Tooth Anatomy01:21

Tooth Anatomy

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 grinding food.
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...
Teeth01:15

Teeth

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 and...
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.
Tonsillitis II: Management01:26

Tonsillitis II: Management

This lesson will focus on the different treatment options for managing tonsillitis, which typically depend on the cause and severity.
Endoscopic Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Summary
This summary is machine-generated.

A patient developed cervicofacial swelling after dental work, diagnosed as cervicofacial mediastinal emphysema due to air entrapment. Antibiotic treatment resolved the condition, allowing for symptom-free discharge.

Area of Science:

  • Medicine
  • Radiology
  • Otolaryngology

Background:

  • Cervicofacial swelling can arise from various causes.
  • Professional tooth cleaning is a common dental procedure.
  • Mediastinal emphysema involves air in the chest cavity.

Observation:

  • A 52-year-old presented with indolent cervicofacial swelling post-dental cleaning.
  • Computed tomography revealed air extending from the head to the mediastinum.

Findings:

  • Diagnosis of cervicofacial mediastinal emphysema was confirmed.
  • The condition was successfully treated with antibiotics.

Implications:

  • This case highlights a rare complication of dental procedures.
  • Prompt diagnosis and treatment are crucial for managing emphysema.
  • Understanding air migration pathways is important in cervicofacial emergencies.
