Tooth Anatomy

501
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

439
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...

Area of Science:

  • Dentistry
  • Dental Materials Science

Background:

  • Intracoronal bleaching, a conservative dental procedure, has been used since the 19th century to improve tooth color.
  • It remains popular for treating internal tooth discoloration due to its minimally invasive nature.
  • Various materials and techniques have evolved to optimize results and mitigate risks.

Purpose of the Study:

  • To review the contemporary applications of intracoronal bleaching.
  • To summarize key aspects relevant to current clinical practice.

Main Methods:

  • Review of historical and current literature on intracoronal bleaching agents and techniques.
  • Analysis of research on the effects of bleaching agents on dental hard tissues.
  • Examination of case reports concerning potential complications.

Main Results:

  • Bleaching agents primarily utilize peroxide-based compounds in diverse formulations.
  • The precise mechanism of bleaching remains under investigation.
  • Concerns regarding invasive root resorption linked to intracoronal bleaching have prompted technique modifications.

Conclusions:

  • Intracoronal bleaching is an established conservative treatment for internal tooth discoloration.
  • Ongoing research focuses on refining techniques to enhance predictability and safety.
  • Addressing risks such as root resorption is crucial for modern intracoronal bleaching protocols.
