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 helps ward off cancer. Those with chronic inflammation have a higher cancer risk because of damage to normal cells. The researchers tested 142 natural compounds on mouse and human cell lines to see which inhibited prostate cancer cell growth when administered alone or in combination with another nutrient. The most promising active ingredients were tested on model animals. The researchers […]

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 the rate of occurrence of severe periodontitis was 44% lower in the postmenopausal osteoporosis-treatment group than in the untreated group. Treatment consisted of systemic estrogen alone or estrogen plus progestin, in addition to calcium and vitamin D supplements, for at least six months. As such, estrogen therapy may also prevent the worsening of tooth and gum disease. All women, but […]

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 dynamics of a protein called CshA which was believed to play an important role in targeting the oral bacterium Streptococcus gordonii to the tissues of the heart. The researchers were intrigued to find that CshA acts as a ‘molecular lasso’ to enable S. gordonii to bind to the surface of human cells. Such adhesive interactions are critical first steps in […]

Method to Reduce Dental Implant Failure

Fifteen million Americans have crown or bridge replacements and three million have dental implants. Dental implants can be successful for many patients; however, five to 10 per cent of all dental implants fail. The reasons for this failure are mechanical problems, poor connection to the implanted bones, infection or rejection. When failure occurs the dental implant needs to be removed. The main reason for dental implant failure is periimplantitis. This destructive inflammatory process affects the soft and hard tissues surrounding dental implants. When pathogenic microbes in the mouth and oral cavity develop into biofilms, periimplantitis develop on dental implants. A research team from the School of Biological Sciences, Peninsula Schools of Medicine and Dentistry and the School of Engineering at the University of Plymouth, have joined forces to develop and evaluate the effectiveness of a new nanocoating for dental implants to reduce the risk of periimplantitis. The results are published in the journal Nanotoxicology. The research team created a new approach using a combination of silver, titanium oxide and hydroxyapatite nanocoatings. The combination to the surface of titanium alloy implants successfully inhibited bacterial growth and reduced the formation of bacterial biofilm on the surface of the implants by 97.5 per […]

Filing Billing for Dentists to Help Patients

An interesting article titled “You want me to do what?” written by Douglas Auld appears in the March 2016 issue of JADA. The article discusses a patient who has an an abscess on a mandibular right third molar which requires extraction. The treatment was done in December and the patient had already used their full benefits from their dental insurance for the year. So the patient suggested to the dentist to bill for the extraction in January and also suggested to file it as a surgical extraction and apply the difference to his balance. The article asks if it is ethical for dentists to do any of this. The article states that a dentist has a duty to communicate truthfully with third parties. It says “A dentist who submits a claim form to a third party reporting incorrect treatment dates for the purpose of assisting a patient in obtaining benefits under a dental plan, which benefits would otherwise be disallowed, is engaged in making an unethical, false or misleading representation to such third party.” Therefore the dentist should file the claim with the correct date of service or wait until January to perform the treatment. The article says “A dentist who incorrectly describes on […]
