Restorative Materials For The Primary Dentition Flashcards
Why restore primary teeth?
To prevent pain
To repair or limit the damage of dental caries
To protect and preserve the pulp and remaining tooth structure
To ensure adequate function
To restore aesthetics
To provide ease in maintaining good OH
To maintain space
What general factors must we consider when choosing a restorative material?
Age of patient-how long must tooth last Co-operation Medical history Caries rate/risk Parental preference Anaesthesia used
What dental factors must be consider when choosing a restorative material?
Extent of lesion
OH
What different restorative material options are there?
Composite
Compomer
GI
SS crowns
What are the advantages of composite?
Adhesive
Aesthetic
Reasonable wear properties
Command set
What are the disadvantages of composite?
Technique sensitive
Ideally rubber dam used
Expensive
Shrinkage
When do we use composite?
Occlusal restorations
Small interproximal restorations
Anterior restorations
What is compomer?
Composite and GI
What are the advantages of conventional GI?
Adhesive
Tooth coloured
Fluoride leaching
Good for stabilisation of multiple carious teeth
What are the disadvantages of conventional GI?
Brittle
Susceptible to erosion and wear
What are the advantages of RMGI?
Adhesive Aesthetic Command set Easy to handle Fluoride release
What are the disadvantages of RMGI?
Water absorption
Wear
When do you use RMGI?
Temporary restorations
In patients who have high caries rate (fluoride reservoir)
When do you use high viscosity GI?
Atraumatic restorative technique
What are the advantages of performed metal crowns?
Durable
Protect and support remaining tooth structure
Hall technique option
What are the disadvantages of performed metal crowns?
Conventional prep- extensive tooth preparation
Patient cooperation required
Unaesthetic
When do you use performed metal crowns?
If there is caries present in over 2 surfaces Following pulpotomy or pulpectomy Fractured teeth Tooth surface loss High caries rate Poor OH
What is % chance of survival of preformed metal crowns after 5 years?
68%
What is the % chance of survival of amalgam after 5 years?
60%
What is the % chance of survival of composite after 5 years?
40%
What is the % chance of survival of GIC after 5 years?
5%
