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...

Teeth

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...

Summary

Impacted maxillary canines frequently cause root resorption (RR) in adjacent teeth, particularly lateral incisors. Increased canine angulation significantly correlates with severe RR, detectable via CBCT imaging.

Background:

Impacted maxillary canines can lead to root resorption (RR) in adjacent teeth.
Cone-beam computed tomography (CBCT) aids in identifying features of impacted canines and associated pathologies.

Purpose of the Study:

To determine the prevalence, location, and severity of root resorption caused by impacted maxillary canines.
To investigate the association between impacted canine features and root resorption on CBCT.

Main Methods:

CBCT images of 89 subjects (108 impacted canines) with no prior orthodontic treatment were analyzed.
Parameters assessed included canine location, RR levels, occlusal/midline distances, and angulations.
Logistic regression evaluated the association between RR and measured canine parameters.

Main Results:

60.2% of impacted canines caused root resorption in adjacent teeth; lateral incisors were most affected (34.3%).
Higher angulation of impacted canines correlated with more severe root resorption (p < 0.05).
Root resorption was more frequent in female subjects and most common at the apical third of the root.

Conclusions:

CBCT is sensitive for diagnosing root resorption location and severity related to impacted canines.
A significant association exists between the linear and angular features of impacted maxillary canines and root resorption.
