Hyperaemia
Pronunciation: hy-per-EE-mee-ah
Increased blood flow to the dental pulp, typically in response to irritation or early carious invasion, representing a reversible pre-inflammatory state.
Full Definition
Pulpal hyperaemia describes a condition in which the blood vessels of the dental pulp become engorged due to external stimuli such as thermal changes, chemical irritants, or early carious lesions. It is considered a reversible pulpitis, meaning the pulp can return to normal health if the cause is removed. Editors must recognise that hyperaemia is a clinical diagnosis that distinguishes early pulpal involvement from irreversible conditions such as pulp necrosis. In British English the preferred spelling retains the 'ae' ligature; the American form 'hyperemia' is a common editorial confusable. Documentation of hyperaemia typically appears in clinical notes, treatment plans, and referral letters to indicate urgency of intervention.
Usage
Usage note: Use the 'ae' spelling in British clinical documents. Do not use interchangeably with 'pulpitis', which can denote an irreversible condition; hyperaemia is specifically reversible.
