Summary
A canine dental abnormality involving a draining tract led to the discovery of an unerupted supernumerary premolar. Surgical extraction of both the affected molar and the extra tooth was performed.
Area of Science:
- Veterinary Dentistry
- Oral Pathology in Animals
- Comparative Odontology
Background:
- Draining tracts in dogs can indicate complex dental issues.
- Mandibular first molars are prone to pathology.
- Uncommon dental anomalies require thorough investigation.
Purpose of the Study:
- To describe a rare case of canine dental abnormality.
- To detail the diagnostic process for an unerupted supernumerary tooth.
- To report the surgical management of a complex oral condition.
Main Methods:
- Clinical oral examination of a canine patient.
- Anesthetized radiographic evaluation of the mandible.
- Surgical extraction of the affected mandibular first molar and an unerupted supernumerary premolar.
Main Results:
- Two draining tracts were identified associated with the right mandibular first molar.
- Radiographs revealed an unerupted, abnormally positioned, supernumerary premolar tooth.
- Successful extraction of both the diseased molar and the supernumerary tooth with its root was achieved.
Conclusions:
- Supernumerary teeth can cause significant oral pathology, including draining tracts.
- Advanced diagnostics like radiography are crucial for identifying unerupted dental anomalies.
- Surgical intervention is necessary for resolving such complex dental abnormalities in dogs.

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...

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...
