1. A skeletal X-ray of an unidentified individual shows complete fusion of the medial clavicular epiphysis. According to Kohler and Zimmer's criteria, this indicates an age of at least:
2. Gustafson's method of forensic dental age estimation uses six criteria visible on tooth sections. Which of the following is NOT one of Gustafson's original six criteria?
3. In forensic radiology for age estimation in adolescents, the Greulich and Pyle atlas is based on radiographs of which anatomical site?
4. A 16-year-old boy's age is disputed in a criminal case. Forensic age estimation by wrist X-ray shows complete fusion of the distal radial epiphysis. This finding corresponds to a minimum age of:
5. The LAST ossification centre in the human body to fuse (most commonly used to establish 'majority' — age 25 years) is located at:
6. A forensic dentist is asked to estimate the age of an unknown decomposed body from dental examination alone. Which dental feature is the MOST reliable single indicator of age above 35 years in an adult?
7. The iliac crest epiphysis begins to unite at approximately 14–15 years and completes fusion by 18–21 years. In the Indian medico-legal context, incomplete union of the iliac crest epiphysis on pelvic X-ray most reliably places the individual's age as:
8. A skeletal remains case requires age estimation. Radiological examination shows the medial clavicular epiphysis is partly fused with the diaphysis. Using established standards, the MOST appropriate age range for the individual at the time of death is:
9. Third molar (wisdom tooth) eruption is used for medicolegal age estimation. The major limitation of using third molar eruption as the sole criterion for establishing an age of 18 years is:
10. The Gustafson method of dental age estimation uses six criteria. Which of the following is NOT one of Gustafson's original six criteria?
11. In the forensic radiological assessment of a suspected juvenile offender, which epiphyseal site provides the MOST reliable indicator that the individual has crossed the 18-year threshold?
12. In the forensic context of age estimation in a living adolescent asylum seeker, the Greulich and Pyle (G&P) atlas is used. A key limitation of this method in the Indian forensic context is:
13. For forensic age estimation in individuals above 25 years where epiphyseal fusion is complete, the MOST reliable skeletal indicator is:
14. Demirjian's method of dental age estimation is based on assessing the developmental stage of which teeth, and what is its primary advantage over eruption-based dental age assessment?
15. A skeletal remain of uncertain identity is recovered. Radiological examination shows: clavicle medial epiphysis fusing (not yet complete), third molar roots 3/4 formed, sternal end of clavicle cartilaginous. What is the BEST estimated age range?
16. In forensic dental age estimation of an adult aged 25–70 years, Gustafson's method uses six criteria assessed histologically. Which criterion is the MOST reliable single predictor of age according to Gustafson's original study?
17. Under the POCSO Act and Indian juvenile justice framework, precise age determination of a person alleged to be under 18 years is critical. In the absence of birth certificate or school record, the prescribed sequence of age determination methods under the Juvenile Justice (Care and Protection of Children) Act 2015 (JJ Act) is:
18. A stab wound found at autopsy shows the following histological features: neutrophilic infiltrate in the wound margins, early fibroblast proliferation at wound edges, and beginning capillary budding. These findings indicate the wound was inflicted approximately how long before death?
