“…A fundamental determinant of sufficient oral hygiene is brushing duration [13,38,39]. A recent systematic review on the efficacy of manual toothbrushes demonstrated that plaque removal was clearly better after brushing for 2 min (41 % mean plaque reduction) than for 1 min (27 % mean plaque reduction) [40].…”

“…It appears, therefore, that brushing behaviour that emphasises vestibular surfaces, while neglecting the oral areas, is a phenomenon that extends across differences in times, education and culture. Although there is consensus that sufficient time is necessary to clean teeth thoroughly, it is much less clear which brushing technique is most appropriate [13,39]. Generally, types of strokes are categorised as vertical, horizontal (jiggling) or circular and constitute defined brushing techniques (e.g.…”

“…It was designed to mimic frequent acid exposure and normal oral hygiene habits. The immersion time in the slurries was 2 min twice daily, which is within the range of recommendations for proper oral hygiene [dos Santos et al, 2011]. Assuming an overall brushing time of 2 min, approximately 30 s is spent on each quadrant; thus, a brushing time of 15 s for our samples approximated clinically recommended conditions for brushing.…”

The study investigated the erosion/abrasion-preventing potential of experimental NaF (1,400 ppm F^-) and amine fluoride (AmF)/NaF/SnCl₂/chitosan (1,400 ppm F^-, 3,500 ppm Sn²⁺, 0.5% chitosan) toothpastes relative to placebo and SnF₂ gel (970 ppm F^-, 3,000 ppm Sn²⁺), and the impact of the demineralised dentine matrix on toothpaste effects. The study was a cyclic erosion/intervention experiment (10 days). Samples were stored in mineral salt solution either without or with collagenase (from Clostridium histolyticum type VII; 100 U/ml) for continuous removal of the organic matrix. To produce a comparable order of tissue loss, erosion was performed 6 × 30 s/day with 0.5% citric acid in the latter and 6 × 90 s/day with 1% citric acid in the former. Intervention was toothpaste slurry immersion (2 × 2 min/day); half of the samples were additionally brushed for 15 s within this time (brushing machine, load 200 g). Tissue loss was determined profilometrically (mean ± SD; µm). Tissue loss values (without/with brushing) for placebo, NaF, AmF/NaF/SnCl₂/chitosan and SnF₂ gel, respectively, were 11.6 ± 3.1/12.2 ± 2.5, 12.7 ± 3.1/10.7 ± 4.5, 8.7 ± 2.1/9.7 ± 2.1 and 8.8 ± 1.8/10.9 ± 1.8 in the presence of the organic matrix and 10.7 ± 3.2/11.9 ± 2.1, 8.2 ± 4.0/10.1 ± 4.1, 8.7 ± 2.9/9.1 ± 1.8 and 8.4 ± 1.9/7.5 ± 1.5 in the absence of the organic matrix. Relative to placebo, the NaF formulation had no significant effects; the AmF/NaF/SnCl₂/chitosan formulation significantly reduced tissue loss between 20 and 25% except when applied without brushing in the absence of the organic matrix. The effects of the formulations were similar both in the presence and absence of the organic matrix. Sn²⁺/F^--containing formulations have the potential to reduce erosion/abrasion even in the absence of demineralised collagen; seeking for more effective formulations is desirable.

“…However, the increasing concern in the risk of fluorosis development may jeopardize this benefit, favoring the recommendation of fluoride-deficient toothpastes for young children [dos Santos et al, 2011;Giacaman et al, 2012], to which scientific evidence of anticaries effect is lacking [Walsh et al, 2010;dos Santos et al, 2012]. Moreover, fluorosis risk assessment and resulting recommendation protocols have been made based on the dose of fluoride ingested by young children, without considering the bioavailable fluoride dose.…”

Depending on toothpaste formulation, part of the fluoride is insoluble and would not be totally absorbable in the gastrointestinal tract, thus changing dental fluorosis risk estimation. This hypothesis was tested with formulations with either all fluoride in a soluble form (NaF/SiO₂-based toothpaste, 1,100 µg F/g as labeled, 1,129.7 ± 49.4 µg F/g soluble fluoride as analyzed) or with around 20% of insoluble fluoride (Na₂FPO₃/CaCO₃-based toothpaste, 1,450 µg F/g as labeled, 1,122.4 ± 76.4 µg F/g soluble fluoride as analyzed). Toothpastes were evaluated either fresh or after accelerated aging, which increased insoluble fluoride to 40% in the Na₂FPO₃/CaCO₃-based toothpaste. In a blind, crossover clinical trial conducted in five legs, 20 adult volunteers ingested 49.5 µg of total fluoride/kg body weight from each formulation or purified water (control). Whole saliva and urine were collected as bioavailability indicators, and pharmacokinetics parameters calculated showed significantly (p < 0.05) lower fluoride bioavailability for Na₂FPO₃/CaCO₃ toothpaste, which was reduced further after aging. A significant correlation between the amount of soluble fluoride ingested, but not total fluoride, and fluoride bioavailability was found (r = 0.57, p < 0.0001). The findings suggest that the estimated fluorosis risk as a result of ingestion of Na₂FPO₃/CaCO₃-based toothpastes should be calculated based on the toothpaste’s soluble rather than total fluoride concentration.
