Inhibition Effects of Different Toothpastes on Demineralisation of Incipient Enamel Lesions

Altan, Halenur / G öztaş, Zeynep / Kahraman, Kamil / Kuş, Mahmut / Tosun, GulPage 179 - 185Purpose: To evaluate the inhibitory effects of different toothpastes on demineralisation of incipient enamel lesions using a toothbrush simulator.Materials and Methods: Fifty enamel specimens were prepared from extracted human molars. The specimens were randomly assigned to the following groups (n = 10/group): 1. no treatment (control); 2. toothpaste containing arginine (ProRelief, Colgate;); 3. fluoride toothpaste (Pronamel, Sensodyne GlaxoSmithKlein); 4. tooth mousse containing casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) (Recaldent, GC); 5. toothpaste (Restore, Dr. Collins) containing bioactive glass (NovaMin, GlaxoSmithKlein). All specimens were exposed to pH cycling. The remineralising agents were applied to the samples with a toothbrush simulator for 2 min twice a day for five days. The weight percentage of mineral changes for the elements calcium (Ca), phosphorus (P), sodium (Na) and silica (Si) were measured by SEM energy-dispersive x-ray spectroscopy (SEM-EDX). SEM revealed properties of treated enamel surfaces. The data were analysed using one-way ANOVA.Results: Statistically significantly higher levels of Ca and P were found in all groups compared to the control (p
