Summary
Dental age estimation using panoramic radiography offers a reliable method for determining chronological age. A modified Demirjian method adapted for the Hungarian population showed higher accuracy in specific age groups compared to the original Demirjian method.
Area of Science:
- Dentistry
- Forensic Anthropology
- Radiology
Background:
- Dental age determination is crucial for orthodontic treatment planning and forensic age estimation.
- The Demirjian method is a widely accepted technique for assessing dental development.
- Modifications of the Demirjian method have been developed for specific populations.
Purpose of the Study:
- To evaluate the association between dental age derived from panoramic radiography and chronological age in a Hungarian cohort.
- To compare the accuracy of the original Demirjian method with a modified version adapted for the Hungarian population.
- To investigate the correlation between mandibular angle measurements and age.
Main Methods:
- Selection of 199 panoramic radiographs from individuals aged 2.8 to 20.3 years.
- Dental age estimation using both the Demirjian method and a modified Hungarian-adapted version.
- Measurement of mandibular angles using image analysis software.
- Statistical analysis including SPSS software for data comparison.
Main Results:
- Mean mandibular angle values showed a decreasing trend with increasing age.
- The modified Hungarian-adapted Demirjian method demonstrated greater accuracy than the original Demirjian method in the 3-9 and 15-17.3 year age groups.
- A mathematical function was established to relate the two dental age estimation methods.
Conclusions:
- Panoramic radiography-based dental age calculation is a dependable method for estimating chronological age.
- The modified Demirjian method adapted for the Hungarian population provides more accurate dental age estimations in specific pediatric and adolescent age ranges.
- The utility of the gonial angle for age estimation in this context was not substantiated.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Radioactivity is a spontaneous disintegration of an unstable nuclide and is a random process, as all the nuclei in the sample do not decay simultaneously. The number of disintegrations per unit time is called the activity (A), which is directly proportional to the number of nuclei in the sample. The decay constant (λ) is an average probability of decay per nucleus in unit time.
