Objective: The aim of this clinical study was to determine the desensitization effect of the calcium glycerophosphate-containing dentifrice at bed time.
Methods: Patients with symptoms of mild to severe dentin hypersensitivity between 20 and 40 years of age were allocated into two groups; the experimental group and the control group. Each group had used the dentifrice containing or excluding calcium glycerophosphate for 3 weeks. Symptoms of all participants were measured at baseline, after 3 days, 5 days, 1 week, 2 weeks and 3 weeks by the air blow method and the electric pulp tester (EPT).
Results: Symptoms of dentin hypersensitivity measured by the air blow method decreased in the experimental group (from 6.03 at baseline to 5.85 at 3 days, 5.36 at 5 days, 5.09 at 1 week, and 4.75 at 2 weeks) and there was a significant difference in the reduction effect after 5 days (p＜0.05). With the EPT method, there was a statistically significant difference in the hypersensitivity reduction effect in the experimental group after 1 week (from 18.80 at baseline to 18.80 at 3 days, 19.17 at 5 days, 21.33 at 1 week, and 22.30 at 2 weeks, p＜0.05).
Conclusion: The use of a dentifrice containing calcium glycerophosphate at bedtime produced significant reductions in hypersensitivity and rapid effects in relieving hyperesthesia, compared with the control group.
