The diagnosis of DH may be challenging. It is a diagnosis of exclusion, reached once all other possible explanations for the pain have been ruled out. A thorough patient history and clinical examination are required. The examination includes a pain provocation test by blasting air from a dental instrument onto the sensitive area, or gentle scratching with a dental probe. If a negative result for the pain provocation test occurs, no treatment for<unk> al<unk>  is indicated and another diagnosis should be sought, such as other causes of orofacial pain. Inflammation of the dental pulp, termed pulpitis, produces true<unk>  of the nerves in the dental pulp. Pulpitis is classified as irreversible when pulpal inflammation will irreversibly progress to pulpal necrosis due to compression of the venous microcirculation and tissue ischemia, and reversible when the pulp is still capable of returning to a healthy, non-inflamed state, although usually dental treatment is required for this. Irreversible pulpitis is readily distinguishable from DH. There is poorly localized, severe pain which is aggravated by thermal stimuli, and which continues after the stimulus is removed. There also is typically spontaneous pain without any stimulus. Reversible pulpitis may not be so readily distinguishable from DH, however usually there will be some obvious sign such as a carious cavity, crack, etc. which indicates pulpitis. In contrast to pulpitis, the pain of DH is short and sharp.
