Objective—To determine the diagnostic value of 2
intraoral bisecting angle radiographic views in comparison
with periodontal probing for the assessment
of periodontal attachment of the canine teeth in dogs.
Study Population—466 canine teeth from 117 dogs.
Procedure—Periodontal probing measurements
were recorded, and clinical attachment levels (CAL)
were calculated at the mesial, buccal, distal, and lingual
(or palatal) surfaces on each canine tooth.
Occlusal and lateral radiographs of the canine teeth
were obtained. Alveolar margin height (AMH) was
measured at the same 4 surfaces. Values for AMH
and CAL were compared on the basis of tooth surface,
dental arch, and radiographic view.
Results—The AMH at the mesial and distal surfaces of
the mandibular canine teeth was measurable on the
lateral view and was significantly correlated with CAL.
Similar results were found for the mesial and distal surfaces
of the maxillary canine teeth. Buccal and lingual
AMH were measured on the mandibular occlusal radiographic
view, and values were significantly correlated
with CAL, but only the buccal AMH could be assessed
on the occlusal radiographic view of the maxilla with
values that correlated significantly with CAL.
Conclusions and Clinical Relevance—The lateral
radiographic view is suitable for evaluating periodontal
attachment at the mesial and distal surfaces of the
canine teeth in dogs. The occlusal radiographic view is
suitable for assessing buccal surfaces as well as the
lingual surface of mandibular canine teeth but not the
palatal surface of maxillary canine teeth in dogs. (Am J Vet Res 2003;64:255–261)
