Summary
This study found modified Gustafson's method reliable for dental age estimation. The technique accurately determined age within ±2.64 years, showing statistical significance for forensic identification.
Area of Science:
- Forensic Odontology
- Anthropology
- Gerontology
Background:
- Establishing personal identity relies heavily on age determination.
- Teeth offer durable skeletal evidence for age assessment.
- Gustafson's 1950 method introduced six dental changes indicative of aging.
Purpose of the Study:
- To assess the reliability of a modified Gustafson's method for chronological age estimation.
- To validate the accuracy of dental indicators in determining an individual's age.
Main Methods:
- Seventy patients aged 20-65 years undergoing tooth extraction were analyzed.
- Ground sections of extracted teeth were microscopically examined.
- Modified Gustafson's criteria (attrition, translucency, dentin, cementum, resorption) were quantified.
Main Results:
- The modified method yielded a mean age difference of ±2.64 years.
- Statistical analysis confirmed a significant difference between actual and calculated ages (P < 0.05).
Conclusions:
- Gustafson's method, with proposed modifications, is a reliable tool for dental age estimation.
- The findings support the use of this technique in forensic and anthropological contexts.

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...

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
