- Fluoride can protect enamel from demineralisation and promote remineralization.
- A sodium fluoride/potassium nitrate/cocamidopropyl betaine dentifrice was examined.
- Compared to a NaF/KNO3/sodium lauryl sulphate/tetrasodium pyrophosphate dentifrice.
- Greater salivary fluoride/calcium ion concentration found with the test dentifrice.
- Formulation excipients may impact fluoride and calcium ion oral cavity retention.
OBJECTIVE: This exploratory, randomised, single-blind, crossover, study evaluated fluoride and calcium ion concentrations and pH following use of one of two 1450 ppm fluoride (NaF), 5% w/w KNO3 dentifrices: (1) test dentifrice (with cocamidopropyl betaine) with an orange juice (OJ) rinse; (2) test dentifrice with a deionized (DI) water rinse or (3) comparator dentifrice (with sodium lauryl sulphate and tetrasodium pyrophosphate) with an OJ rinse.
DESIGN: Eighteen participants used their assigned dentifrice, rinsed with DI water, then expectorate was collected. Sixty min post-brushing, participants rinsed with OJ or DI water then expectorate was collected. Saliva samples were collected pre-brushing and at 1, 5, 10, 15, 30 and 60 min post-brushing and following the 60 min OJ/DI water rinse. The pH of samples was taken.
RESULTS: Significant differences (p < 0.05) were found in salivary fluoride ion concentrations between test and comparator dentifrices at 30 and 60 min and following the 60 min OJ rinse, favouring the former. Significant differences were also found between test and comparator dentifrices for salivary calcium ion concentration at 1, 5 and 10 min (p < 0.0001), favouring the former, and between test or comparator + OJ rinse and test + water rinse (p < 0.005), favouring the latter. No pH differences were shown prior to OJ/water rinse. Products were generally well-tolerated.
CONCLUSIONS: Results confirmed that acid-labile fluoride is released from the oral cavity following a dietary acid challenge and showed that formulation excipients may impact on retention of such.

[Fluoride levels in saliva after tooth-brushing using fluoride toothpastes with and without rinsing of oral cavity].
PURPOSE: The aim of the study was to determine salivary fluoride concentrations after tooth-brushing with fluoride toothpastes with and without rinsing of oral cavity. MATERIAL AND METHODS: Fluoride levels in the supernatant of unstimulated mixed saliva were measured after tooth-brushing with Elmex (amine fluoride, 0.125% F) and Meridol (amine fluoride, stannous(II)
Fluoride Levels in Saliva and Plaque following the Use of High Fluoride and Conventional Dentifrices- a Triple Blinded Randomised Parallel Group Trial.
Context: The comparison of fluoride levels in saliva and plaque following the use of conventional, 2800 and 5000 ppm dentifrices for different time intervals up to 24 hours has not been explored. Aim: The aim of the present study was to assess salivary and plaque fluoride levels at different time intervals
Salivary fluoride concentration following toothbrushing with and without rinsing: a randomised controlled trial.
Background: Caries prevalence has declined significantly since the introduction of fluoridated toothpaste. There have been several developments regarding specific active fluoride ingredients but not enough evidence to support one over the other. The purpose of this double-blind randomized controlled trial was to compare salivary fluoride concentrations of different
Randomised study of intra-oral kinetics of fluoride-containing toothpastes.
Objectives: This randomised, controlled, analyst blind, crossover study aimed to evaluate and compare salivary fluoride and calcium ion concentration over 60 min following brushing with an assigned treatment and following an orange juice (OJ) or deionised (DI) water rinse 60 min post-brushing. Methods: Study treatments, both containing
Assessing Fluorosis Incidence in Areas with Low Fluoride Content in the Drinking Water, Fluorotic Enamel Architecture, and Composition Alterations.
There is currently no consensus among researchers on the optimal level of fluoride for human growth and health. As drinking water is not the sole source of fluoride for humans, and fluoride can be found in many food sources, this work aimed to determine the incidence and severity of dental

Fluoride Dentrifice and Stomatitis
Statistical data of 133 patients who have been using fluoride dental cream or powder have been presented. Each has developed intraoral ulcerative lesions. Many have been treated for other complaints without clearance of the lesions. Age is not significant. Repeated insults with the fluoride dentrifices produced increasingly severe excoriations. There seems to be nothing specific about the lesions to differentiate them from other diseases of an oral nature.
Acute Fluoride Toxicity from Toothpaste Ingestion
The Food & Drug Administration now requires that all fluoride toothpastes sold in the United States bear the following poison warning: "WARNING: Keep out of reach of children under 6 years of age. If you accidentally swallow more than used for brushing, seek professional help or contact a poison control center immediately." The
Allergy to Fluoride
Six children and one adult exhibited various allergic reactions after the use of toothpaste and vitaimin preparations containing fluoride. The following conditions were encountered: Urticaria, exfoliative dermatitis, atopic dermatitis, stomatitis, gastro-intestinal and respiratory allergy.
Fluoride & Perioral Dermatitis
Perioral dermatitis (PD) is a common rosacea-like dermatitis that was never reported prior to the mid-fifties. Although it can affect both sexes and all ages, most patients are women ages 20-50 years. Patients with PD frequently report a pre-existing tendency to blush. This disease is most likely multifactorial in origin, and fluoride preparations in dentrifices probably have played a role as precipitator.
Fluoride Toothpaste: A Cause of Perioral Dermatitis
We have gathered clinical and historical data implicating fluoride dentrifices as an important etiologic factor in this dermatosis. The following two cases support this observation.
