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...

Area of Science:

Dentistry
Oral Pathology

Background:

Enamel pearls are typically small, globular enamel formations found on maxillary molars.
Their etiology and pathophysiology are not fully understood.

Observation:

A 42-year-old woman presented with severe toothache and a deep periodontal pocket on her left mandibular first molar.
Radiographic and cone-beam computed tomography (CBCT) imaging revealed an 8mm long, prolate spheroid-shaped enamel pearl in the furcation area.

Findings:

The enamel pearl measured 1.8mm wide and 8mm long, an atypical morphology and location.
CBCT imaging proved effective in visualizing the unusual enamel pearl structure.

Implications:

This case expands the known morphological spectrum of enamel pearls.
Highlights the utility of advanced imaging like CBCT in diagnosing rare dental anomalies.
