- Background: There are several techniques can be used on dental adhesive system which are dry, wet, and rewetting technique. However, it is difficult to achieve good bond strength between composite restoration and dentine tissue compared with enamel. Chitosan is a natural polymer hydrophilic polysaccharide, derivate from chitin, it has natural bonding ability. Objectives: The purpose of this study is to determine shear bond strength of several dentine adhesive system which are dry, wet, and rewetting bonding technique using chitosan 2% solution. Methods: This experimental study used 15 samples of free caries first-premolars teeth. Teeth soaked in normal saline solution before cut straight up to 2 mm above CEJ. Samples divided into three groups. Dentine surface treated with dry bonding technique for the first group, wet bonding technique for the second group, and rewetting technique using chitosan 2% for the last group. Samples tested for shear bond strength using LLOYD Testing Machine with a speed of 0.5 mm/minute. The data were analyzed using one-way ANOVA statistic test. Results: The average shear bond strength of three groups are, 6.919 MPa, 17.818 MPa, and 11.528 MPa for groups 1, 2, and 3. The highest shear bond strength is in group 2, which is the wet bonding technique. There is significant shear bond strength difference between the three groups, that is p=0.000 (p<0.005). Conclusion: The best shear bond strength between the three bonding technique is the wet bonding technique. Chitosan 2% solution used in rewetting technique of this study don’t have significant effect on raising shear bond strength between dentine and dental composite.
