“…Generally speaking, the strategy of the fluoride application is to render the tooth tissue more resistant against acid attacks 1) . In literature, a number of studies showed that fluoride application is able to reduce erosive substance loss, calcium release, and surface softening of enamel and dentine [2][3][4][5][6][7] . Overall, although clinical studies regarding the erosion-inhibiting potential of fluoridation are not yet available, the protective effect of fluoride application on erosion progression have been shown both in vitro and in situ.…”

This study aimed to investigate the effect of topical fluoride application on the acid susceptibility of restorative materials. Four restorative materials were investigated in this study: 2 composite resins (Tetric EvoCeram and Filtek Silorane), a polyacid-modified resin composite (Dyract Extra), and a conventional glass-ionomer cement (Ketac Fil Plus). The samples were treated once with 1 of 8 different fluoride solutions (TiF4, NaF, AmF, and SnF2, each at native pH or pH 4) for 3 min or remained untreated (control). The samples were then eroded by citric acid (pH 2.6) for 5 days (6×1 min daily). Erosive substance loss, surface topographic and compositional changes were investigated using surface profilometry, scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS), respectively, after fluoride pretreatment and after erosion. The results indicate high-concentrated AmF solution at native pH was effective in inhibiting erosion in the conventional glass-ionomer cement and polyacid-modified resin composite.

“…[12][13][14][15][16] However, in the case of enamel, this effect was less pronounced when the abrasion of dentifrices with different abrasivity on eroded specimens was investigated in situ. 17,18 A possible explanation could be that over a short (clinically relevant) period of time, a softened layer of less than 0.5 µm thickness of eroded enamel is easily removed, independently of the abrasivity of the dentifrice.…”

Dental erosion is the loss of dental hard tissues caused by nonbacterial acids. Due to acid contact, the tooth surface becomes softened and more prone to abrasion from toothbrushing. Dentifrices containing different active agents may be helpful in allowing rehardening or in increasing surface resistance to further acidic or mechanical impacts. However, dentifrices are applied together with brushing and, depending on how and when toothbrushing is performed, as well as the type of dentifrice and toothbrush used, may increase wear. This review focuses on the potential harmful and helpful effects associated with the use of dentifrices with regard to erosive wear. While active ingredients like fluorides or agents with special anti-erosive properties were shown to offer some degree of protection against erosion and combined erosion/abrasion, the abrasive effects of dentifrices may increase the surface loss of eroded teeth. However, most evidence to date comes from in vitro and in situ studies, so clinical trials are necessary for a better understanding of the complex interaction of active ingredients and abrasives and their effects on erosive tooth wear.

“…39 In addition, the effects of fluoride may be partly masked by the abrasivity of the dentifrice. 14,38 Some reduction of available ions (tin) may occur in dentifrices due to their adsorption to the negatively charged silica.…”
