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

This study reports on treating internal root resorption in lateral incisors caused by dens invaginatus. Root canal treatment with Mineral Trioxide Aggregate (MTA) or gutta-percha showed positive outcomes.

Area of Science:

Endodontics
Dental Morphology

Background:

Internal root resorption (IRR) is a pathological process.
Dens invaginatus (DI), or palatal invagination, can predispose teeth to IRR.
This report focuses on IRR in lateral incisors associated with DI.

Observation:

Three cases of lateral incisors with IRR and DI were treated.
Dens invaginatus type 2 was identified as a potential etiology for IRR in these cases.
Two cases received root canal treatment with a Mineral Trioxide Aggregate (MTA) apical plug, and one received gutta-percha obturation.

Findings:

All treated teeth demonstrated successful management and were followed over time.
The study highlights the potential underestimation of the association between IRR and DI.
Root canal therapy appears effective for managing IRR secondary to DI.

Implications:

The association between internal root resorption and dens invaginatus may be more prevalent than currently recognized.
Further research is warranted to investigate the incidence and management of this condition.
Clinicians should consider dens invaginatus in the differential diagnosis of internal root resorption.
