Teeth

431
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...

Tooth Anatomy

478
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...

Summary
This summary is machine-generated.

Orthodontic aligners are evolving, with rotational and vertical movements posing challenges. While pain perception is low initially, complex cases require more time, and potential risks like root resorption and white spots exist.

Area of Science:

  • Orthodontics
  • Dental Materials Science
  • Biomaterials

Background:

  • Orthodontic aligners lack robust scientific evidence, relying heavily on clinical experience.
  • Continuous evolution of aligner technology necessitates updated manufacturing and treatment protocols.
  • Need for evidence regarding attachments, skeletal anchorage, and material safety.

Purpose of the Study:

  • To synthesize existing evidence on the efficacy and safety of orthodontic aligners.
  • To identify challenges and limitations associated with aligner treatments.
  • To highlight areas requiring further scientific investigation and clinical trials.

Main Methods:

  • Systematic review of evidence from six major electronic databases.
  • Information presented in a question-and-answer format for clarity.
  • Comprehensive search across CINAHL, MEDLINE, EMBASE, Psych Info, Cochrane Library, and Joanna Briggs Library.

Main Results:

  • Aligners exhibit varying difficulty levels for tooth movements; rotational and vertical movements are most challenging.
  • Pain perception is lower at treatment initiation, but complex cases with speech changes require longer duration.
  • Aligners do not prevent root resorption, but may reduce incidence/severity; risks include white spots, caries, and periodontal disease.
  • Bisphenol-A release is possible, and environmental impact of aligner disposal needs addressing.

Conclusions:

  • Significant challenges exist in achieving complex tooth movements with current aligner technology.
  • While offering some benefits, aligners present risks that require careful patient management.
  • There is a critical need for high-quality randomized controlled trials to guide aligner development and application.
