Influence of epigenetics on periodontitis and peri-implantitis pathogenesis

Periodontitis is a disease characterized by tooth-associated microbial biofilms that drive chronic inflammation and destruction of periodontal-supporting tissues. In some individuals, disease progression can lead to tooth loss. A similar condition can occur around dental implants in the form of peri-implantitis. The immune response to bacterial challenges is not only influenced by genetic factors, but also by environmental factors. Epigenetics involves the study of gene function independent of changes to the DNA sequence and its associated proteins, and represents a critical link between genetic and environmental factors. Epigenetic modifications have been shown to contribute to the progression of several diseases, including chronic inflammatory diseases like periodontitis and peri-implantitis. This review aims to present the latest findings on epigenetic influences on periodontitis and to discuss potential mechanisms that may influence peri-implantitis, given the paucity of information currently available.

Epigenetics-Shedding Light on the Path Ahead for Material Sciences

The harmonious regulation of bodily function is a necessity for healthy individuals. Looking from the viewpoint of material sciences, one can only marvel at the cellular factories, their renewal, and the overall control of messaging and control of responses. As aging progresses and/or pathologies arise, clinicians may be forced to look for replacement of organs/tissues with medical devices. Since all devices are tailored, a detailed understanding of developmental processes, including aberrant processes leading to pathologies, is crucial to provide clinicians with a suitable device. Although research in the field of epigenetics has produced effective therapeutics and diagnostic markers, our currently fragmented understanding of epigenetic processes as they relate to material development is inherently limited, with logical implications for the success of medical procedures. Here, we illustrate how material sciences for clinical applications, critically depend on all aspects of biomedical sciences, including the field of epigenetics.
