Teeth

310
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...

Summary
This summary is machine-generated.

Periapical cysts in dogs originate from non-vital teeth without pulp exposure. Surgical removal of the cyst and affected tooth successfully resolved clinical signs in affected dogs.

Area of Science:

  • Veterinary Pathology
  • Comparative Dentistry
  • Oral Surgery

Background:

  • Periapical cysts are inflammatory jaw lesions that can affect dogs.
  • Accurate diagnosis is crucial for differentiating these cysts from other odontogenic tumors and cysts.
  • Understanding their clinical, imaging, and histological features aids in effective treatment.

Purpose of the Study:

  • To characterize the clinical, diagnostic imaging, and histological features of periapical cysts in dogs.
  • To describe the treatment outcomes for periapical cysts in canine patients.

Main Methods:

  • Retrospective review of medical records from client-owned dogs diagnosed with periapical cysts.
  • Inclusion criteria focused on dogs with surgical biopsy specimens of cavitary lesions diagnosed as odontogenic cysts.
  • Analysis included clinical presentation, diagnostic imaging, histological findings, and treatment results.

Main Results:

  • Ten dogs were included, aged 2.5-12.1 years, with periapical cysts affecting the incisive bone and/or maxilla.
  • Common clinical signs included oral/gingival swelling; one dog presented with dyspnea.
  • Cysts originated from non-vital teeth with structural defects (wear/fracture without pulp exposure) or intrinsic staining; surgical extraction and enucleation led to resolution.

Conclusions:

  • Periapical cysts in dogs are consistently associated with non-vital teeth, even without obvious pulp exposure.
  • Comprehensive evaluation of clinical, imaging, and histological data is essential for accurate diagnosis.
  • Surgical management involving tooth extraction and cyst enucleation is an effective treatment strategy.
