Tensile bond strength
The tensile bond strength of 8 state of the art bonding systems to bovine enamel and
dentine was measured in house according to the following protocol.
1) The labial surfaces of extracted bovine anterior teeth are polished with SiC (silicon
carbide) paper (#600). The polished surface is used for the measurement of
tensile bond strength.
2) The bonding test area (4.91 cm 2 ) is marked with plastic tape (2.5 mm in
diameter).
3) The self-etching primer is dispensed onto the polished tooth surface, and left
undisturbed for 20 seconds.
4) The surface is dried with gentle air blowing for 5 seconds.
5) The bonding agent is applied to the primed enamel or dentine surfaces and light
cured for 10 seconds.
6) Composite resin is placed onto the cured bond, and light cured.
NB. For competitive bonding systems, the respective instructions of the
manufacturer were used. Step 3 to 6 applies for GC UniFil Bond.
Within the limitations of this
test it can be concluded that:
1) Compared to Prompt L-Pop,
Prime&Bond NT, XENO III and
AdheSE, the bond strength to
enamel of UniFil Bond is higher.
2) Compared to Clearfil SE
Bond, Single Bond and Syntac
classic, the bond strength to
enamel of UniFil Bond is similar.
3) Compared to Prompt L-Pop,
Single Bond, Prime&Bond NT,
XENO III, AdheSE and Syntac
classic, the bond strength to dentin of UniFil Bond is higher.
4) Compared to SE Bond, the bond strength to dentin of UniFil Bond is similar.
