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:

Veterinary Surgery
Equine Dentistry
Computer-Assisted Surgery

Background:

Cheek tooth impaction and related pathologies are common in equids.
Traditional surgical approaches for equine cheek tooth extraction can be challenging.
Computer-assisted surgery (CAS) offers potential for enhanced precision in complex dental procedures.

Purpose of the Study:

To evaluate the efficacy and outcomes of using CAS for cheek tooth repulsion in equids.
To assess the safety and accuracy of navigated exodontia in equine dental surgery.

Main Methods:

A retrospective case series involving 16 equids undergoing cheek tooth repulsion.
Surgery performed under general anesthesia utilizing CAS for real-time intraoperative guidance.
Detailed recording of surgical approaches, complications, and outcomes.

Main Results:

Successful navigated repulsion of cheek teeth in 15 out of 16 subjects.
One case required additional intraoral sectioning, and another involved a nasal approach with temporary tracheotomy.
Six subjects required revision surgery for fragment removal.
Overall successful outcome in 15 subjects; one subject was euthanized due to unrelated squamous cell carcinoma.

Conclusions:

Computer-assisted surgery provides controlled and accurate surgical access for equine cheek tooth exodontia.
CAS is a valuable tool for improving precision and outcomes in complex equine dental extractions.
Navigated repulsion can be safely employed for challenging cheek tooth removal in equids.
