Tooth Anatomy01:21

Tooth Anatomy

2.6K
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...

Teeth

2.1K
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...

Oral Cavity01:11

Oral Cavity

3.6K
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...

Notch Signaling Pathway03:14

Notch Signaling Pathway

6.8K
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...

Area of Science:

  • Dentistry
  • Oral and Maxillofacial Surgery
  • Radiology

Background:

  • Mandibular premolar impaction is rare.
  • Ectopic tooth placement is even rarer.
  • No prior literature discusses ectopic mandibular premolars in the coronoid process.

Purpose of the Study:

  • To report a case of an impacted ectopic mandibular permanent premolar.
  • To describe its location in the sigmoid notch (incisura mandibulae).
  • To discuss the etiology and treatment options.

Main Methods:

  • Case report presentation.
  • Diagnostic imaging using Cone Beam Computed Tomography (CBCT).

Main Results:

  • An impacted ectopic mandibular permanent premolar was identified in the sigmoid notch region.
  • CBCT imaging provided detailed visualization of the anomaly.

Conclusions:

  • This case highlights a unique presentation of ectopic mandibular premolar impaction.
  • Understanding the etiology and available treatment options is crucial for managing such rare dental findings.
