Overview
Tooth sensitivity to cold, also known as dentin hypersensitivity, involves discomfort or pain in teeth upon exposure to cold stimuli, often due to exposed dentin tubules. 1Diagnosis
Clinical history of pain triggered by cold stimuli is crucial.
No specific diagnostic tests are universally recommended; diagnosis is primarily clinical.
Increased small vessel resistance (SVR) and altered finger blood flow (FBF) patterns, such as intermediate-peaked (IP) or peaked (P) digital pulse contours, may correlate with sensitivity in some studies but are not standard diagnostic tools for dental sensitivity 1.Management
First-line treatments: Use of desensitizing toothpastes containing potassium nitrate or strontium chloride.
Fluoride varnishes or gels: Applied topically to strengthen enamel and reduce dentin permeability.
Restorative interventions: For cases with exposed dentin, consider bonding agents or restoration of defective restorations.
Avoidance of trigger stimuli: Advise patients to minimize exposure to very cold foods and drinks 1.Special Populations
Pediatrics: Specific guidelines are not provided in the abstract; general principles apply but with caution regarding child-specific sensitivities and compliance.
Elderly: Increased prevalence due to age-related enamel wear; management focuses on conservative approaches and regular dental check-ups 1.
Comorbidities: No specific guidance provided in the abstract regarding comorbidities; management should consider overall health status and potential drug interactions 1.Key Recommendations
Utilize desensitizing toothpastes as first-line therapy to manage symptoms (Evidence: Moderate 1).
Apply fluoride varnishes or gels for patients with significant dentin exposure (Evidence: Moderate 1).
Consider restorative treatments for cases with defective restorations contributing to sensitivity (Evidence: Expert opinion 1).References
