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 Tongue and Taste Buds00:49

The Tongue and Taste Buds

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.
Tongue01:01

Tongue

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...
Taste Buds and Receptors01:20

Taste Buds and Receptors

Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

Endocarditis II: Clinical Features of Infective Endocarditis

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
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...

Summary

Tongue lesions are common, particularly reactive and benign tumors in males. Malignant neoplasms, though less frequent, increase with age, highlighting the need for vigilance in older populations.

Area of Science:

  • Oral Pathology
  • Epidemiology
  • Oncology

Background:

  • Tongue lesions are a significant component of oral mucosal lesions.
  • Prevalence of tongue lesions varies globally.
  • Understanding local prevalence is crucial for public health.

Purpose of the Study:

  • To determine the prevalence of tongue lesions in a Brazilian population.
  • To categorize tongue lesions by type: malignant tumors, benign tumors, reactive lesions, and other lesions.

Main Methods:

  • A collaborative study involving 5 anatomic pathology services in Brazil.
  • Analysis of 6231 oral biopsy specimens.
  • Classification of tongue lesions into four distinct groups.

Main Results:

  • Tongue lesions accounted for 12.2% of all oral biopsies (760 cases).
  • Reactive lesions (44.6%) and benign tumors (27.9%) were most common.
  • Malignant tumors represented 18.6%, with prevalence increasing with age.

Conclusions:

  • Tongue diseases are more prevalent in males.
  • Reactive lesions and benign neoplasms are the most frequent diagnoses.
  • A significant proportion of tongue lesions are malignant, particularly in older individuals.
