[Age-related enamel features in healthy and decayed teeth]
1Voronezh State Medical Academy named after N.N. Burdenko, Voronezh, Russia.
Summary
This study examined age-related changes in tooth enamel structure, finding differences in both healthy and decayed teeth. Compensatory reactions were observed in nearly half of all observed cavities.
Area of Science:
- Dental research
- Structural biology
- Gerontology
Background:
- Tooth enamel is the hardest substance in the human body.
- Dental caries (cavities) is a prevalent oral disease.
- Age can influence the structural integrity and health of dental tissues.
Purpose of the Study:
- To investigate age-related variations in the structural characteristics of healthy and decayed tooth enamel.
- To understand how aging affects enamel's response to carious lesions.
Main Methods:
- The study involved 125 participants across various age groups.
- Participants were categorized into subgroups based on age.
- Both intact teeth and teeth affected by dental caries were analyzed.
Main Results:
- Significant age-related differences in enamel structure were identified.
- Compensatory reactions were observed in 43.3% of analyzed caries sites.
- These findings suggest an adaptive response in enamel over time.
Conclusions:
- Enamel structure exhibits age-dependent variations.
- The development of compensatory mechanisms in response to caries is influenced by age.
- Further research can explore these age-related adaptations for improved dental treatments.

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...

Bone Disorders

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...

Tooth Anatomy

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...

The Effect of Aging on Tissues
4.1K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Oral Cavity

The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...
