Background and objective: The aim of the study is to assess the correlation between degree
of monomer conversion (DC) and shear bond strength (SBS) of the different adhesives. The
objective of the present study was to determine the efficiency of four orthodontic adhesives
regarding shear bond strength (SBS), debonding characters and degree of conversion (DC)
and to correlate SBS to the DC.
Methods: Forty human upper first premolars, divided into four Groups (n = 10) were bonded
with metal brackets using four different adhesives. Brackets were debonded in shear on an Instron universal testing machine with a crosshead speed of 1 mm per minute. The mode of bond
failure was determined by the adhesive remnant index (ARI) index and the DC was determined
by fourier transform infrared spectroscopy (FTIR) analysis.
Result: There was a statistically significant difference between the SBS of only Transbond XT
and Orthobond plus color change adhesive while the two remaining adhesives showed no significant difference. All groups of the adhesives showed cohesive type of bond failure according
to the ARI results. A statistically significant lower percentage of DC was noted for Orthobond
plus (63 %) than Transbond XT (70.2 %) but it was within the accepted range reported in the
literature (55-75%). Pearson’s correlation was significantly positive between SBS and DC for
Smart Ortho, Heliosit Orthodontic and Orthobond Plus adhesives and insignificantly positive
for Transbond XT.
Conclusion: Within the limitations of this in vitro study it can be concluded that the Transbond
plus color change has significantly higher fluoride release as well as recharge properties when
compared to other ortho-adhesive material.
