Abstract of the dataset | The paper describes the development of a flow chamber model for the assessment of cell adhesion strength under variable shear stress, her shown for human gingival cells to test cell adhesion phenomena under mechanical stress. This model is then applied in proof of principle experiments to two surface modification types that have promising surface properties and are intended for the application in dental Two types of datasets are provided: (1) raw image sets comprising combinations of microscopy images, each accompanied by corresponding metadata, and (2) processed datasets derived from individual physico-chemical measurements or on raw images. The 2nd datatype includes either basic statistical analyses—such as the calculation of means, standard deviations, standard errors, and associated statistical tests—or more advanced analyses performed through automated image processing. For the latter, the figures presented in the publication represent the results of image analyses conducted using custom-optimized macros. Each archive for each individual figure also contains the raw images, a data analysis file that compiles the raw output data generated by ImageJ, output of statistical tests as well as the respective final graphical representation. A detailed description of the data structure and image analysis workflow is provided in the accompanying README file. The macros used for image processing are published in Supplement 2 of the original publication. However, for convenience, they are also included here as standalone text files alongside a detailed instruction how to use the macros, assembled in the respective archive folder. | |

Project abstract | Dental implants are a well established treatment option for the replacement of missing teeth. However, the soft tissue in the area of the abutment is susceptible to peri-implant mucositis caused by an adherent biofilm. As the inflammatory process progresses, peri-implantitis is associated with bone resorption and loss of osseointegration. In the transition area to the oral cavity, easy-to-clean surfaces should be sought to avoid matured biofilms. At the same time, a stable attachment of the soft tissue to the abutment prevents the penetration of pathogenic bacteria into the periodontium. The aim of the proposed project is to gain a comprehensive understanding of the mutual influences of texturing, surface energy and surface chemistry aiming for superior properties of titanium surfaces with respect to biofilm formation as well as soft tissue sealing. For this purpose, specifically functionalized nanodiamonds, which are modified both in terms of their size and their surface chemistry, are partially integrated into titanium surfaces by anodic thickening of the oxide layers. The microbial and cell biological characterization is carried out under static as well as dynamic conditions with appropriate conditioning of the surfaces in order to simulate the conditions in the oral cavity as well as preventive cleaning measures. Using statistical design of experiments, matrices with different combinations of surface energy, surface chemistry and topography are generated and analyzed by multiple regression with respect to the parameters i) number of focal complexes, ii) cell size and iii) fibrin reorganization for adhesion of gingival fibroblasts or iv) live bacteria counts and v) biofilm mass for primary adhesion of relevant oral bacteria in mono or di-species cultures. Promising surface conditions will then be characterized in complex multi-species biofilm models and with regard to the barrier function of adherent gingival cells and the functionality of selected aspects of the human immune defense. Based on these mutually complementary findings, the comprehensive assessment of the influence of nanostructure parameters is possible for surfaces with identical surface chemistry and largely constant surface energy. It is expected that synergistic effects of nanostructures and chemical functionalization can be identified by the analysis of a variety of possible combinations. The utilization of nanodiamonds in the modification of titanium surfaces provides the opportunity for future modular systems with arbitrarily combinable properties or additional specific functionalization. | |
