Abstract

The development of veterinary dentistry has substantially improved the ability to diagnose canine and feline dental abnormalities. Consequently, examinations previously performed only on humans are now available for small animals, thus improving the diagnostic quality. This has increased the need for technical qualification of veterinary professionals and increased technological investments. This study evaluated the use of cone beam computed tomography and intraoral radiography as complementary exams for diagnosing dental abnormalities in dogs and cats. Cone beam computed tomography was provided faster image acquisition with high image quality, was associated with low ionizing radiation levels, enabled image editing, and reduced the exam duration. Our results showed that radiography was an effective method for dental radiographic examination with low cost and fast execution times, and can be performed during surgical procedures.

Figure

  • Fig. 1 Cat placed under cone beam computed tomography (CBCT) scanner via a polyvinyl chloride device.

  • Fig. 2 Cone beam CT of a cat's head after trauma. Panoramic view (bidimensional recontruction) showing mandibular (green arrows) and dental (yellow arrow) fractures.

  • Fig. 3 Image of a feline dental resorption lesion. (A) Intraoral radiography (IOR) and (B) CBCT.

  • Fig. 4 Oblique view of a transverse CBCT section showing the mandibular area suitable for dental implantation. The software allowed measurement of the bone that helps determine the choice of implant.

  • Fig. 5 IOR showing dental implant in the mandibular area.
