摘要

The clinical crown length of rabbit teeth has not hcen well documented. The aim of this study was to determine the clinical crown length of incisor and cheek teeth, and the periodontal probing depth in young healthy rabbits without clinical signs of dental disease. Two groups of 20 male rabbits were measured, the first in 2007 and the second in 200iS 2009. The measurements were taken with rabbits under general anesthesia using a periodontal probe. The average crown length (mm) of the mandibular thirdand fourth premolar, and maxillary second premolar teeth was i.l -t - 0.4. 2.6 +/- 0.4. and 1.5 0.4. respectively. The periodontal probing depth for the cheek teeth in the maxilla and the mandible was very similar (0.5 - I.O-mmj. There was a minor difference in the average crown length (mm) of the mandibular (6.4 +/- 0.6) and maxillary (6.1 +/- 0.9) incisor teeth. The periodontal probing depth (mm) was different when comparing maxillary (2.2 +/- 0.4) and mandibular (5.1 +/- 0.8) incisor teeth. The divergence in tooth length in individual rabbits a/id between the two groups was minimal. Measuring the crown length of the rostral cheek and incisor teeth with a periodontal probe is easy to do in the rabbit and should be integrated into the clinical examination. The measurement results of this study can be used as a reference when trimming teeth.
