What is the sequence of emergence of primary dentition?
What is the sequence of emergence of primary dentition?
In either of the maxillary and mandibular arches, deciduous dentition emerged in the following order: central incisor, lateral incisor, first molar, canine and second molar.
What are the stages of dentition?
There are 3 phases used to chart what stage a person is at in their tooth development: Primary, Mixed and Permanent dentition stages. By the age of around 12 there will be 28 teeth in the mouth and by the age of 21 all of the permanent teeth have usually erupted, that’s 32 teeth!
At what years and period does primary dentition takes place?

What is primary dentition?
The primary dentition constitutes the first teeth to erupt in the pediatric patient. Comprised of 20 teeth, they are labeled based on an alphabetical system rather than the numbering system used for permanent teeth.
What is the eruption sequence for deciduous and permanent teeth?
The first teeth to erupt are the lower and upper central incisors, which erupt between the ages of 6 12 months. The next to erupt are the lateral incisors between 9-16 months, followed by the first molars from 13-19 months. Next, the cuspids (canines) erupt from 16-23 months.
What are the types of dentition?
Humans, like most other mammals, develop two different sets of dentition called the deciduous dentition (or primary dentition, baby teeth, or milk teeth), and the permanent dentition (or secondary dentition, or adult teeth).
How many teeth are present in the primary dentition?
Development of the Primary Dentition. The primary dentition consists of 20 teeth (Figure 1). Each dental arch contains 10 teeth, namely four incisors, two canines, and four molars.
At which age will a child have 12 permanent and 12 primary teeth?
A primary tooth falls out because it is being pushed out of the way by the permanent tooth that is behind it. Slowly, the permanent teeth grow in and take the place of the primary teeth. By about age 12 or 13, most kids have lost all of their baby teeth and have a full set of permanent teeth.
Why is it important for dentists to learn the sequence of eruption of teeth for both deciduous and permanent?
The chronology and sequence of eruption of human primary and permanent teeth are important milestones during a child’s development. Estimation of eruption schedule is a very valuable tool in child’s dental health planning including diagnostic, preventive and therapeutic measures in pediatric dentistry and orthodontics.
How many teeth are in the primary dentition?
The primary (deciduous or milk) dentition comprises four incisors, two canines, and four molars in each jaw (total of 20 teeth). The normal permanent (adult) dentition comprises four incisors, two canines, four premolars, and six molars in each jaw (32 teeth).
