Tongue Piercings: An Expensive Habit

Tongue Piercing: An Expensive Hobby

Do you have your tongue pierced? Sure, it only cost you $40, and that includes the jewelry. But in the end, it might just be the most expensive hobby you have. It turns out that the gums of people with piercings are exposed to high amounts of all sorts of bacteria, and that causes the gums in the front teeth to recede, leading to something called periodontal disease. As if that’s not enough of a problem, half of people with piercings wind up with chipped teeth, mostly in the back of the mouth. Dentistry to salvage your teeth can dwarf the cost of the initial piercing, even if you have a diamond stud.

Whether you care about the appearance of your teeth or not, piercings will eventually make your gums bleed and become sore – that’s called gingivitis. And when the roots of the teeth are exposed, they become sensitive to cold and heat and eventually lead to tooth loss.

But that’s not the only problem associated with tongue piercings. It turns out that bacteria love the channel that traverses your tongue. And these germs set up little communities called biofilms on the surface of the studs. The bugs create little fortresses that make the bacteria resistant to mouthwash and even antibiotics. Studs made of stainless steel make the best homes for these colonies of bacteria and ones made of the plastic called polypropylene make the worst. Bacteria in your mouth cause increased inflammation in your body. Many doctors think that this type of inflammation can lead to all sorts of problems, including heart disease.

So, the simple act of piercing your tongue, seemingly so cool to 17-year-olds, can lead to all sorts of dental and medical problems.

Think about this: the next time you pucker up and kiss your pierced mate, as you entwine your tongues, you will be visiting the 80 or more different species of bacteria that call that piercing “home."

US Regulators Call For Less Fluoride in Drinking Water

U.S. regulators call for less fluoride in drinking water

 

January 7, 2011 -- Americans are getting fluoride from a variety of sources that did not exist in the 1940s, when community water fluoridation first got under way. Water consumption patterns have changed too.

So, while continuing to stress the benefits of fluoride, officials from the U.S. Department of Health and Human Services (HHS) have proposed that the recommended level of fluoride in drinking water be set at the lowest end of the current optimal range to prevent tooth decay. At the same time, officials from the U.S. Environmental Protection Agency (EPA) announced they are initiating a review of the maximum amount of fluoride allowable in drinking water.
In a joint statement released January 7, officials from both agencies framed the actions as a way of maximizing the health benefits of water fluoridation to Americans by continuing to prevent tooth decay while reducing the possibility of ill effects.
"One of water fluoridation's biggest advantages is that it benefits all residents of a community -- at home, work, school, or play," said HHS Assistant Secretary for Health Howard Koh, MD, MPH, in the statement. "And fluoridation's effectiveness in preventing tooth decay is not limited to children but extends throughout life, resulting in improved oral health."
EPA Assistant Administrator for the Office of Water Peter Silva stressed that the agencies are reviewing fluoride levels in response to "the most up-to-date scientific data."
"EPA's new analysis will help us make sure that people benefit from tooth decay prevention, while at the same time avoiding the unwanted health effects from too much fluoride," he said.
Fluoride occurs naturally in drinking water, but levels vary from low to high in different regions of the U.S.
Lifestyle changes
At what are considered optimum levels, public health officials and the ADA have long promoted fluoride as a way of reducing dental caries. But research has also found that consumption at excess levels may cause fluorosis and skeletal deformities (Journal of the American Dental Association, November 2008, Vol. 139:11, pp. 1457-1468; October 2009, Vol. 140:10, pp. 1228-1236; January 2011, Vol. 142:1, pp. 79-87).
For the past 65 years, communities across the country have been supplementing naturally occurring fluoride in their water supplies to reach a level considered sufficient to promote oral health, especially among children. The fluoride level long recommended by health officials to prevent caries has been set at a range of 0.7 to 1.2 milligrams per liter (mg/L) of water. The HHS is now proposing the level be set at 0.7 mg/L of water.
The reassessment was initiated in part due to new research into changes in diet and lifestyle, as well as regional water consumption patterns seen over time, officials said. The old range was in part based upon differences in regional climate and water consumption that have become somewhat outdated with the advent of air conditioning. In addition, Americans have access to more sources of fluoride than in the past. Besides water, other sources of fluoride include dental products such as toothpaste and mouth rinses, prescription fluoride supplements, and fluoride applied by dental professionals.
The findings are also being used to guide the EPA in making a determination of whether to lower the maximum amount of fluoride allowed in drinking water. Under the Clean Water Act passed by Congress in 1974, the EPA must determine the level of contaminants in drinking water at which no adverse health effects are likely to occur. The EPA has set the maximum contaminant level goal for fluoride at 4.0 mg/L, based on the best available science to prevent potential health problems.
But in 2006, an analysis by the National Research Council concluded the EPA's drinking water standard was too high to protect against adverse health effects.
And the National Academy of Sciences reviewed new data on fluoride and issued a report recommending that EPA update its health and exposure assessments to take into account bone and dental effects and to consider all sources of fluoride.
Any formal change to the drinking water regulation would be made only after a formal proposal, public comment period, and finalization process.
As of 2008, 195.5 million Americans, or 72.4 % of the population on public water systems, had access to optimally fluoridated water, according to the most recent statistics available from the Centers for Disease Control and Prevention, which has hailed the fluoridation of drinking water as one of the 10 great public health achievements of the 20th century.
Opposition and support
In some communities, however, efforts have met continued resistance from opponents who contend that fluoridation amounts to forced medication or an unwanted intrusion of government into private life.
Fluoridation opponent Paul Connett, PhD, who heads the Fluoride Action Network, dismissed the January 7 announcement as "spin and collusion" between federal health officials and the dental establishment to continue fluoridation, which he argues is dangerous, especially to children.
"It's a stupid bloody practice," Connett said. "Once you put a medicine in the water, you can't control the dose."
The ADA commended the move by health officials to revisit fluoride guidelines and standards.
"As a science-based organization, the ADA supports the Department of Health and Human Services' recommendation," the ADA said in a statement. "This adjustment will provide an effective level of fluoride to reduce the incidence of tooth decay while minimizing the rate of fluorosis in the general population."
ADA President Raymond Gist, DDS, called the HHS recommendation "a superb example of a government agency fulfilling its mission to protect and enhance the health of the American people."
Shelly Gehshan, director of the Pew Children's Dental Campaign, praised the actions of the HHS and EPA.
"These announcements show that federal health officials are carrying out their proper role and relying on the best science to do so," she told DrBicuspid.com. "The public can feel reassured that optimally fluoridated water is a safe, effective way for people of all ages to prevent tooth decay."
The notice of the proposed recommendation will be published in the Federal Register soon, and HHS will accept comments from the public and stakeholders on the proposed recommendation for 30 days at CWFcomments@cdc.gov. HHS is expecting to publish final guidance for community water fluoridation by spring 2011.

Medicine and Oral Health Screenings

Many physicians still resist doing oral health assessments


December 30, 2010 -- It's been 10 years since the U.S. surgeon general's report on oral health in America, which among other things advocated interdisciplinary training between medical and dental providers. But current research shows that primary medical care providers are still not comfortable performing basic oral health assessments, and many consider oral health outside their realm of practice.

"The time has arrived for each profession to recognize the benefit of coordinated treatment plans to better manage patients," Charles Cobb, DDS, PhD, professor emeritus at the University of Missouri-Kansas City School of Dentistry and co-author of a new study that used the theory of planned behavior to examine nurse practitioners' understanding of the link between periodontal disease and systemic health (Journal of Periodontology, December 2010, Vol. 81:12, pp. 1805-1813).
The researchers surveyed 200 primary care providers about practice behaviors, attitudes, opinions, and knowledge regarding the periodontal disease-systemic link and used 137 partially and fully complete questionnaires for their data analyses. Of the 137 questionnaires, 123 were completed by nurse practitioners.
Dr. Cobb and colleagues found that 22% of the respondents reported they always or routinely screen for periodontal disease. Using the theory of planned behavior -- which explains behavior as a function of intent, including such factors as attitudes, social norms, and perceived control -- they found that the likelihood of screening increased if the providers felt confident in their training (attitude), felt like it was within their scope of practice (social norm), and felt that they had control over office protocols (control).
"A change in professional and peer expectations about periodontal assessments would be an important factor in improving rates of screening," said Dr. Cobb. Limited time and concerns over reimbursement were also found to be factors.
Interdisciplinary/interprofessional education
In addition to recognizing the importance of the oral and systemic health link, primary medical care providers are being asked to assess oral health to help overcome disparities in access to care. Low-income and minority children, the elderly, people with developmental disabilities, and adults with less than a high school education are at particular risk for limited access to oral health services and a shortage of dental providers, according to the U.S. Centers for Disease Control and Prevention.
To address these disparities, health personnel who encounter patients without oral healthcare need to be able to perform simple assessments (Journal of Dental Education, May 2004, Vol. 68:5, pp. 505-512). Personnel also need to be aware of oral health resources in the community that will take patients on referral. In the case of infants and young children in the U.S., 95% have a physician but very few have a dentist, the researchers noted.
Other studies have shown that pediatric residents receive little training before completing their programs. When 661 pediatric graduating residents were surveyed in 2006, 35% of respondents stated they received no oral health training during residency (Pediatrics, August 2008, Vol. 122:2, pp. e465-e471). Of those who did receive some training, 73% had less than three hours of training and only 14% had clinical observation time with a dentist.
Similarly, a survey sent to 1,618 postresidency fellows of the American Academy of Pediatrics found that while more than 90% of pediatricians said they should examine their patients' teeth for caries and educate families about preventive oral health, in practice only 54% reported examining the teeth of more than half of their 0- to 3-year-old patients (Academic Pediatrics, November-December 2009, Vol. 9:6, pp. 457-461). In addition, the survey found that less than 25% of pediatricians had received oral health training.
Primary care training for adults fared no better. In a survey issued to incoming internal medicine trainees, 82% of the 115 respondents reported they never asked patients if they had been diagnosed with periodontal disease, and 90% reported not receiving any training about periodontal disease in medical school (J Periodontol, March 2010, Vol. 81:3, pp. 359-363). Nearly 70% reported that they were not comfortable "at all" doing a simple periodontal exam, 46% felt that discussing/screening for periodontal disease was outside their role as physicians, and 23% said they never referred patients to dentists.
"Somehow, there must be a recognition of value to doing even a 'tongue blade' visual examination of the oral cavity to determine obvious signs of inflammation," says Dr. Cobb. "Currently, such a visual examination is not part of the routine in medicine and nursing."
However, the "historic separation" of medicine and dentistry have kept the systems of education and training, financing, and service delivery separate, noted Wendy Mouradian, MD, MS, professor of pediatric dentistry and pediatrics at the University of Washington Schools of Dentistry and Medicine and co-author on the 2009 Academic Pediatrics and 2004 Journal of Dental Education papers.
"While microorganisms know no such barriers, health professional education and primary care practice lags behind today's science," she told DrBicuspid.com. "What is needed are cultural changes within medicine and dentistry and practical strategies to ensure better communication between practitioners and integration, or at least coordination, of health services."
Improving education
Efforts are under way to address these disparities. A 2003 Institute of Medicine (IOM) report, "Health Professions Education: A Bridge to Quality," concluded that all health professionals should be educated to:
  • Provide patient-centered care
  • Work in interdisciplinary teams
  • Employ evidence-based practice
  • Apply quality improvement approaches
  • Utilize informatics
Using the IOM report as a guide, and as part of a study initiative called "New Models of Dental Education" funded by the Josiah Macy Jr. Foundation, three panels were convened to discuss the future of dental education. Panel 2 of the Macy Study, held in December 2006 and co-sponsored by the American Dental Education Association (ADEA) and the Association of American Medical Colleges (AAMC), discussed education and clinical training of both dentists and physicians (J Dent Educ, February 2008, Vol. 72:2 Suppl., pp. 73-85).
The panel concluded that medical providers would best be trained in oral health using a "spiral curriculum" on oral-systemic health in five key areas: caries, periodontal disease, dental public health issues, oral cancer, and the oral-systemic health relationship. Optimally, content from each of these five areas would be interspersed throughout medical training, starting in basic science courses and then reinforced at higher educational levels and in clinical rotations.
The 19th-century distinction between medicine and dentistry is becoming obsolete as the relation between oral and systemic health blurs, the Macy Panel 2 noted. To integrate new knowledge across the research literature, the panel recommended that clinicians become "sophisticated users of science and technology and avid consumers of interdisciplinary research to best implement the latest in evidence-based practice."
Building on this work, the AAMC will be mounting an effort to expand and disseminate curriculum resources available to medical schools through a cooperative agreement awarded by the Maternal and Child Health Bureau of the Health Resources and Services Administration (HRSA), Dr. Mouradian noted. This award reflects a new focus on oral health within the federal government. Both HRSA and the U.S. Department of Health and Human Services have identified the integration of oral health into primary care as strategic priorities.
"All this will take time and work," Dr. Mouradian said. "But without such efforts, we will be seriously hampered in our ability to address the profound oral health disparities identified by the surgeon general."
