Özet
The aim of this study was to analyze abutment surface roughness by Atomic force microscopy (AFM) and Scanning electron microscopy (SEM), comparing different abutment manufacturing materials/methods and evaluation of Streptococcus mutans and Candida albicans adhesion via microbiological analysis. The material/technique combinations used in the study were; Cr-Co Alloy (casting), Cr-Co Alloy (CAD-CAM milling), Titanium (CAD-CAM milling), Zirconia (CAD-CAM milling), Anodized Titanium (CAD-CAM milling), Laser Sintered Cr-Co Alloy, and factory stock Titanium abutments as control group. A total of 49 samples (7 per group, 5 mm x 2 mm) were analyzed using AFM and SEM. Surface characteristic values were recorded and statistically evaluated with Kruskal-Wallis and non-parametric tests. Each group had 3 samples inoculated with S. mutans and C. albicans, with microorganism counts recorded. The obtained data were recorded and statistically evaluated using ANOVA and Tukey HSD tests. Statistically significant differences (p<0.05) were found in surface roughness parameters (Ra, Rq, Rmax) among groups. Cr-Co Laser Sinter had the lowest Ra (0.004±0.001 μm), and Zirconia Milling had the highest (0.112±0.055 μm). S. mutans accumulated most in Zirconia Milling (5.87±0.08) and least in Milling Cr-Co (4.04±0.11). For C. albicans, highest accumulation was in Milling Ti Grade 5 Stock (6.41±0.03), and least in Milling Ti Grade 5 Anodization (6.13±0.03). The statistical significance of both surface roughness and microbial adhesion in each group can give information for clinicians in material selection according to the cases.
