Introduction: The purpose of the study was to compare the shear bond strength of orthodontic brackets using such high intensity LED and comparing with the standard LED by using two different bonding primers. Material and methods: One hundred twenty Maxillary premolars that had been extracted for orthodontic treatment was used in this study. The samples were randomly divided in 6 groups of 20 specimens each based on different curing and bonding method. The shear bonding test was performed using a universal testing machine. The maximum shear force necessary to debond each bracket was recorded in Newton and then converted into Mega pascal (MPa). Results: There was highly statistical significant difference (p<0.001) found among all groups. Group V (Transbond XT -20 seconds) have the highest shear bond strength followed by Group VI (Assure resin -20 seconds). Lower the exposure time, lo.. Read More»
