of treated dentin specimens and the excellent tubule occlusion properties of Omyadent 200 are clearly visible. Image 2 shows how the particles themselves occlude tubules effectively, and there is even greater occlusion in a toothpaste containing 5% Omyadent 200 (Image 3).Omyadent 200 also shows excellent tubule occlusion when compared to the benchmarked competitor toothpastes (Images 4-6). These were all products marketed for targeted treatment of dentin hypersensitivity and based on different tubule occlusion mechanisms. In addition to morphology studies, Omyadent 200’s efficacy has been proven in a permeability (hydraulic conductance measurement) test, which showed that a single application of a silica toothpaste containing 5% Omyadent 200 effectively reduced permeability and indicated an immediate treatment effect. Triple treatment with the same toothpaste showed excellent flow reduction of 85% on average and thus excellent performance compared to a marketed toothpaste with a desensitization claim. In this study, a toothpaste marketed without a sensitivity claim was chosen as the negative control.
