Aim: To evaluate the effectiveness of three different pastes containing 5% NovaMin, 8% arginine, and 15% hydroxyapatite nanoparticles (n-HA) respectively in the treatment of dentin hypersensitivity (DH). Materials and Methods: A 4 weeks study was conducted on 45 adult patients with cervical abrasions leading to hypersensitivity of two or more teeth anterior to molars. Patients were divided into three toothpaste groups. Group I: 5% NovaMin, Group II: 8% arginine, Group III: 15% n-HA. Sensitivity was assessed at baseline, immediately after application and after 1-week and 4 weeks. Tactile stimuli response using a visual analog scale and standard cold air blast using Schiff cold air sensitivity scale were used to compare the efficacies of toothpastes after a single application. Statistical Analysis: Two-way analysis of variance and post-hoc Tukey test were used and P ≤ 0.05 was considered statistically significant. Results: Visual analog scale analysis: Group III and Group II showed statistically significant reduction in DH at all-time intervals when compared with Group I. In SCA analysis there is no statistically significant difference between Group II and Group III immediately after application. Conclusion: Toothpaste containing 15% n-HA was found to be most effective in reduction of DH after a single application up to a period of 4 weeks followed by 8% arginine and 5% NovaMin toothpastes.
