New fingerprint visualization method uses X-rays to reveal missing clues
Dusting for fingerprints can sometimes alter the prints, erasing valuable forensic clues. Now, chemists say they have developed a new fingerprint visualization technique using X-rays that leaves prints intact and, in addition, reveals chemical markers that could give investigators new clues for tracking criminals and missing persons.  more

Dental practitioners can be instrumental in preventing their patients' eating disorders
Dental practitioners play a crucial role in the early identification, referral, and case management of their patients with eating disorders, yet little has been reported regarding current secondary prevention practices. Dental professionals are often the first health care providers to identify manifestations of disordered-eating behavior.  more

'Speaker's cramp', a new type of involuntary mouth-, lip-muscle movement
Fifteen percent of all teenagers in the United States undergo orthodontic treatment. Craniofacial Risk Index (CRI) scores, calculated from the radiographs routinely obtained on all orthodontic patients, correctly classified 80% of apneic and 78% of non-apneic adult snorers into high- and low-Respiratory Disturbance Index (RDI) groups. (Sleep apnea is a temporary suspension of breathing during sleep, with potentially serious consequences.) Researchers at Case Western Reserve University (Cleveland, OH) wondered whether similar radiographic use could identify adolescent orthodontic patients with high RDI scores.  more


Scientists suggest a role for estrogen receptor in behavioral sex differences
What makes a man behave like a man and a woman a woman?  The answer may be partly in your genes. Researchers at the University of Virginia Health System have discovered a new twist on the role that estrogens play in the development of behavioral differences between males and females.  more

Discovery may lead to better Candidiasis drug
Oral biologists at the University at Buffalo have shown for the first time how histatin, the naturally occurring antifungal agent in saliva, kills the oral pathogen Candida albicans, the fungus responsible for most HIV-related oral infections.  more

Cornea transplants can be improved
Improving the training and standardizing the procedures used by the nation's eye banks to assess corneal cells may help to select corneas with optimal health for transplantation, according to new study led by Jonathan H. Lass, MD, principal investigator of the study and chairman of the Department of Ophthalmology at University Hospitals of Cleveland and Case Western Reserve University School of Medicine.  more

Routine dental panoramic X-rays not necessary, study shows
Most dental patients would agree that the fewer dental X-rays they are exposed to, the better. Now, a new study by dental researchers at the University at Buffalo has shown that one type of X-ray patients receive routinely, called the panoramic X-ray, could be used selectively in some cases instead of as a routine diagnostic tool.  more
