Training to Become a Scuba Diver? Start at the Dentist

Posted on December 23, 2016

Newswise — BUFFALO, N.Y. – Scuba divers may want to stop by their dentist’s office before taking their next plunge. A new pilot study found that 41% of divers experienced dental symptoms in the water, according to new research from the University at Buffalo (UB).

Due to the constant jaw clenching and fluctuations in the atmospheric pressure underwater, divers may experience symptoms that range from tooth, jaw, and gum pain to loosened crowns and broken dental fillings.

Recreational divers should consider consulting with their dentist before diving if they recently received dental care, says Vinisha Ranna, BDS, lead author and a student in the UB School of Dental Medicine.

“Divers are required to meet a standard of medical fitness before certification, but there are no dental health prerequisites,” says Ranna, who is also a certified stress and rescue scuba diver.

“Considering the air supply regulator is held in the mouth, any disorder in the oral cavity can potentially increase the diver’s risk of injury. A dentist can look and see if diving is affecting a patient’s oral health.”

The study, “Prevalence of dental problems in recreational SCUBA divers,” was published last month in the British Dental Journal.

The research was inspired by Ranna’s first experience with scuba diving in 2013. Although she enjoyed being in the water, she couldn’t help but notice a squeezing sensation in her teeth, a condition known as barodontalgia.

Published research on dental symptoms experienced while scuba diving is scarce or focuses largely on military divers, says Ranna, so she crafted her own study. She created an online survey that was distributed to 100 certified recreational divers. Those who were under 18 years old, ill, or taking decongestant medication were excluded.


Her goal was to identify the dental symptoms that divers experience and detect trends in how or when they occur.

Of the 41 participants who reported dental symptoms, 42% experienced barodontalgia, 24% described pain from holding the air regulator in their mouths too tightly and 22% reported jaw pain.

Another 5% noted that their crowns were loosened during their dive, and one person reported a broken dental filling.

“The potential for damage is high during scuba diving,” says Ranna, who has completed 60 dives.

“The dry air and awkward position of the jaw while clenching down on the regulator is an interesting mix. An unhealthy tooth underwater would be much more obvious than on the surface. One hundred feet underwater is the last place you want to be with a fractured tooth.”

The study also found that pain was most commonly reported in the molars and that dive instructors, who require the highest level of certification, experienced dental symptoms most frequently. This frequency is likely attributed to more time spent at shallower depths where the pressure fluctuations are the greatest, says Ranna.


The Professional Association of Diving Instructors has issued more than 24 million certifications around the world. As scuba diving gains popularity as a recreational sport, Ranna hopes to see oral health incorporated into the overall health assessments for certification.

Patients should ensure that dental decay and restorations are addressed before a dive, and mouthpiece design should be evaluated by manufacturers to prevent jaw discomfort, particularly when investigating symptoms of temporomandibular joint disorder in divers, says Ranna.

Additional investigators on the study include Hans Malmstrom, DDS, professor; Sangeeta Gajendra, DDS, associate professor; Changyong Feng, PhD, associate professor; and Michael Yunker, DDS, assistant professor, all of the University of Rochester School of Medicine and Dentistry.

Ranna is conducting a follow-up study with an expanded group of more than 1,000 participants.

She earned her bachelor of dental surgery from the Government Dental College and Hospital, Mumbai. Ranna is earning her DDS at the UB School of Dental Medicine through the International Dentist Program, a 2-year program for internationally trained dentists who seek to practice in the US.

PA Dental Office Under Investigation After Not Following Infection Control Procedures

Posted on December 22, 2016

Harrisburg, PA – The Pennsylvania Department of Health has advised patients of the Center for Family and Specialty Dentistry in Reading, Berks County, they might be at risk for infection after an investigation discovered the facility did not follow appropriate infection control procedures. The department recommends patients seen between December 19, 2015, and October 19, 2016, get tested for hepatitis B, hepatitis C, and human immunodeficiency virus (HIV).

“While we haven’t received reports of hepatitis B, hepatitis C, or HIV from patients, infection control procedures at this practice were inadequate and created the potential for harm, so we’re recommending patients get tested,” said Health Secretary Dr. Karen Murphy. “We prefer that patients receive information regarding their health directly from their provider. However, in this case, that did not happen, so we’ve contacted patients of this practice directly.”

The department recommends testing for current or former patients who had dental procedures performed at the office, such as cleanings, fillings, implants, denture fittings, and other procedures.

An investigation by the departments of Health and State found that the Center for Family and Specialty Dentistry practice did not follow appropriate procedures to properly clean, disinfect, or sterilize devices at their 2642 Bernville Road location in Reading, Berks County.

On October 21, the department sent a letter to the practice to cease and desist all patient care, as well as issued formal recommendations to improve patient safety. No patients should have received care at the practice and the practice remains closed until the infection control concerns are addressed.

“Infection control is an essential step in patient safety that cannot be overlooked,” said Secretary of State Pedro Cortés. “It’s important to talk to your dentist about infection control and what they are doing to protect you while under their care.”

On November 4, the Pennsylvania State Board of Dentistry temporarily suspended the dental licenses of Dr. Stephen Sulzbach, of Greenville, Mercer County, and Drs. Jana and Eric Osmolinski, of La Jolla, California, who practiced at the Center for Family and Specialty Dentistry, on the grounds that their continued practice may be an immediate and clear danger to the public health and safety. The temporary suspensions remain in effect pending further action by the board.

 

Researchers Examine Impact of NIH Research Funding to Dental Schools

Posted on December 21, 2016

Alexandria, Va., USA – Today, the International and American Associations for Dental Research (IADR/AADR) published three articles in the Journal of Dental Research that focus on the trends and impact of National Institutes of Health (NIH) research funding to dental schools and institutions.

A study titled "The NIH's Funding to US Dental Institutions from 2005 to 2014" by Chantelle Ferland, Morgan O'Hayre, Wendy Knosp, Jonathan Horsford, NIH, National Institute of Dental and Craniofacial Research (NIDCR), Bethesda, Md., USA; and Christopher Fox, IADR/AADR, Alexandria, Va., examines research funding from the NIH to dental institutions in the United States of America between 2005 and 2014 using publicly available data from the NIH Research Portfolio Online Reporting Tools (RePORT). Since research training and career development are also essential for the future of dental research, the authors of this study examined NIH's investment in both extramural research projects and training at dental institutions. Over the 10-year span, 56 US dental institutions received approximately $2.2 billion from more than 20 institutes, centers, and offices at the NIH. The NIDCR is the largest NIH supporter of dental institutions, having invested 70% of the NIH total, about $1.5 billion. The NIDCR is also the primary supporter of research training and career development, as it has invested $177 million, which represents 92% of the total NIH investment of $192 million. The goal of this study was to provide data on NIH and NIDCR support for US dental institutions that could inform future decision making related to oral health research and dental professional training.

"Recent Trends in Oral Cavity Cancer Research Support in the United States" by Andrew Fribley, Peter Svider, Naweed S. Raza and Danielle Garshott, Wayne State University, Detroit, Mich., USA; Blake Warner, University of Pittsburgh, Pa., USA; and Keith Kirkwood, Medical University of South Carolina, Charleston, USA, used a different approach to characterize oral cavity cancer funding from NIH, with a secondary aim of comparison to NIH support for research on other malignancies. This study found that overall funding for oral cavity cancer research decreased considerably after 2009. Funding administered through the NIDCR was 6.5-times greater than dollars awarded by the NIH National Cancer Institute (NCI) in 2000; over the time period evaluated, NIDCR support decreased in most years while NCI support increased and approached NIDCR funding levels. There has been increased volatility in funding support in recent years possibly due to budget cuts and sequestration. The NCI has played an increasingly important role in supporting oral cavity cancer research, concomitant with decreasing NIDCR support. This study's findings suggest that oral cavity cancer research is underfunded relative to other non-oral cavity malignancies, indicating a need to increase the focus on rectifying the gap.

A perspective piece titled "Impact of Funding by NIDCR for Research to Dental Schools" by Peter Polverini, University of Michigan, Ann Arbor, USA, and Mark Lingen, University of Chicago, Ill., USA, highlights that we are at a tipping point in oral health sciences, dental education and dental practice, and that dental education must continue to search for a new direction in a health care environment that is uncertain and unpredictable.

"It's important for the community to understand that research remains a cornerstone for dentistry and advocating for increased funding for NIH/NIDCR remains a top priority for AADR," said AADR President Jack Ferracane. "Increased investments in dental, oral and craniofacial research and other oral health programs benefit the health of the public. AADR will continue to communicate to Congress the importance of biomedical research for the health of the population."

A companion podcast is also available, featuring interviews with AADR President Jack Ferracane, IADR/AADR Executive Director Christopher Fox and NIDCR Director Martha Somerman.

New CDC Data Show Continuing Opioid Epidemic

Posted on December 20, 2016

Drug overdose deaths, including opioid overdose deaths, continue to increase in the United States, according to new data published today in CDC’s Morbidity and Mortality Weekly Report.

In 2015 more than 52,000 people died from a drug overdose; of those, 33,091 (63.1%) involved a prescription or illicit opioid. Since 2000, more than 300,000 Americans have lost their lives to an opioid overdose.

“Too many Americans are feeling the devastation of the opioid crisis either from misuse of prescription opioids or use of illicit opioids,” said CDC Director Tom Frieden, MD, MPH. “Urgent action is needed to help health care providers treat pain safely and treat opioid use disorder effectively, support law enforcement strategies to reduce the availability of illicit opiates, and support states to develop and implement programs that can save lives.”

CDC’s latest national analyses indicate that the increase in opioid overdose death rates is driven in large part by illicit opioids, like heroin and illicitly manufactured fentanyl, a synthetic opioid. The new data show from 2014 to 2015:

-Death rates for synthetic opioids other than methadone (including drugs such as tramadol and fentanyl, referred to as synthetic opioids) increased 72.2%

-Heroin death rates increased 20.6%

-Synthetic opioid and heroin death rates increased across all age groups 15 and older, in both sexes, and among all races/ethnicities.

-Methadone death rates declined 9.1%

-Natural opioids (including morphine and codeine) and semi-synthetic opioids (including commonly prescribed pain medications such as oxycodone and hydrocodone) were involved in more than 12,700 deaths in 2015; death rates increased 2.6% from 2014 to 2015 in this category. However, the increase has slowed compared with the increase from 2013 to 2014.

State analyses of drug overdoses deaths

During 2010 to 2015, the rate of drug overdose deaths in the United States increased in 30 states and DC, remained stable in 19 states, and showed decreasing trends followed by increases in two states. This new report includes state analyses of death certificate data for opioid overdoses in 28 states with consistent and high quality reporting of specific drugs involved in an overdose. Data for the 28 states show:

-16 states had increases in synthetic opioid death rates from 2014 to 2015. The greatest percent increases in death rates were in New York (135.7%), Connecticut (125.9%) and Illinois (120%). Alternatively, when assessing potential burden by absolute rate changes (reflecting the number of deaths and lives affected in each state, per every 100,000 people), Massachusetts, New Hampshire, Ohio, Rhode Island, and West Virginia had the largest rate increases of synthetic opioid deaths from 2014 to 2015.

-11 states had increases in heroin death rates, with the greatest percent increases in death rates in South Carolina (57.1%), North Carolina (46.4%), and Tennessee (43.5%). Alternatively, when assessing potential burden by absolute rate changes (reflecting the number of deaths and lives affected in each state, per every 100,000 people) Connecticut, Massachusetts, Ohio, and West Virginia had the largest rate increases of heroin deaths from 2014 to 2015.

-New Mexico, Oklahoma, Virginia had decreases in rates of death involving natural/semi-synthetic opioids.

Today’s report shows significant increases across states in death rates from heroin and synthetic opioid deaths, coupled with continuing high numbers of fatal overdoses related to natural/semi-synthetic opioid deaths further illustrate the continued problem with misuse of prescription opioids and the substantial impact of illicit opioids on this epidemic. 

“The need to address the full spectrum of substance misuse as a health issue is ever-present,” said Nora D. Volkow, MD, director of the National Institute on Drug Abuse. “Science-based solutions to reduce illicit opioid use and improve both health and life outcomes for opioid use disorder need to be implemented so we can start breaking down the barriers preventing effective treatment from reaching the millions of Americans who could benefit.”

Need for coordinated public health and public safety response

Today’s report highlights the continued need for public health and law enforcement to work together to prevent overdose deaths, including these actions:

  • Improve opioid prescribing to reduce unnecessary exposure to opioids and prevent addiction by training providers and implementing the CDC Guideline for Prescribing Opioids for Chronic Pain.

  • Improve access to and use of prescription drug monitoring programs.

  • Protect people experiencing opioid use disorder (OUD) by expanding OUD treatment capacity and naloxone distribution.

  • Implement harm reduction approaches including naloxone distribution and syringe services.

  • Support law enforcement strategies to reduce and to improve detection of the illicit opioid supply by working with state and local public health agencies.

CDC’s Overdose Prevention in States initiatives include funding for state-level public health efforts in 44 states and Washington, D.C., to implement key surveillance and prevention activities addressing both prescription and illicit opioids. CDC works with states, communities, and prescribers to prevent opioid misuse and overdose by tracking and monitoring the epidemic; helping states scale up effective programs; and equipping health care providers with tools and guidance needed to make informed clinical decisions. In March 2016, CDC released the Guideline for Prescribing Opioids for Chronic Pain to provide recommendations for the prescribing of opioid pain medication for patients 18 and older in primary care settings. Learn more at www.cdc.gov/drugoverdose.

“The increase in overdose deaths is tangible evidence of the real impact of substance use disorder on millions of Americans and underscores the importance of the Administration's continued focus on prevention, treatment and recovery services." said Kathryn E. Martin, acting Assistant Secretary for Planning and Evaluation at HHS.  "The President recently signed legislation to implement his plan to invest $1 billion in helping communities combat this epidemic.  And the Affordable Care Act expands mental and substance use disorder benefits and protections for more than 60 million Americans. These steps are essential to helping to turn the tide of this epidemic."

The Obama Administration has undertaken a series of initiatives to address the opioid crisis. On December 13, 2016, the President signed the 21st Century Cures Act, which implements his Budget proposal to provide $1 billion in new funding to combat the opioid crisis. In addition, HHS has made addressing the opioid overdose epidemic a high priority, implementing an evidence-based initiative in 2015, focused on three priority areas: informing opioid prescribing practices, increasing the use of naloxone, and expanding Medication-Assisted Treatment.  HHS continues to coordinate with agencies across the Department to ensure effective implementation of the initiative’s programs and policies, improve prescribing practices, reduce overdose deaths, and support the millions of Americans in recovery.

New Stem-Cell Delivery Approach Regenerates Dental Pulp-like Tissue

Posted on December 20, 2016

BOSTON (Dec. 19, 2016)—When a tooth is damaged, either by severe decay or trauma, the living tissues that comprise the sensitive inner dental pulp become exposed and vulnerable to harmful bacteria. Once infection takes hold, few treatment options—primarily root canals or tooth extraction—are available to alleviate the painful symptoms.

Researchers at Tufts University School of Dental Medicine (TUSDM) now show that using a collagen-based biomaterial to deliver stem cells inside damaged teeth can regenerate dental pulp-like tissues in animal model experiments. The study, published online in the Journal of Dental Research on Dec. 15, supports the potential of this approach as part of a strategy for restoring natural tooth functionality.

"Endodontic treatment, such as a root canal, essentially kills a once living tooth. It dries out over time, becomes brittle and can crack, and eventually might have to be replaced with a prosthesis,” said senior study author Pamela Yelick, PhD, professor at TUSDM and director of its Division of Craniofacial and Molecular Genetics. “Our findings validate the potential of an alternative approach to endodontic treatment, with the goal of regenerating a damaged tooth so that it remains living and functions like any other normal tooth.”

Yelick and her colleagues, including lead study author Arwa Khayat, former graduate student in dental research at TUSDM, examined the safety and efficacy of gelatin methacrylate (GelMA)—a low-cost hydrogel derived from naturally occurring collagen—as a scaffold to support the growth of new dental pulp tissue. Using GelMA, the team encapsulated a mix of human dental pulp stem cells—obtained from extracted wisdom teeth—and endothelial cells, which accelerate cell growth. This mix was delivered into isolated, previously damaged human tooth roots, which were extracted from patients as part of unrelated clinical treatment and sterilized of remaining living tissue. The roots were then implanted and allowed to grow in a rodent animal model for up to eight weeks.

The researchers observed pulp-like tissue inside the once empty tooth roots after two weeks. Increased cell growth and the formation of blood vessels occurred after four weeks. At the 8-week mark, pulp-like tissue filled the entire dental pulp space, complete with highly organized blood vessels populated with red blood cells. The team also observed the formation of cellular extensions and strong adhesion into dentin—the hard, bony tissue that forms the bulk of a tooth. The team saw no inflammation at the site of implantation, and found no inflammatory cells inside implanted tooth roots, which verified the biocompatibility of GelMA.

Control experiments, which involved empty tooth roots or tooth roots with only GelMA and no encapsulated cells, showed significantly less growth, unorganized blood vessel formation, and poor or nonexistent dentin attachment.

The results support GelMA-encapsulated human dental stem cells and umbilical vein endothelial cells as part of a promising strategy to restore normal tooth function, according to the study authors. However, they note that the current study was limited to partial tooth roots and did not examine nerve formation in regenerated dental pulp tissue. They emphasize the need for additional safety and efficacy studies in larger animal models before human clinical trials can be considered.

“A significant amount of work remains to be done, but if we can extend and validate our findings in additional experimental models, this approach could become a clinically relevant therapy in the future,” said Yelick, who is also a member of the Cell, Molecular & Developmental Biology; Genetics; and Pharmacology & Experimental Therapeutics programs at the Sackler School of Graduate Biomedical Sciences at Tufts. “Our work is early stage, but we are excited for the possibility of someday giving patients the option of regenerating their own teeth.”
