Maxillary Dentigerous Cyst with Double Wolf Teeth in a 3-Year-Old Quarter Horse Mare.

This study presents a unique case of a horse with a dental cyst surrounding a supernumerary (extra) tooth and discusses the surgical removal and possible causes of this phenomenon.

Understanding the Research

• The focus of this study is an abnormal dental condition in a 3-year-old Quarter Horse mare, specifically an occurrence of dentigerous cyst, which is a type of dental cyst that encloses a tooth. This condition is unusual and points to an obscure embryological development process.
• Dentigerous cysts contain dental material and their level of development varies. These cysts are not commonly seen in horses, making this case unique.
• Ectopic teeth, or teeth growing in places where teeth do not typically develop, commonly associate with dentigerous cysts in horses and create significant clinical issues. However, in this study, there was an existence of a supernumerary tooth, or an extra tooth, which are generally considered to have a limited impact.

The Case of the Supernumerary Tooth and the Dentigerous Cyst

• In this instance, the horse had an extra first premolar (named Triadan 105). What set this case apart from others in existing scientific literature was the formation of a cystic structure around this extra tooth which is unusual.
• The researchers/detail the surgical procedure to remove this dental cyst and discuss potential reasons for the cyst’s development.

Implications of the Research

• This specific case throws light on a new understanding that the development of a cystic structure may not be exclusive to so-called typical polyodontias (conditions involving an irregular number of teeth), but may also occur in cases of supernumerary teeth.
• Therefore, the study prompts further investigation into the correlation between extra teeth development and the formation of dental cysts to better understand and treat such situations in horses.
