"If we find the patients in time, their risk of developing chronic pain as adults declines," says dentist Ing-Marie Nilsson, who recently defended her doctoral dissertation at the Faculty of Dentistry at Malmö University College in Sweden.
Her dissertation, Reliability, validity, incidence and impact of termoromandibular pain disorders in adolescents, shows that more than four percent of all children between the ages of 12 and 19 examined by the National Dental Service in Östergötland County suffer from TMD pain.
In the study, which started in 2000, some 1,200 teens reported that they have pain. The figures are based on the responses given by the adolescents to two questions: "Do you have pain in the temple, face, jaw, or jaw joint at least once a week?" and "Do you experience pain at least once a week when you open your mouth or chew?" If the adolescents answered yes to one or both questions, they were registered as patients with TMD pain.
Ing-Marie Nilsson is not surprised by the outcome of the study, since earlier studies have presented similar results.
"But we are unique in having examined so many patients," she says. She feels the problem is underestimated.
"For those suffering from it, it is definitely a problem, and more people should be able to get help than actually do."
Her dissertation shows that in 2000 only half of those who wanted help for their pain were actually offered help.
One of the four studies that make up the dissertation shows that girls are afflicted more often than boys and that the problem increases with age. In other ways as well, TMD evinces a picture like that of other painful conditions, such as headache. It is unusual in children and usually debuts at puberty.
"This is a difficult age, especially for girls."
One study shows that 60 percent of those treated with an acrylic splint experience at least a 50-percent reduction in pain. But Ing-Marie Nilsson believes that in many cases it would be enough simply to provide adequate information or behavior-oriented treatment, where the patient learns various relaxation techniques.
The earlier these patients are discovered, the lower the risk of their developing chronic pain as adults.
Ing-Marie Nilsson's dissertation shows that the majority will be fine without major treatment measures, but for a small group, the pain becomes both recurrent and protracted.
This smaller group needs help if they are to avoid a long period of disability.
"It is important to teach them ways to deal with the pain early in life," says Ing-Marie Nilsson.

The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
