“…This finding was in agreement with a previous study 35) . In contrast to previous findings 36) , there was no significant difference in surface appearance and composition of composite resins before vs. after treatment with fluoride preparations. This may be due to the different application time between the previous and the present study (8 h vs. 3 min).…”

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.

“…The high reactivity of fluoride agents used in topical applications cause concern regarding the adverse effects on restorative materials (7). Acidulated phosphate fluoride creates superficial erosion on the outmost surface of composite resin (8,9) and glass-ionomer cement (10,11). Acidulated phosphate fluoride gel (1.23%) seems to be most effective at increasing fluoride release by restorative materials, compared to 1% neutral fluoride gel, 0.001% calcium fluoride, and 4% stannous fluoride (5,12,13).…”

“…Acidulated phosphate fluoride gel (1.23%) seems to be most effective at increasing fluoride release by restorative materials, compared to 1% neutral fluoride gel, 0.001% calcium fluoride, and 4% stannous fluoride (5,12,13). However, because of its deleterious effects on the surface roughness of restorative materials, the topical application of acidulated phosphate fluoride gel remains controversial (10,11). The aim of this study was to evaluate the topical application of acidulated phosphate fluoride on surface roughness of both dental enamel and different restorative materials.…”

Purpose: The aim of this study was to assess the influence of topical acidulated phosphate fluoride on the surface roughness of both human enamel and different restorative materials.Methods: Resin-modified glass ionomer (Vitremer -V), microhybrid composite resin with fluoride (Tetric Ceram -T), and nanofiller composite resin without fluoride (Z350 -Z) were evaluated. Acidulated phosphate fluoride (APF, 1.23%) was applied to half of the specimens (groups VF, TF, ZF and EF). Ten intact human third molars were used to obtain enamel specimens (E). Six experimental groups (n=10) and two control groups (n=10) were formed. The mean surface roughness (Ra) of both the restorative materials and enamel, with and without fluoride, was evaluated with a profilometer. Data were analyzed with an ANOVA, Tukey's test, Student's t-test, and Dunn-Bonferroni test at the 5% significance level.Results: The mean values of surface roughness, in micrometers, were as follows: Z=0.60; TF=1.00; ZF=1.05; VF=1.18; T=2.10; V=2.70; E=16.99; and EF=21.19. Both E and EF presented significantly higher surface roughness than the other experimental groups.Conclusion: It was concluded that APF increased the surface roughness of enamel and decreased the surface roughness of both resin-modified glass-ionomer cement and microhybrid composite resin with fluoride. The surface roughness of the nanofiller composite resin was not modified by APF.

“…Other studies carried out showed that neutral fluoride does not cause an increase in surface roughness [10,25,26]. This fact was related to the neutral pH value, which is unable to contribute to significant alterations in the topography of the surface [10].…”

OBJECTIvE: This study evaluated the surface roughness of a nanofilled composite resin submitted to different degrees of erosion and methods of control. METHODS: 120 cylindrical composite specimens (6×1.5 mm) were randomly divided into four groups, according to the surface protection against the erosive challenge [negative control, topical application of fluoride, glass-ionomer sealant, resin sealant]. After the application of the respective method, specimens were divided into three subgroups (n=10): a) absence of erosive challenge; b) 9 cycles of DES-RE; c) 18 cycles of DES-RE. Surface roughness (Ra, μm) was recorded and statistically analyzed (2-way Anova/Tukey). RESULTS: The glass-ionomer sealant exhibited less rough surfaces under all the conditions. However, the average roughness was significantly higher after 18 DES-RE cycles. CONCLUSION: Despite the potential shown by glass-ionomer sealant, it was concluded that no material prevented an increase in surface roughness of the nanofilled composite after an intense erosive challenge.Key words: Tooth wear; Fluorine compounds; Definitive dental restoration Efeito da erosão e de métodos para seu controle sobre a rugosidade superficial da resina composta RESUMO OBJETIvO: Este estudo avaliou a rugosidade superficial de uma resina composta nanoparticulada submetida a diferentes graus de erosão e a métodos para seu controle. MÉTODOS: 120 corpos de prova cilíndricos (6×1.5 mm) em resina composta foram aleatoriamente divididos em quatro grupos experimentais, de acordo com o método de proteção superficial [controle negativo, aplicação tópica de flúor, selante ionomérico, selante resinoso]. Após a aplicação dos respectivos métodos, os corpos de prova foram divididos em três subgrupos (n=10): a) ausência de exposição à solução simulada de ácido gástrico; b) 9 ciclos de DES-RE; c) 18 ciclos de DES-RE. valores da rugosidade superficial (Ra, μm) foram registrados e analisados estatisticamente (Anova 2-critérios/Tukey). RESULTADOS: O selante ionomérico promoveu superfícies menos rugosas, em todas as condições experimentais testadas. Porém, todas as médias de rugosidade ficaram significativamente mais altas após 18 ciclos de DES-RE. CONCLUSÃO: Apesar do potencial demonstrado pelo selante ionomérico, conclui-se que nenhum material foi capaz de evitar o aumento de rugosidade superficial da resina composta nanoparticuladas após a maior intensidade de desafio erosivo.
