Clinical Aspects Of Adhesion Flashcards
Not from lecture (from Google for understanding )
What is a DBA?
Dentine bonding agent
What are the different types of DBAs?
Examples?
What is the link between caries and bonding?
What is very important to remember for adhesion?
Seal is the deal
Currently: remove all Caries Infected Dentine (CID) and some Caries Affected Dentine (CAD) put some can be left on cavity floor to protect the pulp . MINIMAL INTERVENTION AND PREVENTION WHERE POSSIBLE.
How much caries we remove is dependant on?
Minimally invasive rationale is dependant on?
What did this study show?
Findings part 2?
If sealant is intact, carious lesions do not progress
Analysis of bacteria surviving under dental restorations (nutrient stress)
Do we need to remove all of the decayed tissue?
Bacteria cannot survive happily under dental restorations (nutrient stress)
There is a huge reduction in total aerobic /anaerobic count
‘The seal is the deal’
Why is there limited Bacterial survival under dental restorations.
• Harsh, uniform, nutrient limited environment selected for specific genotypes and relevant phenotypes [simplification].
‘The seal is the deal’
Which part of caries do we remove ?
Layers of dentine?
Decision making for operative intervention
How much caries do we remove
What might future treatment look like
If we are going to restore a tooth with minimally invasive dentistry, what options for the restorative material do we have?
Structure of enamel
Enamel etching
Etching removes the smear layer and increases surface roughness
Adhesion of composites
Adhesion of composites
Lateral walls of proximal cavities
What is a problem with shrinking composites
Link between how you etch and shrinkage
How do we reduce risk of fracture are the interface
Lifetime perspective of bonding with resin
Historically was dentine easy to bond to
How do we categorise adhesives
Classification of DBAs
Type 1
How does it work?
Examples?
Gold standard
Classification of DBAs
Type 2
How does it work?
Examples?
