G-ænial Bond Technical Manual

7.2 Bonding performance on dentine

G-ænial Bond is designed for use of the self-etch approach on dentine, meaning that no phosphoric
acid etching agent is used prior to application of the adhesive. the bond strength to dentine is
optimal in the self-etch mode. in order to confirm the bonding performance of the adhesive layer
observed on the Sem and tem images, shear bond strength (SBS) and microtensile bond strength
(µtBS) tests were conducted internally and externally. Furthermore, although etching of dentine is
not recommended with G-ænial Bond, some inadvertent etching could occur while selectively
etching the enamel. therefore, the influence of etching on dentine was also analysed, both
quantitatively and qualitatively.

7.2.1 Shear bond strength to dentine using the self-etch technique

Tests performed by GC R&D, Japan
the following test compared the performance of G-ænial Bond to other 1-step self-etch, 2-step
self-etch and 3-step etch-and-rinse adhesives, including Clearfil SE Bond (Kuraray) and Optibond
FL (Kerr) (which are often quoted in the literature as gold standards).

Test set-up, Ultradent Method: Bovine dentine samples were polished with 320-grit Sic paper. each adhesive tested was used

according to the respective manufacturer’s instructions. Clearfil AP-X (Kuraray) was placed on the surface using an Ultradent

mould (D=2.38 mm) and light-cured. The specimens (n=5) were stored in 37°C water for 24 hours. Shear bond strength (SBS)

was measured at a cross-head speed of 1 mm/min. the statistical analysis was conducted using the tukey test (P<0.05).
