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.

Area of Science:

  • Dentistry
  • Oral Pathology
  • Developmental Biology

Background:

  • Odontomas are the most frequent odontogenic tumors, often viewed as hamartomas.
  • They are typically asymptomatic, discovered incidentally on radiographs.
  • Classified as either complex or compound odontomas.

Purpose of the Study:

  • To present a case report of a complex odontoma.
  • To describe its structural features and defects in enamel, dentin, and cementum.
  • To provide an overview of odontoma etiology.

Main Methods:

  • Radiographic examination for diagnosis.
  • Histopathological analysis of the odontoma's structure.
  • Literature review on odontoma classification and etiology.

Main Results:

  • The complex odontoma displayed sequential development of enamel, dentin, and cementum.
  • No significant bony expansion or signs of infection were noted.
  • The case aligns with the hamartomatous, rather than neoplastic, nature of odontomas.

Conclusions:

  • Complex odontomas present with disorganized dental tissues.
  • Understanding odontoma etiology is crucial for accurate diagnosis and management.
  • Further research into the hamartomatous nature of odontomas is warranted.
