Bacteria from patient's dental plaque causes ventilator-associated pneumonia

BUFFALO, N.Y. -- Patients admitted to a hospital's intensive care unit (ICU) already are seriously ill, so the last thing they need is a new infection. Unfortunately, statistics show that as many as 25 percent of all patients admitted to the ICU and placed on ventilators develop pneumonia, which can be fatal.

Ventilator-associated pneumonia is a major cause of infection in the hospital, and studies have shown that this infection can add $40,000 to costs and double the length of stay of the patient in the hospital.

Ironically, it turns out that the patient’s own dental plaque is a major source of germs that cause ventilator-associated pneumonia.

In results to be presented today (March 23, 2007) at the International Association of Dental Research (IADR), researchers from the University at Buffalo School of Dental Medicine show that the same bacteria identified in dental plaque of patients when they were admitted to the ICU and placed on ventilators were found later in the lungs from those who subsequently developed pneumonia.

"Our study shows that a strong relationship exists between oral and respiratory pathogens in patients with ventilator-associated pneumonia," said Paul Heo, D.D.S., a doctoral student in the UB dental school’s Department of Oral Biology and first author on the study.

"We are saying that if the patients’ mouths and teeth aren’t cleaned while they are in the hospital, they may easily develop lung disease."

The presentation is part of a three-year longitudinal, double-blind study funded by the National Institute of Dental and Craniofacial Research and headed by Frank A. Scannapieco, D.D.S., Ph.D., professor and chair of the Department of Oral Biology.

The trial aims to determine if swabbing ventilated ICU patients’ mouths with a bactericide protects them from developing pneumonia.

In this component, Heo and colleagues concentrated on three strains of suspected pathogens that are responsible for most hospital-acquired pneumonia: Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. Samples of plaque from teeth and of secretions from the trachea were obtained from ICU patients on the day of admission and every third day thereafter, up to 21 days. Bronchial alveolar lavage samples also were collected from those suspected of having developed pneumonia.

Samples from nine patients who were found to have the pathogens of interest in their plaque and were suspected of having pneumonia were selected for analysis. Protein and DNA profiles of pathogens in plaque and in bronchial alveolar lavage samples were identified using a process called pulsed-field gel electrophoresis.

Results showed that genetic profiles of bacteria from tracheal and bronchial samples of the nine patients with pneumonia were identical to profiles of bacteria from their dental plaque.

"These results suggest that the teeth likely serve as an important reservoir of infection in these patients," said Heo. "To prevent opportunistic, hospital-acquired disease, taking care of teeth and gums while hospitalized might be especially important."

'Ancestral Eve' was mother of all tooth decay

NYUCD study finds humans and their oral bacteria evolved from a common African ancestor

A New York University College of Dentistry (NYUCD) research team has found the first oral bacterial evidence supporting the dispersal of modern Homo sapiens out of Africa to Asia.

The team, led by Page Caufield, a professor of cariology and comprehensive care at NYUCD, discovered that Streptoccocus mutans, a bacterium associated with dental caries, has evolved along with its human hosts in a clear line that can be traced back to a single common ancestor who lived in Africa between 100,000 and 200,000 years ago.

S. mutans is transmitted from mothers to infants, and first appears in an infant’s mouth at about two years of age. Caufield’s findings are reported in an article in the February issue of the Journal of Bacteriology.

In his analysis of the bacterium, Caufield used DNA fingerprints and other biomarkers that scientists have also employed to trace human evolution back to a single common African ancestor, known as "ancestral Eve."

"As humans migrated around the world and evolved into the different races and ethnicities we know today," Caufield said, "this oral bacterium evolved with them in a simultaneous process called coevolution."

"It is relatively easy to trace the evolution of S. mutans, since it reproduces through simple cell division," says Caufield, who gathered over 600 samples of the bacterium on six continents over the past two decades. His final analysis focused on over 60 strains of S. mutans collected from Chinese and Japanese; Africans; African-Americans and Hispanics in the United States; Caucasians in the United States, Sweden, and Australia; and Amazon Indians in Brazil and Guyana.

"By tracing the DNA lineages of these strains," Caufield said, "We have constructed an evolutionary family tree with its roots in Africa and its main branch extending to Asia. A second branch, extending from Asia back to Europe, traces the migration of a small group of Asians who founded at least one group of modern-day Caucasians."

Additional branches, tracing the coevolution of humans and bacteria from Asia into North and South America, will be drawn in the next phase of Caufield’s analysis.

NHS Dental Contract Attacks Mount

Even the UK dentists have their own insurance problems:

People are finding it no easier to see an NHS dentist a year after radical reforms of NHS dentistry came into effect, according to two reports.

A British Dental Association poll of 394 dentists found the majority did not think the reforms had improved access.

And Citizens Advice said 2m patients did not have access to an NHS dentist and were being forced to go private, go on waiting lists or do without.

However, the government said improvements were being made.

Scientists Regrow Dental Enamel from Cultured Cells

I started hearing about this over 10 years ago at the first Internet Dental Forum meeting at the National Institute of Health.

Dental enamel is the hardest tissue produced by the body. It cannot regenerate itself, because it is formed by a layer of cells that is lost by the time the tooth appears in the mouth. The enamel spends the remainder of its lifetime vulnerable to wear, damage, and decay. For this reason, it is exciting to consider the prospect of artificially growing enamel, or even whole teeth, using culturing and transplantation techniques. In the emergent field of tooth-tissue engineering, several groups have developed their own approaches. Although there has been some success in producing enamel-like and tooth-like tissues, problems remain to be solved before the technology comes close to being tested in humans. One of the issues has been how to produce, in culture, sufficient numbers of enamel-forming cells. During the 85thth General Session of the International Association for Dental Research, a team of researchers from the Institute of Medical Science, the University of Tokyo (Japan), reported on a new technique for culturing cells that have the capacity to produce enamel. This group has recently shown that epithelial cells extracted from the developing teeth of 6-month-old pigs continue to proliferate when they are cultured on top of a special feeder layer of cells (the feeder-layer cells are known as the 3T3-J2 cell line). This crucial step boosts the number of dental epithelial cells available for enamel production. In the study being reported today, the researchers seeded the cultured dental epithelial cells onto collagen sponge scaffolds, along with cells from the middle of the tooth (dental mesenchymal cells). The scaffolds were then transferred into the abdominal cavities of rats, where conditions were favorable for the cells in the scaffolds to interact and develop. When removed after 4 weeks, the remnants of the scaffolds were found to contain enamel-like tissue. The key finding of this study was that even after the multiple divisions that occurred during propagation of the cells in culture, the dental epithelial cells retained the ability to produce enamel, as long as they were later provided with an appropriate environment. The idea for the culturing technique originates from 1975, when Dr. J.G. Rheinwald and Dr. H. Green of Harvard Medical School reported the use of feeder layers for culturing epithelial cells from the skin (the 3T3-J2 cells used in the current study were gifted by Dr. Green). The cell-scaffold approach is based on tissue-engineering technology developed at the Forsyth Institute (MA) and was applied by one of the Tokyo researchers to produce enamel-like tissues in 2002. Now that dental epithelial cells can be propagated in culture, the next step will be to achieve the same success with their partners in tooth formation, the dental mesenchymal cells. Further development of this technique will be aimed toward production of tissue to replace damaged or missing enamel, and ultimately, regeneration of whole teeth.

New approaches to the diagnosis of oral cancer

Oral cancer is diagnosed in more than 30,000 individuals in the US annually, claiming 10,000 lives each year. Early detection remains the best way to ensure patient survival and quality of life. Today, during the 85th General Session of the International Association for Dental Research, scientists from the University of California-Irvine present two novel, non-invasive, ultra-fast imaging approaches to oral cancer detection, diagnostic screening, and mapping.

More than 2/3 of all oral cancer cases documented by the National Cancer Institute are diagnosed at an advanced stage. The five-year survival rate is 75% for those with localized disease at diagnosis, but only 16% for those with cancer metastasis. Earlier detection of oral lesions would greatly improve the prognosis of these patients. Accurate delineation of lesion margins would ensure effective removal of all the tissue that presents a threat to the patient’s long-term health. Two basic facts indicate that early detection of oral malignancy should be possible to a far greater extent than is currently seen: (1) Accounting for 96% of all oral cancers, squamous cell carcinoma is often preceded by lesions on the oral mucosa. Malignant transformation, which is quite unpredictable, occurs in 1-90% of lesions over five years. Thus, oral cancer is often preceded by lesions which are visible to the naked eye prior to transformation. A non-invasive diagnostic modality would permit regular monitoring of these lesions, detection of lesion transformation, and the identification of treatment needs at a very early, relatively harmless stage. (2) High-risk populations are clearly defined: tobacco use, alcohol abuse, urban environment, specific ethnicities, poor diet, and frequent exposure to sunlight. A fast, mobile, relatively inexpensive and non-invasive diagnostic modality would permit the early detection and monitoring of oral lesions.

The researchers describe Three-dimensional Optical Coherence Tomography (3-D OCT) and Optical Doppler Tomography (ODT), which show surface and subsurface tissues at near-microscopic levels of resolution, with the potential for replacing conventional surgical biopsy and histopathology techniques. Combined with polarimetry, accurate delineation of lesion margins becomes possible. Scanning is painless and non-invasive, lasting less than one minute with a pen-sized hand-held probe. This device’s resolution or diagnostic capability may dictate its primary use as an indicator of the need for biopsy. Later, this modality may progressively reduce the need for biopsy, define surgical margins, and permit the direct evaluation of cancer treatments. In combination with OCT-visible molecular probes, this modality will greatly advance cancer diagnostics.-International & American Association for Dental Research

Using Dental X-rays to Detect Osteoporosis

Researchers in the Academic Center for Dentistry Amsterdam have created a unique way of identifying patients at risk of osteoporosis by using ordinary dental x-rays. Professor Paul F. van der Stelt and his team developed the largely automated approach to detecting the disease during a three-year, EU-funded collaboration with the Universities of Manchester, Athens, Leuven, and Malmö. They will present their findings today during the 85th General Session of the International Association for Dental Research.

In four clinical centers, 671 women with an average age of 55 years were recruited. To obtain the "gold standard", the team measured bone thickness at the femur, hip, and spine, using the technique that is common for this kind of expensive examination (Bone Mass Density, BMD). In addition, one panoramic and two intra-oral radiographs were made.

By analyzing a small area depicting the trabecular bone on the ordinary dental radiographs, dentists can predict the osteoporotic condition of the patients to the same extent as the BMD measurements.

The image analysis can be automated and does not require extra time on the part of the dentist. The newly developed technique means that patients who are identified as being at risk can be referred for more thorough appropriate examinations.

New Saliva Test May Help Dentists Test for Breast Cancer

From The Academy of General Dentistry web site.

CHICAGO (March 16, 2007) –Breast cancer is the second leading cause of death among women in the United States. In 2006, the American Cancer Society estimated that there would be 212,920 new cases of invasive breast cancer, and in that year, 40,970 women would die from it. Many women’s lives could be saved if this cancer was diagnosed earlier, and early diagnosis could be achieved if there were more and easier opportunities to do so.

Sebastian Z. Paige and Charles F. Streckfus, DDS, MA, the authors of the study, “Salivary analysis in the diagnosis and treatment of breast cancer,” published in the March/April 2007 issue of General Dentistry, the Academy of General Dentistry’s (AGD) clinical, peer-reviewed journal, researched a new method of diagnosis.

They found that the protein levels in saliva have great potential to assist in the diagnosis, treatment, and follow-up care of breast cancer. And general dentists are perfect candidates to assist with this diagnosis samples because they can easily remove saliva samples from a patient’s mouth during routine visits. As the AGD’s Vice-President Paula Jones, DDS, FAGD says, “Since a patient visits the dentist more frequently than their physician, it makes sense that this diagnostic tool could be very effective in the hands of the general dentist.”

Salivary testing has some advantages over blood testing. The authors of the study argue that saliva is a clear, colorless liquid, while blood undergoes changes in color, which might affect test results. The authors also say that saliva collection is safe (no needle punctures), non-invasive, and can be collected without causing a patient any pain.

This method of early diagnosis is not yet approved by the Food and Drug Administration (FDA). If it does receive approval, dentists and physicians could use it to collaboratively diagnose breast cancer.

But Dr. Jones also warns that this is not the only means for diagnosis. “It would not eliminate the need for regular mammogram screening or blood analysis; it would just be a first line of defense for women,” she says. “For example, if the salivary screening did show a positive result, a mammogram or other imaging test would be necessary to determine in which breast the cancer was located.”

Advantages of salivary testing:

  • Salivary testing is safe (no needle punctures) and can be collected without causing the patient any pain.
  • Salivary testing does not require any special training or equipment.
  • Patients who may not have access to or money for preventive care could easily be tested through saliva.

Why Backups Are Important

Perhaps you know that sinking feeling when a single keystroke accidentally destroys hours of work. Now imagine wiping out a disk drive containing information for an account worth $38 billion.

That's what happened to a computer technician reformatting a disk drive at the Alaska Department of Revenue. While doing routine maintenance work, the technician accidentally deleted applicant information for an oil-funded account — one of Alaska residents' biggest perks — and mistakenly reformatted the backup drive, as well.

There was still hope, until the department discovered its third line of defense, backup tapes, were unreadable.

Read the whole story here.

Don't think this cannot happen in a dental office. OOPS! is one of the big reasons for loss of data. Tape backups are unreliable. Having a good backup and restore plan in place is absolutely necessary. Loss of data is not covered under an insurance policy and can cost your office lots of money.

IDA President Advocates Doing Away with Clinical Boards

Dr. Tom Grimes, President of the Iowa Dental Association, has asked that the following excerpt from his President's message that will appear in the April issue of the Iowa Dental Journal be sent out via this medium -- partly because it gives the membership an avenue to respond or comment immediately.

"Included in this month's (April 2007) issue of the Journal is an important and timely original study entitled, "Association between performance on dental licensure examination and faculty evaluations of clincial competence at graduation". This article concludes that over a 7-year period "the clinical competency of students who failed the CRDTS examination was essentially the same as the clinical competency of those who passed the examination". Thus, the CRDTS examination does not appear to be a very useful instrument in distinguishing between competent and incompetent practitioners among graduating senior dental students.

The article is timely because nationally, dental licensure is in a state of flux. Debate continues over the development of a uniform examination and over the use of human subjects on licensure exams. It can be challenging for dental students to obtain current examination requirements from state boards as a result of the competing national and regional clinical licensure examinations.

New York has eliminated the clincial exam as a requirement for initial licensure effective 2007. Some states offer the option of completing a residency or passing a clinical exam (California, Connecticut, and Minnesota). I favor licensure for all U of I College of Dentistry graduates, with or without a clinical exam or a one-year residency program, if they practice in Iowa. Changes such as this can be done on a state-to-state basis. Dental boards in 46 states grant licenses to dentists currently licensed and in active, continuous practice for a specific period of time (typically 5 years) without further theoretical or clinical examinations."

New NanoTite Implant From 3i

Biomet, Inc. has announced that Biomet 3i, the Company's dental reconstructive device subsidiary, has introduced a new dental implant that utilizes nanotechnology. The NanoTite Implant builds upon the benefits of Biomet 3i's OSSEOTITE Implant by adding deposits of nano-scale calcium phosphate crystals to approximately 50% of the surface. According to pre-clinical studies, these nano-scale deposits create a complex surface on the implant that appears to play a key role in how the implant bonds with the bone. Human bone recognizes calcium phosphate as biologically natural, allowing the bone and implant to bond during healing.

Dental implants replace single or multiple missing teeth due to cavities, decay, trauma or disease and are designed to help preserve bone structure and natural facial contours. The 2007 dental reconstructive device market is estimated to be approximately $625 million in the United States and exceeds $2 billion worldwide, growing at an annual rate of 15-17%.

Aspirin Withdrawal and Risk of Myocardial Infarction

It has been reported that patients with acute coronary syndrome (ACS) who
were previously on aspirin therapy but had discontinued aspirin use had
worse short-term outcomes than individuals not previously on aspirin therapy
(Collett JP, et al. Circulation 2004; 110:2361-2367). Also, researchers
have reported that discontinuation of aspirin by daily aspirin users may
increase the risk of myocardial infarction. (Fischer LM et al. Arch Intern
Med, 2004, 164: 2472-2476). A Harvard Health Letter (volume 30:6, 2005)
also stated that quitting aspirin "cold turkey" could be dangerous and that
studies have linked aspirin withdrawal with heart attacks. Researchers have
showed that the risk of acute myocardial infarction (AMI) was one and one
half times greater for subjects who stopped taking non-steroidal
anti-inflammatory drugs (NSAIDs) including aspirin from 1 to 29 days
compared to non-users.

The study by Collett et al stated that temporary withdrawal of aspirin is
common and acute rebound effect with coronary thrombosis is a suspected
result of the withdrawal.

ALSO, in a statement released on Sept. 8, 2006 the FDA notified consumers
and health care professionals that the administration of ibuprofen for pain
relief to patient taking aspirin for cardioprotection may interfere with
aspirin's cardiovascular benefits. The FDA states that ibuprofen can
interfere with the antiplatelet effect of low-dose aspirin (81 mg daily).
this could result in diminished effectiveness of aspirin as used for
cardioprotection and stroke prevention.

Recommendations -

1. Patients who use immediate release aspirin (not enteric coated aspirin)
and take a single dose of ibuprofen 400 mg should dose the ibuprofen at
least 30 minutes or longer after aspirin ingestion to avoid attenuation of
aspirin's effect.

2. At this time, recommendations about the timing of ibuprofen 400 mg in
patients taking enteric-coated low dose aspirin cannot be made based on
available data. One study, however, showed that the antiplatelet effect of
enteric-coated low dose aspirin was attenuated when ibuprofen 400 me was
dosed 2, 7, and 12 hours after aspirin (Catella-Lawson et al. NEJM 2001;

3. Acetaminophen appears to not interfere with the antiplatelet effect of
low dose aspirin.

4. Other OTC NSAIDs (naproxen sodium and ketoprofen) should be viewed as
having the potential to interfere with the antiplatelet effect of low-dose
aspirin until proven otherwise. The FDA is unaware of any studies that have
looked at the same type of interfer4rence by ketoprofen with low-dose

From the press release:

Milestone Scientific, Inc. (OTCBB: MLSS), a world leader in computer controlled local anesthetic delivery, will officially unveil its highly anticipated Single Tooth Anesthesia (STA) System during this year’s Chicago Dental Society Midwinter Meeting. Milestone will be conducting demonstrations of the STA System at booth # 2206.

The FDA-cleared STA System is comprised of a computer-controlled drive unit and a single-use disposable handpiece/needle assembly. It provides newly-patented real-time visual and audible feedback and verbal announcements via Milestone Scientific’s patented CompuFlo™ with Dynamic Pressure Sensing (DPS™) technology, thus taking the guesswork out of the administration of anesthetic.

Specifically, the STA System enables the dental professional to precisely administer an intraligementary injection to anesthetize a single tooth in only one to two minutes*, rather than administering a mandibular block that anesthetizes an entire quadrant. The STA Intraligamentary injection has an immediate onset, whereas the typical block injection can take 8 to 12 minutes before a dentist can start treatment. In addition, the STA intraligementary injection last as long as a traditional infiltration or mandibular block. All of this is accomplished with a technology that has been clinically proven to provide a pain-free injection.

* Using 4% Articaine Hydrochloride 1:200,000 local anesthetic solution.

Using the innovative CompuFlo with DPS technology, the STA System informs the clinician of the exact location of the needle point between the tooth and bone to directly target the periodontal ligament in order to comfortably anesthetize a single tooth without causing collateral numbing of the cheek, lips and tongue or histological damage commonly associated with the traditional PDL injection.

Moreover, the STA System has been programmed to measure the precise “exit pressure of an anesthetic as it is injected into tissues of varying density. It provides constant information so that the dental professional is in the optimal location during the entire injection.

Furthermore, unlike traditional syringe injections, the STA System allows the dental professional to start working immediately after the injection is administered, resulting in definitive and uninterrupted treatment saving valuable chair time. It also allows work to be performed in multiple quadrants and in both arches with ease, precision and efficiency, thus allowing multiple procedures to be completed in a single office visit.

The STASystem incorporates Milestone’s CompuDent technology which was introduced in 1998 and marked the first major advancement in local anesthetic delivery since the syringe was invented more than 150 years ago. Milestone’s STA System is well-positioned to make a significant and positive impact on the predictability and productivity of the dental practice while improving the overall patient experience, by eliminating collateral anesthesia with a pain-free injection.

A New Tablet PC

It will not run Dental Practice Management software but hopefully we can get something like this in the future.

Emano Tec, Inc., a Waban, Massachusetts firm, is introducing a medical tablet that weighs under a pound, sports an 8-hour battery life, and is touted to sustain "a 3-foot drop onto concrete without damage."

The following are from the company:

Unlike PDA or Ultra PCs, MedTab offers the screen size and resolution necessary to view and update EMRs. Unlike Tablet PCs, MedTab is small and light enough to carry in a lab coat pocket.

Beyond this, MedTab will last a whole shift (12 hours) without recharging, is rugged and can be disinfected. MedTab offers the possibility of a single sign-on system since its software configuration and provisioning are controlled by the IT department and not the end user.

MedTab is lockdown and as such, the end user can not configure or modify its software or use it for any purpose other than what the IT department has configured it for. MedTab is easily provisioned remotely over a secure, wired LAN line or wirelessly over state of the art 802.11 security protocols which is configure remotely.

A stolen device represents little risk to security since the system is locked down, and it's possible to monitor its position and know if it's leaving

The Next Smartphone?

Here is a link to an Palm Addicts interview with Jeff Hawkins the inventor of the Palm Pilot and Treo. It seems the mysterious 3rd business of Palm and its product will be exposed very shortly.

Here is a quote from Jeff:
" We’re going to be announcing something…but I won’t tell you what it is…we will be launching this year, not in the distant future. I’ll give you a much bigger hint: I’m going to be speaking at Walt Mossberg’s D Conference in May. It’s a high-end industry conference. Anyway, I’m going to be giving a talk there, and that would be something for the Palm fans to keep a close watch on."

The SleepStrip™ is a new screening device for sleep apnea, recently approved for marketing in the United States by the Food and Drug Administration.

The SleepStrip™ is a disposable tool for measuring respiration during sleep. It is a self-contained, microprocessor-driven system that contains four major elements:
  • Thermosensors for sensing airflow, one for each nostril and one for oral airflow
  • A built-in microprocessor to analyze the breathing patterns of the patient
  • A three-volt lithium battery to power the unit
  • A display to show the recorded results to the physician

These components are connected by electronic circuitry. There are two "wings" with adhesive to hold the SleepStrip™ to the upper lip, and a "bridge" containing the thermosensors.

The Dental Rat

I got to try the Dental Rat is Chicago. What is it?

The Dental R.A.T. (Remote Access Terminal) is a simple quiet hands-free solution to enter probe readings. It is a simple foot operated mouse with numbers for perio charting. It also allows hands-free access to intraoral cameras and digital x-rays!

Each of the four buttons can be used to record periodontal probe readings. If pushed once they are 1, 2, 3 or 4. If held down they are 5, 6, 7 or 8. The 4 and 8 button also acts as the right mouse click. The joystick moves the mouse cursor with speed and accuracy that are appropriate for a foot to control. The heel rests on the left mouse click and takes a firm downward motion to click or double click. It requires no special software, just plug into a USB port and go.

The device was invented by a hygienist and seems to work quite well. Ask your hygienist if she might like the idea.

As usual more information is available on their web site
