The shape of cusps, apart from enamel thickness, is largely due to the relative growth of the inner enamel epithelium and the underlying mesenchyme [29].
This study investigates the biomechanical interactions among restorative materials, cuspal preparation designs, and cement thickness in a cusp-replacing adhesive premolar restoration.
Results: Cusp basal regions measured 0.69 to 0.86 mm in thickness, significantly thicker (P =.001) than the rest of the cusp, which measured 0.36 to 0.48 mm.
Cardiac valve calcification will be considered present when bright echoes of more than 1-mm thickness are seen on 1 or more cusps of the aortic valve, mitral valve, or mitral annulus.
The carriage speed, heading angle of the model ship, and ice thickness were varied, and the forces, accelerations, ice cusp sizes, carriage positions, and ice pile dimensions under the intact ice sheets were measured.
We therefore examined in normal aortic valve cusps the relationship between the presence of microvessels and the tissue thickness.
Enamel varies in thickness over the surface of the tooth and is often thickest at the cusp, up to 2.5mm, and thinnest at its border, which is seen clinically as the CEJ.
Variations in lithospheric thickness are supported by the correlation between the Y-shaped discontinuities and the V-shaped cusps along the south polar terrain margin and the relative surface age of the adjacent non-south polar terrain regions.
Viewed from rice straw proportion used in mulch both with the thickness of 0.5 mm and 1.0 mm, especially for mulch in wet condition, the quadratic curve with the peak/maximum cusp was formed in the proportion of 30%.
