Question: 173: Role of enamel is to :
(1) Connect crown of tooth with its root.
(2) Masticate the food.
(3) Form bolus.
(4) Give basic shape to the teeth.
Answer: Option (2)
Explanation:
Enamel is the hard, outermost covering of the crown of the tooth.
It is the hardest substance in the human body and protects the tooth from mechanical damage during chewing.
The primary function of enamel is to help in mastication by providing a hard surface that can withstand the forces involved in grinding and crushing food.
Connecting the crown of the tooth with its root is the function of cementum.
Formation of bolus is carried out by the tongue and saliva, not by enamel.
The basic shape of the tooth is mainly determined by dentine.
Therefore, the correct role of enamel is mastication of food.
