Abstract Background Dentin hypersensitivity, often occurring after dental treatments or from erosive lesions, is a prevalent patient complaint. This study introduces paste combining 8% L-arginine, calcium carbonate, and potassium nitrate to evaluate its impact on dentinal tubules occlusion, dentin permeability, tooth sensitivity. Methods surfaces 24 third molars (thickness: 2 mm) were divided into two groups of 12. One received the experimental paste, while other placebo without...
