Summary
Elemental concentrations in deciduous teeth decrease with age. This study analyzed metals like manganese and lead in teeth from children aged 5-14, finding lower levels in older children.
Area of Science:
- Environmental Health
- Pediatric Dentistry
- Analytical Chemistry
Background:
- Deciduous teeth undergo remodeling during physiological replacement.
- Elemental composition reflects these mineral structure transformations.
- Understanding elemental changes in teeth can indicate environmental exposures.
Purpose of the Study:
- To investigate age-related changes in elemental concentrations (Mn, Fe, Mg, Cu, K, Cr, Pb, Cd, Ca) in deciduous teeth.
- To determine if metal concentrations in deciduous teeth vary with children's age.
- To analyze the mineral composition of deciduous teeth during natural exfoliation.
Main Methods:
- Deciduous teeth samples were collected from 45 children (aged 5-14) in southern Poland.
- Atomic absorption spectroscopy was employed to quantify metal concentrations.
- Non-invasive collection of teeth during physiological replacement was utilized.
Main Results:
- A statistically significant decrease in the concentration of analyzed elements was observed in deciduous teeth of older children compared to younger children.
- No significant change in the total metal concentration relative to calcium content was found with increasing age.
- The constant cationic equilibrium remained stable across different age groups.
Conclusions:
- Children's age is a significant factor influencing the elemental composition of deciduous teeth.
- The study highlights a trend of decreasing metal concentrations in deciduous teeth as children age.
- Further research may explore the implications of these age-related elemental shifts.

01:15Teeth
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...

01:21Tooth 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 grinding food.

01:29Bone 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...

01:09Changes in the Appendicular Skeleton with Age
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...

01:20Complexometric EDTA Titration Curves
EDTA titration curves determine the free metal ion concentration. The titration curve represents the change in concentration of free metal ions (p function) as a function of the volume of EDTA added. This curve consists of three regions: before, at, and after equivalence points. Excess free metal ions are present before the equivalence point. Equal concentrations of metal ions and EDTA are present at the equivalence point. After the equivalence point, excess EDTA exists. This means slight...
01:31Essential Minerals for Bone Health
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
