How do you differentiate 7th generation adhesives from Universal adhesives?
7th generation adhesives can only be used in self-etch mode and are more hydrophilic, while Universa
Are 1-layer adhesives good enough?
Traditional one-layer adhesives were permeable, which may have caused sensitivity, faster degradatio
Why do some universal adhesives require a separate self- or dual-cure activator?
Most Universal Adhesives contain an excessive amount of water and remain acidic, even after solvent
Can self-etch adhesives etch enamel?
Mildly acidic self-etch adhesives (pH > 2.0) do not effectively etch uncut enamel, and should be
Do I need to bond before placing TheraCal LC?
Bonding is not required or recommended before placement of TheraCal LC on dentin. The placement of a
Prior to bonding, should an antimicrobial agent be used on the dentin, and does that vary by different generations of bonding systems?
Yes, dentin should always be cleaned prior to bonding.If using an Total Etch (Etch-and-Rinse) adhesi
What is Immediate Dentin Sealing (IDS) and when should it be used?
IDS (Immediate Dentin Sealing) is when you seal the dentin with an adhesive at preparation for indir
How do I use the wet bonding technique with total-etch adhesives?
The best technique to leave the dentin moist is to either suction excess water with HVE or blot exce
Does my adhesive need to be radiopaque?
Radiopacity is only required if the film thickness of the adhesive layer is greater than 20-25 micro
How do I avoid sensitivity in my resin-based composites?
Post-operative sensitivity may be caused by incorrect bonding techniques, but has become less signif
The all-in-one adhesive that can be used for everything: does it exist?
Yes, the “universal” category of adhesives (not to be confused with 7th Generation “All-in-One” adhe
When should I use the total-etch and self-etch techniques?
In general, research has shown that the total-etch (etch-and-rinse) technique is ideal for enamel bo
What are MMPs and how do I inhibit them?
MMPs are Matrix Metalloproteinases, inactive enzymes in dentin that are activated by acid, and degra
Why can’t you use UNIVERSAL adhesives instead of a pure silane?
The reason that silane is not effective in universal adhesive systems is because Bis-GMA and other r
What are the advantages of using a self-etch adhesive?
The advantage of self-etching systems is that the smear layer is altered but never removed, resultin
What is Selective-etch?
Selective-etch is the placement of phosphoric acid on only enamel, indicated when using a self-etch
What are the limitations of using a self-etch adhesive?
One disadvantage of self-etch adhesives is that although the primer is acidic (pH just over 2.0); th
