Abstract –

Objectives: To review the effect of lavender scent on anticipatory anxiety in dental participants.

Methods: In a cluster randomized-controlled trial, patients' (N = 340) anxiety was assessed while waiting for a scheduled dental appointment, either under the odor of lavender or with no odor. Current anxiety, assessed by the brief State Trait Anxiety Indicator (STAI-6), and generalized dental anxiety, assessed by the Modified Dental Anxiety Scale (MDAS) were examined.

Results: Analyses of variance (anovas) showed that although both groups showed similar, moderate levels of generalized dental anxiety (MDAS F(1,338) = 2.17, P > 0.05) the lavender group reported significantly lower current anxiety (STAI: F(1,338) = 74.69, P < 0.001) than the control group.

Conclusions: Although anxiety about future dental visits seems to be unaffected, lavender scent reduces state anxiety in dental patients.

American Dental Association petitions FDA to classify, regulate tooth-whitening products

CHICAGO, November 20, 2009— The American Dental Association (ADA) today asked the U.S. Food and Drug Administration (FDA) to establish appropriate classifications for tooth-whitening chemicals.

Citing concern about the safety of whitening products that are often administered without the benefit of professional consultation or examination by a dentist, the Association said that the application of chemically based tooth whitening or bleaching agents can harm teeth, gums and other tissues in the mouth.

The ADA pointed out that such concerns have prompted many states to prevent application of tooth whitening products in non-dental settings.

"The tremendous expansion of products available directly to consumers and application of products in venues such as shopping malls, cruise ships, and salons is troubling since consumers have little or no assurance regarding the safety of product ingredients, dosesor the professional qualifications of individuals employed in these non-dental settings," said ADA President Dr. Ron Tankersley and Executive Director Dr. Kathleen O'Loughlin, in a letter to the agency.

"Application of whitening/bleaching materials is not risk-free and may not be appropriate for all dark or discolored teeth," they wrote.

Dentists Can Help to Identify Patients at Risk of a Heart Attack

ScienceDaily (Nov. 25, 2009) — Dentists can help to identify patients who are in danger of dying of a heart attack or stroke, reveals a new study from the Sahlgrenska Academy. Thanks to the study, six men who thought they were completely healthy were able to start preventive treatment in time.

Dentists are really proud of their profession and feel no need to encroach upon doctors' territory," says senior dental officer and professor Mats Jontell at the Sahlgrenska Academy. "However, we wanted to find out if we as a profession could identify patients at risk of cardiovascular disease."

The study involved 200 men and women over the age of 45 who did not have any known cardiovascular problems. During a routine visit to their normal dentists in Borås and Gothenburg they were also checked out for known risk factors for cardiovascular disease.

"These risk factors are not normally manifested in the mouth, which is why the dentists went beyond their normal check-up routine," says Jontell. "They also took the patients' blood pressure and checked total cholesterol and blood sugar levels."

The risk of a fatal cardiovascular disease was calculated using a software known as HeartScore. The dentists felt that twelve men had a ten per cent risk of developing a fatal cardiovascular disease over the next ten years and advised them to see their doctors. Six of the twelve were subsequently prescribed medication to lower their blood pressure.

"Dentists regularly see a very large percentage of the Swedish population, and if there is sufficient interest they could also screen for cardiovascular risk factors which, untreated, could lead to a heart attack or stroke," says Jontell.

IMTEC Launches “My MDI story” Website

Ardmore, Okla. – November 23, 2009 – IMTEC announces the launch of, a new website featuring dentists and patients sharing stories of the positive impact MDI implants have made in their practices and lives. On the site, dental professionals will find other dentists who are experienced in placing the mini implants, and who explain the benefits of offering the service. Additionally, patient testimonial videos illustrate the dramatic differences that MDI implants have made for patients. The site offers dentists and patients a resource for information to better understand the mini implant system and procedure.
As dentists on the site explain, MDI implants enable denture stabilization via a minimally invasive one-hour procedure. They are well-tolerated by patients, and can be used on patients who are not candidates for traditional implants. Additionally, the system’s reasonable cost makes it affordable for both dentists and patients.
“The new website makes it simple for patients to hear the benefits of the procedure, and also to locate a dentist who offers the service,” said Tay Harvey, Global Implant Category Manager, IMTEC. “Additionally, dental professionals will be able to hear from other dentists on the productivity gains that the MDI system can bring.”
One dentist featured on the site, Dr. Ian Erwood of Unionville, Ontario, states that he had “instant success” with the procedure in his practice. “With the MDI protocol,” he states, “we’ve been able to increase the revenue in our practice due to the atraumatic technique, the reduction in material costs, and the number of referrals we’ve gained.”
The site offers dentists links to additional information on DVD, as well as the IMTEC MDI website and a schedule of MDI Certification Seminars.

U.S. military halts rollout of electronic dental record

U.S. military halts rollout of electronic dental record
November 23, 2009
By: Kathy Kincade, Editor in Chief

The highly anticipated rollout of the U.S. Military Health System's (MHS) first integrated electronic medical and dental record has hit a snag.

Deployment of AHLTA Dental, the dental component of the military's electronic health record known as AHLTA (Armed Forces Health Longitudinal Technology Application), is undergoing a "strategic pause" to enable the MHS to "further analyze some existing functions within other systems," according to Charles Campbell, MHS Chief Information Officer.

"MHS is initiating a pause to do a pulse check of where we are with the process and make modifications based on the needs of our healthcare providers," Campbell said. "We need to make sure we can keep pace with the dental community's evolving needs, so I would rather take time to examine those needs and make adjustments now rather than replacing the system later."

The AHLTA electronic health record is designed to integrate all dental and medical information in the MHS Clinical Data Repository, which maintains records on more than nine million active-duty and retired military personnel and their families.

MHS launched the dental module of AHLTA in March of this year. MHS had originally planned to deploy AHLTA Dental to nearly 400 Army, Air Force, and Navy dental clinics worldwide by the end of 2010, with the Army scheduled to begin rolling it out to 18 clinics this month. But on November 3, news reports indicated that the Army was pulling out of the deployment, opting to use its own dental record application instead.

In reality, all branches of the military are delaying the AHLTA Dental rollout, according to Michael Kilpatrick, M.D., MHS Director of Strategic Communications.

"This schedule delay is the result of an MHS agreement with all three Services to review existing options prior to making a decision to complete the remaining deployment," Dr. Kilpatrick told in an e-mail.

Reviewing their options

In addition, while the Army's Corporate Dental Application (CDA) provides some capabilities that are not in the AHLTA Dental module, it was not developed to be an electronic dental record, Dr. Kilpatrick said.

"The CDA is a modular, Web-based application that meets several of the required dental capabilities other than the sustaining base electronic dental record capability," he said. "As it progressed, however, it acquired many robust features that allowed users to manage day-to-day dental activities."

In June 2008 the Army awarded Harris Corporation an $11.6 million contract to maintain and enhance the CDA.

"As we work to improve our electronic health record, we need to put the tools in the hands of our providers that can best support their needs for rapid documentation and access to their patient's health information," said Jack Smith, M.D., acting Deputy Assistant Secretary of Defense (Health Affairs) Clinical and Program Policy. "While we're still evaluating the business case for a change, the CDA appears to provide a reasonable alternate to address many of the current needs of our dental providers."

Because the CDA is currently available at Army and Air Force dental clinics, including remote locations in Theater, "it makes sense to review our options," Campbell added.

Despite the delay, Kilpatrick emphasized the MHS's objective to deploy a comprehensive electronic dental and medical record.

"The most important aspect of an electronic medical record is to be able to render accurate, secure patient information to the medical provider at the point of care," he said. "That goal has not changed."

Kerr Expands Tissue Management Line with Hemostasyl

ORANGE, CA – October 15, 2009 – Kerr introduces the latest innovation in tissue management, HemostasylTM—a highly efficient hemostatic agent that stops bleeding with precision and ease. When moderate bleeding occurs and gingival retraction is not required, Hemostasyl is an ideal choice. This product is exceptionally easy to place, and less material is required compared to other similar hemostatic agents on the market.
Product Manager James Lobsenz said, “With Hemostasyl, doctors now have a material that is incredibly easy to dispense using a convenient syringe delivery and a viscosity that stays in place and controls blood and other fluids well.”
Hemostasyl is brightly colored, so it is easy to see and clean up, and its composition helps adhere to soft and hard tissue with ease, making placement a breeze. With a concentration of 15% aluminum chloride, this material is an effective way to stop bleeding in many clinical applications such as Class V composite placement, cementation, and scaling in perio cases. Compromising esthetics of the procedure is not a worry—Hemostasyl contains no ferric sulfate, unlike similar products on the market, which can stain proteins a black color, including soft tissue and dentin.
For gingival retraction needs, the Kerr Tissue Management line also offers ExpasylTM, an atraumatic gingival retraction paste, now in a pleasant new strawberry taste.
To learn more about Hemostasyl or our broad portfolio of products, visit or call 800.KERR.123. To find out more about continuing education online and free CE credit, visit Kerr University at for upcoming live webcasts, on-demand video, and the latest CE articles.

Molecular DNA Tests Positioning Dental Professionals at the Forefront of Oral Medicine - Company Planning the Launch of HPV/Oral Cancer DNA Test in 2010

Nashville, TN – November 16, 2009 – OralDNA Labs™ Inc. (,
a specialty diagnostics subsidiary of Quest Diagnostics® Incorporated (NYSE: DGX) focused on bringing advanced laboratory testing to the dental community, today announced the availability of two revolutionary molecular tests to help periodontists and general dentists identify patients with and at risk for periodontal disease. MyPerioPathsm detects the presence and quantity of specific bacteria associated with periodontal disease, while MyPerioIDsm PST®, which the company licenses from Interleukin Genetics, provides a means of quickly and accurately1 assessing an individual’s genetic risk for periodontal disease.

Used together, the new salivary DNA diagnostic tests can help dental professionals reduce patient incidence of periodontal disease. MyPerioPathsm provides early and accurate1 diagnosis of existing periodontal disease by identifying and measuring specific types of bacteria, while MyPerioIDsm PST® assesses a patient’s genetic predisposition to developing periodontal disease well before physical symptoms occur. The company has launched a national dental industry awareness and training program to support the profession’s understanding and effective use of the new tools.

According to OralDNA Inc. senior vice president and general manager Robert Walker,

the company has been introducing the tests to leading dental industry practitioners
during the past year. “Leading periodontists and general dentists are already relying
on the MyPerioPathsm and MyPerioIDsm PST® salivary diagnostic tests to provide valuable insights for enhanced patient care, and as important tools in the fight against periodontal disease. We believe these tests will not only help put dental professionals at the forefront of oral medicine, but also enable them to provide more comprehensive and accurate treatment plans for their patients.”

According to the American Dental Association, an estimated 75% of all Americans over the age of 35 have some form of periodontal disease2 and research conducted during the past 10 years has provided insight into the Perio / Systemic Connection and the link between chronic periodontal infections and heart disease, diabetes, stroke, and some forms of cancer.3,4

Within the next year, OralDNA expects to add the clinician-administered oral DNA HPV test, OraRisksm HPV, for use in assessing the risks associated with certain types of oral cancer, and intends to continue to broaden its menu of salivary diagnostic tests for use in oral medicine.

For more information, education, and training related to OralDNA’s salivary DNA diagnostic tests, dental professionals, including periodontists, general dentists, and dental hygienists, should visit or call (877) 577-9055.

British Dental Association Attacks Unacceptable And Growing Chasm" In Oral Health Inequalities

An "unacceptable and growing chasm" exists in the UK between those with good and poor oral health, according to the British Dental Association's (BDA's) Oral Health Inequalities Policy which is published today. The policy highlights the close association between low socio-economic status and poor oral health, calling for more focus on preventive care. It also says there should be a more integrated approach to oral health from health and social care providers. Furthermore, the paper argues greater priority should be given to particular patient groups, including those with disabilities, older people and the prison population.

The contributions of alcohol and tobacco to oral health inequalities are stressed by the paper, particularly as risk factors for oral cancer. It calls for resources to enable dental professionals to take a more preventive approach, including counselling patients on the dangers associated with alcohol and tobacco products, referring patients to smoking cessation schemes and the extension of the ability to prescribe Nicotine Replacement Therapy (NRT) to a wider group of health professionals.

Professor Damien Walmsley, Scientific Adviser to the BDA, said:

"There has been a significant improvement in the nation's overall oral health over the last 30 years, but despite that we still see a huge disparity that is all-too-often related to social deprivation. It is completely unacceptable that in Britain, in 2009, such a wide gap should exist.

"Much good work to address this problem has begun, and this report commends a number of schemes such as Brushing for Life and Sure Start that are starting to make a difference. However, a great deal of work remains to be done and it is vital dentists are supported in doing it."

The Oral Health Inequalities Policy is available at:

Form Of Mercury In Older Dental Fillings Unlikely To Be Toxic

Amid the on-going controversy over the safety of mercury-containing dental fillings, a University of Saskatchewan research team has shed new light on how the chemical forms of mercury at the surface of fillings change over time.

Their work, just published in the American Chemical Society journal Chemical Research in Toxicology, shows that the surface forms of mercury in older "silver" fillings (also known as amalgams) may be less toxic than previously thought.

"The dental amalgam on the surface of an old tooth filling may have lost as much as 95 per cent of its mercury but what's left is in a form that is unlikely to be toxic in the body," said U of S Canada Research Chair Graham George who led the study.

But the team cautions that due to the significant mercury loss over time, human exposure to mercury lost from fillings is "still of concern" and that further research is needed to determine when, how and in what form mercury is lost from fillings.

Mercury-based fillings have been used by dentists to repair teeth for well over a century. But in recent decades, their use has become controversial due to concerns about exposure to potentially toxic mercury.

"Mercury can potentially exist in several different chemical forms, each with a different toxicity," said George. "Prior to our work, little was known about how the chemical forms of mercury in dental amalgam might change over time."

The team used a special X-ray technique at the Stanford Sychrotron Radiation Lightsource to probe the amount and chemical nature of mercury at the surface of both freshly prepared metal fillings and aged fillings (about 20 years old) obtained from the U of S dental clinic's tooth bank.

While the fresh fillings contained metallic mercury, which can be toxic, aged fillings contained a form of mercury called beta-mercuric sulfide or metacinnabar which is unlikely to be toxic in the body. For this reason, grinding or polishing during dental cleaning is unlikely to cause any toxic effects.

But of potential greater concern is the nature of the surface mercury lost from fillings. This may be due to evaporation (with subsequent inhalation and leaching of mercury into saliva), exposure to some kinds of dental hygiene products such as those containing peroxides, exposure to certain sulphur-containing foods (such as onion and garlic or coffee), or other factors.

"Possibly this missing mercury is in the less toxic form of mercury (metacinnabar) abraded from the surface of the filling. Or alternatively, it may be mercury lost prior to formation of the metacinnabar through various types of exposures," said George.

In North America, the traditional view is that the advantages of mercury-containing amalgam outweigh any possible health risks, and for this reason, mercury-containing dental amalgams are still widely used. However, several countries including Sweden and Norway have banned the use of mercury in fillings.

Other members of the team include Satya Singh, Jay Hoover, and Canada Research Chair Ingrid Pickering. This project was supported by a grant from the Canadian Institutes of Health Research.

Cambridge MedCom to Shoot Free 30-Second Video for Dentists' Websites at The Greater NY Dental Meeting

Cambridge MedCom to Shoot Free 30-Second Video for Dentists' Websites at
The Greater NY Dental Meeting * Come to Health Compliance Team Booth # 826

New York, New York – Cambridge MedCom, the nation's leading boutique internet, marketing, and public relations firm serving dentists, and the larger healthcare community, will be shooting free videos for dentists at the Greater NY Dental Meeting at Jacob Javitz from November 29, 2009 to December 2, 2009. “The internet represents a tremendous opportunity for dentists to expand their business and acquire new patients, but only if it's done right,” said Abe Kasbo Chairman of Verasoni Worldwide, the parent company of Cambridge MedCom.

Cambridge MedCom will provide participating dentists with a complimentary 30-second “webisode” to use on their website, Youtube channel, facebook, Linkedin, twitter and blogs. The videos will be professionally taped, edited on the spot, uploaded to the dentist's email account, and placed on Cambridge's Branded Youtube Channel for additional exposure. “Having a website without an integrated marketing plan is akin to flying a plane without a pilot, so it's critical that dentists implement a content distribution strategy to ensure their site stays ahead of the competition,” continued Mr. Kasbo. “Additionally, various active organic and non-organic strategies must be incorporated in order to effectively optimize a websites' position, and that takes fresh thinking along with work.”

Dentists will be asked to dress for the on-camera interview. The interview will be brief, focused on one area of interest to each dentist, and specifically designed for online viewing. The video's positioning on Youtube, which happens to be the second largest search engine in the world, ought to contribute positively to the participating dentist's website search engine relevance.

How To Get Your Free Interview:

Interview spots are limited to 32 per day and, dentists must reserve their spot. This offer is on first-come, first-serve basis. Dentists will be able to reserve an interview by sending an email to and MUST include the following:

• Dentist full name
• Practice Name
• Practice address
• Practice phone number
• Practice fax number
• Practice email address
• Name of practice manager

Dentists must provide the date of attendance and choose from the following time categories:

• Early
• Mid-morning
• Noon - early afternoon
• Late afternoon

Once the time category is chosen, Cambridge MedCom will provide an exact time based on the category chosen by the dentist. Dentists will forfeit their interview spot if unable to make the time reserved.

Occupational exposure to bisphenol-A (BPA) and the risk of Self-Reported Male Sexual Dysfunction.

Why is this dental? BPA is in composite. MJ

Hum Reprod. 2009 Nov 10. [Epub ahead of print]
Occupational exposure to bisphenol-A (BPA) and the risk of Self-Reported Male Sexual Dysfunction.

Li D, Zhou Z, Qing D, He Y, Wu T, Miao M, Wang J, Weng X, Ferber JR, Herrinton LJ, Zhu Q, Gao E, Checkoway H, Yuan W.

Division of Research, Kaiser Foundation Research Institute,Kaiser Permanente Northern California, 2000 Broadway, Oakland, CA 94612, USA.

BACKGROUND Animal studies have suggested that bisphenol-A (BPA) is a potential human endocrine disrupter; but evidence from human studies is needed. METHODS We conducted an occupational cohort study to examine the effect of occupational exposure to BPA on the risk of male sexual dysfunction. Current workers from BPA-exposed and control factories were recruited. The exposed workers were exposed to very high BPA levels in their workplace. Male sexual function was ascertained through in-person interviews using a standard male sexual function inventory. RESULTS BPA-exposed workers had consistently higher risk of male sexual dysfunction across all domains of male sexual function than the unexposed workers. After controlling for matching variables and potential confounders, exposed workers had a significantly increased risk of reduced sexual desire [odds ratios (OR) = 3.9, 95% confidence interval: 1.8-8.6), erectile difficulty (OR = 4.5, 95% CI 2.1-9.8), ejaculation difficulty (OR = 7.1, 95% CI 2.9-17.6), and reduced satisfaction with sex life (OR = 3.9, 95% CI 2.3-6.6). A dose-response relationship was observed with an increasing level of cumulative BPA exposure associated with a higher risk of sexual dysfunction. Furthermore, compared with the unexposed workers, BPA-exposed workers reported significantly higher frequencies of reduced sexual function within 1 year of employment in the BPA-exposed factories. CONCLUSIONS Our findings provide the first evidence that exposure to BPA in the workplace could have an adverse effect on male sexual dysfunction.

Noncovered services: House supports legislative action to counter trend

Seeking legislative action to prevent dental plans from capping the amount dentists can charge for services a plan doesn't cover, the 2009 House of Delegates adopted Resolution 59H-2009.

Dental plans began implementing contract provisions holding dentists to maximum allowed fees for services for which no benefit is available with increasing frequency last year.

Many dentists fear such provisions limit access.

Aribex Files Patent Infringement Complaint Against Bio-Ray Prox

Just an FYI I use Nomads in my office and like them a lot. MJ

OREM, UTAH, USA—30 Oct 2009—Aribex, Inc., of Orem, Utah, today announced that it has filed a patent infringement complaint for unspecified damages against manufacturer DigiMed Co., Ltd (of Seoul, Korea), Sigma Biomedics (of Buffalo Grove, Illinois), and Dentalaire Products (of Fountain Valley, CA). Sigma and Dentalaire distribute the Bio-Ray Prox, a portable x-ray device which is manufactured in Korea by DigiMed. The complaint, filed in the U.S. District Court in Salt Lake City, comes after a number of attempts by Aribex to resolve concerns over the alleged infringement of Aribex patents by several different manufacturers and importers.

Aribex is the developer of a novel class of handheld x-ray sources, with patented technology enabling a lightweight and easily transported design. Their popular NOMAD® family of x-ray devices is currently used in the dental, veterinary, and forensic disciplines.

The complaint alleges that Aribex intellectual property rights are being knowingly and unfairly violated. According to Dr. D. Clark Turner, president and CEO of Aribex and inventor of the NOMAD handheld x-ray, "Aribex has spent considerable time and money to establish the value proposition of handheld x-ray. We consider our intellectual property to be one of our core assets and plan to aggressively defend and enforce our IP rights. This is the first visible step in that process."

Lanmark Group to Review Highlights of Benchmark RDH Survey During Greater New York Dental Meeting

Results of Recent In-Depth Poll Will Provide Invaluable Market Intelligence
to any Company Striving to Effectively Engage with Today’s Registered Dental Hygienist

Eatontown, NJ (November 3, 2009) – Lanmark Group, the dental industry’s leading full-service, business-to-business advertising, marketing, and public relations agency, will be scheduling appointments to review the highlights of its recent benchmark survey of dental hygienists, during the Greater New York Dental Meeting.

The online survey was conducted independently by Lanmark’s Research Team and polled close to 300 dental hygienists on a wide range of topics including product preferences, career satisfaction, association affiliation, social media usage, publication readership, professional relationships, hygienist-friendly companies, oral/systemic link relevance, product recommendations, and much more.

“This is was a detailed survey that required participants to spend about a half hour to complete,” commented Lanmark Chief Strategy Officer, Michael McCarthy. “Our first take away from this process was that hygienists are a dedicated, passionate group of dental professionals who take the time to communicate with any company willing to listen – We’re listening!”

The full results of this survey will provide valuable market intelligence to any company that markets products, materials and services to the dental hygienist. “There are some surprising answers that will shatter some preconceived notions, plus enlightening answers to questions that have simply never been asked before,” explained McCarthy. “No hygiene-focused marketing director or product manager should be without the in-depth findings of this survey.”

Senior members of the Lanmark Research Team will be on hand during the Greater New York Dental Meeting to present the highlights of this benchmark survey of dental hygienists, or to explain how they can develop a custom research project if needed. To schedule a free 30-minute consultation, call Erin Foster at 732-389-4500 ext. 128 or send an e-mail to

Lanmark Group’s recent benchmark survey of dental hygienists was conducted independently by the company’s research department, using its proprietary database. The survey was not developed in cooperation with any publications, associations, or third party groups.

Thanks to Continental Airlines

I had been away in Mexico on vacation. I was scheduled to leave at the same time Hurricane Ida was supposed to be very close to Cancun. I called Continental Airlines late in the afternoon to see if they had a late flight out of Cancun before the hurricane was to pass the area. Low and behold they were sending a plane just for that purpose! So Continental added an unscheduled flight to take out all those people requesting to leave Cancun before the hurricane.

I boarded my flight at about 10 o'clock PM and was in Houston at midnight. An added flight and now fees to change. Most importantly my family was out of harms way.

So a very big "THANK YOU" to Continental Airlines for excellent customer service!!!!

Opinions of American and Swedish Orthodontists about the Role of Erupting Third Molars as a Cause of Dental Crowding.

Angle Orthod. 2009 Nov;79(6):1139-42.
Opinions of American and Swedish Orthodontists about the Role of Erupting Third Molars as a Cause of Dental Crowding.

Tüfekçi E, Svensk D, Kallunki J, Huggare J, Lindauer SJ, Laskin DM.

Abstract Objective: To compare the opinions of Swedish orthodontists and American orthodontists regarding the association between third molar eruption and dental crowding. Materials and Methods: A survey was distributed to Swedish orthodontists (n = 230) asking their views on the force exerted by erupting third molars, its relationship to crowding, and their recommendations for prophylactic removal. Results were compared with those from a similar study conducted in the United States. Chi square analysis was used to determine differences in responses to questions between Swedish and American orthodontists. P

DENTAL surgeries have been told to remove magazines and toys from their waiting rooms

DENTAL surgeries have been told to remove magazines and toys from their waiting rooms to help halt the spread of swine flu.
The Evening News has discovered every NHS practice has been sent the new guidance as health chiefs battle to control the spread of the H1N1 virus.

The move has been met with a mixed reaction, with some branding it a step too far – arguing that there are other more dangerous risks of swine flu spreading – while others insist it is merely a sensible measure.

It is understood the Lothian board is one of the first health authorities in the country to implement the guidelines, though dentists can ultimately choose to ignore them.

And it is not clear whether the moves will be extended to GP surgeries, with the British Medical Association saying that it had not been made aware of similar advice.

One dentist based in West Lothian told the Evening News: "We're not convinced.

"If you start taking magazines away then you'll have to stop people touching door handles and make sure they wash their hands thoroughly before coming back from the toilet.

"It certainly wouldn't be 100 per cent effective, and you can hardly stop people bringing in their own magazines to read and then leaving them."

Another city-based dentist added: "Perhaps it's quite a sensible thing, sometimes you see big boxes of toys which won't have been cleaned for ages."

It is thought that even once the swine flu outbreak passes, it is likely the advice will remain to reduce the spread of other bugs.

More than 1,000 people reported to their GP last week with symptoms of flu in the Lothians, and that figure is expected to rise as the temperature continues to plummet.

Dr Marion Storrie, clinical director of Lothian Unscheduled Care Service for NHS Lothian, confirmed the letters had been sent out.

She said: "This guidance was issued to general dental practitioners, advising them that they may wish to consider removing items such as toys and magazines from their waiting area to reduce the spread of the virus."

NHS Lothian already has significant contingency plans in place to tackle swine flu, and the vaccination of the 200,000 at-risk individuals and key frontline healthcare workers has begun.

While swine flu remains a reasonably tame strain of influenza, health chiefs are keen to eliminate the risk of catching it, particularly from healthcare premises

Margaret Watt, chairwoman of the Scotland Patients' Association, said: "We fully support NHS Lothian on this, and would urge them to move it on from just a request.

"It has long been known paper is a carrier of infection, especially second-hand. Years ago comics that were sent to infection hospitals used to go straight into the furnace, they knew even then of the dangers."

Several mechanisms have been purported to describe how mouthguards protect the orofacial complex against injury. As the properties needed for these mechanisms to be effective are temperature and frequency dependent, the specific aim of this study was to provide a comprehensive thermal characterization of commercial mouthguard materials.

Five commercially representative thermoplastic mouthguard materials (Essix™ Resin, Erkoflex™, Proform™-regular, Proform™-laminate, and Polyshok™) were tested. Differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA) techniques were implemented to measure thermal transitions and mechanical properties. Measurements were conducted three times per sample. One-way ANOVA and one-sample t-tests were used to test for differences between commercial products on selected mean thermal property values.

The DSC measurements indicated no differences between commercial materials for mean glass transition (p=0.053), onset melt (p=0.973), or peak melt (p=0.436) temperatures. Likewise, DMA measurements revealed no differences between commercial materials for the mean glass transition (p=0.093), storage modulus (p=0.257), or loss modulus (p=0.172) properties, respectively. The one-sample t-tests revealed that glass transition temperatures were different from intra-oral temperature (p<0.005) for all materials.

Commercialized mouthguard materials are sensitive to repetitive heating and cooling cycles, prolonged thermal treatment, and have glass transitions well below their end-use intra-oral temperature. As such, these materials are functioning as elastomers and not optimal mechanical damping materials. Dental clinicians, healthcare practitioners, or end-users should be aware that these materials are at best problematic with respect to this protective mechanism.
