Differential Diagnosis of Dentine Hypersensitivity (DH)
Dentine Hypersensitivity Diagnosis
Dentine hypersensitivity (DH) can often be mistaken for other dental conditions, which makes accurate diagnosis a crucial first step in effective management. The diagnosis of DH is typically made by excluding other causes of dental pain1,2. Since DH mimics many other conditions, a thorough differential diagnosis is essential for successful treatment.
Common Conditions Mimicking DH1,2
Conditions affecting tooth structure
- Cracked tooth1
- Dental caries1
- Root resorption1
- Dental trauma, occlusal trauma2
Conditions related to dental procedures and disease
- Post-operative sensitivity (from restorative, periodontal and bleaching procedures)2
- Defective or fractured restorations1
- Cervical plaque, and gingivitis, periodontal disease.2
Other conditions
- Marginal leakage1,2
- Pulpitis1,2
- Enamel or dentine hypoplasia1,2
Each of these conditions must be carefully excluded before confirming a dentine hypersensitivity diagnosis, as treatment protocols will vary significantly. The use of cold air blast with 3-way syringe, Schiff scale and numerical pain rating scale can be more applicable for effective diagnosis.
“Dentine hypersensitivity diagnosis is highly subjective, relying heavily on patient information to guide conclusions. As a diagnosis of exclusion, it’s often complicated by hidden factors — like tooth cracks — that can remain undetected, prolonging the process of ruling out other issues."
