Osteonecrosis of the jaw (ONJ) is most commonly related to medications such as anti-resorptives and anti-angiogenics or head and neck radiotherapy. However, in addition to these, alternative causes of ONJ have also been reported including; infection, chemical toxicity, trauma and vascular ischaemia, but this list is not exhaustive. It is well accepted that cemento-osseous dysplasia (COD) can increase the risk of infection, poor healing and osteomyelitis due to the reduced vascularity. However, necrotic and exposed COD has not been widely reported. This case report describes a patient with COD-related necrosis in the anterior mandible and hence provides an additional member to the ever growing list of potential predisposing factors for jaw necrosis CPD/Clinical Relevance: Cemento-osseous dysplasia is a well recognized and benign condition commonly diagnosed from radiographs. The condition carries an increased risk of osteomyelitis and slow healing following oral surgery and, at its extreme, can cause osteonecrosis of the jaw, which remains an important condition of which the general dental practitioner (GDP) should be aware.

Diseases of the salivary glands are uncommon and patients present to a number of specialties. The result is that experience is thinly spread across clinical specialities. A dedicated salivary gland clinic was set up at Guy's Hospital London fifteen years ago. The profile of patients referred to the centre over the last ten years was analysed and changes in management mapped over time with respect to methods of investigation and treatment. Gland removal, which was previously the treatment of choice for most benign salivary gland diseases has been replaced by gland sparing procedures which have rendered gland excision to a minor role in management. Salivary gland surgery-related morbidity has been markedly reduced.
