Dental formula for monophyodont teeth of human is? Pls explain?
Such a tricky question,π€π€π€
okay,π
According to dental formula
I C PM M/I C PM M, you Know that right,,π
Primary teeth=2102/2102
Permanent teeth=2123/2123
&
At last
formula of monophyodont teeth in human is
0021/0021
What I found from
searchπ, because I knew that ,there's no monophyodont teeth occurred in human..π
Monophyodont is the first set of teeth that comes in children.
Monophydont (teeth appearing just once in lifetime) and diphydont dentition (teeth appearing twice in lifetime). Since, in humans teeth occur two times, it is generally referred as diphyodont dentition.Coming to the question, how monophydont then occurs in humans,see, as we have 20 teeth in infant and 32 in adult. The 20 teeth out of 32 in adult are the same as the 20 in infant and hence these come twice in lifetime, these are diphyodont and tge remaining 12 out of 32 that appears for the very first time later only occur in adult and were never the part of milk teeth in adult and hence these are monophyodont and in your question only demtal formula for monophydont dentition is asked.The 20 out of 32 (diphyodont) in adults include incisors, canines, 1st and 2nd molars. And the 12 out of 32 (monophyodont) in adults include 1st and 2nd premolars and 3rs molar. Therefore the dental formula for monophyodont teeth in humans comes out to be 0021/0021. (No incisors, no canines, 1st and 2nd premolars and 3rd molars.)Hope that helps!

**Dental Formula for Monophyodont Teeth of Humans**
The dental formula represents the number and types of teeth present in one-half of the upper or lower jaw of an organism. In humans, the dental formula is used to describe the teeth arrangement for one half of the mouth, as humans have bilateral symmetry.
**Definition of Monophyodont Teeth**
Monophyodont teeth refer to a type of tooth arrangement where the animal develops only a single set of teeth throughout its lifetime. Humans are monophyodont, meaning they only develop one set of teeth, commonly known as the primary or deciduous teeth, followed by the permanent teeth.
**Deciduous Teeth**
Deciduous teeth, also known as baby teeth or milk teeth, are the first set of teeth to erupt in humans. These teeth typically start to appear around six months of age and are eventually replaced by permanent teeth. The dental formula for deciduous teeth in one-half of the mouth is as follows:
2.1.2.0 / 2.1.2.0
This means that in one-half of the mouth, there are 2 incisors, 1 canine, 2 molars, and 0 premolars in the deciduous dentition.
**Permanent Teeth**
Permanent teeth begin to replace the deciduous teeth starting around the age of six. The dental formula for permanent teeth in one-half of the mouth is as follows:
2.1.2.3 / 2.1.2.3
This means that in one-half of the mouth, there are 2 incisors, 1 canine, 2 premolars, and 3 molars in the permanent dentition. The third molars, also known as wisdom teeth, may not develop in some individuals or may require extraction if they cause issues such as impaction or crowding.
**Summary**
The dental formula for monophyodont teeth in humans is:
Deciduous Teeth: 2.1.2.0 / 2.1.2.0
Permanent Teeth: 2.1.2.3 / 2.1.2.3
It is important to note that the dental formula represents one-half of the mouth, as the formula is symmetrical for both the upper and lower jaws. The dental formula provides a concise way to describe the arrangement and number of teeth in a specific species.
