| Fine diamond burs and silicone points are best suited to smooth out concavities and uneven surfaces. |
| These are broad concavities in the ambitus that could be considered precursors to the ambulacral notches of certain mellitids. |
| In time, they would develop concavities, and would require laborious grinding to put them back into shape. |
| Perpendicularly to that axis by trying to depress the convexities and protrude the concavities, on a collapsed spinal column. |
| The shape of Taormina is a geometry of interlocking and contrapuntal curves and concavities with various centres and focal points. |
| The light from above distorts in the concavities formed at the points on which the strider rests. |
