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...

Summary

Micro-computed tomography (micro-CT) offers a non-destructive method for diagnosing odontomas, the most common benign odontogenic tumors. This advanced imaging technique provides detailed 3D analysis comparable to traditional histopathology.

Area of Science:

Oral and Maxillofacial Radiology
Dental Pathology
Biomedical Imaging

Background:

Odontomas are the most frequent benign tumors of odontogenic origin, often asymptomatic and detected via routine radiography.
Complex odontomas can be radiographically mistaken for other calcified bone lesions, necessitating accurate diagnostic methods.
Histopathologic evaluation is crucial for definitive diagnosis but involves sample destruction.

Purpose of the Study:

To present a case of odontoma diagnosed using cone-beam computed tomography (CBCT) and micro-computed tomography (micro-CT).
To evaluate the efficacy of micro-CT as a diagnostic tool for odontomas compared to histopathology.
To highlight the advantages of micro-CT in analyzing dental pathologies.

Main Methods:

A 26-year-old male patient with an odontoma observed on panoramic radiographs and CBCT.
Surgical excision of the odontoma and impacted third molar using a modified Neumann approach.
Post-surgical analysis of the excised sample using both conventional histopathology and micro-CT.

Main Results:

Micro-CT provided high-resolution three-dimensional analysis of the odontoma sample.
The diagnostic assessment by micro-CT was comparable to histopathology.
Micro-CT allowed for sample evaluation without causing destruction, unlike histopathology.

Conclusions:

Micro-CT is a promising non-destructive imaging technology for the diagnosis of odontomas.
It offers comparable diagnostic accuracy to histopathology with the advantage of sample preservation.
Further development of micro-CT could establish it as a valuable future diagnostic tool in dentistry and oral pathology research.
