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.
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...
Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Summary
This summary is machine-generated.

Routine dental prophylaxis is not necessary for children to prevent cavities or gingivitis. Evidence suggests it is not warranted before professionally applied topical fluoride (PATF) or at 4-month intervals for gingivitis prevention.

Area of Science:

  • Dental hygiene and preventive dentistry.
  • Evidence-based practice in oral healthcare.
  • Public health and community dentistry.

Background:

  • This review examines the necessity of dental prophylaxis in preventive oral care.
  • Focuses on its role in caries and gingivitis prevention, particularly before professionally applied topical fluoride (PATF).
  • Considers prophylaxis at recall intervals of 4 months or more.

Discussion:

  • Synthesizes evidence from original human studies on rubber cup dental prophylaxis.
  • Evaluates the efficacy of prophylaxis for caries prevention in children.
  • Assesses the benefit of prophylaxis for gingivitis prevention in the general population.

Key Insights:

  • Dental prophylaxis is not required before PATF for caries prevention in children.
  • Generalizing findings on prophylaxis before PATF to adolescents and adults is not supported.
  • Prophylaxis at 4-month intervals shows no demonstrable benefit for gingivitis prevention.

Outlook:

  • Re-evaluation of standard dental prophylaxis protocols for preventive care.
  • Potential shift towards more targeted or condition-specific preventive interventions.
  • Further research may explore optimal recall intervals and preventive strategies for diverse age groups.
