| Title |
Fluoride Retention Greater if no Post Brushing Water Rinsing Routine is Used |
| Clinical Question |
In adults, does not rinsing with water after brushing teeth with fluoride toothpaste versus rinsing after brushing teeth with fluoride toothpaste increase fluoride retention? |
| Clinical Bottom Line |
Fluoride retention is greater without post brushing water rinsing compared to rinsing with water after brushing with fluoride toothpaste. |

| #1) 19204390 | Nordstom/2009 | 26 healthy, aged 19- | Randomized Controlled trial, 4-leg | | Key results | Fluoride retention in plaque and saliva was highest after using 5,000 ppm F toothpaste without post brushing water rinsing compared to using 1,450 ppm F toothpaste with
water rinsing which had the lowest retention. The increase of F in plaque between 1,450/rinsing
and 5,000/no rinsing was 2.1 times (2.7/1.3) expressed as ppm F and 2.75 (0.11/0.04) times
expressed on a weight basis (both, p<0.05). The increase of F in saliva using toothpaste with
5,000 ppm F without postbrushing water rinsing was 4.2 times (685/165; p< 0.001) compared to
1,450 ppm F toothpaste with water rinsing. | | #2) 11813383 | Sjogren/2001 | 21 healthy, aged 23 | Randomized Controlled Trial | | Key results | In saliva, the concentration of fluoride increased as an effect of the increased volume of water, but not as an effect of duration of rinsing (p=0.023). The difference in fluoride concentration in saliva was significant with respect to the amount of water (10mLx3 compared to 5mL at various rinsing times; p<0.05) and compared to fluoride-free brushing (p<0.001). | | #3) 14684972 | Issa/2004 | 10 healthy adults | Double-blind study | | Key results | Using AmF toothpaste (1,400 ppm F) resulted in the highest fluoride content of saliva without water rinsing after 120 min (0.52 ppm F, Cl 0.23, 0.81). | |

Comments on
The Evidence |
Patient groups could be larger. However, the articles all supported the notion that fluoride retention is greater with no post brushing rinsing routine is. |
| Applicability |
In order to achieve the maximum anticaries effect from home care, there should be emphasis on post brushing routines. Applies especially to patients who are at risk of developing caries. |
