Summary
A displaced deciduous canine tooth root was found within the developing permanent canine in a dog. This rare complication can lead to permanent tooth non-vitality and requires consideration during extractions.
Area of Science:
- Veterinary Dentistry
- Comparative Odontology
- Canine Oral Surgery
Background:
- Persistent deciduous teeth can complicate the eruption of permanent teeth in young dogs.
- Canine tooth extraction is a common procedure, but potential complications require careful consideration.
Observation:
- A 23-month-old Cavalier King Charles Spaniel presented with persistent deciduous maxillary canine teeth.
- Following extraction, the permanent left maxillary canine tooth became non-vital with arrested development.
- Radiographs revealed a radio-opaque, dentine-like structure within the permanent tooth's pulp canal.
Findings:
- A root fragment from the deciduous left maxillary canine tooth was displaced into the pulp chamber of the developing permanent left maxillary canine tooth.
- This internal displacement was confirmed as the cause of the permanent tooth's non-vitality and developmental arrest.
Implications:
- Veterinarians should be aware of the potential for deciduous tooth root displacement during extraction.
- This case highlights an unusual complication that can impact permanent tooth development and vitality.
- Careful radiographic assessment and surgical technique are crucial during deciduous tooth extraction procedures.

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...
