iBOND® Self Etch
Bond strength testing – University of Gießen, Germany
Status of ten self-etch adhesives for bonding to dentine of primary teeth.
Despite of all advances achieved on the prevention of childhood caries, 30 % of the milk tooth carious lesions
in 6-year old children are still not treated1. The restorative treatment of young children is subject to their
special needs: short attention span and sometimes limited compliance. Therefore, self-etch adhesives
provide some advantages in the treatment of children: reduction of application time which also reduces
the risk of cavity contamination by saliva, avoidance of potential unpleasant steps like water spray which
may lead to a better compliance. Besides that, the bonding performance needs to be sufficient to allow
reliable restorations until the physiological exfoliation of the milk teeth.
The following study by the University of Gießen demonstrates the excellent bond strength of iBOND Self
Etch on deciduous teeth.

Bond strength testing – University of Gießen, Germany
Status of ten self-etch adhesives for bonding to dentine of primary teeth.
Objective
The objective of this in-vitro study was to compare the microtensile bond strength (μ-TBS) of different self-etch adhesives to dentine
of deciduous teeth.
Materials and Methods
In the context of the study, fifty freshly extracted primary molars were primed to expose caries-free dentine. The exposed dentine areas
were bonded with the following ten adhesives: iBOND Self Etch (Heraeus Kulzer), Xeno V+ (Dentsply), BeautiBond (Shofu), Gaenial
Bond (GC), AdheSE One F (Ivoclar Vivadent), Prime&Bond NT (Dentsply), Adper Easy Bond (3M ESPE), OptiBond XTR (Kerr/Hawe),
Clearfil SE Bond (Kuraray) and G-Bond (GC). Specimens were placed in a distilled water-bath (37 °C) subsequent to bonding. After
24 hours of water storage, resin–dentine beams were cut and a total of 848 resin-dentine sticks were stressed in tensile until failure.
Fracture analysis was performed under 40 x magnification in a fluorescence microscope and under a SEM.

Conclusion
The investigation revealed different degrees of initial μ-TBS to primary dentine with iBOND Self Etch belonging to the group of adhesives
that performed most successfully.
