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.

Oral Cavity

Oral Cavity

The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Teeth

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...

Summary

Odontogenic myxoma, a benign jaw tumor, can cause pain and tooth issues. Surgical resection offers a good prognosis, with this case showing no recurrence after one year.

Area of Science:

Dentistry
Oral and Maxillofacial Surgery
Oncology

Background:

Odontogenic myxoma is a recurrent, benign neoplasm.
It can cause pain, tooth mobility, and dysesthesia.
Malignant transformation is rare, with good prognosis after enucleation.

Observation:

A 53-year-old woman presented with a growing mass in the right geniana region.
Imaging revealed a poorly delimited hypodense central lesion.
Histopathology confirmed Odontogenic myxoma.

Findings:

The lesion was located in the right upper jaw, posing a unique challenge.
Surgical en bloc resection with safety margins was performed.
A one-year follow-up showed no complications or recurrence.
