Abstract

This study aims to examine the biomechanical factor underlying the origin of Non-Carious-Cervical-Lesions by examining the strain distribution in the enamel and dentine. A digital moire interferometry was utilized for this purpose. It is observed from this study that the enamel displayed marked strains in the lateral direction, while the dentine experienced marked strains in the axial and lateral directions during compression. The strains in the enamel and the dentine displayed both normal and shear components. The shear strain in the lateral direction within the enamel and the normal and shear strains in the axial and lateral directions within the coronal dentine concentrated at the cervical region. These experiments highlights that the biting loads will contribute to the loss of hard tissue in the cervical region.
