Abstract:
ABSTRACT:Duration of orthodontic treatment becomes major concern. The present study compared shear bond
strength (SBS) and adhesive remnant index (ARI) values of different adhesive systems with different
application methods on rebonding process of retrieved orthodontic brackets. Eighty premolar teeth were
equally divided into five groups. Transbond XT (TXT) which belongs to total-etch system was used in
Group 1 as the control group. Nova Compo-SF (NC) and Vertise Flow (VF) (Kerr Dental, Italy) which are
self-adhering flowable composites were used in Group 2 (NC+etch) and Group 3 (VF+etch) respectively
with additional etching before application. Group 4 (NC) and Group 5 (VF) were used by following
instructions of each brand. The brackets were debonded with a bracket removing plier and rebonded with
the same procedures after sandblasting of the bracket and surface cleaning of the enamel. SBS and ARI were
measured for each sample. Comparison between all groups was performed by Kruskal-Wallis test and chisquare test. The highest SBS was observed in NC+etch (median = 11.44, mean = 13.49±9.42), followed by
NC (median = 10.17, mean = 11.35±6.55), TXT (median = 6.36, mean = 8.06±6.33), VF+etch (median
= 5.68, mean = 6.75±4.58), and VF (median = 2.62, mean = 2.92±2.57), respectively. ARI 1 was observed
in 81.3% of TXT whereas 62.5% of NC+etch. ARI 1, 2, and 3 were equally distributed in VF+etch group
(31.3%). ARI 5 was observed in 37.5% of NC and 62.5% of VF. Analyses referred to statistically significant
differences between five groups regarding both SBS and ARI (p < 0.001). As NC showed the highest SBS
on rebonding process, it can be a promising alternative to TXT which is the gold standard.
