Research to examine possible links between periodontal disease and oral cancer
Source: eu.dental-tribune.com Author: Dental Tribune International staff As worldwide oral cancer rates continue to climb, our understanding of what causes the disease to occur, thankfully, also continues to grow. Tobacco use and excessive alcohol consumption have been established as primary risk factors, and researchers are now investigating another potential source for this condition: the bacteria that cause periodontal disease. The research is being led by Dr Louise Belfield, a lecturer in biomedical science at the University of Plymouth’s Peninsula Dental School, in collaboration with the university’s Institute of Translational and Stratified Medicine. Since cancer requires blood vessels to grow and metastasise, the research team is planning to build on existing evidence that shows how certain bacteria that cause periodontal disease are linked to angiogenesis. To do so, the research team will develop miniature tumours and blood vessels in a laboratory setting, adding the bacteria with the aim of clarifying how they function and what effect they have on the blood vessels. According to a press release from the university, if the research ascertains that the bacteria make the blood vessels grow more rapidly and similarly to those associated with tumours and identifies the process by which this is achieved, the results could form the basis of a new screening programme to detect oral cancer risk earlier. This would make it possible to begin treatment in a more timely manner. “We know that tumours in the mouth, unlike many other tumours, are in constant contact with bacteria, but we don’t know [...]
