metal crowns
GIC
Compomer
Composite
Advantages of GIC?
Adhesive
Aesthetic
Fluoride leaching
Disadvantages of GIC?
Long setting time Brittle Susceptible to erosion and wear Radiolucent Risk of further caries
What material is used to fissure sealant?
GIC
Advantages of compomer?
Adhesive Aesthetic Command set Simple to handle Radioopqaue
Advantages of composites?
Adhesive
Aesthetic
Comparable wear properties to amalgam
Command set
Disadvantages of composites?
technique sensitive Need to use rubber dam - LA Diagnosing secondary caries is a problem Expensive Need good co-operation and low caries rate
What is the gold standard for paediatric restoration?
Pre-formed metal crown
