“…The results differed from the observations described in the literature; several studies measured water contact angles between 40 and 50° on bare enamel [de Jong et al, 1982;van Dijk et al, 1987;Perdok et al, 1990]. However, different grinding procedures and especially varying pretreatments of the enamel with different buffer solutions such as SDS or sodium hypochlorite certainly affect the wettability of the surface, as does ultrasonication Muller et al, 2010a].…”

Aim: The study aimed to investigate the effect of a customary fluoride solution, containing sodium fluoride and amine fluoride, on initial biofilm formation on enamel and dentin in situ compared directly to chlorhexidine. Methods: Bovine enamel and dentin specimens were mounted on maxillary splints carried by 9 subjects. After 1 min of pellicle formation, rinses with tap water (control), chlorhexidine (meridol med CHX 0.2%, GABA) and a fluoride mouthrinse (elmex, GABA) were performed for 1 min. Subsequently, the slabs were carried for another 8 h. The adherent bacteria were determined by DAPI staining, live-dead staining and determination of colony-forming units after desorption; glucan formation was visualized with concanavalin A. Additionally, energy-dispersive X-ray spectroscopy (EDX) analysis of the in situ biofilm layers was conducted, and contact angle measurements were performed. Statistical evaluation was performed by means of the Kruskal-Wallis test followed by the Mann-Whitney U test (p < 0.05). Results: In the control group, significantly higher amounts of adherent bacteria were detected on dentin (4.8 × 10⁶ ± 5.4 × 10⁶ bacteria/cm²) than on enamel (1.2 × 10⁶ ± 1.5 × 10⁶ bacteria/cm², DAPI). Chlorhexidine significantly reduced the amount of adherent bacteria (dentin: 2.8 × 10⁵ ± 3.4 × 10⁵ bacteria/cm²; enamel: 4.2 × 10⁵ ± 8.7 × 10⁵ bacteria/cm²). Rinses with the fluoride solution also significantly reduced bacterial adherence to dentin (8.1 × 10⁵ ± 1.5 × 10⁶ bacteria/cm²). Fluoride could not be detected by EDX analysis of the biofilms. Fluoride mouthrinsing did not influence the wettability of the pellicle-covered enamel surface. Conclusion: In addition to the reduction of demineralization and antibacterial effects, fluorides inhibit initial biofilm formation on dental hard tissues considerably, especially on dentin.

“…coefficient of liquids. The viscosity of a drink, together with contact angle and surface tension, determines its penetration coefficient, 21 a measure of the ability of a liquid to penetrate into a capillary space such as pores. According to this theory a beverage with a low viscosity will have a high penetration coefficient and this results in a higher erosive potential.…”

“…In the present study, three mouthwashes were classified as potentially erosive (pH<5.5), corroborating the findings of previous investigations. 2,4,5,8,10 The low pH of oral care products increases the chemical stability of some fluoride compounds and favors the incorporation of fluoride ions into the lattice of hydroxyapatite and the precipitation of calcium fluoride onto the tooth surface. 11 Based on this statement, product labels were examined to identify mouthwashes containing fluoride.…”

Objectives:To evaluate in vitro the endogenous pH, titratable acidity and total soluble solid content (TSSC) of mouthwashes available in the Brazilian market.Methods:The study sample was composed of 10 commercial brands of mouthwashes based on different active ingredients: Cepacol®, Clinerize®, Equate®, Listerine Cool Citrus®, Oral-B®, Periogard®, Peroxyl®, Plax Overnight®, Prevident 220® and Sanifill®. The experiments were performed in triplicate. The endogenous pH was evaluated by potentiometry, titratable acidity was evaluated by the addition of 0.1N KOH increments to the mouthwashes, and TSSC readings were performed by Brix refractometry using the Abbé refractometer.Results:pH values ranged from 3.56 (Peroxyl®) to 7.43 (Cepacol®) and three mouthwashes presented pHs below 5.5. The titratable acidity values ranged from 0.007 (Periograd®) to 0.530 (Prevident®). Oral B® and Clinerize® presented the lowest (4.7%) and the highest (23.70%) TSSC, respectively.Conclusions:Some of the mouthwashes evaluated in this study presented low endogenous pH, even below the critical value for enamel dissolution (pH<5.5), high titratable acidity and high TSSC, and may be potentially erosive to the dental tissues if not properly used.
