Quick Reference

An inflammatory benign self-limiting disease of the minor salivary glands, usually caused by a restricted blood supply (ischaemia). It is characterized by necrotic ulceration which is usually painless and may be mistaken clinically as a malignant disease. Predisposing factors include traumatic injury, denture-wearing, smoking, heavy alcohol consumption, and dental local anaesthetic injection. In most cases the hard palate is involved but other sites such as the lower lip, retromolar area, tongue, and parotid glands may also be involved. Treatment is by conservative management such as the use of an antiseptic mouthwash.
