Microscopes facilitate observation of microscopic crack lines that may show minimal color contrasts against a desiccated tooth surface [Figure 12], without needing trans-illumination or dyes to observe crack lines. Microscopically precise tactile sensation permits verification of a crack by associating the tactile sensation of an explorer tip falling into a cleft with the microscopic point on a crack line where the tip is located. Microscopes permit detecting microscopic amounts of debris in the cleft, or microscopic differences, in the respective directions of movement, of separate tooth structures shifting independently of one another around a cleft [Figure 13]. Stripping a microscopically thin layer from a surface with a deep craze line may reveal uncracked underlying tooth structure, indicating that the crack is superficial.
Obesity is another major cause of dry, cracked heels. When the weight of the body increases, it increases pressure on the foot. As a result, the feet expand, and this can lead to dry and cracked heels.
Dehydration is yet another cause of cracked heels. If your water intake is less than 8 glass of water a day, the skin becomes dry and dull. The very first visible effect of dehydration is cracked heels. However, excessive exposure to water can cause the skin to lose its natural oils. This also results in dehydration and thus, dry, cracked heels.
It may seem hopeless when your pool is green and full of chunky algae. But the truth is that there is almost always another option. All it takes is patience, some elbow grease, and a commitment to work on your pool almost daily for up to two weeks. 1e1e36bf2d
