Summary
Severe external apical root resorption (EARR) is a significant problem, but this study suggests it is linked to patient genetics, not orthodontic treatment variables. Further research into genetic factors is warranted for understanding EARR.
Area of Science:
- Orthodontics
- Genetics
- Dental Research
Background:
- External apical root resorption (EARR) is a known complication of orthodontic treatment.
- While often minor, severe EARR can be clinically significant.
- Existing research frequently examines treatment-related variables for EARR.
Purpose of the Study:
- To investigate the role of commonly cited treatment-related variables in the development of severe EARR.
- To differentiate contributing factors between minor and severe EARR cases.
Main Methods:
- Focused analysis on severe cases of EARR.
- Evaluated frequently cited treatment-related variables.
Main Results:
- Treatment-related variables did not appear to significantly influence the development of severe EARR.
- The distinction between minor and severe EARR is likely due to patient genetic factors.
Conclusions:
- Genetic makeup, rather than orthodontic treatment, is strongly implicated in severe EARR.
- Future research should explore the genetic basis of severe EARR.

01:15Teeth
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...

01:21Tooth 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.
