Increased sensitivity to stimuli, specifically hot and cold, is a common symptom of<unk> . A prolonged throbbing pain may be associated with the disease. However,<unk>  can also occur without any pain. Reversible<unk>  is characterised by intermittent, brief discomfort initiated by a hot, cold or sweet stimulus. The pain evoked is of short duration and there is no lingering or spontaneous pain. The pain ceases within a short period after removal of the stimulus. With a reversible<unk> , sleep is usually not affected and no analgesics are necessary. Usually, no atypical change is evident on the radiograph. Pulp vitality tests are positive and it is possible to preserve a healthy vital pulp. Irreversible<unk> , in contrast, is characterised by a constant severe pain that arises without provocation. Characteristics may include sharp pain upon thermal stimulus, lingering thermal pain, spontaneity, and referred pain. Sometimes, the pain may be accentuated by postural changes such as lying down or bending over. If a stimulus is applied, the pain persists for minutes or hours after removal of the stimulus. These indicate that the vital inflamed pulp is not capable of healing and it is often indicated for the pulp to be removed as it is too damaged. Sleep may be disturbed and over-the-counter painkillers are often taken in an attempt to provide relief, but are usually ineffective.
