“…Composite resins are more stable, nano‐sized and organized due to the material formulation and morphology of the filler particles. This allows them to have a higher inorganic volume and thus composites are less affected by acidic conditions (Attar, 2007; Candan & Ünal, 2021).…”

The aim of this study is to evaluate the microhardness, relative surface roughness, and elemental changes of resin‐based dental restorative materials (RDRMs) after gastric acid treatment. Five different RDRMs (Group 1 [Filtek Z550], Group 2 [Beautifil II], Group 3 [Vertise Flow], Group 4 [Dyract XP], Group 5 [Fuji II LC]) were used. Samples were formed by using plexiglass molds of 10 mm diameter and 2 mm thickness. A total of 50 samples (n = 10) for microhardness tests and a total of 15 samples (n = 3) for scanning electron microscopy (SEM)–energy dispersive X‐ray spectroscopy (EDX) analysis were prepared. All samples of each group were treated to gastric acid, simultaneously. A Vickers microhardness tester was used to evaluate the microhardness of the upper surfaces of each sample. SEM–EDX system was used for microstructure and elemental composition detection. The SEM–EDX, microhardness and relative surface roughness analysis were made prior to treatment in gastric acid for 14 days and analysis were repeated on the 14th day. As the difference in the microhardness values of RDRMs was compared, the time‐dependent variation in all RDRMs was found to be statistically significant. It was observed that a drastic decrease in microhardness values was in Beautifil II, Filtek Z550, Vertise Flow, Fuji II LC, and Dyract XP, respectively. Average decrease rate of microhardness values compared to the initial state can be listed from high to low as Beautifil II (%35.72), Vertise Flow (% 28.88), Fuji II LC (% 21.09), Dyract XP (%17.60), and Filtek Z550 (% 16.58). As a result, in in‐vitro conditions gastric acid decreased microhardness while increasing the relative surface roughness of RDRMs.

“…AFM allows a deep analysis of the surface structure of some dental materials (Tomoaia‐Cotisel et al, 2008: Candan & Ünal, 2021). The most irregular surface presented by Vitremer™ could be because of a large number of porosities on its surface, which are probably caused by the incorporation of air bubbles with the conventional powder/liquid mixture (De Paula et al, 2011).…”

“…The surface morphology of Ketac™ N100 was smother and homogeneous than Vitremer™. Candan & Ünal, 2021 examinated the surface roughness of one RMGIC and they found that it showed higher surface roughness by large and irregular fillers content compared to other dental restorative materials (Candan & Ünal, 2021). In this study, the surface topography of two material was different, therefore, the second hypothesis was rejected.…”

“…The fluoride release varies between different restorative materials, as well as, within different brands and may be affected by the formation of complex fluoride compounds, their interaction with polyacrylic acid, and by the type and amount of resin used for the photochemical polymerization reaction (Wiegand, Buchalla, & Attin, 2007). AFM allows a deep analysis of the surface structure of some dental materials (Tomoaia-Cotisel et al, 2008: Candan & Ünal, 2021.

Reinforced glass ionomer cements have been widely used in pediatric dentistry to prevent dental caries. However, the influence of biomaterial light-curing and its anticariogenic effects remain unclear. This study evaluates the influence of the lightcuring time on fluoride release, surface topography, and bacterial adhesion in two types of resin-modified glass ionomer cements (RMGICs). One hundred disks were made, and samples were divided into two groups (n = 50 per group), according to each dental material (Vitremer™ and Ketac™ N100), and also divided into different light-cured times (10, 20, 30, 40, and 60 s). They were placed in phosphate-buffered saline solution (PBS) to measure the fluoride release. Subsequently, an independent sample of RMGICs per group was examined using atomic force microscopy (AFM).Four disks per group were incubated in a brain heart infusion (BHI) medium that was inoculated with Streptococcus mutans GS5 to evaluate the bacterial adhesion by 3-4,[5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide cell viability assay (MTT assay). The fluoride release was related to the light-curing time and gradually decreased as the light-curing time increased in both materials. Surface topography in Vitremer™ presents more irregular surfaces than Ketac™ N100. For S. mutans adhesion, the smallest number of cells per milliliter (cell/ml) was found at 40 s for Vitremer™ and at 30 s for Ketac™ N100. Thus, the shorter light-curing times allowed for major fluoride release in both materials. However, the RMGICs showed different patterns of bacterial adhesion according to the brand and light-curing time.

“…13 Salbutamol sulfate also has an effect on the surface of the restoration material, increasing discoloration and surface roughness caused by the formation of matrix pellicles which may cause the oral cavity to become acidic. 13,14,15 A roughened surface may cause adhesion of bacteria to restorative material. 15 Therefore, restorative materials must be well finished and polished to provide ideal surface characteristics and esthetics.…”

Bioactive composite resin is the newest restorative resin material which has good mechanical and aesthetic properties. In the oral cavity, the restoration is degraded due to exposure to acids, one of which is exposure to asthma drugs. Properties of composite resins that can be affected by degradation include surface roughness. This study aims to analyze salbutamol sulfate exposure to the surface roughness of bioactive resins. The research method used was pure experimental design with post test-only with control design. The study used 39 specimens of bioactive resin (8 mm in diameter and 2 mm in thickness), divided into 3 treatment groups, namely the 400µg salbutamol sulfate exposure group, the 800µg salbutamol sulfate exposure group and the artificial saliva control group with treatment every 24 hours for 7 days, subsequently the specimens are tested with the surface roughness of the composite resin using a surface roughness tester. The highest surface roughness value was found in the 800µg group (8.23 ± 0.98 µm), followed by 400 µg group (5.43 ± 1.16 µm) and the lowest in the artificial saliva group (2.63 ± 0.82 µm). There were significant differences in all treatment groups. The exposure of salbutamol sulfate affects the surface roughness of the bioactive composite resin, a higher number of exposure doses indicates a higher surface roughness value.Keywords: bioactive composite resins, salbutamol sulfate, surface roughness
