Study Summary

This study will evaluate fluoride (F) bioavailability in saliva when using an over-the-counter mouthrinse of 226 ppm F, immediately after brushing with an over-the-counter toothpaste of 1,100 ppm F or a prescription toothpaste of 5,000 ppm F. The study population will include twenty individuals, over the age of 18 years-old, from both genders, with normal oral health conditions and salivary flow rate, no need of urgent dental needs, from the Ann Arbor, MI area. Participants will be recruited from the University of Michigan School of Dentistry, in Ann Arbor, MI. Using a crossover design, twenty participants will be rotating through 4 different combinations of fluoride toothpaste (over-the-counter or prescription concentration) and fluoride mouth rinse (yes or no), in a 2 x 2 factorial design. Treatments to be tested will be as followed: Group #1 will brush with 1,100 ppm F (over-the-counter) toothpaste; Group #2 will brush with 1,100 ppm F (over-the-counter) toothpaste and rinse with over-the-counter 226 ppm F mouthrinse; Group #3 will brush with 5,000 ppm F (prescription) toothpaste; Group #4 will brush with 5,000 ppm F (prescription) toothpaste and rinse with over-the-counter 226 ppm F mouthrinse.

Primary Outcome

Fluoride concentration in saliva will be measured before (baseline) and up to 60 min after the interventions, and the area under the curve of fluoride concentration versus time will be calculated to estimate bioavailability
