Oral Cavity01:11

Oral Cavity

1.7K
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...

Assessment of the Mouth01:26

Assessment of the Mouth

485
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.

Tooth Anatomy01:21

Tooth Anatomy

1.2K
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...

Teeth01:15

Teeth

895
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...

Infection01:20

Infection

9.1K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Single Nucleotide Polymorphisms-SNPs01:05

Single Nucleotide Polymorphisms-SNPs

16.8K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Area of Science:

  • Infectious Diseases
  • Public Health
  • Oral Medicine

Background:

  • The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has highlighted the importance of understanding factors influencing disease outcomes.
  • COVID-19 is a highly contagious respiratory illness with significant global health implications.
  • Emerging evidence suggests a connection between oral health and systemic disease severity.

Purpose of the Study:

  • To review current literature on the relationship between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), coronavirus disease 2019 (COVID-19), and oral health.
  • To identify potential benefits of optimal oral hygiene and periodontal health in the context of COVID-19 infection.

Main Methods:

  • A comprehensive literature search was performed using keywords related to SARS-CoV-2, COVID-19, and oral health.
  • Inclusion criteria encompassed clinical studies, case reports, and in vivo studies providing current published evidence.
  • A review methodology was employed to synthesize findings from the selected literature.

Main Results:

  • Survival against SARS-CoV-2 infection may be influenced by periodontal health status.
  • Good oral hygiene practices and regular access to dental care appear to be significant factors.
  • Evidence suggests a potential link between oral health and the prevention and management of COVID-19.

Conclusions:

  • Maintaining optimal oral health, including good periodontal health and hygiene, is potentially beneficial for individuals infected with SARS-CoV-2.
  • Systemic health and cessation of smoking habits may also play a role in mitigating COVID-19 severity.
  • Further research is warranted to fully elucidate the role of oral health in COVID-19 outcomes.
