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.
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...
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...
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...
Assessment of the Mouth01:26

Assessment of the Mouth

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
Healthcare Associated Infections II: Preventive Measures01:22

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Summary

Current oral health promotion may not reduce social inequalities. A clear, science-based dietary message for dental and nutrition professionals could improve oral health equity by addressing inconsistent advice.

Area of Science:

  • Oral Health
  • Public Health
  • Health Promotion

Background:

  • Social inequalities in oral health persist despite current promotion activities.
  • Existing dietary messages for oral health are often inconsistent and ambiguous.
  • A unified approach is needed for dental and nutrition professionals.

Purpose of the Study:

  • To evaluate the effectiveness of current oral health promotion in reducing social inequalities.
  • To provide a clear, common message for dental and nutrition professionals regarding the biological aspects of caries and erosion.
  • To reduce social inequalities in oral health through improved communication.

Main Methods:

  • Literature review on current oral health promotion strategies.
  • Analysis of the aetiology of caries and erosion.

  • Development of a unified dietary message for health professionals.
  • Main Results:

    • Current oral health promotion activities show questionable effectiveness in reducing social inequalities.
    • Inconsistent and ambiguous dietary messages are prevalent in the evidence base.
    • A clear, common, and unambiguous scientific dietary message can be formulated.

    Conclusions:

    • A clear, science-based dietary message can enhance the effectiveness of oral health promotion.
    • Addressing ambiguity in dietary advice is crucial for improving oral health equity.
    • Unified communication strategies can help reduce social disparities in oral health.
