Dental radiology: ageing changes in permanent teeth of beagle dogs

Abstract: Radiographic interpretation of dental or periodontal disease is dependent in part on an understanding of ageing changes, A progressively ageing colony of healthy beagle dogs (120 to 3759 days) was studied by use of high‐detail radiographs made following the death of the dog. Morphological features whose radiographic appearance was found to be especially age‐dependent were: root canal size, both vertical and horizontal alveolar bone resorption, visualisation of the lamina dura dentis, and detection of hyperceme… Show more

“…In histologic examination of beagles, the dentin wall was seen to be thicker at 6 months of age, and the pulp cavity gradually became narrower up to 9 months of age. This observations corresponded to the radiographic findings by Morgan and Miyabayashi [13].…”

“…Histologic observation is essential to elucidate the apical delta formation in growing dogs, because radiographic evaluation of teeth is known to have limitations [13]. Surgical collection and histologic observation of tooth roots could not therefore be eliminated.…”

“…When looking at the rate of missing teeth by tooth type, a high frequency of first premolars were found to be missing, confirming the findings of Page and Schroeder (1981). This may result from the progression of periodontitis (Morgan and Miyabayashi 1991) or from the type of thecodontal attachment (the collagen fibre attachment supporting the teeth in the alveolar bone) (Dorn 1981, Gaengler 1986). However, a high frequency of incisors was also found to be missing in the present study, which was not the case in the Page and Schroeder (1981) study.…”

“…All of these canid remains have been directly AMS radiocarbon dated (Table 1); all were calibrated using OxCal (v4.1) and the INTCAL09 dataset (Reimer et al, 2009). Ageing of the specimens was done through study of dental eruption patterns and epiphysis fusion (Cahill & Marks, 1982;Evans & Christensen, 1979;Kremenak, 1967;Morgan & Miyabayashi, 1991;Shebestari et al, 1967;Watson et al, 1986). The presence of bacula was used to identify a few canids as males; otherwise, no sexing was attempted.…”
