Association of Two Desensitizing Protocols to Control Dentinal Hypersensitivity in Non-carious Lesions

Association of Two Desensitizing Protocols to Control Dentinal Hypersensitivity in Non-carious Lesions: A Randomized, Double-blind Clinical Trial.

This randomized, double-blind clinical trial evaluated the effect of photobimodulation associated with 8% strontium acetate in the treatment of dentin hypersensitivity in non-carious lesions and analyzed the risk factors with the patient's quality of life.

• Age between 18 to 50 years
• Good general health
• Dental sensitivity with response ≥ 4 on the 10 cm long visual analog scale (EVA)
• Presence of at least two hypersensitive teeth with a depth of up to 1 mm (measured with a millimeter probe)
• Exposed root surface caused by abrasion, erosion or gum recession

Exclusion Criteria:

• Volunteers using analgesic medication
• Presence of teeth with evidence of carious lesions, pulpitis, defective restorations and moderate or severe periodontal disease
• Patients who had undergone any whitening therapy or professional or homemade desensitizer in the last six months
