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.
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...
Oral Cavity01:11

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...
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.
Detergent Purification of Membrane Proteins01:18

Detergent Purification of Membrane Proteins

Detergents are used to purify the integral proteins of the membrane. The hydrophobic portion of the detergent can replace membrane phospholipids while solubilizing the membrane proteins. When detergent monomers reach a specific concentration in a solution called critical micelle concentration (CMC), they form micelles. Above CMC, the concentration of the detergent monomers remains in equilibrium with the micelle. The number of detergent monomers present in the CMC varies for each detergent, and...
Hand hygiene01:23

Hand hygiene

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Published on: December 26, 2016

Area of Science:

  • Geriatric Medicine
  • Infectious Disease Prevention
  • Dental Material Science

Context:

  • Denture hygiene is crucial for immunocompromised and bedridden individuals to prevent aspiration of pathogens.
  • Chemical denture cleansers are recommended for daily home use alongside mechanical cleaning.
  • Concerns exist regarding chemical cleansers damaging denture materials due to aggressive formulations.

Purpose:

  • To evaluate the safety and efficacy of modern, neutral to weakly alkaline chemical denture cleansers.
  • To assess the contribution of chemical cleansing to overall denture hygiene in care facility residents.
  • To address misconceptions about denture cleanser material compatibility.

Summary:

  • Over-the-counter denture cleansing tablets in Germany are typically neutral or weakly alkaline peroxides, differing from older, aggressive formulations.
  • In vitro studies demonstrate that regular chemical cleansing by nursing staff is an effective and easy method to enhance denture hygiene.
  • This method complements mechanical cleaning without causing damage to denture materials, especially for care facility residents.

Impact:

  • Chemical denture cleansers offer a safe and effective adjunct to mechanical cleaning, reducing infection risks in vulnerable populations.
  • Regular use of appropriate chemical cleansers can improve the oral health of residents in care facilities.
  • Dispels myths about denture material damage, promoting wider adoption of effective hygiene practices.
