Some test surfaces were incorporated with hydrogen by cathodic polarization and/or acid etching with HCl/H2SO4. Nanoroughness (Sa) positively correlated with microbial adhesion. Biofilm accumulation was less pronounced on flat and grooved than on irregular surfaces. No significant association between hydrogen content or hydrophilicity of the surface and biofilm accumulation was observed. Nanoroughness (Aldosterone texture influence oral biofilm accumulation independent of surface chemistry and hydrophilicity. Surface hydrogen, which has previously been shown to promote fibroblast growth, does not affect biofilm formation. ""C. Chen1, L. Mau2 1Chi-Mei, Tainan, Taiwan2Chi-Mei Medical Center, Tainan, Taiwan Background Sufficient keratinized soft tissues are key for the long-term stability HCS assay of dental implants. Clinical studies have revealed that peri-implant gingival plaque index may be increased when there is lack of sufficient keratinized tissues. Both free gingival graft (FGG) and subepithelial connective tissue graft (SCTG) can be utilized for increasing the width of keratinized peri-implant soft tissues. However, there is a paucity of clinical studies that compare the clinical results of these two grafts. Aim/Hypothesis The aim of this study is to compare the clinical outcomes of free gingival graft and subepithelial connective tissue graft for increasing the keratinized peri-implant tissues. Material and methods A total of 13 patients with 27 implants with less than 2?mm keratinized tissues around implants were included in this study. 17 patients received free gingival graft and ten patients received subepithelial connective graft to augment the keratinized tissues. The width of the keratinized tissue of buccal site of implants were measured by periodontal probe at different timelines: before surgery (T0), right after surgery (T1), and crown delivery (T2). Mann�CWhitney MEK inhibitor test was used to compare the difference of these two groups. Results In the group of FGG, the average width of keratinized tissue was 0.38?+?0.6?mm, 5.09?+?1.95?mm, 4.88?+?2.06?mm at T0, T1, and T2 respectively. In the group of SCTG, the average width of keratinized tissue was 1.3?+?0.35?mm, 5.3?+?1.27?mm, 3.5?+?1.03?mm at T0, T1, and T2 respectively. The amount of increased width was 4.22?+?2.24?mm for FGG and 2.2?+?0.79?mm for SCTG. The difference was statistically significant (P?
