Micro-computed tomography of the head and dentition in cadavers of clinically normal rabbits
2012
Objective: To describe the anatomic features of dentition and surrounding structures of the head in rabbits assessed by use of a newly developed micro-computed tomography (CT) device. Sample: Cadavers of 7 clinically normal adult Dendermonde White domestic rabbits raised for human consumption. Procedures: The rabbits were slaughtered in a slaughterhouse, flayed, and decapitated; the rabbit heads were frozen for micro-CT examination. Transverse images were obtained from the nares to the occipital condyles with a custom-designed micro-CT scanner built at the Ghent University Centre for X-ray Tomography. Scan settings were chosen to highlight bony structures on the basis of the designers' experience. The micro-CT images were reviewed, and all recognizable anatomic features were labeled. Afterward, micro-CT images were used to create 3-D reconstructions by use of a custom-developed reconstruction package and 3-D rendering with dedicated software. Results: Microstructures of the bones and teeth were clearly visible on micro-CT images. Conversely, soft tissue contrast was relatively poor on these images. Conclusions and Clinical Relevance: Micro-CT appeared to be a promising technique for appropriate diagnosis of dental disease in rabbits. Further research is needed to determine the clinical applications of micro-CT imaging.
