Vaping e-cigarettes could increase the risk of oral disease, study finds

Source: technology.inquirer.net Author: staff New American research has found that individuals who use e-cigarettes could be at risk of developing oral diseases in the future, which could range from gum disease to cancer. Carried out by researchers at The Ohio State University, the new study looked at a group of 123 people with no signs of oral disease. The group included 25 smokers, 25 non-smokers, 20 e-cigarette users, 25 former tobacco smokers who used e-cigarettes and 28 people who smoked both tobacco cigarettes and e-cigarettes. The team collected plaque samples taken from under the gums of the participants to analyze the bacteria in this part of the mouth; bacteria here is the last line of defense against disease as it is the least likely to be disrupted by environmental changes in the mouth, such as food, toothpaste and tobacco. The researchers then carried out DNA deep sequencing of the bacteria’s genomes to identify what types of microbes were living in participants’ mouths and what their functions were. The findings, published in the journal Science Advances, showed that although the e-cigarette users didn’t have signs of active disease, their oral bacteria composition was similar to that of people with severe periodontitis, a severe gum infection that can lead to health problems such as tooth loss, and, if left untreated, is a risk factor for serious conditions such as heart and lung disease. The effect of e-cigarette smoking was also seen with or without nicotine, which the researchers say suggests that it [...]

Five game changers: will they alter the course of dental hygiene treatment?

Source: www.rdhmag.com Author: Karen Davis, RDH, BSDH With the beginning of a new year, clinicians may be wondering what new technologies or services they should consider. As I reflected on this, it led me to consider what has the potential to become game changers for dental hygienists. I immediately considered the integration of laser technology, sharpen-free instruments, ergonomic operator chairs, CAMBRA, adjunctive devices for caries detection, and oral cancer screenings. Within minutes, I had a list of about 25 technologies and services that have completely altered how I practice dental hygiene from the day I started in 1979. So I decided to feature a few technologies I believe are underutilized or, in a few cases, even unknown by clinicians who have the potential to substantially alter patient care. Automated and unassisted periodontal charting In the world of dental hygiene, having another person enter data into the computer or record periodontal data is either a luxury or is uncommon. Dental hygienists everywhere seem caught in the time trap of laboriously entering the data or, in many cases, settling for spot probing and incomplete data collection. But automated technologies to collect and enter the data unassisted have been available to dental hygienists for decades, and when integrated, have the potential to help diagnose periodontal diseases in the earliest possible stages. Dental R.A.T. (Remote Assisted Technology) is a foot-operated device that enables the clinician to enter periodontal data unassisted using hand-eye-foot coordination. It integrates to major software programs, automatically entering the data into [...]

Colgate Total ingredient linked to hormones, cancer spotlights FDA Process

Source: www.bloomberg.com Author: Tiffany Kary The chemical triclosan has been linked to cancer-cell growth and disrupted development in animals. Regulators are reviewing whether it’s safe to put in soap, cutting boards and toys. Consumer companies are phasing it out. Minnesota voted in May to ban it in many products. At the same time, millions of Americans are putting it in their mouths every day, by way of a top-selling toothpaste that uses the antibacterial chemical to head off gum disease - Colgate-Palmolive Co.’s Total. Total is safe, Colgate says, citing the rigorous Food and Drug Administration process that led to the toothpaste’s 1997 approval as an over-the-counter drug. A closer look at that application process, however, reveals that some of the scientific findings Colgate put forward to establish triclosan’s safety in toothpaste weren’t black and white -- and weren’t, until this year, available to the public. Colgate’s Total application included 35 pages summarizing toxicology studies on triclosan, which the FDA withheld from view. The agency released the pages earlier this year in response to a lawsuit over a Freedom of Information Act request. Later, following inquiries from Bloomberg News, the FDA put the pages on its website. The pages show how even with one of the U.S.’s most stringent regulatory processes -- FDA approval of a new drug -- the government relies on company-backed science to show products are safe and effective. The recently released pages, taken alongside new research on triclosan, raise questions about whether the agency did appropriate [...]

Alcohol based mouthwash and oral cancer – too much confusion

Source: scienceblogs.com Author: Francis Mawanda If you are like me, you probably always and almost faithfully, include a bottle of mouthwash on your grocery list especially after watching and/or listening to the numerous commercials in the media which claim that you will not only get long lasting fresh breath, but also freedom from the germs that cause plaque and gingivitis. However, many proprietary mouthwashes including my favorite brand contain Alcohol (ethanol) which also gives them the characteristic burn we have to endure, albeit for a few seconds each day, but safe in the knowledge that the product is hard at work killing all the germs that give us bad breath and may cause plaque and gingivitis. But the question I continually ask myself is whether regular or long term use of these products is safe especially after reading the numerous research reports and newspaper articles suggesting a possible link between long term use of alcohol based mouthwashes and oral cancer. Several research studies have reported finding an association between long term mouthwash use and oral cancer (1, 2, 3). For example, in a study conducted by Wynder and colleagues (1), they found a significant association between mouthwash use and oral cancer. A bigger multi-site study by Guha and colleagues (3) comparing participants who reported having used mouthwash to those who reported never having used mouthwash found that individuals who reported using mouthwash more than twice a day were nearly six times more likely to develop oral squamous cell carcinoma compared [...]

Saliva tests may help with disease diagnosis

Source: www.readingeagle.com Author: John Reitz, DDS The Dentist's Chair Jim: With the newly discovered connection between oral health and overall health, is there anything a dentist can tell about my overall health from looking in my mouth? Dr. Reitz: Dear Jim, a dentist can tell if you have gum disease and tooth decay by looking in your mouth, but to determine your overall health he may need a sample of your saliva. Instead of having just a blood test by your physician, your dentist will soon have the ability to diagnosis systemic disease by doing a saliva test. In dental school I was taught that saliva's function was to neutralize acids and help swallow food. We are now finding that saliva is more complex than originally thought, containing over 1,000 different proteins. The question now is why are the proteins there. Recent advances in technology have found saliva contains indicators, either genes or salivary proteins called biomarkers, of systemic disease. Of the 1,000 salivary proteins already identified, only specific proteins are found in patients with systemic disease. Research at the University of California, Los Angeles is expected to get Food and Drug Administration approval within two years for a saliva test that can detect pancreatic cancer. Other studies have found biomarkers for breast cancer, oral cancer, diabetes, arthritis, heart disease and autoimmune disorders. In addition to finding systemic diseases, saliva tests will determine a person's chances of getting tooth decay. Some promising studies have identified biomarkers for a predisposition to [...]
