Kinetics of Conversion of Two Dual-cured
Adhesive Systems
Abstract
The aim of this study was to evaluate the
kinetics of conversion of Scotchbond Multi-purpose Plus (3M ESPE, St Paul, MN)
and Prime&Bond NT (Dentsply De Trey, Konstanz, Germany) used in
light-cured, self-cured, or dual-cured versions. The adhesive systems were used
in the light-cured version (without the use of chemical initiator) or mixed
with its respective chemical initiator either with light activation
(dual-cured) or not (self-cured). The degree of conversion (DC) was monitored
as a function of time during 5 minutes with a Fourier transform infrared
spectrometer equipped with an attenuated total reflectance device. Light-cured
and dual-cured modes of Scotchbond Multi-purpose Plus presented the highest DC
at 5 minutes. The addition of the self-cure activator (dual-cured mode) to
Prime&Bond NT reduced the DC. For the self-cured versions, only the
Scotchbond Multi-purpose Plus presented any polymerization reaction at 5
minutes. For the two bonding systems tested, it appears that light curing of
the adhesive is important in order to reach a high DC in the first moments
after the bonding procedure.

Results and findings
- The kinetics of conversion of Scotchbond
Multi-purpose Plus (3M ESPE, St Paul, MN) and Prime&Bond NT (Dentsply De
Trey, Konstanz, Germany) as adhesive systems used in light-cured, self-cured,
or dual-cured version were investigated.
- The degree of conversion (DC) of the
adhesive systems was observed as a function of time during 5 minutes via a
Fourier transform infrared spectrometer.
- At 5 minutes, the DC of Scotchbond
Multi-purpose Plus in light-cured and dual-cured modes displayed highest value.
- In self-cured versions, only the DC of Scotchbond
Multi-purpose Plus showed the polymerization reaction at 5 minutes, while the
DC of Prime&Bond NT decreased.
- The dual-cured version is important for
bonding system because it can reach a high DC in the first moments after the
bonding procedure.

- Faria-e-Silva et al. (2008) reported that
the degree of conversion (DC) of Scotchbond Multi-purpose Plus in light-cured
and dual-cured modes displayed highest value at 5 minutes.
- According to Faria-e-Silva et al. (2008),
the dual-cured mode of an adhesive system can achieve a high degree of
conversion (DC) at the initial reaction after bonding process.

You are absolutely right! :D Thanks for pointing that out for your friend.
ลบThank you for your suggestion Krub :')
ลบGood start! One thing you should look at is articles.
ตอบลบ"displayed highest value at 5 minutes"
Whose highest value?
The "highest value" is the the degree of conversion (DC) of Scotchbond Multi-purpose Plus in light-cured and dual-cured modes. Krub
