Abstract: Objectives
A dental adhesive without small and hydrophilic monomers such as HEMA and
TEGDMA would be beneficial in order to avoid contact allergies. However, these
monomers are important to increase infiltration and polymerization of the adhesive.
Therefore, the purpose of this study was to evaluate the bonding effectiveness and
bond durability of a more hydrophobic and biocompatible adhesive as compared to a
conventional three-step etch-and-rinse adhesive.
Sixteen non-carious human third molars were used to determine the micro-tensile bond
strength testing (μTBS) and interfacial ultrastructure by transmission electron
microscopy (TEM) of the more hydrophobic cmf adhesive system (Saremco) adhesive
as compared to the control OptiBond FL (Kerr).
The more hydrophobic and biocompatible three-step etch-and-rinse adhesive was able
to produce a reasonable short-time bonding effectiveness. On the long-term, the
collagen fibrils in the hybrid layer were not effectively protected and were prone to
hydrolytic degradation. As a result, long-term bonding effectiveness of this novel
adhesive was very low.
Application of a more hydrophobic adhesive without altering the application procedure
considerably results in a reduced durability of the created bond
Clinical relevance
Omitting small and hydrophilic components from the adhesive formulation may impair
the durability of your composite restoration.
