Abstract
Objectives: To evaluate the effectiveness of sodium bicarbonate dentifrices in reducing gingivitis and tooth abrasiveness and improving tooth gloss, as compared to a conventional fluoride/silica-containing dentifrice.
Methods: In this double-blinded, randomized clinical study with a paralleled design, 73 healthy adult volunteers (age, 18-39 years), with more than 20 teeth were selected and randomly allocated to the following groups: a control group, a 35% baking soda group, and a 65% baking soda group. Professional plaque controls were provided to all subjects and the same control dentifrice was used for 14 days. At baseline, all subjects received an assigned dentifrice and were instructed to brush three times daily. The tooth gloss and gingival bleeding index were measured at baseline, 45, and 90 days. For measuring surface roughness, toothbrushes were replaced with electronic tooth-brushing machines, and the bovine specimen was brushed via 10,000 horizontal shuttle movements. The surface roughness was measured by a confocal laser scanning microscope (CLSM; Carl Zeiss, LSM-5 Pascal, Germany) Each variable was analyzed by the paired t-test, and change in each variable among groups was analyzed by analysis of variance (ANOVA). Reliability of the gloss was analyzed by an intra-class correlation coefficient.
Results: Compared to the controls, the 65% sodium bicarbonate dentifrice group showed significant improvement with regard to the tooth gloss for 90 days as well as a significant inhibitory effect on gingivitis; the 35% sodium bicarbonate dentifrice group, however, showed no inhibitory effect on gingivitis. The relative roughness of the tooth surface in the dentifrices of both the sodium bicarbonate dentifrice groups was significantly low. Further, there was no significant difference with the distilled water group.
Conclusions: The sodium bicarbonate dentifrice has an inhibitory effect on gingivitis. Further, this dentifrice showed low abrasiveness and a glossing effect on teeth.
