Summary
Excessive strain contributes to equine periodontal disease. This study used finite element analysis (FE) to model equine cheek teeth, revealing age-related increases in tooth intrusion and stress within the periodontal ligament (PDL).
Area of Science:
- Veterinary Dentistry
- Biomechanics
- Computational Modeling
Background:
- Periodontal diseases are common in horses, with excessive tissue strain suspected as a contributing factor.
- Finite element (FE) analysis offers a method to quantify strains and stresses in the periodontium, aiding hypothesis testing.
- Understanding age-related changes in equine dental structures is crucial for assessing periodontal health.
Purpose of the Study:
- To create accurate 3-D finite element models of equine maxillary and mandibular cheek teeth, focusing on the periodontal ligament (PDL).
- To incorporate age-related morphological variations by developing models for three distinct age groups.
- To investigate the biomechanical behavior of the equine PDL during experimental tooth intrusion.
Main Methods:
- Development of detailed 3-D finite element models of equine cheek teeth using anatomical data.
- Construction of age-specific models accounting for morphological changes in teeth and periodontium.
- Simulation of experimental tooth intrusion to analyze biomechanical responses of the periodontal ligament.
Main Results:
- Tooth intrusion increased with age, attributed to age-related alterations in the elastic properties of the periodontal ligament.
- Overall stress levels in the periodontal ligament and surrounding alveolar bone were found to increase with advancing age.
- The study successfully established reliable FE models for analyzing biomechanical effects in the equine periodontium.
Conclusions:
- Finite element analysis provides a valuable tool for understanding biomechanical factors in equine periodontal disease.
- Age-related changes significantly influence the biomechanical properties of the equine periodontal ligament and tooth stability.
- The developed FE models can be used to investigate the etiology of periodontal issues in horses.

01:21Tooth 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.

01:15Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
