Tooth Anatomy01:21

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 grinding food.
Minerals01:26

Minerals

Minerals are essential nutrients that the human body needs in small amounts to work properly. They play a vital role in many bodily functions, such as building strong bones and transmitting nerve impulses. Some minerals are needed for hormone production or to maintain a normal heartbeat. Major minerals include calcium, phosphorus, potassium, sulfur, sodium, chlorine, and magnesium, while trace minerals include iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium.
Teeth01:15

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 and...
Standard Electrode Potentials03:02

Standard Electrode Potentials

On comparing the reactivity of silver and lead, it is observed that the two ionic species, Ag+ (aq) and Pb2+ (aq), show a difference in their redox reactivity towards copper: the silver ion undergoes spontaneous reduction, while the lead ion does not. This relative redox activity can be easily quantified in electrochemical cells by a property called cell potential. This property is commonly known as cell voltage in electrochemistry, and it is a measure of the energy which accompanies the charge...
Essential Minerals for Bone Health01:31

Essential 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...
The Oral Microbiota01:27

The Oral Microbiota

The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...

Summary

Zinc is vital for health but excessive intake, often from dental products like denture adhesives, can cause neurological issues. This review examines zinc

Area of Science:

  • * Physiology and Pathophysiology of Trace Elements
  • * Neurology and Endocrinology

Background:

  • * Zinc is essential for numerous physiological processes, including immune function, cell growth, and protein activity.
  • * While zinc deficiency is common, excessive zinc intake poses health risks, particularly in neurological disorders and diabetes.
  • * Dental materials, including denture adhesives, mouthwashes, and toothpastes, are common sources of patient exposure to zinc.

Purpose of the Study:

  • * To review the role of zinc in human physiology and its pathophysiological implications.
  • * To highlight the significance of zinc exposure in dental practice.
  • * To discuss case reports on neurological effects linked to excessive zinc from denture adhesives.

Main Methods:

  • * Literature review of scientific articles and case reports.

  • * Analysis of zinc's physiological and pathophysiological roles.
  • * Examination of zinc-containing dental products and their implications.

    • Main Results:

    • * Zinc is crucial for normal bodily functions but can be detrimental in excess.
    • * Excessive zinc intake has been linked to neurological adverse effects in patients using high-quantities of zinc-containing denture adhesives.
    • * Dental professionals must be aware of the potential risks associated with zinc in oral care products.

    Conclusions:

    • * Zinc's dual role in health and disease necessitates careful management of intake.
    • * The use of zinc-containing dental products, especially denture adhesives, requires professional attention due to potential neurological risks.
    • * Further research and professional awareness are needed regarding zinc exposure from dental materials.
