Gum Disease-causing Bacteria Linked to Pancreatic Cancer, Study

wpid Gum Diseasecausing Bacteria Linked to Pancreatic Cancer Study Gum Disease causing Bacteria Linked to Pancreatic Cancer, StudyAccording to a recent study, Granulicatella adjacens, along with other bacteria involved in gum disease, may be linked to pancreatic cancer. The study is highlighted in the online edition of the journal Gut with the abstract of the article found on Pubmed (

By way of a short course on microbiology, two streptococcus varieties: streptococcus adjacens and streptococcus defectives, were initially defined by Bouvet in 1989 (Bouvet, et al, 2989).  With the use of 16S rRNA gene sequencing that later became available these bacteria were then named Abiotrophia adiacens and Abiotrophia defective in 1995 and later Granulicatella adjacens in 2000 (Collins and Lawson). full.  These two strep varieties are among many that have also been linked to gum disease. It is reported that 16S rRNA gene sequencing is the technique of choice for identifying G. adiacens and A. defectiva, and incidentally, early surgical intervention should be considered when G. adiacens endocarditis is diagnosed.

As the authors of the published study note, an association between pancreatic cancer risk and oral bacteria has been established by a number of prospective cohort studies. This study measured variations in oral microbiota and in three arms sought to access their relationship to pancreatic cancer and pancreatitis. The first phase of the study used microbiological profiling using a salivary assay (the Human Oral Microbe Identification Microarray) to look for variations between oral bacteria in 10 resectable pancreatic cancer patients and 10 controls. In the second phase the authors used quantitative analysis (qPCR) to define the types of bacteria, and the third phase involved bacterial validation via the use of qPCR for 28 resectable, 28 healthy, and 28 pancreatitis patients.

What JJ Farrell and colleagues from the UCLA David Geffen School of Medicine, California, USA, found was a significant variation between cancer patients and controls with 31 bacterial species/clusters found in the saliva having increased and 25 decreased. Two bacteria: neisseria elongata and streptococcus mitis were validated and were significantly different between pancreatic cancer patients and controls and two bacteria: granulicatella adjacens and S mitans showed signficant variation between chronic pancreatitis samples and controls.

Although the study sample was small and association does not equate with causation, the authors report that their study could open the door for new treatment options for pancreatic cancer. The latter has been recognized among the very difficult cancers to treat and this study suggests that this could be changed by disturbing the bacterial balance (if the bacteria are contributing to disease rather than arising secondary to disease).

Of more importance presently, the authors conclude that monitoring the concentrations of certain types of bacteria might be useful in detecting pancreatic cancer. Such an approach would be helpful in diagnosing this type of cancer which is characterized by its unclear signs.

Many Young Children Off To A Poor Start With Dental Health, According To Poll Results

wpid Many Young Children Off To A Poor Start With Dental Health According To Poll Results Many Young Children Off To A Poor Start With Dental Health, According To Poll Results

Article Opinions: 1 posts
Although child health experts recommend that children begin oral health care by age 1 or when their first teeth emerge, a new report from the C.S. Mott Children’s Hospital National Poll on Children’s Health shows that most children ages 1-2 have not yet started seeing a dentist.

In May 2011, the National Poll on Children’s Health asked parents of children ages 1-5 about dental health care for young children. The poll found that only 23% of 1-year-olds had been to the dentist and only 44% of 2-year-olds had been to the dentist.

“Dental problems such as early childhood caries (cavities in the baby teeth) are the leading cause of chronic disease for young children,” says Sarah Clark, M.P.H., Associate Director of the Child Health Evaluation and Research (CHEAR) Unit at the University of Michigan. “Most dental problems can be prevented through good oral health care.”

Parents may not be aware of recommendations for early dental health care and finding a dentist who will see young children especially those covered by Medicaid is a long standing problem in some communities. To address these issues, pediatricians and health care providers are now seen as important partners in oral health and are encouraged to discuss oral health during well-child visits.

“Well-child visits are critical to making sure that parents understand their role in preventing dental problems, such as how to clean the child’s baby teeth and the importance of avoiding sugary beverages and bottles in the crib,” says Clark. “Well-child visits are also a key opportunity for a health professional to examine the child’s baby teeth and make sure that children with early signs of decay are strongly encouraged to see a dentist.”

However, when parents of 1-2 year olds were asked about dental health activities that occurred at their child’s most recent well-child visit, less than half of parents said their health care providers talked to them about cleaning the teeth or taking their child to the dentist and 1 in 3 children did not have their teeth examined at all by their health care provider.

“We know that not all children will see a dentist at age 1, but on the other hand, almost all children have well-child visits with a pediatrician or other health care provider,” Clark continues. “The results of this poll indicate that we need to improve the way oral health issues are addressed during well-child visits so that parents fully understand the need for good oral health care.”

Fixed Appliances Best And Cheapest To Correct Crossbite In Children

wpid Fixed Appliances Best And Cheapest To Correct Crossbite In Children Fixed Appliances Best And Cheapest To Correct Crossbite In Children5 (1 votes)

Society could save millions of crowns each year if more children were fitted with fixed appliances. This is shown in unique studies performed by Sofia Petrén, a dentist and orthodontic specialist at the Department of Orthodontics at Malmo University in Sweden.

Calculations indicate that at least ten percent of all eight- and nine-year-olds in Sweden have so-called crossbite.

This means that the children’s upper and lower jaws are different in width and do not line up against each other when they bite their jaws together. If this problem is not corrected, the children can experience pain in the jaw, facial muscles, and jaw joints. Their face can also become asymmetrical.

In randomized studies, Sofia Petrén investigated four methods of treatment: fixed appliance (Quad Helix), removable appliance (expansion plate), composite construction on the molars of the lower jaw, and no action in the hope that the problem will straighten itself out. A total of 70 children were involved in the four groups.

The results show that neither the composite construction nor no action has any effect on crossbite. The other two treatments are effective, both in the short and long term, but the fixed appliance yielded clearly superior results.

“The fixed appliance entail that the children are treated 24 hours a day. The removable plate means that the children need the help of their parents, and it happens that they forget it sometimes, which affects the outcome of treatment,” says Sofia Petrén.

There’s a big difference in the cost of the various treatment methods, both direct and indirect, according to Sofia Petrén, who arrived at these results in her dissertation Correction of Unilateral Posterior Crossbite in the Mixed Dentition, submitted to the Faculty of Odontology at Malmö University.

The fixed appliance is also the cheapest. Sofia Petrén compared the costs, both direct and indirect, and found that society could save SEK 32 million per year if all children with unilateral crossbite were treated with fixed braces. Part of the difference is due to the fact that children who are treated with removable appliances sometimes need to be treated again because the treatment failed.

But even if all treatments with removable appliances were successful, the annual cost would still be more than SEK 12 million compared with fixed braces.

“Today both treatments are equally common in clinics, but I maintain we should use the method that works best, has a lasting effect, and is most cost-effective.”

Even though orthodontic appliances have been used for more than 100 years, the scientific evidence for different treatments is very patchy, something that SBU, the Swedish Council on Health Technology Assessment, drew attention to in a 2005 report.

Sofia Petrén’s dissertation fills a gap in our knowledge that will probably lead to changes in treatment routines. The finding that children’s bite problems do not sort themselves out spontaneously means that county councils that postpone treatment to save money will be facing even higher costs in the long run.

“When children are treated in their teens, the treatment is more complicated and costly,” says Sofia Petrén, who wants to study how children’s quality of life is affected during and after treatment.

IADR/AADR Publish Study On Dental Caries Vaccine

wpid IADRAADR Publish Study On Dental Caries Vaccine IADR/AADR Publish Study On Dental Caries Vaccine5 (1 votes)

In a report on a preclinical investigation titled “Flagellin Enhances Saliva IgA Response and Protection of Anti-caries DNA Vaccine,” lead author Wei Shi, Wuhan Institute of Virology, Chinese Academy of Sciences, and his team of researchers demonstrate that anti-caries DNA vaccines, including pGJA-P/VAX, are promising for preventing dental caries. However, challenges remain because of the low immunogenicity of DNA vaccines. This study is published in the Journal of Dental Research, the official publication of the International and American Associations for Dental Research (IADR/AADR).

In this study, Shi and team used recombinant flagellin protein derived from Salmonella as mucosal adjuvant for anti-caries DNA vaccine (pGJA-P/VAX) and analyzed the effects of Salmonella protein on the serum surface protein immunoglobulin G and saliva surface protein immunoglobulin A antibody responses, the colonization of Streptococcus mutans (S. mutans) on rodent teeth, and the formation of caries lesions. The results showed that Salmonella promoted the production of surface protein immunoglobulin G in serum and secretory immunoglobulin A in saliva of animals by intranasal immunization with pGJA-P/VAX plus Salmonella.

Furthermore, Shi found that enhanced surface protein immunoglobulin A responses in saliva were associated with inhibition of S. mutans colonization of tooth surfaces and endowed better protection with significant less carious lesions. In conclusion, the study demonstrates that recombinant Salmonella could enhance specific immunoglobulin A responses in saliva and protective ability of pGJA-P/VAX, providing an effective mucosal adjuvant candidate for intranasal immunization of an anti-caries DNA vaccine.

Daniel Smith, The Forsyth Institute, wrote a corresponding perspective article in response to the Shi et al report titled “Prospects in Caries Vaccine Development.” In it, he states that DNA vaccine approaches for dental caries have had a history of success in animal models. Dental caries vaccines, directed to key components of S. mutans colonization and enhanced by safe and effective adjuvants and optimal delivery vehicles, are likely to be forthcoming.

“These papers highlight the exciting potential of using vaccines to protect against dental caries,” said JDR Editor-in-Chief William Giannobile. “This research is promising and provides optimism to help promote public health of caries-susceptible individuals.”

Premature Children Have Smaller Teeth

wpid Premature Children Have Smaller Teeth Premature Children Have Smaller Teeth

The size of teeth in premature children is smaller. This has been established in a study from the Faculty of Odontology at Malmö University in Sweden.

Our knowledge about premature children, and their physical and mental development as they grow up, is constantly growing. In recent years several studies of children’s dental health have been published by researchers at the Faculty of Odontology in Malmö. Liselotte Paulsson-Björnsson, a specialist in orthodontics, has studied 80 children born before week 33 of pregnancy.

“We have examined how their teeth are developing and, among other things, we’ve looked at their bites. We’ve also checked their need for orthodontic adjustments and found that it is greater than in the control group, children born at full term,” she says.

The children participating in the various studies were born in the mid 1990s and were examined when they developed their first permanent teeth at the age of eight to ten. The first permanent teeth are the front teeth in the upper and lower jaw and the so-called six-year molars, the first big molars.

The results show that the teeth of premature children were up to ten percent smaller compared with the control group. The earlier the children were born the smaller their teeth were.

“When we examined the children we also saw that their teeth were farther apart,” says Liselotte Paulsson-Björnsson, who stresses that having small teeth as such is not a serious problem, but it can be aesthetically problematic to have large gaps between your teeth.

“But these problems can be addressed. We can move teeth if the gaps between them are too large, and there is also good material to extend teeth if they’re too small.”

Disturbances in the teeth’s mineralization phase can also lead to spots on the front teeth, but this is also a problem that can be dealt with using cosmetic dental treatments.

Liselotte Paulsson-Björnsson is now planning new studies to follow these children into their teens. Among other things, she will be studying whether all permanent teeth are affected in terms of size, or only the ones that are formed in connection with birth. She also wants to study the children’s quality of life in relation to their dental status.

“But as care of premature children is under constant development, it’s not possible to automatically transfer my findings to children being born prematurely now,” she says.

British Dental Association Says Promises To Protect Patient Care Not Being Kept

wpid British Dental Association Says Promises To Protect Patient Care Not Being Kept British Dental Association Says Promises To Protect Patient Care Not Being Kept

According to an investigation by the British Dental Association (BDA), NHS dental care across the UK for vulnerable individuals is suffering due to financial pressures, leaving dentists concerned they will be unable to maintain the services they provide to their patients against a tide of decline and neglect.

In a survey, which examined dentists that focus on treating special care patient groups, two-thirds who responded stated that they are increasingly worried as dental posts have been lost or not replaced due to reorganization or budget cuts. And nearly the same number of those who responded explained that equipment is not being replaced.

Concerns regarding the effect on patients were clear. 83% of those surveyed believed patients were having to wait longer for treatment, 72% said the range of services being provided was being reduced and 58% felt the quality of services was suffering.

The BDA has written to the Department of Health, highlighting the worries raised by the survey and asking them to stress to Primary Care Trusts that financial cuts to services are not acceptable.

Dr Peter Bateman, Chair of the BDA’s Salaried Dentists Committee, explained:

“This survey confirms fears that Government promises to protect frontline patient care are not being delivered on by PCTs. It paints a picture of vacancies not being filled, equipment not being replaced and increased waiting times for patients.

We understand that economic circumstances mean that tough choices must be made about the use of a finite pot of money, and allowing services for the vulnerable minority to falter may look like an easy option because these individuals are often less able to speak up for themselves, but salaried primary care dentists will not tolerate misguided decisions to put money before care for these patients.

That’s why we’re highlighting these problems now and demanding urgent action. Primary Care Trusts must be reminded of the Government’s promise to protect frontline care and play their part in ensuring it is kept. If they fail to do so, our fear is that services will simply disintegrate, and by the time the National Commissioning Board assumes its responsibilities, primary salaried dental care will be a pale shadow of the service it is now.”

Dubai to Open Two New Dental Clinics

wpid Dubai to Open Two New Dental Clinics Dubai to Open Two New Dental ClinicsThe Dubai Health Authority (DHA) has decided to stop providing dental services at a facility in Al Rashidiya. This facility is one of the oldest dental centers in Dubai. Instead, DHA will be opening 2 new public dental clinics at Nad Al Hammar and Al Mizhar health centers. The new dental clinics represent a step in UAE’s long-term expansion plans for health services.

The clinics will provide primary and specialized dental services to the residents in Dubai. The clinics started their operations this week. With the addition of the two new clinics, the number of government-run dental facilities will now be fourteen. Opening the new dental clinics comes as a means of coping with the demand for dental services in Dubai, which has increased during the last decade.

Public health experts say that the number of dental conditions such as tooth decay and periodontits has been rapidly increasing, particularly among children. DHA and other health authorities have started a plan to improve dental services by establishing more dental clinics and starting universal dental health care plans. Current statistics suggest that over 100,000 patients were seen in clinics during the past year and the addition of two new clinics should allow an even greater number of patient examinations in the years to come.
