Abstract:
Deformation behavior of human dentinoenamel junction (DEJ) was studied under shear testing at room temperature. Twenty samples with flat DEJ that contained dentin and enamel in the 1:1 proportion were cut from intact human teeth. DEJ was the shear plane in the samples which were divided into two equal parts under loading. Since deformation curves of the samples with DEJ could be approximated by straight lines and the sample failure occurred through unstable growth of cracks, the deformation behavior was treated as brittle. The shear modulus and the shear strength were 0.31±0.04 GPa and 16.4±3.0 MPa, respectively. SEM examination of fracture surfaces showed that cracks propagated in both the dentin and enamel parts of the samples. Hence, the mechanical properties of dentin and enamel were similar in vicinity of DEJ. © 2016 Elsevier B.V. All rights reserved.
