American Board of Forensic Odontology (A.B.F.O.) Study of Third Molar Development and Its Use as an Estimator of Chronological Age
NCJ Number 141742
Data collected on caucasians living in the U.S. and Canada were examined by the American Board of Odontology to evaluate the accuracy of estimating chronological age from the developmental status of third molars as viewed radiographically.
The total sample consisted of 823 cases. Subjects’ age at examination ranged from 14.1 to 24.9 years; 74 percent of the records were panoramic radiographs, the others were periapical films. The sample was nearly evenly divided between males and females, but 80 percent were white, 19 percent black, and 1 percent from another ethnic group or unidentified. The results showed that maxillary third molar formation was slightly advanced over mandibular third molars, and root formation occurred earlier in males than females. The Board tabulated mean and median ages for third molar formation using an eighth- grade classification. The third molar is not an ideal developmental marker because it is frequently congenitally absent, malformed, impacted, or extracted. It is also the most variable tooth in terms of size, time of formation, and time of eruption. Despite the drawbacks of using the third molar as a marker, there are situations where its formation is the only usable datum for age estimation. 3 figures, 5 tables, and 56 references

Forensic Odontology Job Description
Forensic Odontologist: Definition, Responsibilities & Salary
Career Definition of a Forensic Odontologist
Highly trained dental specialists who participate in criminal investigations are called forensic odontologists. They help identify the source of dental evidence. This can involve making molds of teeth impressions so that they can identify who left those marks. In their role they may also extract saliva that can be used as evidence or to provide DNA. In some cases they may be required to attend autopsies when conventional identification methods are not feasible. In these cases they may be responsible for taking X-rays and creating a detailed report on the person’s teeth. This can involve measuring teeth size and identifying dental implants or dental work that has been done.
Forensic odontologists may also be involved with other types of criminal investigations. They may perform examinations to identify injuries that a person has received as the result of abuse or assault. They may also play a role in identifying the victims of disasters or terrorist attacks. Forensic odontologists may be required to testify in court. As part of their duties they also photograph teeth and relevant evidence, such as bite marks.

There are many steps involved in becoming a forensic odontologist. Forensic odontologists must attend dental school and earn a doctoral degree. They need practical experience, which can be gained through completing a residency in forensic odontology. With the required experience they can earn an American Board of Forensic Odontology certification.
It is important for forensic odontologists to pay attention to details because it is crucial that they take exact measurements and have the proper information to identify bodies from dental records. They also need to be thorough so that they locate all relevant evidence, such as DNA that may be left in a bite mark. Communication skills are important to effectively explain their work and how they reached their conclusions in court in a way that the jury can understand. They need to be objective to make scientifically based conclusions. Since they often work on difficult cases involving mass casualties or decomposed bodies they need to have a strong stomach and the ability to stay focused on their work in difficult work environments. Investigative skills are important in their work since they are searching for answers.
Career Outlook and Salary
The U.S Bureau of Labor Statistics (BLS) classifies for forensic odontologists in the category ‘dental specialists, all other’. According to the BLS, as of 2019 dentists in that category earned a median annual salary of $147,220. During the ten-year period from 2019 to 2029 they are expected to see no job growth. Which is the average rate of job growth for all occupations the BLS expects during the same ten-year period.
If a career as a forensic odontologist sounds appealing then you may also be interested in other dental specialties, such as orthodontia and oral surgery, but if you’re more interested in forensics you may want to consider being a coroner or a wildlife forensic scientist.
