To Fill or Not to Fill
The amount of radiographic D1 lesions that are actually clinically cavitated
40% (Pitts, 1992)
The amount of fluoride in varnish
22,600ppm
What is 8th generation bonding
The "Halo Effect" from conventional and RMGI protect this much of peripheral dentin with its fluoride release
2mm
The most common photoinitiator and its wavelength for curing
Camphorquinone; 468 Nm
The critical level of S. mutans for high risk disease in adults
What is 100,000 CFU/mL (Anderson, 1993)
The recommended Fluoride percentage in the drinking water in the USA
What in the tooth and blood would inhibit bonding?
Matrix metalloproteinases (MMPs) -- specifically MMP-2, MMP-9 (gelatinases) and MMP-8 (collagenase)
The four components of a glass ionomer
The three primary components of composite
Filler, coupling agent, matrix
The Seven Steps of the Anderson Medical Model
1. Caries control restorations
2. Sealants
3. Chlorhexidine and Fluoride varnish
4. Xylitol gum
5. Fluoride rinse and toothpaste
6. Recall and bacteriologic testing
7. Definitive restorations
This might be something you prescribe for xerostomia
Pilocarpine or Biotene
Improved formulation that is more radiopaque like dentin, bonds affected dentin as well as sound dentin, improved silane system, compatible with dual and self-cure materials, BPA free
Three phases of glass ionomer
1: ion leaching
2: hydrogel
3: poly-salt
The components in a resin matrix
Monomer (bis-GMA, UDMA, TEGDMA), initiator (camphorquinone, benzoyl peroxide), inhibitor (hydroquinone), pigments (titanium dioxide, aluminum oxide)
The critical pH of fluorapitite, enamel, and dentin
4.5, 5.5, 6.2, respectively
The way chlorhexidine gluconate mouthrinse works
Antimicrobial: the positive charge of CHX binds to cell walls of oral bacteria, damages the cell membrane killing the bacteria, and provides lasting action due to substantivity
The structure formed at the surface of dentin by prior demineralization followed by infiltration of monomers and their subsequent polymerization
What is the hybrid layer? (coined by Nakabayashi)
The rule of 200
Concentration x time = 200 for cavity conditioner
The acid, solvent, and infiltrant in ICON resin infiltration
Acid: 15% hydrochloric acid gel
Solvent (ICON-dry): 99% ethanol
Infiltrant: TEGDMA
The protective factors of the caries imbalance
What are "saliva & sealants, antibacterials, fluoride, and effective diet"
The goals of carious tissue removal (RAAMM)
1: Preserve remineralizable and healthy tissue
2: Achieve adequate seal
3: Avoid pain & anxiety
4: Maintain pulp health
5: Maximize restoration longevity
The three types of adhesive strategies in a bonding protocol
The three components in the "Tri-Cure" setting reaction of Resin Modified Glass Ionomer
Acid-base glass ionomer reaction (requires water) + light-cured resin reaction + self-cured resin reaction
150 MPa at baseline; decreases to 120 MPa at 30 months
