Efficacy of 8% arginine on dentin hypersensitivity: A multicenter clinical trial in 273 patients over 24 weeks.

Abstract

OBJECTIVES:

To assess the efficacy of 8% arginine containing prophylaxis products over 24 weeks in subjects with dentin hypersensitivity (DH).

METHODS:

297 patients with established DH (Schiff score 2, 3) in three European study centers were randomly assigned to either 8% arginine and calcium carbonate in-office prophylaxis paste and the respective toothpaste (test group) or fluoride-free prophylaxis paste and sodium monoflourophosphate toothpaste as a negative control group. Air blast (Schiff Score) and tactile (Visual Analog Scale) sensitivity scores were assessed at baseline (BL_0), after single application of the prophylaxis paste (BL_1) and after 4, 8, and 24 weeks of continuous at-home use of the toothpaste.

RESULTS:

273 subjects completed the study. Test and control group presented statistically significant percentage reductions (t-test, p < 0.05) in Schiff Score at BL_1 and at 24 weeks relative to BL_0 (difference in %; test group: -23.6, -44.9, control group: -8.8, -32.7). The pooled Schiff Score for the two evaluated teeth yielded a significantly greater alleviation of DH in the test group than in the control group at all evaluation appointments (Ancova, p < 0.05; difference in %: 15.3, 7.4, 10.6, 17.2).

CONCLUSIONS:

A significant relief of DH was demonstrated after application of the 8% arginine prophylaxis products over 24 weeks compared to a negative control.

CLINICAL SIGNIFICANCE:

Whilst DH is influencing patients' eating, drinking and tooth brushing habits as well as social life interactions it is important that clinicians are able to offer evidence based immediate and long-lasting treatment methods in order to manage their patients' discomfort.
