Prefabricated blood vessels may revolutionize root canals

Root canals are used to save a tooth that has become infected or decayed, with over 15 million performed each year in the U.S.. However, this procedure can cause teeth to become to become brittle and susceptible to fracture over time. The procedure involves removing infected dental tissues and replacing them with synthetic biomaterials covered by a protective crown. Now researchers in Portland, Oregon, have developed a process by which they can engineer new blood vessels in teeth, creating better long-term outcomes. By removing the tooth’s blood and nerve supply it is without an biological response. Then can cause the tooth to be lost and a need of dentures or implants. The researchers used a 3D printing-inspired process, which was based on their previous work fabricating artificial capillaries, to create blood vessels in the lab. They placed a fiber mold made […]

Going to the Virtual Beach Improves Dental Experiences

For patients at a dental practice in  Devon, England, Virtual Reality encounters in the dental chair can result in demonstrably better experiences. A team of researchers at the Universities of Plymouth, Exeter and Birmingham worked with Torrington Dental Practice in Devon to find out whether virtual experiences could improve the patient’s experience during routine dental procedures such as teeth removal. Patients, who agreed to take part in the study were randomly allocated to one of three conditions: a) standard care , b) a virtual walk around Wembury beach in Devon or c) a walk around an anonymous virtual reality city. Results found that those who ‘walked’ around Wembury beach were less anxious, experienced less pain, and had more positive recollections of their treatment when compared to those in the standard care condition. These benefits were not found for those who walked […]

What You Eat Can Play A Role in Preventing Cancer

New research has shown that several natural compounds found in food, including turmeric, apple peels, and red grapes, could prevent the growth of prostate cancer, the most common cancer in U.S. men. The research uses a novel analytical approach to screen numerous plant-based chemicals instead of testing a single agent as many studies do, discovering specific combinations that shrink prostate cancer tumors. After screening a natural compound library, the researchers developed an unbiased look at combinations of nutrients that have a better effect on prostate cancer than existing drugs. The researchers were able to inhibit tumor growth in mice without any toxicity. During the past decade, other cancer research has shown that the chemicals found in foods such as turmeric, apple peels and green tea could be beneficial against cancer. These compounds reduce inflammation within the body and this reduction […]

Estrogen therapy can help reduce gum disease

Estrogen therapy has been credited with helping women manage a wide range of menopause-related issues, such as hot flashes, improving heart health, and maintaining sexual satisfaction. New research suggests that estrogen therapy used to treat osteoporosis can lead to healthier teeth and gums. During menopause estrogen levels reduce and women become more vulnerable to health issues such as loss of bone mineral density which can lead to osteoporosis. During menopause changes in oral health also are common as teeth and gums become more susceptible to disease, leading to inflammation, bleeding, pain, and potentially lost teeth. In the research, 492 postmenopausal Brazilian women aged 50 to 87 years, 113 in osteoporosis treatment and 379 not treated, were evaluated to determine whether osteoporosis treatment could help increase the bone mineral density in their jaws and improve oral health. The study found that […]

Bacterium goes from the mouth to the heart to cause disease

The human mouth can have more than 700 different species of bacteria. Under normal circumstances these microbes co-exist as part of our resident oral microbiota but when they spread to other tissues via the blood stream, the results can be catastrophic. Researchers from the University of Bristol have revealed a potentially key molecular process that occurs in the case of infective endocarditis, a type of cardiovascular disease in which bacteria cause unwanted blood clots to form on heart valves. If untreated, this condition is fatal and even with treatment, mortality rates are high. There are over 2,000 cases of infective endocarditis in the United Kingdom (UK) annually and the amount is rising. The research involved the use of the UK national synchrotron facility, Diamond Light Source. Using this giant X-ray microscope the team was able to visualise the structure and […]
