Materials and Methods:- A total of ninety (90) samples were used in the study, for dentin permeability test (dye penetration test) and Scanning Electron Microscopic examination (SEM) which were randomly divided into two main groups; group A1, completely removed smear layer, group A2, partially removed smear layer. Each group was subdivided into three subgroups according to the desensitizing agent applied: OliNano SEAL, Curodont D'Senz and the control group that were left untreated. Seventy (70) hypersensitive teeth in ten patients were enrolled for the current study. The subjective assessment of dentin hypersensitivity was done prior to the application of the desensitizing agent (baseline) then immediately, 2 weeks, 4 weeks and 3 months after application of the tested materials. Patients were informed to rate their perception to tactile, air and cold stimuli by using Verbal Rating Score (VRS) and Visual Analogue Scale (VAS).
This study was conducted to evaluate and compare the efficacy of Olinanoseal and Curodont D'Senz in treatment of dentin hypersensitivity.
