    Metabolic bone disease in wild collared doves (Streptopelia decaocto)

    No full text
    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
