Analysis of shear bond strength of two different types of ‎bonding agents on different types of tooth substrates in ‎different periods of time
Mustafa, Ammar A. / Junaidi, M Termidzi / Khalil, Maan Ibrahim / Akhtaruzzaman, Mohd
The current study was to investigate the early shear bonding strength of two types of ‎bonding agents on different tooth substrates and to compare the results by SEM, AFM ‎and microradiography. Bonding strength of two bonding agents; 3M ADPER Single ‎Bond and OptiBond Solo adhesive system Kerr were investigated at three periods on ‎enamel, prepared enamel and prepared dentin of 240 teeth by Universal testing machine. ‎Specimens were tested under SEM for the measurement of embedment of the bonding ‎material into the tubules of the substrate. The same specimens were reevaluated by AFM ‎and micro-radiography. Shear bond strength test found no significant differences among ‎the tissues or adhesive systems. The Single Bond system formed an authentic hybrid layer ‎that can ensure adequate adhesion. OptiBond Solo showed bonding of composite to ‎dentin and enamel reinforced by mechanical interlocks of the hybrid layer. SEM gave the ‎better reliable image to estimate intrusion of the polymer into dentinal tubules.

Keywords: shear bond strength, bonding agents, SEM, AFM, 2D optical analyser
