“…Different resistance of different types of llings can be assumed [10]. From amalgam, which is assumed to be completely inert to acids, through composite materials, which depend on the matrix and ller used, to glass ionomer cements, which due to their remineralization potential may be prone to rapid demineralization [11,12].…”

Erosive tooth wear, that is characterized like irreversible loss of hard dental tissues due to influence of external and internal acids of nonbacterial origin, is one of the most common damage of a tooth surface. Erosive factors also affect the surface of dental reconstruction materials that ideally should be resistant against them. Dental filling materials designed for this purpose must be able to withstand these effects in a comparable or even better way than enamel. In our in vitro study we investigated using the nanoindentation the hardness of currently available dental filling materials (dental composite resin, self curing and dual cures glassionomer cement, dental amalgam) before and after erosive attacks (exposure to Coca Cola for 5 min and 14 days) and consequently compare it with them of human dental enamel. Furtermore we analised the surface topography of the samples before and after acidic exposure by confocal laser scanning microscope. In our experiments the filling materials were affected by the acidic environment only minimally in comparison with hard dental tissues. We confirmed the fact that dental amalgam is still the most mechanically and chemically resistant filling material. Both GIC materials showed the worst resistance against acidic conditions and higher surface roughness even before exposure. We also declared excellent withstanding of resin composite materials against acidic conditions that was even better than natural enamel. Furthermore by CLSM was detected almost unaltered surface of these filling materials. This fact as well as adhesive properties of resin composites allow to assume that this material could be the most suitable material for dental erosion reconstruction.

The aim of the present study was to assess by atomic force microscopy (AFM) the surface roughness of a traditional glass ionomer cement- GIC (Fuji IX GP, GC Corporation, Tokyo, Japan) and a resin modified glass ionomer cement- RMGIC (Vitremer, 3M ESPE, St. Paul, MN, USA) after different immersion regimes on some acidic drinks. Sixteen cylindrical samples having the height of 5 mm and the thickness of 2 mm were obtained from each material and they were divided into two groups: Group I (Fuji IX samples) and Group II (Vitremer samples). Specimens of each group were then randomly divided into 4 subgroups: subgroup A (control)—15 samples were kept in artificial saliva and in the other three subgroups, each having 15 samples the samples were immersed in Coca-Cola (subgroup B), Cappy lemonade and mint (subgroup C) and Fuzetea (subgroup D) for 7 days (subgroups A1–D1), 14 days (subgroups A2–D2), and 21 days (subgroups A3–D3). AFM qualitative and quantitative surface evaluation (mean value of surface roughness parameter, Sa) of each sample was performed. The highest surface roughness was determined when both materials were submerged 14 days in acidic drinks. Traditional GIC was more affected by acidic environment when comparing to RMGIC.

Úvod a cíl: Erozivně-abrazivní defekty tvrdých zubních tkání jsou vedle zubního kazu jednou z nejrozšířenějších patologií zubů. Dentální výplňové materiály určené k opravě těchto defektů musí být schopny odolat vlivům opotřebení -tedy erozi a abrazi -srovnatelně nebo lépe než sklovina, kterou nahrazují. Studie je zaměřena na zjištění povrchových změn výplňových materiálů různých kategorií po vystavení kyselému pH. Cílem je ověřit, že výplňové materiály odolají kyselinám lépe než zubní sklovina. Metodika: Vzorky byly ponořeny do Coca-Coly (pH 2,4) na pět minut a pro názornost erozivního procesu také po dobu 14 dnů. Při zkoumání vzorků byla použita obrazová analýza pomocí konfokálního laserového skenovacího mikroskopu. Byly také vyhodnoceny změny v tvrdosti povrchu pomocí nanoindentace a výsledky byly porovnány se sklovinou. Výsledky: Výplňové materiály, na rozdíl od skloviny, odolaly krátkodobé expozici bez signifikantních změn tvrdosti i vzhledu. Byly však pozorovány mikroskopické i makroskopické změny při expozici dlouhodobé. Tyto změny byly nejvíce patrné u skupiny skloionomerních výplňových materiálů. Závěr: Pozorování jasně prokázalo výrazně vyšší odolnost výplňových materiálů vůči kyselému prostředí, než jakou vykazuje sklovina.
