https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5121804/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5121804/ An In-vitro Comparison of Nano Hydroxyapatite, Novamin and Proargin Desensitizing Toothpastes - A SEM Study Results The qualitative analysis showed no occlusion of the dentinal tubules in Group A (control group) and Group B (nano-hydroxyapatite) showed 98.1% tubule occlusion. Group C (Novamin) and D (Proargin) showed 83.1% and 69.1% tubule occlusion respectively. Quantitative analysis showed a statistical significant difference between Group B and D (p< 0.005) and no statistical significant difference between group B and C (p= 0.235). Similarly, there was no significant difference between Group C and D as (p=0.235). Conclusion It was concluded that all the three desensiting agents were effective in the dentine tubule occlusion. In addition efficacy of nano-hydroxyapatite toothpaste was greater compared to the other desensiting agents.
