ABSTRACT
The aim of the study was to compare In-vitro the micro tensile bond strength of sixth generation (Clearfil SE Bond, Kuraray, Japan), seventh generation (Adper Easy One, 3 M ESPE, Germany) and eighth generation ((Futurabond DC, Voco, Germany) dentin bonding agents. Twenty freshly extracted caries free, unrestored human molars were selected. The occlusal surfaces were ground flat; divided into four groups of five each according to the bonding agent applied and covered with composite resin (10 mm in height). The teeth were sectioned into one mm thick specimens with a cross sectional area of 1 mm square in hard tissue microtome and subjected to tensile force in a universal testing machine. The highest strength was seen in 8th generation bonding agent (Futura bond DC, Voco, Germany) 34.9332 MPa followed by 6th generation bonding agent 32.3477 MPa (Clearfil SE Bond, Kuraray dental, Japan) and the 7th generation agent 31.8826 MPa (Adper Easy One, 3M ESPE, Germany) respectively. The eighth generation dentin bonding agent appeared to be more advantageous in bonding than sixth and seventh generation dentin bonding agents.
