Details and patient eligibility

About

Individuals with dry mouth (a reduction in the production of saliva) suffer from high rates of oral diseases. Dry mouth is a common problem among older individuals, because many medications to control chronic conditions (such as blood pressure, bladder-control problems and depression) reduce the flow of saliva. For these individuals, fluoride is used to maintain a good oral health. Usually, higher fluoride concentration products, such as prescription toothpastes, are recommended. In this project, the ability to increase fluoride retention in the mouth by using calcium before a conventional fluoride rinse will be tested in older adults with a range of salivary flow rates. This approach was never tested in patients with dry mouth, for whom the treatment with calcium may also be beneficial. A crossover, clinical study with two experimental phases will be conducted, in which patients with a range of saliva flows (from normal to dry mouth) will rinse with a fluoride rinse only (used at over the counter concentration), or a fluoride rinse preceded by a calcium rinse. The concentration of fluoride and calcium in the saliva and dental plaque residues will be determined up to two hours after the rinse(s), to test the effect of the approach to optimize fluoride retention in the mouth of patients with dry mouth.

20 participants in 2 patient groups

Fluoride mouthwash alone, then Calcium mouthwash before a fluoride mouthwash
Experimental group
Description:
Participants with normal to dry mouth will first test a Fluoride mouthwash containing 226 ppm of fluoride, and fluoride concentration in saliva and dental biofilm will be assessed overtime for up to 2 hours. After a washout period of at least 3 days, they will then test a Calcium mouthwash (150 milimolars of calcium) immediately before the Fluoride mouthwash, and fluoride concentration in saliva and dental biofilm will be assessed overtime for up to 2 hours.
Treatment:
Drug: Calcium and fluoride mouthwash
Drug: Fluoride mouthwash
Calcium mouthwash before a fluoride mouthwash, then Fluoride mouthwash alone
Experimental group
Description:
Participants with normal to dry mouth will first test a Calcium mouthwash (150 milimolars of calcium) immediately before a Fluoride mouthwash containing 226 ppm of fluoride, and fluoride concentration in saliva and dental biofilm will be assessed overtime for up to 2 hours. After a washout period of at least 3 days, they will then test the Fluoride mouthwash alone, and fluoride concentration in saliva and dental biofilm will be assessed overtime for up to 2 hours.
Treatment:
Drug: Calcium and fluoride mouthwash
Drug: Fluoride mouthwash
