Effectiveness of Two Different Desensitizing Dental Varnishes

May 27, 2026 updated by: Ivoclar Vivadent AG

Effectiveness of Two Different Desensitizing Dental Varnishes: A Prospective, Randomized Split Mouth Clinical Investigation

Dental varnishes are commonly used to relieve dentin hypersensitivity by forming a protective film that occludes dentinal tubules and reduces fluid flow. This clinical investigation aims to compare the desensitizing effect of a fluoride containing varnish with a fluoride free placebo varnish. Primary and secondary objectives include evaluating short and long term reductions in dentinal hypersensitivity, assessing patient reported outcomes and daily experiences, and monitoring the varnish's tolerability and safety.
