WELCOME to our lab

​The research of our lab focusses on understanding the etiology of caries and the process of dental wear. We cover a wide range of topics from oral food processing to the development of new diagnostic and treatment concepts in dentistry. To this end, we investigate dentin and enamel caries, the oral microbiome and wear surfaces. Furthermore, we measure the bonding between tooth, bone, dental materials and adjacent tissues applying 3D methods. We also develop mathematical models to simulate and link the measured 3D morphology to related disease patterns. The basic insights we gain this way, directly contribute to the development of novel treatment approaches in periodontal and endodontic dentistry.

Periodontology, Cariology, Endodontology

​Dental caries is the most prevalent disease worldwide. With this in mind, we develop new approaches for caries diagnostics and monitoring, and we test existing approaches for validity and reliability. We analyze and quantify the oral microbiome to detect the amount of the cariogenic biofilm and to develop new therapeutic approaches. In addition, we conduct research using ultra-fast laser surface modifications as a new promising treatment strategy. Furthermore, multidisciplinary dental care is an important research area to access oral health-related quality of life. Therefore, we pursue the approach of cross-sectional case studies in patients with chronical diseases (e. g. diabetes, severe heart failure, rheumatoid arthritis) to examine oral health, behavior and life quality. Moreover, we aim to develop concepts for dental and periodontal treatments.

Restorative and Adhesive Dentistry

Our goal is to develop efficient real-time assessments of adhesive-composite/ceramic restorations in frontal and cheek teeth to identify clinically relevant evaluation parameters. Thus, we conduct controlled clinical in-vitro as well as in-vivo trials to access the performance of adhesives in different application modes. Our expertise is the development and use of innovative quantitative 3D imaging techniques such as optical coherence tomography, µCT and 3D surface scanning. We visualize and measure failure of the composite structure and develop new clinical therapy concepts in prophylaxis.

Chewing Efficiency and Tooth Wear

The research area of 3D wear analyses is evolving on all scales, and our understanding of the multi-factorial wear process in mammal teeth (incl. humans) is increasing. Our lab aims to open up new research avenues to obtain a better understanding of the biomechanics and scaling of the multifaceted interactions taking place during comminution. We conduct artificial chewing simulations in human teeth in combination with mathematical modelling and actualistic experiments in selected mammalian taxa. Thus, we characterize the repetitive kinematics of the chewing process as well as the subsequent complex changes of the occlusal surface. Considering evolutionary perspectives, we aim to clarify the etiology of the microscopic short- and macroscopic long-time signatures.
