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.

Summary

Small diameter repulsion pins offer an effective method for equine cheek tooth extraction when oral extraction fails. This technique resulted in a 25% complication rate, comparable to other repulsion methods.

Area of Science:

  • Veterinary Surgery
  • Equine Dentistry

Background:

  • Equine dental repulsion has historically high complication rates (up to 80%).
  • Recent advancements in repulsion techniques aim to improve outcomes.

Purpose of the Study:

  • To evaluate the efficacy and complication rates of using small diameter repulsion pins for equine cheek tooth extraction.
  • To describe the outcomes in 20 cases requiring repulsion after failed oral extraction.

Main Methods:

  • A retrospective case series of 20 horses undergoing cheek tooth repulsion between 2014 and 2023.
  • Small diameter (3-5 mm) repulsion pins were used, with intra-operative radiographs guiding placement.
  • Horses were assessed 4-6 weeks post-operatively.

Main Results:

  • All 20 cases (15 maxillary, 5 mandibular) were successfully repulsed.
  • The majority of teeth (75%) had pre-existing fractures.
  • Overall complication rate was 25%, including minor intra-operative and short/long-term issues.

Conclusions:

  • Small diameter repulsion pins provide an effective alternative for equine cheek tooth extraction when oral methods fail.
  • The complication rate of 25% is comparable to established repulsion techniques and trans-buccal screw extraction.
  • This method offers a viable option with manageable complication rates.
