Teeth01:15

Teeth

1.4K
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...

Tooth Anatomy

1.8K
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...

Bone Disorders

5.0K
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 Effect of Aging on Tissues

3.1K
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...

Essential Minerals for Bone Health01:31

Essential Minerals for Bone Health

5.6K
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...

Changes in the Appendicular Skeleton with Age

3.2K
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...

Summary

Sarcopenia, a condition of muscle loss, is linked to increased rates of periodontal disease and tooth loss. Individuals with sarcopenia showed higher prevalence of periodontitis and fewer natural teeth, highlighting a significant oral health connection.

Area of Science:

  • Gerontology
  • Oral Health
  • Nutritional Science

Background:

  • Sarcopenia, characterized by age-related loss of skeletal muscle mass and function, is a growing public health concern.
  • Periodontal disease and tooth loss are prevalent oral health issues, particularly in older adults.
  • The relationship between sarcopenia and oral health, specifically periodontal disease and tooth loss, requires further investigation.

Purpose of the Study:

  • To investigate the association between sarcopenia and the prevalence and extent of periodontal disease.
  • To determine if tooth loss is more common in individuals with sarcopenia.
  • To explore the relationship between muscle mass index and oral health indicators.

Main Methods:

  • A cross-sectional analysis of 8,053 males and 10,729 females aged 18+ from the Korean National Health and Nutrition Examination Survey (2008-2011).
  • Appendicular skeletal muscle mass was assessed, and muscle mass index was calculated (appendicular muscle mass/height squared).
  • Sarcopenia was defined using established cutoff values for males (7.0 kg/m²) and females (5.4 kg/m²); oral health and tooth loss were evaluated.

Main Results:

  • Participants with sarcopenia exhibited less frequent tooth brushing.
  • Periodontitis prevalence was significantly higher in individuals with sarcopenia (males: 30.3%, females: 45.9%) compared to those without (males: 18.3%, females: 17.4%).
  • Sarcopenia was significantly associated with a lower number of natural teeth, with adjusted odds ratios for having <20 teeth ranging from 1.96 to 2.86 for males and females, respectively.

Conclusions:

  • Tooth loss is significantly associated with sarcopenia.
  • The findings suggest a link between reduced muscle mass and poorer oral health outcomes, including periodontitis and tooth loss.
  • Further research is warranted to understand the underlying mechanisms and potential interventions.
