Filter by:A dental gel intended to relieve pain related to dentin hyper sensitivity is commercialized in several countries worlwide since May 2017. Its efficacy and tolerance has already been proven in dentin hyper sensitivity. In this new study, we assess the efficacy and tolerance of this tested product in a specific external agression, the teeth whitening.
The study investigates the effect of toothbrushing with a toothpaste containing blue covarine compared to a control toothpaste without blue covarine on tooth color. Participants brush their teeth once with either the blue covarine containing toothpaste or a control toothpaste for two minutes. Before and after brushing, tooth color is assessed with a spectrophotometer. Moreover, satisfaction of the participants with their tooth color is assessed using a numeric analogue scale before and after treatment. The null hypotheses are that neither brushing with the toothpaste containing blue covarine nor brushing with the control toothpaste change a) the tooth color and b) the satisfaction of the participants with their tooth color.
Introduction: The pain sensitivity associated with whitening is the main problem reported by patients during dental whitening, and the use of desensitizing dentifrices is an alternative for the treatment of sensitivity. Objective: To evaluate clinically the influence of desensitizing dentifrices applied through a plastic tray, reducing the pain sensitivity and color variation caused by the technique of in-office dental whitening, through a controlled double-blind clinical study. Methods: A longitudinal prospective study was conducted with 48 individuals, 18 years and 30 years of age, without gender distinction, who underwent in-office dental whitening using 35% hydrogen peroxide (Whiteness HP, FGM, Joinville , SC, Brazil) in three clinical sessions with a one-week interval between them. The volunteers used in the night for each bleaching session a plastic tray for 4 hours containing one of the dentifrices related to the experimental groups: Group 1 (Control) - Sucralose (S) (Biotype - Manipulation pharmacy); Group 2 (Active control) - Sodium fluoride (FS) with 1450ppm of fluorine (Close up triple, Unilever); Group 3 - Arginine, calcium carbonate (ACC) and sodium monofluorophosphate with 1450 ppm fluorine (Colgate sensitive pro-relief, Colgate-Palmolive); Group 4 - 5% potassium nitrate (NP) and sodium fluoride with 1450 ppm fluorine (Sensodyne pro-enamel, GlaxoSmithKline). The evaluation of the sensitivity associated with the times of use of the plastic tray in the first session (S1: sensitivity before the tray, S2: sensitivity after the tray), in the second session (S3: sensitivity before the tray, S4: in the third session (S5: sensitivity before the tray, S6: sensitivity after the tray) used the analog numerical scale with scores from 0 to 10 and for the color evaluation the spectrophotometer (Easyshade, Vident, Brea, CA, Obtaining the data that were used in the CIELab system. The data were submitted to the multivariate analysis of variance (MANOVA) with repeated measurements and Lambda Wilks test with a 5% probability level to differentiate the groups. In addition, the factorial variance analysis (ANOVA) in one criterion was applied. Values of p <0.05 were considered statistically significant.
The purpose of this study is to determine the effect of REMEWHITE on tooth whitening.
