Metabolic bone disease in wild collared doves (Streptopelia decaocto)
The records of 666 casualty collared doves examined at a wildlife hospital in south-west England over a period of five years were reviewed. Signs of metabolic bone disease were recorded in 51-2 per cent of the juvenile birds but in only 9-6 per cent of the adults. The incidence of the condition was highest between December and February and decreased almost to zero between June and August. Histological lesions in 11 of the juvenile doves were consistent with vitamin D deficiency, possibly as a result of inadequate exposure to UVB light during the short winter days
Detecting chronic apical periodontitis for improved endodontic success
Endodontic treatments are frequently carried out in daily
clinical practice. The presence or absence of a periapical
radiolucency, assessed using intraoral radiographs, is one
of the criteria used to determine endodontic success. When
such a lesion is present around the apex of a tooth, the
condition is known as chronic apical periodontitis. While
this is common around root treated teeth, it can also be
associated with otherwise healthy teeth. In both instances, it
represents an inflammatory response to bacteria or irritants
in the periapical space, and results in bone loss and areas
of reduced density, which can then form apical granulomas
or cysts. The literature has shown that periapical lesions
can go undetected, due to the two-dimensional limitations
of periapical radiographs. These “hidden” lesions can
compromise the longevity of the tooth. Considering that
apical periodontitis can be far more accurately detected
and diagnosed on cone beam computed tomography, it
has been recommended by several authors that endodontic
treatment outcomes ideally should be evaluated using this
imaging modality, whenever possible.https://www.sada.co.za/the-sadjam2018Prosthodontic
