Genetic Diseases of the Teeth. Genetic diseases are caused by gene mutations that are inherited from one or both parents. Certain genetic diseases can cause abnormalities in the teeth, affecting the rate of development of primary (baby) and secondary (adult) teeth or their physical characteristics. Often, these genetic diseases affect the normal growth and health of other parts of the body, as well.

Osmium is a hard but brittle metal that remains lustrous even at high temperatures. It has a very low compressibility. Correspondingly, its bulk modulus is extremely high, reported between 7002395000000000000â 395 and 7011462000000000000â 462 GPa, which rivals that of diamond (7011443000000000000â 443 GPa).
