When does mixed dentition begin
With eruption of first permanent teeth

6 years old
What age range do permanent incisors erupt?
6-9 years
What age range do the permanent canines and premolars erupt?
9-12 years
When does mixed dentition end?
At the exfoliation of the last primary tooth
At approximately what age do the permanent second molars erupt?
12 years
At what age range do the permanent third molars erupt?
17-21 years
When does the hard tissue of primary teeth start to form?
4-6 months in utero
When are the primary crowns completely formed?
3 1/2 months to 11 months old
What is the order of primary eruption of teeth
Mandibular Incisors Maxillary Incisors First Molars Canines Second molars
When is the root formation complete on primary teeth?
1 1/2 to 3 years old
The difference between the combined mesiodistal widths of the deciduous cuspids and molars and their successors.
Leeway Space
The spacing between the primary canine and primary first molar that normally occurs in the anterior primary dentition in children
Primate Space
Anterior roots of primary anterior teeth bend in this direction
Labially
This area is prominent on primary molars
Mesial Cervical ridge
Which primary molar is larger?
Second
Why are the roots of primary teeth are very divergent?
To make room for forming adult premolars within the jaw bones
Primary incisors are longer incisocervically than mesiodistally except these
Maxillary Central
Only primary tooth where the mesial contact of the crown is more cervical than distal.
Maxillary Canine
Only primary tooth where the mesial cusp ridge is longer than the distal
Maxillary Canine
This gives maxillary canines a concave āSā shape
Pronounced labial and lingual cervical bulge
Primary second molars resemble what permanent molars
First molars
This is the largest cusp on the primary second molar
Distal Buccal
These primary teeth resemble no other tooth
First molars
This cusp may be absent in primary maxillary first molars
Distolingual
The primary maxillary first molar has this type of groove pattern
H shaped
Molar pulp chambers are located mostly in this area
Crown
Which teeth are succedaneous?
The ones that replace primary teeth. 4-13 and 20-29
Which teeth erupt from 6 to 9 years of age?
First Molars and Incisors
Which teeth erupt from 9 to 10 years of age?
Mandibular Canines
What teeth erupt from age 10 - 12?
Maxillary canines, premolars and Second Molars
When does the hard tissue of permanent teeth begin to form?
Birth to 3 years old
7-10 years old for third molars
When are the crowns completely formed for permanent teeth?
Eruption date minus 3 years
When are the roots of permanent teeth completely formed?
Eruption date plus 3 years
