Which of the following forms the major part of the tooth and is covered by enamel?

Options:
A Enamel
B Dentine
C Cement
D Odontoblast

The correct answer is:
Dentine

Solution:
The structure of teeth can be divided into three regions:

a) Crown: The hard chewing surface covering of the teeth is made up of enamel which helps in the mastication of food. This enamel is the hardest substance of the human body. This enamel is non-living part of tooth. Below it the living part of tooth is present which is called as ameloblast dentine and it forms enamel. This dentine covers the cavity of tooth called as pulp cavity. Canaliculi connects pulp cavity to enamel.

b) Neck: It is formed by sockets and gums.
c) Root: It forms the part of pulp cavity. The pulp cavity contains the small cavity which provides nerves and blood capillaries to teeth and it enters tooth from an opening called as apical foreman. The hollow cavity of pulp is called as root canal. The outer covering of root is called as cementum. Cementum connects the root with the jaw bone.

Which of the following functions is not performed by secretions from salivary glands?

Options:
A Digestion of complex carbohydrates
B Lubrication of oral cavity
C Digestion of disaccharides
D Control bacterial population in mouth

The correct answer is:
Digestion of disaccharides

Solution:
Salivary glands are one of the most important glands in our digestive systems which produces saliva. Saliva contains a carbohydrate digesting enzyme called salivary amylase (ptyalin). This enzyme help in the digestion of starch in the oral cavity. Starches are complex carbohydrates formed by longer saccharide chains of amylose and amylopectin.

Saliva also helps in lubrication of the buccal cavity.

Lysozymes present in saliva protects against bacterial invasion.

The digestion of disaccharides and some oligosaccharides is undertaken by a number of small intestinal brush border enzymes like sucrase-isomaltase, lactase, maltase-glycoamylase and trehalase.
