Self-etch adhesives: Beyond the quest for low post-operative sensitivity
DENTAL ADHESIVES UPDATE
With the advent of self-etching
adhesives in the 1990s, dentists
now have an option for bonding
dentin and enamel without the
need for a separate etchant. This
innovation simplifies the bonding
procedure and reduces the
potential for patient sensitivity.
That reduction in sensitivity
has been the primary appeal of
these materials to date. Recently,
however, researchers have begun
to focus attention on the real
adhesion performance of these
materials on dentin and enamel
– particularly intact enamel.
Self-etch adhesives rely on
the use of phosphorylated
methacrylate monomers that
become acidic when combined
with water. These acidic
adhesives demineralize, or
"etch," tooth surfaces while
simultaneously penetrating
into the tooth, forming a strong
micromechanical bond.
On dentin, this simultaneous
etching and penetration, without
rinsing, helps reduce the potential
for sensitivity because dentinal
tubules are more likely to remain
sealed.
Virtually all self-etch systems
offer reduced sensitivity. Where
they differ is in their pH levels.
To provide an adequate etch,
particularly on uncut enamel,
an adhesive must maintain a
strong acidity. Without a low pH,
a self-etch system may lack the
ability to sufficiently etch and
penetrate enamel surfaces.
The lower the pH, the deeper
the etch. The pH of a typical
phosphoric acid etchant is about
0.7. Most self-etch adhesives
measure significantly higher.

Self-Etch Adhesive,
with its pH of 0.8, can provide
a deep etch pattern on enamel
surfaces, as indicated in the
SEM images.
Less acidic self-etch
adhesive systems cannot
provide as deep an etch
pattern. In fact, most of these
products actually require that
a separate phosphoric acid
etch be performed on uncut
enamel surfaces prior to
adhesive placement.
These products are often
specifically designed to be
less acidic to prolong shelf
life. Once phosphorylated
adhesive components are
combined with water, their
Single-bottle self-etch adhesives may seem convenient but research shows
that their higher pH makes them less effective on uncut enamel.
acidic characteristics are
activated. This causes the
methacrylate monomers to
become prone to hydrolytic
degradation, resulting in
decreased performance and
shorter shelf life.
Systems like Adper Prompt
adhesive avoid degradation by
delaying the mixing of water
and adhesive until just prior
to use. As a result, they can
be formulated at a lower pH.
Some manufacturers prefer
to combine water and adhesive
components to eliminate the
need for mixing. To prevent
hydrolysis, the adhesive is
formulated to a higher pH.
Even so, many still require
mandatory daily refrigeration
to reach the stated shelf life.

The lower pH of Adper Prompt adhesive provides a more pronounced etch than other self-etch
adhesives, allowing for use on UNCUT enamel without a separate acid-etch step.
The first wave of self-etch
adhesives were driven by the
desire to reduce patient
sensitivity. Now, the bigger
challenge is to find a self-etch
adhesive that can also form
a strong bond consistently
to uncut enamel, prepared
enamel and dentin surfaces,
but maintains the benefits of
a longer shelf-life.
For the time being, only
self-etch adhesives that
maintain a low pH, like Adper
Prompt Self-Etch Adhesive,
can offer strong bond
performance on intact enamel
surfaces without a separate
etch step. That makes them
the best choice for true
convenience and versatility.

Newer single-bottle self-etch
products and the acidic-based
primers of two-component
systems fall into this second
category. As a result, they are
less effective on uncut enamel
surfaces and generally require
a separate phosphoric acid
treatment on enamel prior to
placement of the adhesive.
