A baby boy aged two years is admitted to play school and passes through a dental check - up. The dentist observed that the boy had twenty teeth. Which teeth were absent?
- Canines
- Pre-molars
- Molars
- Incisors
The Correct Option is B
Approach Solution - 1
Approach Solution -2
Explanation:
In a two-year-old child, the primary or deciduous teeth also known as baby teeth begin to develop, and by this age, a child usually has a complete set of 20 primary teeth. The primary dentition consists of:
- Incisors (front teeth): 8 teeth (4 upper and 4 lower)
- Canines (pointed teeth next to incisors): 4 teeth (2 upper and 2 lower)
- Molars (flat teeth at the back): 8 teeth (4 upper and 4 lower)
Therefore, two-year-old's have primary incisors, canines, and molars, but the premolars are absent.

Concepts Used:
Digestion and Absorption - Alimentary Canal
Digestion can be defined as the process of breakdown of large, insoluble and complex food molecules into smaller ones for its absorption and circulation in the body. This process involves the usage of a variety of digestive fluids and enzymes, including saliva, mucus, bile and hydrochloric acid, among others.

The alimentary canal is mainly referred to as the pathway by which food enters our body and moves out through the anus after digestion. It is a tube-like structure that starts from the mouth and ends in the anus. The alimentary canal plays a primary role in human digestion and is also termed as the digestive tract.
Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract.
