Postmenopause and periodontal disease

22.07.2005


Postmenopausal women may significantly reduce tooth loss by controlling their periodontal disease, according to a study in the Journal of Periodontology.



Researchers from the University at Buffalo, School of Dental Medicine did a follow-up evaluation on 106 postmenopausal women and found that during an average of 11.7 years follow-up, 57.5 percent of the participants lost at least one tooth.

"We found that alveolar bone loss (the bone that holds the tooth in the mouth) is the strongest independent predictor of tooth loss in the postmenopausal population," explained Mine Tezal, DDS and study author. "Each millimeter of alveolar bone loss increased the risk of tooth loss 3 times, and the risk of tooth loss increased 2.5 times for each millimeter of clinical attachment loss, or soft tissue attachment between the tooth and alveolar bone." (This is also known as loss of gums and bone.)


The health of teeth depends upon the integrity of the alveolar bone holding them in the mouth. Periodontal disease is the major cause of alveolar bone loss and tooth loss in patients over 35.

"The long follow-up period is an advantage of this study since researchers were able to evaluate the same people more than 10 years later," said Vincent J. Iacono, DMD and president of the American Academy of Periodontology. "Since alveolar bone loss has been shown to be a significant factor for tooth loss in postmenopausal women, studies will be needed to determine possible aggravating effects of post menopause on the severity of periodontal disease. Until we know more, postmenopausal women will want to control periodontal disease to significantly reduce their risk of alveolar bone loss and tooth loss."

Estrogen deficiency after menopause and consequent loss of bone mineral density have been shown to be associated with increased rate of tooth loss. These relationships may be explained by increased severity of periodontal disease in estrogen deficiency.

The participants of this study had participated in a past study in 1989 and 1991. The average follow-up time was 11.7 years. The age ranged from 45 to 73 and all subjects had reached menopause with the average age at 48.8 years.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
