Dental X-rays can predict fractures

07.12.2011
It is now possible to use dental X-rays to predict who is at risk of fractures, reveals a new study from researchers at the Sahlgrenska Academy reported in the journal Nature Reviews Endocrinology.

In a previous study, researchers from the University of Gothenburg’s Sahlgrenska Academy and Region Västra Götaland demonstrated that a sparse bone structure in the trabecular bone in the lower jaw is linked to a greater chance of having previously had fractures in other parts of the body.

X-rays investigates bone structure

The Gothenburg researchers have now taken this a step further with a new study that shows that it is possible to use dental X-rays to investigate the bone structure in the lower jaw, and so predict who is at greater risk of fractures in the future. Published in the journal Bone, the results were also mentioned in both Nature Reviews Endocrinology and the Wall Street Journal.

Linked to risk of fractures

"We’ve seen that sparse bone structure in the lower jaw in mid-life is directly linked to the risk of fractures in other parts of the body, later in life,”says Lauren Lissner, a researcher at the Institute of Medicine at the Sahlgrenska Academy.

Study started 1968

The study draws on data from the Prospective Population Study of Women in Gothenburg started in 1968. Given that this has now been running for over 40 years, the material is globally unique. The study included 731 women, who have been examined on several occasions since 1968, when they were 38-60 years old. X-ray images of their jaw bone were analysed in 1968 and 1980 and the results related to the incidence of subsequent fractures.

For the first 12 years fractures were self-reported during followup examinations. It is only since the 1980s that it has been possible to use medical registers to identify fractures. A total of 222 fractures were identified during the whole observation period.

One out of five in higher risk

The study shows that the bone structure of the jaw was sparse in around 20% of the women aged 38-54 when the first examination was carried out, and that these women were at significantly greater risk of fractures.

The study also shows that the older the person, the stronger the link between sparse bone structure in the jaw and fractures in other parts of the body.

Applies for both sexes

Although the study was carried out on women, the researchers believe that the link also applies for men.

“Dental X-rays contain lots of information on bone structure,” says Grethe Jonasson, the researcher at the Research Centre of the Public Dental Service in Västra Götaland who initiated the fractures study. “By analysing these images, dentists can identify people who are at greater risk of fractures long before the first fracture occurs.”

The article “A prospective study of mandibular trabecular bone to predict fracture incidence in women: A low-cost screening tool in the dental clinic” was published in Bone in October.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
