A single-site, randomized, controlled, double-blind, 3-arm parallel study by Neuhaus et al investigated the effectiveness of a prophylaxis paste containing 15% calcium sodium phosphosilicate (CSPS; NovaMin) with and without fluoride in reducing dentin hypersensitivity immediately after a single application and 28 days following dental scaling and root planing. The study involved 151 subjects; 149 subjects completed the study. All subjects received a scaling and root planing procedure followed by a final prophylaxis step using one of 3 different prophylaxis pastes: Test A (15% NovaMin and NaF), Test B (15% NovaMin), and a control. Dentin hypersensitivity was assessed by tactile stimulus (Yeaple Probe) and by air blast (Schiff scale) at baseline, immediately after and 28 days after a prophylaxis procedure. The study found that subjects who received the test prophylaxis pastes showed statistically lower (ANOVA, P < .05) dentin hypersensitivity compared to the control group immediately after the prophylaxis-procedure (Yeaple Probe: Test A = 20.9 ± 12.6, Test B = 22.7 ± 12.9, Control = 11.2 ± 3.1; Schiff score: Test A = 1.1 ± 0.6, Test B = 1.1 ± 0.6, Control = 2.0 ± 0.7) and after 28 days (Yeaple Probe: Test A = 21.5±11.9, Test B = 20.6 ± 11.3, Control = 11.8 ± 6.0; Schiff score: Test A = 1.0 ± 0.6, Test B = 1.0 ± 0.6, Control = 2.0 ± 0.7).
The authors conclude that the single application of both fluoridated and nonfluoridated prophylaxis pastes containing 15% CSPS (NovaMin) provided a significant reduction of dentin hypersensitivity up to at least 28 days.
