I now have all the information needed. Let me construct the complete medico-legal age estimation report with the modified FDI chart.

MEDICO-LEGAL AGE ESTIMATION REPORT

(Dental Examination - In Reply to Requisition)

To, The Medical Officer, Casualty, SJMCH, Puri

Ref: Sea Beach P.S. Case No. 19 Dt. 02/01/2024 U/S 326A IPC

DENTAL EXAMINATION REPORT

Patient: Hadu Suna S/O Bhakta Suna of Court Chakka Examined by: (Name & Designation of Dental Surgeon) Place of Examination: SJMCH, Puri Date of Examination: (imaginary date for assessment) Referred by: I.I.C. Sea Beach P.S., Puri

STEP 1 - ANALYSIS OF CLUES PROVIDED

The clues state:

Total number of teeth: 6 in each of all four quadrants (total = 24 teeth present)
3rd and 5th tooth in each quadrant are of the temporary (deciduous) set
Rest are permanent
No empty sockets in between

STEP 2 - FDI NOTATION SYSTEM (Modified)

In the FDI (Federation Dentaire Internationale) two-digit notation system:

First digit = Quadrant number (1 = Upper Right, 2 = Upper Left, 3 = Lower Left, 4 = Lower Right)
Second digit = Tooth position (1 through 8 from midline)

For temporary/deciduous teeth, the FDI notation uses:

Quadrants 5, 6, 7, 8 (or denoted with a "d" suffix / lowercase)
In the modified FDI chart, deciduous teeth in mixed dentition are often shown within the same quadrant numbering but distinguished by marking them as "T" (temporary) or encircling them.

STEP 3 - MODIFIED FDI CHART

The examination reveals 6 teeth per quadrant. In FDI terms, positions 1-6 are present in each quadrant (no 7th or 8th/wisdom teeth visible yet). The 3rd and 5th positions in each quadrant are temporary; the 1st, 2nd, 4th, and 6th positions are permanent.

KEY:  P   = Permanent tooth
     [T]  = Temporary / Deciduous tooth (shown in brackets)
     ( )  = FDI codes for deciduous teeth use 5x, 6x, 7x, 8x series

Tooth-type identification per FDI position:

Quadrant	Position 1	Position 2	Position 3	Position 4	Position 5	Position 6
UR (Q1)	11 - Perm. Central Inc.	12 - Perm. Lateral Inc.	53 - Temp. Canine	14 - Perm. 1st Premolar	55 - Temp. 2nd Molar	16 - Perm. 1st Molar
UL (Q2)	21 - Perm. Central Inc.	22 - Perm. Lateral Inc.	63 - Temp. Canine	24 - Perm. 1st Premolar	65 - Temp. 2nd Molar	26 - Perm. 1st Molar
LL (Q3)	31 - Perm. Central Inc.	32 - Perm. Lateral Inc.	73 - Temp. Canine	34 - Perm. 1st Premolar	75 - Temp. 2nd Molar	36 - Perm. 1st Molar
LR (Q4)	41 - Perm. Central Inc.	42 - Perm. Lateral Inc.	83 - Temp. Canine	44 - Perm. 1st Premolar	85 - Temp. 2nd Molar	46 - Perm. 1st Molar

(Highlighted positions 3 and 5 in each quadrant = deciduous/temporary teeth)

STEP 4 - INTERPRETATION & AGE ESTIMATION

Pattern observed: This is a mixed dentition pattern - a stage where both temporary (deciduous) and permanent teeth co-exist.

Reasoning from eruption tables (Parikh's Forensic Medicine; Essentials of Forensic Medicine & Toxicology, 36th ed.):

Tooth	Eruption (Permanent)	Implication
Position 1 (Central Incisor) - Permanent	6-8 years	Already erupted → age > 6 yrs
Position 2 (Lateral Incisor) - Permanent	7-9 years	Already erupted → age > 7 yrs
Position 3 (Canine) - Still temporary	Permanent canine: 11-12 yrs	Has NOT erupted yet → age < 11 yrs
Position 4 (1st Premolar) - Permanent	9-11 years	Already erupted → age > 9 yrs
Position 5 (2nd Premolar) - Still temporary (2nd deciduous molar present)	Permanent 2nd premolar: 10-12 yrs	Has NOT erupted yet → age < 10 yrs
Position 6 (1st Molar) - Permanent	6-7 years	Already erupted → age > 6 yrs
Positions 7, 8 absent	2nd molar: 12-14 yrs; 3rd molar: 17-25 yrs	Has not erupted yet → age < 12 yrs

Key deductions:

Permanent 1st premolars (pos. 4) have erupted → age is at least 9-10 years
Deciduous canines (pos. 3) still present, permanent canine not yet erupted → age is below 11 years
Deciduous 2nd molars (pos. 5) still present → age is below 10-12 years
No 2nd or 3rd permanent molars → age is below 12 years
No empty sockets confirms teeth are still in situ, not shed

STEP 5 - OPINION ON AGE

Estimated Age: Between 9 to 11 years

Based on the dental examination findings - specifically the mixed dentition pattern with permanent incisors (positions 1, 2), 1st premolars (position 4), and 1st molars (position 6) having erupted, while deciduous canines and second molars (positions 3 and 5) are still retained, and the absence of 2nd permanent molars - the subject Hadu Suna is estimated to be between 9 and 11 years of age, most likely approximately 10 years old at the time of examination.

The above estimation carries a margin of error of ±1 year due to individual biological variation, nutritional, and environmental factors.

STEP 6 - MEDICO-LEGAL SIGNIFICANCE

The subject is a minor (below 18 years)
This is relevant under the Protection of Children from Sexual Offences Act (POCSO) and for proceedings under the Juvenile Justice Act
Age estimation from dental development is considered the most reliable method in children up to ~14-16 years (more reliable than skeletal age)
Under Section 326A IPC (the referred section), establishing minority of the victim is a significant legal consideration
