Which teeth are Accessional?
accessional teeth the permanent molars, so called because they have no primary tooth predecessors in the dental arch. See also succedaneous teeth. anterior teeth the teeth in the anterior parts of the dental arches; the incisors and canines.
How do you read a dentition?
In each set, incisors (I) are indicated first, canines (C) second, premolars (P) third, and finally molars (M), giving I:C:P:M. So for example, the formula 2.1.2.3 for upper teeth indicates 2 incisors, 1 canine, 2 premolars, and 3 molars on one side of the upper mouth.
What are the stages of dentition?
Permanent teeth
- First molars – between 6 and 7 years.
- Central incisors – between 6 and 8 years.
- Lateral incisors – between 7 and 8 years.
- Canine teeth – between 9 and 13 years.
- Premolars – between 9 and 13 years.
- Second molars – between 11 and 13 years.
Which teeth numbers are Succedaneous?
In each quadrant there are five permanent teeth (central, lateral, canine, & premolars) that succeed or take the place of the five primary teeth (central, lateral, canine, & molars), they are called succedaneous teeth.
When is the bell stage?
Bell stage (+ bud of permanent tooth) The term ‘bell’ is derived from the shape of the basal lamina between the inner enamel epithelium and the outer cells of the papilla. This is a saggital section through a foetal head showing both upper and lower incisors at the bell stage of development.
What are the six stages of tooth development?
Tooth development is commonly divided into the following stages: the initiation stage, the bud stage, the cap stage, the bell stage, and finally maturation.
Which tooth is non Succedaneous?
The succedaneous teeth are the permanent teeth that replace the deciduous teeth. Permanent molars are not succedaneous teeth because they do not replace any primary teeth. Succedaneous teeth originate from successional laminae whereas permanent molars originate from the general dental lamina.
Are maxillary molars Succedaneous?
Maxillary canines, 11 years. Second molars, 12 years. Third molars, 17 years. The permanent incisors, canines, and premolars are called succedaneous teeth because they replace (succeed) the primary teeth.

Below is the sequential naming pattern of Universal Numbering System as designated by ADA: Number 1: 3rd Molar commonly known as wisdom tooth Number 2: 2nd Molar Number 3: 1st Molar Number 4: 2nd Bicuspid also known as 2nd premolar Number 5: 1st Bicuspid or 1st premolar Number 6: Cuspid or canine Number 7: Lateral incisor (upper right)
What is the American Dental Association universal numbering system?
