Background: Dental hypersensitivity (DH) is a common oral disease characterized by a short and sharp sensation of pain in response to thermal, tactile, osmotic, evaporative or chemical stimuli. The present study was conducted to assess the efficacy of in-office calcium-phosphate-based desensitizer. Materials & Methods: The present study was conducted on 45 patients with complaint of dental hypersensitivity since 2 months. They were divided into 3 groups ie TMD vs TMDSS, TMD vs NaFV and TMDSS vs NaFV. The selected product was applied with a brush for 30 seconds. The first outcome taken into consideration was the residual DH, respectively, at 15 days, then 3 months, and then 6 months after treatment. Results: The VAS scale estimated marginal means; there was a significant pain reduction at t1, t2 and t3 vs t 0 in the TMD group (p<0.05). Similarly in the TMDSS group and NaFV treatment, there was a significant reduction at t1, t2 and t3 (p<0.05). Conclusion: Authors found that with the progression of time, dental hypersensitivity decreases. All materials found to be equally effective.
Key words: Dental hypersensitivity, Pain, Tactile.
