Abstract
Objective: To investigate the effects of low-rinsing volume after toothbrushing with fluoride dentifrice (paste and gel denti-frice, 950 ppm F, new products with cationated cellulose and original products) on salivary fluoride retention.
Methods: Subjects comprised seven adults with a mean age of 40.8 years. Experimental groups were 1: New paste, rinse once with 15 ml of water, 2: New paste, rinse twice with 25 ml of water, 3: New paste, rinse four times with 30 ml of water, 4: Original paste, rinse once with 15 ml of water, 5: New gel, rinse once with 25 ml of water, 6: New gel, no rinsing, 7: Original gel, rinse once with 25 ml of water. They brushed their teeth for 3 min 30 s with 0.5 g of each dentifrice, after which six samples of unstimulated whole saliva were collected from immediately after brushing (0 min) to after 150 min.
Results: A statistical test for the AUC in group 1-4, fluoride retention was significantly higher in group1 and 4 (p＜0.01). In group 5-7, fluoride retention was highest in group 6 (p＜0.001). As a result of multiple regression analysis with the AUC con-cerning the factors influencing salivary fluoride concentration, volume of water, baseline salivary fluoride and the amount of fluoride remaining in the mouth were selected as explanatory variables.
Conclusion: For both the new and original products, larger rinsing volume and more number of rinses significantly reduced salivary fluoride retention after toothbrushing with fluoride dentifrice, yield to reduction of their cationated cellulose effects.
