Commercial Silver Diamine Fluoride (SDF) Products on Caries Lesion Progression in Primary Enamel: An In Vitro Study.

Purpose: Evidence has shown that silver diamine fluoride (SDF) at 30-38% has the potential to control and revert caries lesions. However, SDF can be found at lower concentrations on the market. In this study, we evaluated the effect of different commercially available SDF products on the progression of non-cavitated caries lesion in primary teeth assessed by a pH-cycling model.

Erosive potential of powdered juice drinks on dental enamel.

This study aimed to evaluate the erosive potential of powdered juice drinks on dental enamel in 2 stages: physiochemical characterization and erosive challenge testing. In stage 1, the pH and titratable acidity of 5 commercially available powdered juices in 10 different flavors were analyzed. Five treatment groups were then established based on the pH values, titratable acidity, and presence of citric acid in the juices, and their energy-dispersive X-ray (EDX) spectroscopy profiles were studied.

Contextual and Individual Determinants of Root Caries in Older People.

The aim of this study was to identify the association of the presence of root caries in older people with contextual and individual determinants using a multilevel model. Data from the National Survey of Oral Health collected in Brazil were used. A sample of older Brazilians (aged 65-74 years) was included and selected through multistage probability cluster sampling, using probability proportional to size.

Effect of Fluoride Concentration on Reduction of Enamel Demineralization According to the Cariogenic Challenge.

Fluoride present in toothpaste at 1,100 µg/g is considered effective on caries control. However, under high cariogenic challenge due to increasing sugar exposure, higher fluoride concentration (5,000 µg/g) could be necessary to compensate the unbalance on caries process. This was tested in a pH-cycling regimen, which evaluated the effect of fluoride concentration relative to toothpaste on reduction of enamel demineralization under conditions of two levels of cariogenic challenge.

Evaluation of low fluoride toothpaste using primary enamel and a validated pH-cycling model.

Aim: To develop and validate pH-cycling model for primary enamel, which was then used to evaluate the anti-caries potential of fluoride toothpastes.

Design: Human primary enamel slabs were subjected to pH-cycling model for 10 days and maintained for 6 h in demineralizing solution and 18 h in remineralizing solution daily. Twice/day, the slabs were treated.
