The attachment of implants rely on bone and soft tissue biocompatibility.
The aim was to investigate the effect of fluoride modified metallic
titanium (Ti) surfaces (Ti-F) on proliferation and differentiation of human
gingival fibroblasts (HGF).
HGF cells were exposed to hydrofluoric acid (HF) modified Ti coins (Ti-F)
for 1, 3, 7, 14 and 21d, and untreated coins were used as controls.
A 5-6 fold increase in the proliferation of HGF on Ti-F compared to Ti
surfaces was observed. Enhanced gene expression of IL-6 and OPG was
found at 7 d. Increased levels of sclerostin, IL- 6 and OPG in the media
from HGF cultured on Ti-F coins were found compared to controls.
Our results confirm that HF modified surface may indirectly enhance the
firm attachment of implant surface to junction epithelium, soft tissue
epithelium, which would give protection for underlying osseous
structures making osseointegration of the dental implant possible.

Objectives
The aim of the study was to examine surface nanoroughness, texture and chemistry of dental implant abutment and to investigate how these parameters influence oral biofilm formation in healthy subjects.
Materials and methods
Eight different nanorough TiZr surfaces were produced by polishing, machining, cathodic polarization and acid etching. Surface topography was examined using field emission scanning electron microscope and a blue light laser profilometer. Surface chemistry was analyzed by secondary ion mass spectrometry and X-ray photoelectron spectroscopy. Surface hydrophilicity was tested by measuring contact angle on the surfaces. A human in vivo study using a splint model was employed to evaluate oral biofilm accumulation on these surfaces.
Results
Different surface textures (flat, grooved and irregular) were created with nanoroughness from 29 to 214 nm. 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.
Conclusions
Nanoroughness (< 214 nm) and surface 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

Abstract
Objective
The aim of the study was to investigate solely the effect of fluoride on the surface chemistry of polycrystalline ceramic titanium dioxide (TiO2) and metallic titanium (Ti) and its effect on proliferation and differentiation of primary human osteoblasts (NHO).
Materials and methods
The NHO cells were exposed to fluoride-modified and unmodified samples for 1, 3, 7, 14 and 21 days. The fluoride effect on the mRNA expression was quantified and measured. The secretion of cytokines and interleukins in the cell culture medium was measured by Luminex, gene expression by RT-PCR, and compared with untreated controls. The effect on cell growth after 1 and 3 days in culture was measured using [3H]-thymidine incorporation. Fluoride release was measured using an ion-selective electrode. The surfaces were examined by X-ray photoelectron spectroscopy and profilometry.
Results
The fluoride release study detected that fluoride content easily washed off in TiO2 coins when compared with Ti coins. No increase in cell proliferation was found among fluoride-modified TiO2 surfaces compared with controls, except for washed Ti coins with fluoride modification. The cell differentiation with regard to gene expression showed no significant differences in both fluoride-modified and unmodified samples and less effect on protein release for all groups.
Conclusions
The fluoride from hydrofluoric acid treatment on Ti and TiO2 surfaces gave no specific effect on primary human osteoblast cells. The study indicates that the released fluoride is not the unique factor for the bioactivity of Ti and TiO2 surfaces.

Titanium oxide (TiO2) scaffolds have previously been reported to exhibit very low mechanical strength. However, we have been able to produce a scaffold that features a high interconnectivity, a porosity of 91% and a compressive strength above 1.2 MPa. This study analysed the in vivo performance of the porous TiO2 scaffolds in a peri-implant cortical defect model in the rabbit. After 8 weeks of healing, morphological microCT analyses of the defects treated with the TiO2 scaffolds had significantly higher bone volume, bone surface and bone surface to volume ratio when compared to sham, both in the cortical and bone marrow compartment. No adverse effects, i.e. tissue necrosis or inflammation as measured by LDH activity and real-time RT-PCR analysis were observed. Moreover, the scaffold did not hinder bone growth onto the adjacent cortical titanium implant. Histology clearly demonstrated new bone formation in the cortical sections of the defects and presence of newly formed bone in close proximity to the scaffold surface and the surface of the adjacent Ti implant. Bone to material contact between the newly formed bone and the scaffold was observed in the histological sections. Islets of new bone were also present in the marrow compartment albeit in scarce amounts. In conclusion, the present investigation demonstrates that TiO2 scaffolds osseointegrate well and is a suitable scaffold for peri-implant bone healing and growth.
