(III) Development & Eruption of Teeth
Reasonable reliable idea of the age can be made by examining the teeth.
Dental Examination
• The tooth eruption in oral cavity occurs when the root is almost half formed. As the root becomes longer, the crown erupts through the bone and is seen outside of the jaw in an oral cavity.
• Degree of formation of root and crown structures, the stage of eruption and the intermixture of temporary and permanent teeth are helpful in estimating age from birth to 25 years.
Dental Examination (Cont'd….)
• The x-ray of the jaw would show developmental status of unerupted teeth and the degree of root completion in erupted teeth.
• Crown and root development of the second molar, and third molar- helpful for 8 - 21 years.
Temporary Teeth
10 temporary teeth in each jaw —4 incisors,
2 canines & 4molars
(no premolars, no 3rd molar).
Temporary Teeth
Teeth Time of eruption Root calcification completes
Central incisor (Lower) 6 months (6 to 8m) 1/2 Year
Central incisor (Upper) 7 months (7 to 9m) 1/2 Year
Lateral incisor (Upper) 9 months (9 to 10m) 1/2 Year
Lateral incisor (Lower) 10 months (10 to 12m) 1/2 Year
1st Temp. Molar ]2 months (12 to 14m) 2 to21/2 Year
Canines 18 months (17 to 18m) 21/2 to 3Year
2nd Temp. Molars 24 months (20 to 30m) 3 Years
Permanent Teeth
16 permanent teeth in each jaw — 4 incisors, 2 canines,
4 premolars & 6 molars.
Eruption of permanent teeth
Teeth Time of eruption Root calcification completes
1st molar 6-7 years 9-10 years
Central incisor 6-8 years 10 years
Lateral incisor 7-9 years 11 years
1st bicuspid 9-11 years 12-13 years
2nd bicuspid 10-12 years 12-14 years
Canine 11-12 years 12-13 years
2nd molar 12-14 years 14-16 years

Space for third molar
In the back of jaw-
• In females- 15-16 years. • In males- after 16 years of age.
Radiological Assessment of Teeth Development
• Made by viewing X-ray films. • Orthopantogram- provided the facility is available. • Otherwise, X-ray of the oral cavity- Oblique
tangential view with the mouth open. • A tooth erupts in an oral cavity only when there is a
half root formation inside the jaw. • Teeth develop earlier in females in comparison to
males. • The germination centre of the third molar appears
between 7 and 9 years.
Crown and Root Development of the Third Molar
Crown Formation Age(On X-ray)
• Complete Crown Formation 15 years• Crown with 1/3rd Root Formation 16 Years• Crown with 2/3rd Root Formation 17 Years• Crown with
Complete Root Formation 18 years• Apical Closure of Root 21 years (Calcification of the root completed) The eruption and development of teeth in females takes
place 1 year earlier than males.
Some helpful notes on Calcification of teeth
• When molars erupt, the root is about 1/3 of its final length. Or in other words, when roots achieve 1/3 of their final length, the molars erupt.
• At the time of eruption the apical closure has not occurred
Orthopantogram (OPG)
Age from OPGs
• OPG of a child between 8-9 years.
• Both incisors do not have any tooth germ underneath them, indicating they are permanent. Age >8 years.
• Premolar shows a tooth germ beneath it. The germ is of the permanent tooth. This means the premolar is actually a temporary molar. Since permanent premolar has not appeared. Age <9 years.
Charting of teeth-
• Universal system- Teeth are numbered 1to 16 from right to left and 17 to 32 from lower left to lower right

Charting of teeth
• Haderup system-• It is similar to Palmer notation except that it uses a
(+) sign for upper teeth and (-) lower teeth
+8 +7 +6 +5 +4 +3 +2 +1 +1 +2 +3 +4 +5 +6 +7 +8
-8 -7 -6 -5 -4 -3 -2 -1 -1 -2 -3 -4 -5 -6 -7 -8
Charting of teeth
• FDI (Federation Dentaire Inetrnationale)-• FDI system substitutes for permanent teeth
• For temporary teeth 5,6,7and 8 numbers are used

(IV) Ossification of bones
The first step in ossification of the cartilage is
that the cartilage cells, at the point where
ossification is commencing and which is termed
a ossification center. It enlarge and arrange
themselves in rows. There are two types of
ossification centers - primary and secondary.
X-Ray Findings in Bones • In long bones, the appearance and fusion of epiphyses can be
evaluated for the purpose of age estimation. The findings can be described as:- “no fusion” “fusing” “recently fused: “fused”.
• X-ray of the hands, wrists, elbows, shoulders, feet, ankles, knees, the pelvis, and hip joints are very useful.
• The fusion of bones takes place 1 year earlier in females than in males.
X-ray Shoulder joint (AP view)(for the age group 17-18 years)
Age Appearance• 1 year head of humerus • 3 years greater tuberosity • 5 years lesser tuberosity
All these centers unite at 6 years and form conjoint epiphysis. • 11 years tip of coracoid unites at 16 yrs • 15 years tip of acromion appears,
unites with scapula at 18 years. • 19 years secondary center for sternal end
of clavicle appears unites with shaft by 21 years.
X-ray Shoulder (example)
• Head and greater tuberosity are appeared but not fused :
age <18 years.
X-ray Elbow Joint (AP view)(for the age group 5-16 years)
Age Appearance • 1year Capitulum
• 5-7years Medial epicondyle • 10 years Trochlea • 11 years Lateral epicondyle • 14 years of age the 3 centers i.e. Capitulum, Trochlea and Lateral epicondyle unite together and form a conjoint epiphysis. This
conjoint epiphysis unites with the shaft of humerus.
• 16 years of age The last centre to unite at elbow is medial epicondyle, which unites with humerus shaft.
• 5 years Head of radius (upper end), It unites at 16 years.
• 9 years Upper end of ulna, It also unites at 16 years.
X-ray elbow (example)• In the current x-
ray, all four centres (medial epicondyle, capitulum, trochlea and lateral epicondyle) can be seen separately, indicating the age is around 11yeras-14years.
Wrist Joint and hand (X-ray AP view) (for the age group 16-17 yrs)
Age Appearance • 2 years Lower end of radius• 6 years Lower end of ulna
Both unite with shafts around 19 years.
Carpal bones appearance and ossification• 2 months Capitate• 3 months Hamate • 3 years Triquetral • 4 years Trapezium, Scaphoid, Lunate • 4-5 years Trapezoid • 9-11 years Pisiform • Metacarpals Head of the first metacarpal unites at 16 years while the
heads of other metacarpals unite at 17 years (Thumb first).
X-ray Wrist (example)• Appearance of

Sternum • Sternum body has 4 centers since birth, which unite
from below -> upwards direction. 3rd and 4th parts unite at 15 years. 2nd and 3rd unite at 20 years. 1st and 2nd parts unite at 25 years.
• Manubrium unites with body of sternum at 60 years. • Tip of Xyphoid process appears at 3 years and unites
at 40 years with body of sternum.
X-ray Sternum (example 1)• Lateral view of sternum is
taken.• Middle four pieces of
sternum unite from below upwards, between 15-25 years of age and xiphoid procees fuses with at 40 years manubrium fuses with body at 60 years
• In this case, the upper two pieces have not united.
• Age– 15-20 yrs.
X-ray Sternum (example 2) • Showing
sternum and its pieces in a 16 year old male.
• The third and fourth piece have almost united.
• Age- around 15 years.
Upper limbs: summary
In the long bones of the upper limb, the first
to join is the elbow joint followed by the shoulder and wrist joints.
The carpal bones are useful for age in the 1/2 to 12 year age group.

X-ray Rt. Hip joint (AP view) • The tri-radiate cartilage
can easily be seen- age > 13 years and < 15 years of age.
• However, a very faint shadow of lesser trochanter can also be seen. Lesser trochanter appears at around 14 years.
• Opinion given was that the child was between 14-15 years.
