Hyperaemia
Pronunciation: hy-per-EE-mee-ah
Increased blood flow or congestion within the dental pulp, representing an early reversible inflammatory response.
Full Definition
Pulpal hyperaemia is considered a transitional state between a healthy pulp and irreversible pulpitis, characterised by vascular dilation and increased blood flow in response to a stimulus such as caries, trauma, or thermal irritation. Clinically it presents as sensitivity that resolves promptly after stimulus removal. Editors must note the distinction between 'hyperaemia' (the physiological vascular state) and 'pulpitis' (frank inflammation with cellular infiltrate). In British English the preferred spelling is 'hyperaemia'; American English uses 'hyperemia.' Manuscripts should be consistent in their choice of spelling convention throughout.
Usage
Usage note: Adopt either British ('hyperaemia') or American ('hyperemia') spelling consistently throughout a document. Flag inconsistencies for author clarification.
