Microstructure, micromorphology, and fractal geometry of hard dental tissues: Evaluation of atomic force microscopy images

Abstract

Determining surface topography of different tissues of the molar tooth with novel analytical methods has opened new horizons in dental surface measurements which characterize tooth surface quality in dentistry. Studying surface topological measurements and comparing surface morphology of hard tissue of the molar tooth are the ultimate goals of the present study. Ten molar teeth have been chosen for investigating their surface characteristics through image processing techniques. The power spectral density (PSD) and fast Fourier transform algorithms of every molar tooth containing enamel, dentin, and cementum have determined that the characterization of surface profiles is possible. As can be seen, PSD along with fractal dimensions leads to good results for teeth surface topography. Moreover, PSD angular plot assures appropriate description of surface.

The electrophoretic deposition of TiB2 nanoparticles produced by pulsed laser ablation: Case study on microstructural features and micromorphology properties

“…Various studies have been performed over the last decades about the three dimensional (3D) microtexture of thin film surfaces. These analyses extract a lot of information about the topography and analyze the surface of thin films quantitatively (Nezafat et al, 2019a; Solaymani et al, 2021; Ţălu et al, 2018). The stereometric (Mozaffari et al, 2020; Sobola et al, 2017; Solaymani et al, 2020) data as well as multifractal (Fattahi et al, 2020; Ţălu et al, 2017; Ţălu et al, 2020) and fractal (Nezafat et al, 2019b; Ţălu et al, 2018) analysis are able to characterize the microtexture and particular morphological characteristics of the 3D surface.…”

Atomic force microscopy studies of enamel, inner enamel, dentin, and cementum in canine teeth

“…Despite the complex and irregular bio‐structure and fine anatomic details demonstrated by 3‐D morphology, the tooth surface can be analyzed stereometrically (Sharma et al, 2010; Ţălu, Contreras‐Bulnes, Morozov, Rodríguez‐Vilchis, & Montoya‐Ayala, 2016), or applying fractal (Hara, Livengood, Lippert, Eckert, & Ungar, 2016; Solaymani et al, 2018; Solaymani et al, 2018) and multifractal (Morozov et al, 2013; Ţălu et al, 2016) analyses of AFM micrograph samples (Dallaeva et al, 2015; Nezafat et al, 2019a, 2019b).…”

The effect of deposition times in DC‐magnetron sputtering on micromorphology of TiO2 thin films

“…In order to visualize surface morphology, the evaluation of surfaces in three dimensions is necessary. AFM analysis makes this process possible due to its ability in creating high resolution images in all three axes, and, that is why, it is used in many fields of science, especially those that require the highest precision, accuracy, and details in the data acquisition process (Mozaffari et al, 2020; Nezafat et al, 2019; Ţǎlu, Stach, Valedbagi, Elahi, & Bavadi, 2015). Theoretical and numerical tools such as surface modification and micromorphology can enhance product quality by improving optical, chemical, and physical properties of samples (Fattakhova‐Rohlfing, Zaleska, & Bein, 2014).…”
