A comparative evaluation of the bonding efficacy of two-step vs all-in-one bonding agents - An in-vitro study.
OBJECTIVE
Aim of this in vitro study was to compare the tensile bond strength of UniFil Bond (GC America) vs iBond (Heraeus Kulzer) in conjunction with light cure composite resin (Venus, Heraeus Kulzer).


METHODS
Sixty mandibular molars were taken and divided into 3 groups which were treated with UniFil Bond, iBond and no adhesive respectively. The tensile test was performed using an Instron machine.


RESULTS
The results showed that multibottle systems (UniFil Bond, i.e., two-step)performed 30% better as compared with single bottle systems (all-in-one, i.e., one-step bonding agents).


CONCLUSIONS
It can be concluded that UniFil Bond (Multibottle system - 6(th)generation type I) performed better than iBond (Single Bottle system - 7th generation.
