( ): Standard deviation
From this study it can be concluded that GC UniFil Bond exhibited no significant
variation in bond strengths despite variations in dentine location for the teeth tested.
Although not statistically significant, GC UniFil Bond specimens bonded parallel to the
tubule orientation produced slightly higher adhesive strengths than those specimens
bonded perpendicular. These results could be attributed to the increased surface
area of mineral available for chemical bonding when tubule orientation is parallel.
In contrast, Single Bond showed slightly lower bond strengths when bonded parallel
to tubule orientation and significantly lower bond strengths to mid root dentine.
