Tooth Anatomy01:21

Tooth Anatomy

2.1K
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...

Aging01:26

Aging

643
Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

The Effect of Aging on Tissues

3.4K
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...

Changes in the Appendicular Skeleton with Age

3.4K
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...

Pharmacodynamics in Geriatric Patients: Effects of Age

193
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption01:22

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

259
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...

Area of Science:

  • Dentistry
  • Gerodontology
  • Dental Public Health

Background:

  • Tooth wear is increasingly prevalent across all age groups.
  • A growing number of patients are retaining their natural teeth into old age, increasing the potential for age-related dental issues.
  • Ageing populations present unique challenges for managing dental conditions like tooth wear.

Purpose of the Study:

  • To review the clinical presentation, epidemiology, and restorative interventions for erosive tooth wear.
  • To describe management dilemmas specific to aging dentitions.
  • To highlight evidence-based preventive strategies as potentially superior to extensive restorative care.

Main Methods:

  • This paper employs a narrative review methodology.
  • It synthesizes existing literature on erosive tooth wear.
  • Clinical presentation, epidemiology, and restorative interventions are examined, with a focus on aging dentitions.

Main Results:

  • Erosive tooth wear presents diagnostic and management challenges, particularly in older adults.
  • Preventive interventions are often preferable to extensive restorative care due to lower maintenance needs.
  • Patient factors, including wishes and commitment, are crucial for successful treatment.

Conclusions:

  • Successful management of erosive tooth wear in the elderly requires accurate diagnosis.
  • Preventive strategies and holistic advice on restorative interventions are key.
  • Integrating patient expectations into decision-making is essential for effective, long-term care.
