Infection outbreaks on teeth can cause “alopecia areata” or localized hair loss

27.11.2007
There is a close relationship between infection outbreaks on teeth and the presence of alopecia areata or localized alopecia, a type of hair loss which has an unknown origin.

Alopecia areata starts with bald patches on the scalp, and sometimes elsewhere on the body. The disease occurs in males and females of all ages, and experts believe that it affects 1 out 1000 people.

Research by professors José Antonio Gil Montoya and Antonio Cutando Soriano, at the Department of Stomatology of the University of Granada, advises going to the dentist when patients notice localized hair loss, in order to receive a careful examination of their oral health.

“Alopecia areata is a dermatitis which presents the following signs: The typical pattern is for one or more round bald patches to appear on the scalp, in the beard, or in the eyebrows, or to undergo a loss of eyelashes. Alopecia areata is thought to be an auto-immune disease”, stated the researchers. Hair re-grows in most patients after several months. However, in a quarter of all patients the condition recurs once or more. According to professors at the UGR, the affected hair follicles are not totally destroyed. Therefore, hair can grow back, although patients who have already suffered from alopecia areata may have recurrences.

Unpredictable development
Frequently, patients with alopecia areata have hairs with the shape of an exclamation mark on the border of the bald patch. Hairs become weak and fall out easily. Several studies suggest that alopecia areata has unpredictable development: sometimes hair grows back within a few weeks, but in some cases the disease progresses and can cause further hair loss on scalp and body.

Until the research at the UGR, which establishes for the first time a relationship between alopecia areata and dental disease, the origin of this kind of hair loss was not well known. Hair-follicle tissue inflames without cicatrisation. In alopecia areata, the affected hair follicles are mistakenly attacked by the immune system. Some of the factors that cause alopecia are: genetics, family history of alopecia, non-specific immune reactions, specific auto-immune reactions of certain organs and emotional stress.

“We have found that bald patches caused by tooth infection are not always in the same place. They normally appear on a line projected from the dental infection and can thus can be located on the face at the level of the maxillary teeth, above a line through the lip-angle to the scalp, beard, or even to the eyebrow. Nevertheless, they can also be located far from infection outbreak.” Explained Gil Montoya and Cutando Soriano.

Im Focus: First diode for magnetic fields

Innsbruck quantum physicists have constructed a diode for magnetic fields and then tested it in the laboratory. The device, developed by the research groups led by the theorist Oriol Romero-Isart and the experimental physicist Gerhard Kirchmair, could open up a number of new applications.

Electric diodes are essential electronic components that conduct electricity in one direction but prevent conduction in the opposite one. They are found at the...

Im Focus: UNH scientists help provide first-ever views of elusive energy explosion

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...

Im Focus: A Chip with Blood Vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

Im Focus: A Leap Into Quantum Technology

Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
