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.

Veneer

Veneer

Veneer refers to a thin sheet of wood, typically produced to a thickness of about one-eighth of an inch or less. This material is crafted through various methods, the most common being rotary cutting. In this process, a log is mounted into a large lathe and spun against a knife edge, peeling off a continuous strip of wood as the knife penetrates deeper into the rotating log, creating a rotary-cut veneer.
Other veneering techniques include plain-slicing, quarter-slicing, and rift-slicing. These...

Area of Science:

Dental Traumatology
Cell Biology
Biomaterials Science

Background:

Avulsed teeth require immediate and appropriate storage to maintain periodontal ligament (PDL) cell viability.
Current storage media vary in effectiveness and accessibility.
Identifying accessible and effective storage solutions is crucial for improving avulsed tooth outcomes.

Purpose of the Study:

To evaluate the efficacy of egg white as a storage medium for human PDL cells on avulsed teeth.
To compare the viability of PDL cells stored in egg white with other common storage media.

Main Methods:

Human premolar teeth were stored in egg white, milk, Hanks' Balanced Salt Solution (HBSS), or tap water for up to 12 hours.
Periodontal ligament cell viability was assessed using trypan blue staining after trypsinization and collagenase treatment.
Statistical analysis using two-way ANOVA was performed to compare cell viability across different media.

Main Results:

Egg white demonstrated comparable PDL cell viability to HBSS (positive control).
A statistically significant difference was observed in PDL cell viability between egg white and milk (P<0.05) and tap water (P<0.05).
Egg white proved superior to milk and tap water in preserving PDL cell viability.

Conclusions:

Egg white is a viable and effective storage medium for avulsed teeth.
Its primary advantage lies in its widespread availability and low cost.
Egg white presents a practical alternative for emergency tooth avulsion management.
