“…Quantitative measurement of surface topography can be obtained using profilometry (Arabaci et al, ; Watanabe et al, ); or qualitative methods, such as scanning electron microscopy (Naseri et al, 2017; Zare et al 2018, Antonson et al, 2011, Erdemir et al, 2012) and atomic force microscopy (AFM) (Salerno et al, , Lainović, Blažić, Vilotić, & Kakaš, , Ţălu , Lainović et al, ]. In these studies, average surface roughness ( S a ) and root mean square ( S q ) were used to quantify morphological changes (Giacomelli et al, ; Janus, Fauxpoint, Arntz, Pelletier, & Etienne, ; Kakaboura, Fragouli, Rahiotis, & Silikas, ).…”

The objective of this study was to evaluate the effect of two photoactivation modes of dental LED light‐curing unit (LCUs) (conventional and “Soft Start” mode) on surface texture parameters of two dental resin‐based nanocomposites. LED LCUs were considered as standard light‐curing devices in contemporary dental practice. Atomic force microscopy (AFM) was applied to investigate surface morphology on 90 × 90 μm2 scanning area through 2D multifractal detrended fluctuation analysis with computational algorithms basis. In order to compare 3D surface roughness at nanometer scale, singularity spectrum f[α] was used which characterize local scale properties of multifractal nature of samples. The results confirmed that larger spectrum width Δα (Δα = αmax − αmin) of f(α) is associated with non‐uniform surface morphology. Moreover, materials whose polymerization was photoactivated by the “soft start” polymerization mode, showed better quality of the surface microstructure with lower values of AFM surface texture parameters.

“…In order to preserve the aesthetic features of the tooth to be restored, it is critical to take into account the surface characteristics of restorative materials such as surface roughness, gloss, and colour stability (Kumari et al, 2015, Lainovic et al, 2014, Rocha et al, 2017).…”

“…In order to maintain or improve the aesthetic appearance of a restorative material, it is essential that the surface roughness is equal to or less than the roughness of tooth enamel in occlusal contact areas (Ferreira et al, 2015, Lainovic et al, 2014). Thus, the surface treatment with a suitable finishing and polishing technique is considered a critical procedure in order to achieve a favourable aesthetic result and to increase the longevity of the tooth restoration (Janus et al, 2010, Jefferies, 2007, Yildiz et al, 2015).…”

“…Despite numerous works of various aspects of resin‐based composites, their three‐dimensional (3‐D) topography has rarely been studied (Dietz et al ., ; Lainović et al ., ; Ţălu et al ., ,b). Surface topography determines the behaviour of the materials at surface–environment interface, and serves as a keeper of the bulk material integrity in certain surrounding conditions (Brushan, ).…”

The aim of this study was to analyse the influence of the artificial saliva on a three-dimensional (3-D) surface texture of contemporary dental composites. The representatives of four composites types were tested: nanofilled (Filtek Ultimate Body, FUB), nanohybrid (Filtek Z550, FZ550), microfilled (Gradia Direct, GD) and microhybrid (Filtek Z250, FZ250). The specimens were polymerised and polished by the multistep protocol (SuperSnap, Shofu). Their surface was examined, before and after 3 weeks' exposure to artificial saliva storage. The surface texture was analysed using the atomic force microscope (AFM). The obtained images were processed to calculate the areal autocorrelation function (AACF), anisotropy ratio S (texture aspect ratio), and structure function (SF). The log-log plots of SF were used to calculate fractal properties, such as fractal dimension D, and pseudo-topothesy K. The analysis showed changes in surface anisotropy ratio S values, which became higher, whereas the S roughness (root-mean-square) reduced after the artificial saliva storage. All the samples exhibited bifractal structure before the saliva treatment, but only half of them remained bifractal afterwards (GD, FZ250), whereas the other half turned into a monofractal (FUB, FZ550). The cube-count fractal dimension D was found to be material- and treatment-insensitive.
