“…However, the efficacy of fluoride varnishes and gels in decreasing demineralization and enhancing remineralization of dental hard tissues is similar. 22,23 On the other hand, the protective effects of laser irradiation of enamel and dentine from demineralization have gained increasing attention in recent years. Several types of lasers, such as ruby, CO 2 , Nd:YAG, and argon, with different operational modes and energy outputs have been investigated.…”

Objective: In this paper we evaluated the effect of two fluoridated agents and Nd:YAG irradiation separately and in combination on dentine resistance to erosion. Background Data: The morphological changes in dentin induced by laser treatment may reduce the progression of erosive lesions. Due to the possibility of a synergistic effect of laser with fluoride, this study was conducted. Materials and Methods: Eighty bovine dentine samples (4 ϫ 4 mm) were randomly divided into eight groups, according to the following treatments: G1: untreated (control); G2: acidic phosphate fluoride gel (APF 1.23%) for 4 min; G3: fluoride varnish (NaF 2.26%) for 6 h; G4: 0.5 W Nd:YAG laser (250 sec pulse, 10 Hz, 35 J/cm 2 , 30 sec); G5: 0.75 W Nd:YAG laser (52.5 J/cm 2 ); G6: 1.0 W Nd:YAG laser (70 J/cm 2 ); G7: APF ϩ 0.75 W Nd:YAG laser; and G8: NaF ϩ 0.75 W Nd:YAG laser. After the treatments, half of each dentine surface was protected with nail varnish. The samples were stored in artificial saliva (30 mL/sample) for 24 h and submitted to four erosive 1-min cycles. Between the erosive attacks, the blocks were maintained in artificial saliva for 59 min. The erosive wear was evaluated by profilometry. Results: The mean wear (ϮSD, m) was: G1: 1.20 Ϯ 0.20; G2: 0.47 Ϯ 0.06; G3: 0.81 Ϯ 0.11; G4: 1.47 Ϯ 0.32; G5: 1.52 Ϯ 0.24; G6: 1.49 Ϯ 0.30; G7: 0.49 Ϯ 0.11; and G8: 1.06 Ϯ 0.31 (Tukey's test, p Ͻ 0.05). Conclusions: Laser irradiation was not able to reduce dentine erosion. However, fluoride application was able to increase the dentine's resistance to erosion, and APF showed better results than fluoride varnish. 559

“…Recent reports have indicated that frequent application of fluoride protects enamel against erosion by wine 17 and soft drinks. 22 Intensive application of fluoride has also been shown to reduce enamel and dentine erosion by strong acids, 23 even under conditions simulating gastric reflux. 24 Future studies are needed to compare the relative benefits of CPP-ACP and fluoride, when used individually or in combination, in preventing dental erosion.…”

Background: The recommendation that Tooth Mousse (TM), an anticariogenic remineralizing agent, is effective for controlling dental erosion in professional wine tasters is not evidence‐based. The aim of this in vitro study was to determine the effectiveness of TM in reducing erosion of coronal enamel and radicular dentine/cementum simulating a typical wine judging session.Methods: Enamel and dentine/cementum from buccal halves (experimental sample) and palatal halves (control sample) of human maxillary premolar teeth were subjected to 1500 one‐minute exposures (cycles) to white wine (pH = 3.5). TM was applied every 20 cycles to the experimental sample, but not to the control sample. Paired t‐tests were used to determine whether there were significant differences in erosion depths between the experimental and control samples.Results: Mean erosion depths were significantly shallower in the experimental sample than the control sample for both enamel (34.4 μm versus 49.2 μm, respectively) (p < 0.05) and dentine/cementum (143.2 μm versus 203.7 μm, respectively) (p < 0.01).Conclusions: TM may have significant role in the management of wine erosion, which is under‐recognized as an occupational hazard by the Australian wine industry. Future studies are needed to compare the relative benefits of TM and other remineralizing agents, when used individually or in combination, in preventing dental erosion.

“…Most of these studies applied cycling models with alternating de-and remineralisation phases. Alternating erosion/abrasion treatment also showed a great variety from 3 days with 2 cycles/ day [Hara et al, 2003;Turssi et al, 2004] up to 21 days with 3 cycles/day [Vieira et al, 2007]. Erosion and abrasion were mostly performed extra-orally, and only in a few studies was either demineralisation [Hooper et al, 2003] or brushing [Jaeggi and Lussi, 1999;Lussi et al, 2004] done with the appliances in situ.…”

In vitro and in situ studies modelling the wear of dental hard tissues due to erosion and abrasion are characterised by a high variation in study designs and experimental parameters. Based on a summary of the existing protocols, the present review aimed to describe and discuss the parameters which must be carefully considered in erosion-abrasion research, especially when it is intended to simulate clinical conditions. Experimental characteristics and parameters were retrieved from a total of 42 in vitro and 20 in situ studies. The key experimental characteristics included parameters of erosion (duration and pH) and abrasion (duration, kinds of toothbrush and toothpaste, brushing force, and time point) as well as cofactors (e.g. dental hard tissue). The majority of studies used models with alternating erosion/abrasion treatments intended to simulate clinical conditions, while other studies exaggerated clinical conditions intentionally, often using only a single erosion/abrasion treatment. Both in vitro and in situ models shared a high level of standardisation, but several studies showed a trend to severe erosion (e.g. >5 min/cycle) or extensive brushing (e.g. >100 brushing strokes/cycle) at a high frequency and repetition rate. Thus, studies often tend to produce a higher amount of wear than in the clinical situation, especially as modifying biological factors (e.g. the dilution of the erosive solution by saliva and the protective effect of the pellicle) cannot be simulated adequately. With respect to the existing models, it seems advisable to diminish duration and frequency of erosion and abrasion to more realistic clinical conditions when the everyday situation is to be simulated. Experimental parameters must be chosen with care to ensure that the problem is investigated in an appropriate mode at standardised conditions and with adequate measuring systems to allow prediction of clinical outcomes. strokes/cycle) at a high frequency and repetition rate.

Karger AG, Basel In recent years, extensive research has been undertaken in order to gain a better insight into and understanding of the processes involved in the development of erosive tooth wear. Erosion, abrasion and attrition rarely act alone but interact with each other, and abrasion of erosively altered dental hard tissues is considered as the most import...
