PURPOSE To compare the long-term caries increment associated with the use of two dentifrices: (1) a test dentifrice containing 0.836% sodium monofluorophosphate (1100 ppm F) in a dicalcium phosphate dihydrate base plus 10% xylitol; and (2) a positive control dentifrice containing 0.836% sodium monofluorophosphate (1100 ppm F) in a dicalcium phosphate dihydrate base. MATERIALS AND METHODS Thre...

Recently, a novel antibacterial fluoride dentifrice containing stannous fluoride and sodium hexametaphosphate (Crest ® PRO-HEALTHTM) was introduced. A digital plaque image analysis (DPIA) technique was used to quantify in situ plaque formation in a population carrying out a phased intervention protocol that included: (1) an initial treatment regimen including toothbrushing with standard sodium ...

The low concentration of available calcium (Ca) in oral fluids limits the formation of Ca-mediated fluoride deposits that maintain oral fluoride (F) after a topical F treatment. The purpose of this study was to examine if a high concentration of Ca would increase salivary F when used before a F rinse or dentifrice. We found that a Ca pre-rinse (150 mmol/l Ca lactate) or Ca dentifrice (0.084 g C...

were worn for 96 hr by seven adult males who brushed daily with a F-free dentifrice. Test slabs were brushed with a NaF dentifrice 4 x / day or with the same dentifrice 4 x /day and a 0. 02% APF mouthrinse and a 0.4% SnF2 gel which were applied once/day for three days. The natural dentition was also brushed with the NaF dentifrice during both test periods. Microhardness testing was performed on...

Patients who have undergone irradiation for head and neck tumors commonly have xerostomia. Loss of the protective constituents normally found in saliva leaves patients at greater risk for development of significant dental pathologic disorders, including gingival and periodontal disease. Periodontal disease and tooth extractions are currently accepted as etiologic factors for the development of ...

The objective of this study was to determine the effects of a triclosan/copolymer dentifrice on plaque formation, gingivitis and gingival bleeding in pregnant subjects. This double-blind clinical study was carried out in 180 women at 3 months of pregnancy. The subjects were stratified into two balanced groups according to their baseline plaque, gingivitis and bleeding scores. Subjects received ...

Sodium lauryl sulfate (SLS), a synthetic detergent commonly used in dentifrices, is an effective denaturant. The aim of the present study was to investigate the effect of SLS in patients with recurrent aphthous ulcers (RAU). Ten patients with multiple minor RAU participated in the study. The mean incidence of RAU was 17.8 during a 3-month period before the study. The patients used a dentifrice ...

In this study, antimicrobial toothpaste (dentifrice), which can compete with existing toothpaste, was produced using Moringa oleifera root essential oil extract. The extract 2 ml per 100 g obtained, gave peppermint flavor and volatile. phytochemical screening revealed a high concentration of flavonoid, bioactive agent activity in nature. 0.5 the concentrate used to produce 120 gm novel dentifri...
