Dental and chronological age in children under oncological treatment.

So one can argue that this is a very small, very specific population studied in this paper.  Thankfully, the number of cases of children undergoing cancer therapies such as this is small, and therefore the need to age them for forensic purposes is likely to be incredibly rare. However, the main piece around this research, published in the Journal of Forensic Science, more...

The accuracy of estimating chronological age from Demirjian and Nolla methods – Full Text

BACKGROUND: Age determination has great importance in many clinical decisions, being commonly used in odontopediatrics, orthodontics, pediatrics, and forensic medicine. The Nolla and Demirjian et al. methods have been used for these purposes. However, estimating chronological age by means of the dental mineralization stage is not a straightforward analysis, and it is more...

Mandibular canine index: A reliable predictor for gender identification using study cast in Indian population.

CONTEXT: Various methods are used for gender identification in anthropologic and forensic investigations. The canine tooth is widely used for gender determination because of its sexual dimorphism and durability in the oral cavity. Mandibular canine index (MCI) is one of the most reliable and valid predictor for gender identification. AIM: To assess the reliability of MCI more...

Child or adult bites ? – not by arch width you can’t.

Bitemarks are, sadly, often a common feature of child abuse cases. While there is an ongoing argument about the use of bitemarks, there is often a requirement to determine if an injury has been caused by an adult or a child.  I am frequently asked this question, and, when looking at the medical reports in such cases I often see: Suspected bitemark on thigh - looks small more...

Age estimation in the living: Transition analysis on developing third molars.

A radiographic assessment of third molar development is essential for differentiating between juveniles and adolescents in forensic age estimations. As the developmental stages of third molars are highly correlated, age estimates based on a combination of a full set of third molar scores are statistically complicated. Transition analysis (TA) is a statistical method more...

Kvaal et al Ageing Technique

There are many techniques for ageing individuals, some can be used on deceased and living, some just on deceased.  The Kvaal technique was published in 1995 and remains a popular method.  Based on the biological changes in pulp cavity size (caused by the result of secondary dentine deposit) the technique can be used on radiographs. Teeth generally used are maxillary more...

Reconstructing an identity from teeth.

Fascinating case report in Am J Forens Med Pathology - a case where an individual had lost their memory including their name and age.  Several attempts were made to try and identify him but to no avail - eventually a judge in Italy agreed to the assignment of a new identity to the person - but one that should rely as much as possible on available biological more...

MRI vs DPT assessment of third molars for ageing

Forensic Science International has published a paper examining the use of MRI as an alternative to panoramic radiographs.  The full citation of the paper is: Dental age estimation of living persons: Comparison of MRI with OPG Pia Baumanna, b, Thomas Wideka, Heiko Merkensa, Julian Boldtc, Andreas Petrovica, d, Martin Urschlera, Barbara Kirnbauere, Norbert Jaksee, Eva more...
