Tongue01:01

Tongue

1.3K
The human tongue is a fascinating and complex organ, responsible for various essential functions such as swallowing, speech, and taste. It is also subject to various conditions and diseases. In this article, we delve into the anatomy of the tongue, its roles, and some common conditions that can affect it.
Anatomical Position in the Oral Cavity
The tongue is located within the oral cavity, also known as the mouth. It is attached to the floor of the mouth by a fold of mucous membrane called the...

The Tongue and Taste Buds00:49

The Tongue and Taste Buds

37.2K
The surface of the tongue is covered with various small bumps called papillae, which either distribute what has been ingested (filiform papillae) or contain the sensory taste (or gustatory) receptor cells (fungiform, circumvallate, and foliate papillae). Embedded within each taste-related papilla are the taste buds—clusters of 30 to 100 gustatory receptor cells.

Assessment of the Mouth01:26

Assessment of the Mouth

341
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.

Chronic Pharyngitis01:23

Chronic Pharyngitis

4.0K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Tonsillitis I: Introduction

466
Tonsillitis is inflammation of the tonsils, which are two lymphoid tissue masses at the back of the throat. This condition can cause discomfort and irritation in the throat.
Etiology
Three primary contributing factors have been identified.

Acute Pharyngitis

1.3K
Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:

Area of Science:

  • Oral Medicine
  • Infectious Diseases
  • Dermatology

Background:

  • The global spread of coronavirus disease (COVID-19) has led to millions of infections worldwide.
  • While primarily known for respiratory effects, COVID-19 presents with various systemic manifestations.
  • Mucocutaneous symptoms, including oral changes, have been reported in COVID-19 patients.

Observation:

  • This case report focuses on a specific oral manifestation of COVID-19: depapillation of the tongue surface.
  • This condition is colloquially referred to as "COVID tongue."
  • Other observed mucocutaneous symptoms include lesions on the alveolar mucosa, gingiva, buccal mucosa, dysgeusia (altered taste), and dry mouth.

Findings:

  • The study highlights the occurrence of tongue depapillation as a potential symptom associated with COVID-19 infection.
  • The direct causal relationship between COVID-19 and the observed systemic manifestations, including oral changes, is not yet definitively established.
  • The etiology of these systemic infections in the context of COVID-19 requires further investigation.

Implications:

  • Understanding the full spectrum of COVID-19 symptoms, including oral manifestations, is crucial for comprehensive patient care.
  • The findings underscore the need for continued research into the long-term effects and direct etiological links of COVID-19.
  • Further studies will help in accurately diagnosing and managing patients experiencing systemic and mucocutaneous symptoms related to COVID-19.
