Teeth

Teeth

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 and...

Radioactive Decay and Radiometric Dating

Radioactive Decay and Radiometric Dating

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.

X-ray Imaging

X-ray Imaging

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with X-rays, and by 1900, X-ray was widely...

Imaging Studies for Cardiovascular System III: X-Ray

Imaging Studies for Cardiovascular System III: X-Ray

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Area of Science:

Forensic Anthropology
Radiology
Odontology

Background:

Dental age estimation is crucial for age assessment, often combined with skeletal age internationally.
While dental radiological imaging is a noninvasive technique for age estimation, its application in China is limited.
Established methods like Demirjian's are accurate but have limitations for individuals aged 18 and above.

Purpose of the Study:

To explore the potential of dental computed tomography for accurate age estimation.
To address the limitations of existing dental age assessment methods, particularly for adults.
To highlight the advantages of advanced imaging technology in forensic and anthropological contexts.

Main Methods:

Utilizing dental radiological imaging to observe age-related changes in the pulp cavity, crown, and root development.
Evaluating established dental age estimation methods, including those by Gleiser and Hunt, and Demirjian.
Investigating the application of computed tomography (CT) for enhanced precision in dental age assessment.

Main Results:

Dental radiological imaging reveals age-related changes in tooth development.
Demirjian's method shows high accuracy but is limited for individuals 18 years and older.
Computed tomography offers potential for improved accuracy and reliability in measuring pulp cavity dimensions.

Conclusions:

Dental age estimation is a valuable tool in forensic science and anthropology.
Computed tomography presents a promising, accurate, and convenient future method for dental age estimation.
Advancements in imaging technology can overcome limitations of current dental age assessment techniques.
