Hint: The hardest substance of the body is present in our teeth. It is made up of calcium minerals and is white in color. This substance has a fIrm intercellular matrix in it.
Complete answer:
The hardest substance of the body is Enamel. It is the outer covering of the tooth and Enamel is the visible part of the teeth. Its function is to protect the tooth’s crown. It plays a major role and acts as a defense mechanism towards tooth decay.
Additional Information: Enamel is hardest, with white to off-white, and is made up of a highly mineralized substance that protects the tooth but may become prone to degradation, especially by acids that are present in the food and drink. Calcium hardens the tooth enamel. In some very rare cases, it is seen that enamel fails to form, leaving the underlying dentin exposed on the surface. As you know that the enamel is the hardest substance present in the human body, it contains the highest percentage of minerals approx 96%, with water and organic material composing the rest. The primary mineral present in enamel is the hydroxyapatite, which is crystalline calcium phosphate. Enamel is formed on the outer layer of the tooth while the tooth develops within the jaw bone before it erupts into the mouth. Once the enamel is fully formed, the enamel does not contain blood vessels or nerves and is not made of cells. Enamel rod is the basic unit of enamel.
So, the correct answer is ‘Enamel’.
Note: After enamel, the hardest substance in the human body is the bone. Bone is made up of calcium phosphate and collagen. Enamel is the second hardest substance in the whole world after the diamond. The light can pass through enamel as it is translucent.
