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...
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...
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.
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.
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...
Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

Summary

Adolescent flossing decreases with age, correlating with dental visits and hygiene habits like handwashing. Gender influences perceptions, with males linking flossing to health and females to cleanliness.

Area of Science:

  • Oral hygiene research
  • Adolescent health behaviors
  • Social determinants of health

Background:

  • Dental flossing is a key component of oral hygiene.
  • Understanding adolescent behaviors is crucial for public health interventions.
  • Previous research indicates gender differences in oral hygiene practices.

Purpose of the Study:

  • To investigate the relationship between adolescent flossing behavior and other health, cleanliness, and social behaviors.
  • To explore age-related trends in flossing frequency among adolescents.
  • To identify factors associated with dental flossing in a large adolescent cohort.

Main Methods:

  • Analysis of survey data from 41,142 adolescents (12-16 years old) across 244 secondary schools in England.
  • Anonymous questionnaire assessing flossing frequency, dental attendance, recalled advice, and general cleanliness/social behaviors.

  • Statistical analysis including correlation and factor analysis to examine relationships and gender differences.

    • Main Results:

    • Flossing frequency declined significantly from age 12 to 16.
    • Recent dental attenders and those recalling flossing advice were more likely to floss.
    • Flossing positively correlated with handwashing, bathing frequency, and having opposite-gender friends.
    • A slight association was found between smoking and flossing in specific school years.
    • Factor analysis revealed gender differences: males linked flossing to health, females to cleanliness.

    Conclusions:

    • Adolescent flossing behavior is influenced by age, dental care engagement, and broader hygiene and social factors.
    • Gender significantly shapes the perception and association of flossing with health versus cleanliness.
    • Findings provide insights into adolescent oral hygiene practices and inform targeted public health strategies.
