In orthodontic practice, it is essential to obtain a reliable adhesive bond between an orthodontic attachment and the tooth surface since replacing loose brackets is inefficient and time-consuming. Bond failure usually occurs as a result of stress caused by the orthodontic procedure, normal oral functions such as </span></span>mastication or due to inconsistencies in the bonding technique. Sufficient bond strength is a factor that contributes to the clinical success of orthodontic treatment. Thus, a continuous search is on for higher bond strengths adhesives. Largely the assessment of bonding agents has been done in-vitro using shear bond strength measurement. Extrapolation of results from such studies to clinical studies becomes difficult due to a large variability in the study designs.
