Tooth Anatomy

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.

Summary

This summary is machine-generated.

Orthodontists are likely to alter clear aligner treatment plans when provided with 3D crown, root, and bone imaging. This advanced view significantly impacts practitioner decisions and satisfaction with treatment outcomes.

Area of Science:

Orthodontics
Dental Imaging
Artificial Intelligence in Medicine

Background:

Clear aligner technology utilizes machine learning for orthodontic treatment.
3D imaging of crown, root, and bone is proposed for accurate diagnosis and improved outcomes in complex adult cases.

Purpose of the Study:

To determine if orthodontists modify treatment plans with 3D crown, root, and bone views.
To assess changes in practitioner satisfaction with treatment outcomes after viewing 3D crown, root, and bone data.

Main Methods:

An online survey was distributed to orthodontists.
Respondents reviewed patient videos with crown-only and crown, root, and bone views generated by AI software.
Statistical analysis evaluated the impact of 3D views on treatment planning and outcome satisfaction.

Main Results:

70 orthodontists participated, showing significant differences in responses between the two viewing methods.
33%-43% of practitioners changed their treatment plan sentiment (P <0.001).
Average satisfaction ratings shifted by 10.6-21.0 points, with both increases and decreases observed (P <0.001).

Conclusions:

3D crown, root, and bone imaging influences orthodontists' clear aligner treatment plan decisions.
Confirmation of dehiscence and fenestrations via root and bone views can decrease practitioner satisfaction, even with initial positive assessments.
