In a study, researchers at the University of São Paulo's Ribeirão Preto School of Medicine (FMRP-USP), in Brazil, finds that the more frequent the migraine attacks, the more severe will be the so-called temporomandibular disorder, or TMD. The temporomandibular joint acts like a sliding hinge connecting the jawbone to the skull, therefore the disorder's symptoms includes difficulty chewing and joint tension.
"Our study shows that patients with chronic migraine, meaning attacks occurring on more than 15 days per month, are three times as likely to report more severe symptoms of TMD than patients with episodic migraine," said Lidiane Florencio, the first author of the study, which is part of the Thematic Project "Association study of clinical, functional and neuroimaging in women with migraine", supported by the São Paulo Research Foundation - FAPESP.
Previous studies already indicated that migraine is somehow associated with pain in the chewing muscles. However, this research was the first to consider the frequency of migraine attacks when analyzing its connection with TMD: eighty-four women in their early to mid-thirties were assessed, being that 21 were chronic migraine patients, 32 had episodic migraine, while 32 with no history of migraine were included as controls - the results were published in the Journal of Manipulative and Physiological Therapeutics.
Signs and symptoms of TMD were observed in 54% of the control participants without migraine, 80% of participants with episodic migraine, and 100% of those with chronic migraine.
For Florencio, central sensitization may explain the association between the frequency of migraine attacks and the severity of TMD.
"The repetition of migraine attacks may increase sensitivity to pain," she said. "Our hypothesis is that migraine acts as a factor that predisposes patients to TMD. On the other hand, TMD can be considered a potential perpetuating factor for migraine because it acts as a constant nociceptive input that contributes to maintaining central sensitization and abnormal pain processes." Nociceptive pain is caused by a painful stimulus on special nerve endings called nociceptors.
Migraine and TMD have very similar pathological mechanisms. Migraine affects 15% of the general population, and progression to the chronic form is expected in about 2.5% of migraine sufferers. On the other hand TMD is stress-related as much as it has to do with muscle overload. Patients display joint symptoms - such as joint pain, reduced jaw movement, clicking or popping of the temporomandibular joint - but also develop a muscular condition, including muscle pain and fatigue, and/or radiating face and neck pain.
Which came first?
TMD and migraine are comorbidities. However, while people who suffer from migraine are predisposed to have TMD, people with TMD will not necessarily have migraine.
"Migraine patients are more likely to have signs and symptoms of TMD, but the reverse is not true. There are cases of patients with severe TMD who don't present with migraine," said Débora Grossi, the lead researcher for the study and principal investigator for the Thematic Project.
The researchers believe that TMD may increase the frequency and severity of migraine attacks, even though it does not directly cause migraine.
"We do know migraine isn't caused by TMD," Florencio said. "Migraine is a neurological disease with multifactorial causes, whereas TMD, like cervicalgia - neck pain - and other musculoskeletal disorders, is a series of factors that intensify the sensitivity of migraine sufferers. Having TMD may worsen one's migraine attacks in terms of both severity and frequency."
The journal article concludes that an examination of TMD signs and symptoms should be clinically conducted in patients with migraine.
"Our findings show the association with TMD exists but is less frequent in patients with rare or episodic migraine," Grossi said. "This information alone should change the way clinicians examine patients with migraine. If migraine sufferers tend to have more severe TMD, then health professionals should assess such patients specifically in terms of possible signs and symptoms of TMD."

Alexandria, Va., USA – The International and American Associations for Dental Research (IADR/AADR) have published a special issue in the Journal of Dental Research (JDR) on orofacial clefting and dental and craniofacial anomalies. Dr. Brian Schutte, Michigan State University, East Lansing, USA, served as the guest editor of this special issue along with JDR Associate Editor, Dr. Joy Richman, University of British Columbia, Canada.
The disease burden of orofacial structural defects such as cleft lip with or without cleft palate (CL/P) and tooth agenesis is very high. With one of out every 700 individuals affected, nonsyndromic orofacial clefts are some of the most common birth defects.
From infancy to adulthood, the correction of clefts involves a series of invasive surgeries and dental rehabilitation. Dental abnormalities such as tooth agenesis require medical care in childhood and expensive prosthetic treatment. This special issue contains articles and reviews on recent scientific and technical advances in craniofacial development and genetics.
Topics in this special issue range from tooth number and root formation, human and animal genetic studies on orofacial clefting, reviews that prioritize the variants most likely to cause disease, the pathways required for palatogenesis, experimental articles on the periderm and drug therapy articles that rescue cleft palate in mutant mice.
"I am honored that I was able to serve as a co-guest editor of this JDR special issue on orofacial clefting," said Joy Richman. "We have curated an excellent group of articles covering the recent scientific and technical advances in craniofacial development and genetics. The discoveries reported in this series of articles could lead to improvements in the better diagnosis and ultimately treatment of challenging craniofacial and dental anomalies."
This special issue is accompanied by an Editorial "Face Forward: Gene Variants, Pathways, and Therapies for Craniofacial Anomalies" and a companion podcast moderated by Editor-in-Chief, William Giannobile.

A research team at New York University College of Dentistry (NYU Dentistry) has been approved for a $13.3 million funding award by the Patient-Centered Outcomes Research Institute (PCORI) to study cavity prevention, quality of life, and school performance.
NYU Dentistry's Richard Niederman, DMD, and Ryan Richard Ruff, MPH, PhD, will lead the five-year study comparing the effectiveness of two cavity-prevention techniques — a “simple” treatment of topical silver and fluoride, and a “complex” treatment of traditional sealants and fluoride. The study will be conducted in elementary schools in the Bronx, an area with a scarcity of dental care providers and clinics.
More than half of U.S. elementary school-age children have had a dental cavity, and more than 20 percent have untreated cavities. The prevalence of cavities in the Bronx – the poorest borough in New York City and home to a large Hispanic/Latino population – is almost twice the national average.
Children with dental cavities and associated toothaches face multiple disadvantages, including reduced quality of life, school absences, difficulty paying attention in school, and lower standardized test scores. Unfortunately, traditional office-based dental care presents multiple barriers to treatment, including cost, fear of dentists, and geographic isolation. Bringing care to children instead of children to care eliminates these barriers.
Through prior work in New York, Massachusetts, New Hampshire, Maine, and Colorado, NYU Dentistry researchers determined that “complex” school-based cavity prevention programs are effective in reducing cavities by two-thirds. Preliminary results suggest that “simple” prevention can be equally effective. Discussions and surveys of patients and other partners revealed that school-based care was overwhelmingly preferred over office-based care and that “simple” care was preferred over “complex” care.
In the PCORI-funded study, the researchers will compare cavity prevention programs in 60 high-need elementary schools in the Bronx that serve low-income, Hispanic/Latino families. Schools will be selected at random to receive either the “simple” treatment of silver diamine fluoride and fluoride varnish, or the “complex” treatment of sealants and fluoride varnish. All children will receive the same preventive dental care twice each year. The researchers will assess untreated cavities, quality of life, and student achievement to compare the outcomes of both treatments.
A unique aspect of the study is its collaboration with the NYU Rory Meyers College of Nursing to deliver care, along with NYU dental hygienists. Since there are 3 million nurses in the U.S., versus 250,000 dental hygienists, the research team will also compare care delivered by nurses and by dental hygienists. The participation of nurses will build upon NYU Meyers’ efforts to expand oral health nursing education and practice and to strengthen existing oral health and nursing initiatives.
“The overall goal of our proposed research is to improve oral health equity by determining the most effective, patient-centered, and efficient school-based cavity prevention methods,” said Dr. Niederman, professor and chair of the Department Epidemiology & Health Promotion at NYU Dentistry. “Our expectation is that both will be similarly effective in reducing untreated cavities by two thirds. However, for the same time and cost, hygienists or nurses can treat four times more children with the simpler prevention.”
The study was selected for funding through PCORI’s Pragmatic Clinical Studies Initiative, an effort to produce results that are broadly applicable to a diverse range of patients and care situations and can be more quickly taken up in routine clinical practice.
“This is an unparalleled opportunity to explore the long-term impact of oral health on quality of life and student achievement,” said Dr. Ruff, assistant professor of epidemiology & health promotion at NYU Dentistry. “This research has the potential to improve multiple outcomes relevant to children and their families.”
Many clinical studies test whether a treatment works under ideal conditions in specialized research centers, but health care is rarely delivered in such idealized situations and settings. Pragmatic clinical studies test a treatment’s effectiveness in “real-life” practice situations, such as typical hospitals, clinics, and schools, and can include a wider range of study participants, making their findings more generally applicable.
“This project was selected for PCORI funding not only for its scientific merit and commitment to engaging patients and other healthcare stakeholders in a major study conducted in real-world settings, but also for its potential to answer an important question about oral health and fill a crucial evidence gap,” said PCORI Executive Director Joe Selby, MD, MPH. “We look forward to following the study’s progress and working with NYU College of Dentistry to share its results.
The NYU Dentistry study was selected through a highly competitive review process in which patients, caregivers, and other stakeholders joined scientists to evaluate the proposals.
The award to Drs. Niederman and Ruff has been approved pending completion of a business and programmatic review by PCORI staff and issuance of a formal award contract.
PCORI is an independent, nonprofit organization authorized by Congress in 2010. Its mission is to fund research that will provide patients, their caregivers, and clinicians with the evidence-based information needed to make better-informed healthcare decisions.

Current Trends in Endodontic Disinfection
Rebekah Lucier Pryles, DMD
Clinicians must rely on other treatment methods to sufficiently disinfect the root canal system. Irrigants, including sodium hypochlorite and chlorhexidine gluconate, both flush the root canal system of debris and possess antimicrobial capabilities. Furthermore, adjunctive irrigation techniques, including passive ultrasonic irrigation, eliminate many intracanal bacteria effectively.
The Ongoing Challenge of Waterborne Infections
John A. Molinari, PhD
Infection caused by waterborne organisms from contaminated water sources and the subsequent burden of disease is not merely a problem for developing countries; it also poses a significant threat in countries with established water treatment procedures and infrastructures.
The Cost of Infection Control Noncompliance
Louis G. DePaola, DDS, MS
Although most dentists follow infection-control protocols carefully, a very small percentage either does not or has momentary lapses. The costs of not following guidelines and recommendations can be high, leading to substantial loss of income, causing long-lasting damage to a provider’s professional reputation, and having a long-term impact on the health and well being of patients.
