Treating dentin hypersensitivity: therapeutic choices made by dentists of the northwest PRECEDENT network

Abstract

Background: Methods used by dental practitioners to diagnose and treat dentin hypersensitivity are not well documented. The authors conducted a survey of dentists in the Northwest Practice-based REsearch Collaborative in Evidence-based DENTistry (PRECEDENT) to ascertain the treatment methods they used. Methods. Via an Internet survey, the authors collected data regarding methods used for diagnosis and treatment of dentin hypersensitivity from 209 Northwest PRECEDENT dentists.

Results: The PRECEDENT dentists indicated that they most often used fluoride varnishes and gels, advice regarding toothbrushing and diet, bonding agents, restorative materials and glutaraldehyde/2-hydroxyethyl methacrylate (HEMA) to treat dentin hypersensitivity. They reported that the most successful treatments were fluorides, glutaraldehyde/HEMA, bonding agents, potassium nitrates and restorative treatments; they considered observation, advice regarding toothbrushing and diet and laser therapy to be the least successful. Dentists listed fluorides, calcium phosphates, glutaraldehyde/HEMA and bonding agents as the treatments most desirable for inclusion in a future randomized clinical trial of dental hypersensitivity treatments.

Conclusions: Dentists rely on patients to assess the severity of dentin hypersensitivity. Modalities for the diagnosis and treatment of hypersensitivity are diverse. Methods used to diagnose and treat dentin hypersensitivity in practice are challenging to justify.

Clinical implications: Practitioners should be aware of the diversity of methods available for diagnosing and treating dentin hypersensitivity as they manage the care of their patients with this condition.
