This study aimed to evaluate the cytotoxic effects of different topical hyaluronic acid-based gels on human gingival fibroblasts and oral bacteria. Four hyaluronate - Bexident® Aftas (BA), GUM® AftaClear (AfC), Gengigel®(G), Aloclair® Plus (AlC) a chlorhexidine gel Bexident®Gums(BG) were selected. Human (HGF) seeded in 48-well plates with gel/culture medium concentrations (v/v%) cell viability was evaluated at 1 3 days culture. Cell morphology assessed, alterations graded according ISO...
The aim of this study was to evaluate gingival fibroblasts and human osteoblasts’ response textured Nd:YAG laser microgrooves, with different dimensions, on zirconia implant surfaces. A total 60 disks (8 mm in diameter 2 thickness) were produced divided between four groups (N = 15): three laser-textured (widths 125.07 ± 5.29 μm 45.36 2.37 depth values from 50.54 2.48 23.01 3.79 μm) a control group without treatment. Human osteoblasts cultured these surfaces for 14 days. FEG-SEM (Field...
Background and Aim: Yttria-stabilized tetragonal Zirconia polycrystal (Y-TZP) has emerged in dentistry as a promising material for various applications, such dental implant surfaces. Nd:YAG laser surface treatments been considered an innovative texturing technique to improve roughness early osteointegration. However, the optimal parameters texture
