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:

Regenerative medicine
Biomaterials science
Oral and maxillofacial surgery

Background:

Maintaining hard and soft tissue dimensions is crucial for regenerative protocols.
Graft material properties significantly influence regenerative outcomes.
Tooth-derived materials are emerging as viable alternatives to synthetic biomaterials for bone augmentation.

Purpose of the Study:

To histomorphometrically evaluate tooth derivative materials used in socket preservation.
To assess the efficacy of autologous demineralized tooth as a bone substitute in alveolar socket preservation (ASP).

Main Methods:

101 histological samples from 96 subjects undergoing ASP with autologous demineralized tooth graft material were analyzed.
Quantified bone volume (BV), residual tooth material (TT), and vital bone (VB).
Sections were divided into subsections for detailed statistical comparison.

Main Results:

No statistically significant difference in vital bone (VB) percentage was observed between maxillary (37.9% ± 21.9%) and mandibular (38.0% ± 22.0%) sites.
Residual tooth material (TT) percentages were similar in maxilla (7.7% ± 12.2%) and mandible (7.0% ± 11.1%).
Defect type and section position did not statistically correlate with histomorphometric results.

Conclusions:

Alveolar socket preservation (ASP) using demineralized autologous tooth-derived biomaterial is a predictable procedure.
This method effectively generates new vital bone.
The new bone has the potential to support dental implant rehabilitation.
