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 and...

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.

Most cases of maxillary incisor root resorption from ectopic canine treatment showed no progression long-term. Teeth with resorption had a good prognosis, but severe cases may require extraction.

Orthodontics
Dental Radiology
Periodontology

Background:

Ectopic maxillary canines can cause incisor root resorption.
Long-term effects of this resorption are not well-documented.

Purpose of the Study:

To evaluate long-term clinical and radiographic outcomes of maxillary incisor root resorption.
To assess the prognosis of teeth with resorption after ectopic canine treatment.

Main Methods:

Retrospective study of 55 incisors in 38 subjects treated for ectopic canines.
Long-term follow-up (13-28 years) with radiography and clinical examination.
Correlation of resorption severity with clinical characteristics.

Main Results:

Four incisors were lost due to resorption.
Most resorptive lesions (26/36) were stable; some improved (3/36) or worsened (7/36).
No significant clinical differences between resorbed and sound incisors were found.

Conclusions:

Maxillary incisor root resorption from ectopic canines generally has a good long-term prognosis.
Teeth with root resorption typically remain asymptomatic.
Extraction of severely resorbed lateral incisors may be necessary in favor of healthy premolars.
