Description
Estimated cost for Pulp vitality testing at general public hospitals in China is about ¥15-40, and at Grade 3A hospitals about ¥20-50, varying by hospital tier and region.
Main Uses
To assess the sensory and vascular integrity of the dental pulp; differentiate between reversible and irreversible pulpitis; confirm pulp necrosis prior to root canal treatment; evaluate pulp status after dental trauma or restorative procedures; aid in diagnosing symptomatic vs. asymptomatic apical periodontitis; support differential diagnosis of orofacial pain of dental origin.
Normal Range
No numerical values or quantitative 'range' exists for pulp vitality testing; it is a qualitative, binary (vital/non-vital) assessment. A normal response is defined as a transient, mild-to-moderate, reproducible sensation (e.g., sharp, brief pain) upon thermal (cold <10°C or heat >60°C) or electrical stimulation, with prompt cessation after stimulus removal. Absence of response after adequate stimulation is interpreted as non-vital pulp.
Low Values - Possible Causes
Pulp necrosis, irreversible pulpitis with nerve exhaustion, sclerosed or calcified pulp canals, recent dental trauma causing neurovascular compromise, advanced pulpal fibrosis or atrophy due to aging or chronic inflammation
High Values - Possible Causes
Hyperalgesia in reversible pulpitis, dentin hypersensitivity unrelated to pulp pathology, recent pulp exposure without necrosis, exaggerated neural response due to anxiety or central sensitization, incomplete anesthesia during testing leading to misinterpreted heightened perception
