Background: The Bull terrier breed has been reported in the veterinary literature to sufer frequent dental and skeletal malocclusions. In this retrospective case series, we report skeletal-dental anomalies in a group of 33 Bull terriers
presented for a dental consultation.
Results: Out of 33 dogs examined, 24 cases had full mouth radiography or Cone-beam computed tomography
performed. Eruption and development abnormalities observed were as follows: hypodontia in 54.1% (13/24), eruption changes in 29.2% (7/24), and tooth shape abnormalities in 33.3% (8/24). All dogs presented with some type of
dental or skeletal malocclusion: neutroclusion was the most common (66.7% of the animals), followed by mandibular
mesioclusion (18.8%), maxillo-mandibular asymmetry (9.4%), and mandibular distoclusion (6.3%). Dental abnormalities noted included rotation of mandibular and maxillary premolar teeth, distal displacement of the incisor teeth,
lingual displacement of the mandibular canine teeth, and absence of mandibular premolar and molar teeth. Lingual
displacement of mandibular canine teeth was associated with malocclusion causing trauma (odds ratio 7.1, 95% confdence interval [1.4 to 36.1], p=0.024).
Conclusions: Malocclusions and tooth shape abnormalities were found to be the most frequent fnding in this
group of Bull terriers. Although these fndings cannot be generalized to the global population further studies are
needed to observe the true expression of these anomalies in the general breed population.
