Introduction to Teeth Formula
Teeth are unique in that they are the only organs in the body that are both mineralized and alive. Dental Formula – Introduction Dental .
Teeth are composed of three parts: the crown, the root, and the neck. The crown is the part of the tooth that is visible in the mouth. The root is the part of the tooth that is embedded in the jawbone. The neck is the part of the tooth that is attached to the root.
Teeth are formed in the jaws during the first eight weeks of development. The first teeth to form are the incisors, followed by the canines, the premolars, and finally the molars.
The primary teeth are the first teeth to erupt in the mouth. The permanent teeth start to erupt in the mouth at about six years of age
Introduction to What is a Dental Formula
A dental formula is a way of representing the arrangement of teeth in a mammal’s mouth. The formula is written in terms of the number of each type of tooth in each jaw. For example, the dental formula for a human is 2.1.2.3.
The Dental Formula is Formulated As
follows
I. The dentition of a human adult consists of 32 permanent teeth.
II. The dentition of a human infant consists of 20 primary teeth.
III. The dentition of a human toddler consists of 16 primary teeth.
IV. The dentition of a human fetus consists of 10 primary teeth.
The dental formula for humans is as follows:
I. 2 incisors (1 in the upper jaw, 1 in the lower jaw)
II. 1 canine (in the upper jaw)
III. 2 premolars (1 in the upper jaw, 1 in the lower jaw)
IV. 3 molars (1 in the upper jaw, 2 in the lower jaw)
The dental formula for a human infant is as follows:
I. 1 incisor (in the upper jaw)
II. 1 canine (in the upper jaw)
III. 1 premolar (in the upper jaw)
IV. 2 molars (1 in the upper jaw, 1 in the lower jaw)
The dental formula for a human toddler is as follows:
I. 1 incisor (in the upper jaw)
II. 1 canine (in the upper jaw)
III. 2 premolars (1 in the upper jaw, 1 in the lower jaw)
IV. 1 molar (in the upper jaw)
The Dental Formula of Man & Child
The dental formula of man & child is the same. It is 2.1.3.2.
The first number is the number of maxillary (upper) teeth.
The second number is the number of mandibular (lower) teeth.
The third number is the number of incisors (front) teeth.
The fourth number is the number of canines (cuspids) teeth.
The fifth number is the number of premolars.
The sixth number is the number of molars (back teeth).
The Dental Formula in Child and Adult
The dental formula is a formula that is used to identify the types of teeth in a person’s mouth. Dental formula in a child is different from the dental formula in an adult. The dental formula in a child is: 2 incisors, 1 canine, 2 premolars, and 3 molars. The dental formula in an adult is: 2 incisors, 1 canine, 2 premolars, and 1 molar.
The Dental Formula For Deciduous or Milk Teeth found in Children is
2 1 2
The dental formula for permanent teeth in children is
2 1 2 3 4
The first number is for the maxillary teeth (upper teeth) and the second number is for the mandibular teeth (lower teeth). The letters indicate the type of tooth:
C – Central incisor
I – Incisor
P – Premolar
M – Molar
The central incisor is the tooth in the middle of the upper and lower arches. The incisor is the tooth in the front of the upper and lower arches. The premolar is the tooth just before the molar in the upper and lower arches. The molar is the last tooth in the upper and lower arches. Dental Formula – Introduction Dental .
The Dental Formula of Adults
The dental formula of adults is two incisors, one canine, two premolars, and three molars on each side of the mouth for a total of 32 teeth.
The Dental Formula for Permanent Teeth in Adults is
1 2 3 4 5 6 7 8 9 10 11 12
1- Central incisor
2- Lateral incisor
3- Canine
4- First premolar
5- Second premolar
6- First molar
7- Second molar
8- Third molar
9- Second lateral incisor
10- Third lateral incisor
11- First canine
12- Third canine
Three parts to the Human Mouth
The human mouth has three main parts: the lips, the teeth, and the tongue.
The Human Dental Formula is Composed of Two Parts:
The human dental formula is composed of two parts: incisors and molars. The incisors are the front teeth, while the molars are the back teeth.
Teeth and Jaw Growth
The baby teeth start coming in at around 6 months, and all 20 are usually in by about 2 years old.
The adult teeth start coming in at around 6 years old, and all 32 are usually in by about age 13.
Teeth and Jaw Growth: Causes and Effects
The physical development of teeth and jaw is determined by many factors including genetics, nutrition, and health. Poor oral hygiene and diet can lead to tooth decay and gum disease. Infection and inflammation can cause problems with jaw growth and tooth development.
