The Oral Microbiota01:27

The Oral Microbiota

41
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...

Assessment of the Mouth01:26

Assessment of the Mouth

1.5K
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.

Teeth01:15

Teeth

2.3K
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...

Methods of Classification and Identification01:28

Methods of Classification and Identification

1.9K
Bacterial identification relies on a diverse array of techniques to classify and understand microorganisms, each tailored to uncover specific characteristics. Traditional morphological approaches, while still valuable, are limited for closely related or structurally simple organisms. Modern methods integrate biochemical, serological, genetic, and advanced molecular tools to achieve greater accuracy.Morphological and Biochemical TechniquesMorphological characteristics, such as cell shape and...

Oral Cavity01:11

Oral Cavity

4.0K
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...

Tooth Anatomy01:21

Tooth Anatomy

2.9K
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...

Area of Science:

  • Oral Medicine
  • Dentistry
  • Otolaryngology

Background:

  • Misclassification of halitosis leads to ineffective treatments.
  • A standardized approach to halitosis diagnosis is needed.
  • Understanding the diverse etiologies of halitosis is crucial for patient care.

Purpose of the Study:

  • To present a clinical classification system for halitosis.
  • To organize halitosis into distinct types based on etiology and clinical presentation.
  • To propose a diagnostic workflow for differentiating halitosis causes.

Main Methods:

  • Development of a clinical classification system for halitosis.
  • Categorization of halitosis into intraoral, extraoral, and perceptual types.
  • Proposal of a diagnostic workflow for clinical application.

Main Results:

  • Halitosis is classified into eight types: tongue biofilm, periodontal disease, peri-implant disease, xerostomia-associated halitosis, airway-related conditions, metabolic/systemic disorders, pseudohalitosis, and halitophobia.
  • Intraoral causes are identified as significant contributors.
  • Extraoral and perceptual conditions are also delineated.

Conclusions:

  • The proposed classification system provides a framework for understanding halitosis etiology.
  • The diagnostic workflow can assist clinicians in identifying the specific cause of halitosis.
  • Accurate classification is essential for targeted and effective halitosis treatment.
