Comparative evaluation of efficacy of commercially available calcium sodium phosphosilicate and potassium nitrate containing toothpaste in reducing dentinal hypersensitivity

Aim: Dental hypersensitivity is commonly complained by the subjects in the dental office or hospitals. Our chief aim was to compare two commercially available toothpastes containing Calcium sodium phosphosilicate and 5% potassium nitrate for the treatment of dentinal hypersensitivity. Materials and methods: Sixty subjects with the chief complaint of dentinal hypersensitivity were selected and randomly divided into two groups. Assesment of hypersensitivity was done using visual analog scale (VAS) scores by applying water and air stimuli at baseline, 3 weeks after usage of the respective provided toothpaste, and 3 weeks after discontinuation i.e., 6 months of the respective toothpaste. Results: Both the groups showed reduction in hypersensitivity scores at 3 weeks and 6 weeks for air and water stimulus. The group provided with toothpaste containing potassium nitrate, however, showed significantly better reduction in hypersensitivity compared to the group provided with toothpaste containing calcium sodium phosphosilicate
