The Oral Microbiota01:27

The Oral Microbiota

87
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...

Oral Cavity01:11

Oral Cavity

3.7K
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

2.2K
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...

Microbial Classification System01:24

Microbial Classification System

1.8K
Classification is the process of organizing organisms into hierarchically inclusive groups based on their phenotypic similarities or evolutionary relationships. A species comprises one or more strains, and closely related species are grouped into genera. Genera are further classified into families, families into orders, orders into classes, and so forth, up to the domain level, which is the broadest taxonomic rank derived from a combination of phenotypic and genotypic data.The nomenclature of...

Tooth Anatomy01:21

Tooth Anatomy

2.7K
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...

Assessment of the Mouth01:26

Assessment of the Mouth

1.6K
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.

    Summary
    This summary is machine-generated.

    A new classification system for halitosis (bad breath) has been developed, moving beyond subjective descriptions. This framework categorizes bad breath causes for better clinical management.

    Area of Science:

    • Dentistry
    • Otolaryngology
    • Gastroenterology
    • Internal Medicine

    Background:

    • Current definitions and classifications of halitosis lack universal acceptance and standardization.
    • Existing terminology and classification systems for halitosis are inconsistent.
    • There is a need for a precise, standardized definition and classification of halitosis.

    Purpose of the Study:

    • To propose a novel, objective definition for halitosis.
    • To establish a new classification system for halitosis.
    • To revise existing terminology and exclude temporary exogenous odors.

    Main Methods:

    • Development of a new definition excluding subjective descriptions and temporary exogenous odors.
    • Proposal of a new etiological classification for pathologic halitosis.
    • Revision of previously used terms in halitosis literature.

    Main Results:

    • A new classification divides pathologic halitosis into five types: Type 1 (oral), Type 2 (airway), Type 3 (gastroesophageal), Type 4 (blood-borne), and Type 5 (subjective).
    • Physiologic odor (Type 0) is recognized as a baseline in healthy individuals.
    • Halitosis complaints can be a combination of multiple types, superimposed on physiologic odor.

    Conclusions:

    • The proposed system accommodates multiple diagnoses, reflecting the multifactorial nature of halitosis.
    • This classification provides a more accurate model for understanding halitosis.
    • It establishes an efficient and logical foundation for the clinical management of halitosis.
