Can mouthwash protect irradiated enamel and dentin?

Can chlorhexidine and fluoride mouthwashes mitigate the effect of gamma irradiation therapy damage to enamel and dentin? A new study that looked at the effectiveness of mouthwash protocols in preventing gamma irradiation therapy damage to the ultimate tensile strength (UTS) of enamel and dentin yielded mixed results (Journal of Dental Research, May 2011, Vol. 90:5, pp. 659-664). The researchers — from two Brazilian universities — divided 120 teeth into two

Researchers discover how tooth decay enzyme functions

Researchers from the U.K. and Japan used the Diamond Light Source synchrotron in Oxfordshire and the Photon Factory synchotron in Tsukuba, Japan, to solve the 3D structure of an enzyme that plays a key role in tooth decay caused by sugar (Journal of Molecular Biology, April 29, 2011, Vol. 408:2, pp. 177-186). Noting that glucansucrase (GSase) from Streptococcus mutans is an essential agent in dental caries pathogenesis, the researchers examined

Unfortunately, more often it’s a trusted, longtime employee who has an insider’s knowledge of your bookkeeping practices and access to your bank account.

But experts say it is often just a matter

Combined CT, FDG-PET improves head/neck cancer treatments

Combining CT with fluorodeoxyglucose positron emission tomography (FDG-PET) imaging results in significantly more defined tumor outlines and potentially different treatment options in head and neck cancer patients compared with using CT alone, according to research presented April 29 at the Cancer Imaging and Radiation Therapy Symposium in Atlanta. In this trial, conducted at Utrecht University Medical Center, 327 patients were treated with intensity-modulated radiation therapy for head and neck cancer.
