New research into oral microbiome may help reverse periodontitis

AUSTIN, Texas, USA: Studies on the human microbiome have shown that shifts in oral microbiota are associated with a number of diseases, including obesity, Crohn’s disease, diabetes and periodontitis. Now, U.S. scientists have found that oral bacteria act differently in diseased patients compared with healthy individuals. They believe that the findings could be used to develop methods to prevent or even reverse diseases such as periodontal disease. Although it is known that the composition of the microbiome changes during the transition from health to disease, it is still unclear how specific activities of different members of the microbial community affect diseases. In order to understand how different bacteria act in healthy and diseased individuals, researchers at the University of Texas at Austin examined periodontal plaque samples from ten patients from Izmir in Turkey with aggressive periodontitis. Using supercomputers, the researchers compared the expression of 160,000 genes in healthy and diseased periodontal communities and found that these communities show defined differences in metabolism. “In other words, a species of bacteria that ate one thing, such as fructose, can switch to a different kind of sugar to feed on if diseased,” explained Dr. Marvin Whiteley, professor of molecular biosciences at the university. A major question concerning the mechanism underlying the

TOKYO, Japan: The results of a recently published study have shown that ozone nano-bubble water (NBW3) is very effective against two bacteria that cause periodontitis. The researchers believe that this new antimicrobial agent could be used in the development of new therapies for the inflammatory disease, which affects 15 to 20 per cent of middle-aged adults in its severest form worldwide. In in vitro experiments, researchers at Tokyo Medical and Dental University and the National Institute of Advanced Industrial Science and Technology in Japan tested the effectiveness of NBW3 against Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans. They found that the levels of both bacteria dropped to below the lower limit of detection after only 30 seconds of exposure. In addition, they observed that NBW3 had no significant impact on human oral tissue. Using an in vitro human oral tissue model, composed of human-derived epithelial cells, they found only minor decreases in the viability of cells after 24 hours of exposure. Such models are used to test the toxicity and irritation potential of new dental materials and oral care products. According to the researchers, they are more predictive of human responses and more clinically relevant than are animal and monolayer cell culture test systems. Conventional antibiotic therapies for treating periodontitis hold the risk of sever

Dental implant surgical placement means placement of foreign bodies in the oral region, in order to provide better and more successful prosthetic rehabilitation. To date, the implants used extensively as a variety of materials with more or less success, since it is the body sooner or later rejected. How does dental implant looks like? Based on current knowledge, it can be said that metals such as stainless steel, chromium-cobalt-molybdenum alloys, precious metals and many polymers, bone tissue can be tolerated but not integrated. However, titanium, tantalum, niobium and others, like aluminum oxide ceramics, which are described as almost bioinert may be osteointegrated under certain conditions. Our clinic Eurodent in Belgrade, Serbia, guarantee the safe and secure implant surgery, will provide you a more beautiful smile and allow you to save money, because of our affordable services at low cost implants. You can see it on presented picture how does it looks like:
