Question

White enamel of our teeth is:
A) \[{\text{C}}{{\text{a}}_{\text{3}}}{\left( {{\text{P}}{{\text{O}}_{\text{4}}}} \right)_{\text{2}}}\]
B) \[{\text{Ca}}{{\text{F}}_{\text{2}}}\]
C) \[{\text{CaC}}{{\text{l}}_{\text{2}}}\]
D) \[{\text{CaB}}{{\text{r}}_{\text{2}}}\]

Answer 1

Hint: We have to know that in the human body, teeth are made up of enamel. Enamel is one of the major tissues in the human body. Enamel is used to cover teeth. It is also used to cover the crown. Our human tooth is made up of four major tissues. There are enamel, dentin, cementum and dental pulp.

Complete answer:
In human beings, enamel of teeth is the hardest substance in the body made up of\[{\text{Ca}}{{\text{F}}_{\text{2}}}\]. The dentine is also one of the parts of teeth. It is made up of \[{\text{C}}{{\text{a}}_{\text{3}}}{\left( {{\text{P}}{{\text{O}}_{\text{4}}}} \right)_{\text{2}}}\].
From above discussion we conclude,
Hence, white enamel of our teeth is \[{\text{Ca}}{{\text{F}}_{\text{2}}}\].
Option A is not correct, because White enamel of our teeth is not \[{\text{C}}{{\text{a}}_{\text{3}}}{\left( {{\text{P}}{{\text{O}}_{\text{4}}}} \right)_{\text{2}}}\].
Option B is correct, because White enamel of our teeth is \[{\text{Ca}}{{\text{F}}_{\text{2}}}\].
Option C is not correct, because White enamel of our teeth is not \[{\text{CaC}}{{\text{l}}_{\text{2}}}\].
Option D is not correct, because White enamel of our teeth is not \[{\text{CaB}}{{\text{r}}_{\text{2}}}\].

Note:
As we know that there are four types of human beings. There are incisors, canines, premolars and molars. There are two jaws in my mouth. These jaws are divided by four types. There are the right upper right jaw, upper left jaw, right lower jaw and left lower jaw. Each segment of mouth has two incisors, one canine, two premolar and three molars including one wisdom tooth. In the upper jaw having four incisors, two canines, four premolars and six molars including two wisdom teeth. For our entire mouth having eight incisors, four canines, eight premolars and twelve molars including four wisdom teeth in the human body.
