Proving a Person is Older than 18 Years Based on the Periodontal Space (Ligament) and Root Pulp of Lower Wisdom Teeth from Imaging

by

Recently, four articles that have been published on this site regarding using wisdom teeth as seen in an image from either panoramic x-ray or Magnetic Resonance Imaging (MRI) to estimate age: 1) forensic age estimation using wisdom teeth, 2) using panoramic x-rays of lower wisdom teeth to legally prove if someone is older than 18 years and 21 years, 3) Using lower wisdom teeth developmental stages determined from panoramic x-rays to calculate age, and 4) dental age estimation using MRI of wisdom teeth. From these studies discussed their appears to be a need to further explore using the so called Olze methods from Olze et al., “Evaluation of the radiographic visibility of the root pulp in the lower third molars for the purpose of forensic age estimation in living individuals,” in the International Journal of Legal Medicine, vol. 124, pp. 183–186, 2010, and Olze et al., “Assessment … Read more

Dental Age Estimation Using MRI of Wisdom Teeth

by

Recently, three articles have been published on this site regarding using wisdom teeth to estimate age: 1) forensic age estimation using wisdom teeth, 2) using panoramic x-rays of lower wisdom teeth to legally prove if someone is older than 18 years and 21 years , and 3) Using lower wisdom teeth developmental stages determined from panoramic x-rays to calculate age. All such articles use panoramic x-rays of wisdom teeth in order to attempt to estimate the age of the person they came from. However, recently there has also been articles describing using Magnetic Resonance Imaging (MRI) of wisdom teeth to predict age. One article is by Baumann et al. “Dental age estimation of living persons: Comparison of MRI with OPG,” Forensic Science International, vol. 253, pp. 76–80, 2015. Another article is by Guo et al. “Dental age estimation in living individuals using … Read more

Using lower wisdom teeth developmental stages determined from panoramic x-rays to calculate age

by

Recently, two articles have been published on this site regarding forensic age estimation using wisdom teeth and using panoramic x-rays of lower wisdom teeth to legally prove if someone is older than 18 years and 21 years. In the first study the age of a person was determined from wisdom teeth x-rays based on four stages of the emergence of a wisdom tooth using both upper and lower wisdom teeth. In the second study the age of a person was determined from wisdom teeth x-rays based on the presence and extension of periodontal space (periodontal ligament) and also the presence of root pulp of lower wisdom teeth based on four stages. In order to explore more precise predictions of the age of a person using wisdom teeth x-rays, a study was conducted using several radiological measurable findings in an article … Read more

Many times young children who travel to the U.S. are migrants seeking asylum but there age is not known. Different laws apply to those who are adults versus those who are children.

Digangi published June 1, 2018, in MedicalXpress, there have been reports of Immigration and Customs Enforcement (ICE) using dental x-rays to attempt to determine the age of the migrant. The issue at hand is whether or not dental x-rays can provide information regarding the age of a person in regards to looking at wisdom teeth and if it is safe for use. Of course when … Read more
