The five-year survival rate for U.S. patients with cancer of the base of the tongue or tonsils doubled between 1980 and 2002, according to a new study in Cancer Causes & Control (January 2012, Vol. 23:1, pp. 153-164). In addition, patients with human papillomavirus (HPV)-related cancers had greater survival rates than those with other oral cancers, and survival was greater for male patients than females regardless of age, according to
The combination of functional resection laser surgery and intensity-modulated radiotherapy (IMRT) treatment is more effective at extending the lives of patients with advanced head and neck cancers than having only radiotherapy treatment, according to a study presented at the recent Radiological Society of North America (RSNA) 2011 conference in Chicago. Both therapies have been well established as sole treatments for head and neck cancers. To determine if both treatments combined
Arch Biophysics scientists have inhibited biofilm formation on titanium using the company’s proprietary peptide technology. The attachment of Pseudomonas aeruginosa was reduced by more than 50% on titanium coated with Arch lead compounds ABP-0904 and ABP-0918, according to the company. These data are similar to previously disclosed results in which ABP-0904 and ABP-0918 were effective in inhibiting attachment of several bacteria, including Staphylococcus aureus, Streptococcus viridans, P. aeruginosa, and Listeria

Researchers from Yale University have uncovered the molecular “tricks” used by bacteria to fight the effects of fluoride (Science, December 22, 2011). The researchers found that sections of RNA messages called riboswitches — which control the expression of genes — detect the buildup of fluoride and activate the defenses of bacteria, including those that contribute to tooth decay. “These riboswitches are detectors made specifically to see fluoride,” stated senior study

Er:YAG laser irradiation can effectively debond porcelain veneers while preserving tooth structure, according to a study in Lasers in Surgery and Medicine (December 2011, Vol. 43:10, pp. 965-974). Using Er:YAG lasers to remove porcelain veneers has not been previously described in the scientific literature, according to the study authors, from the University of California, San Francisco School of Dentistry. They used Fourier transform infrared (FTIR) spectroscopy on 10 flat veneer

Times are tough for recent dental school graduates. They can easily accrue a personal debt for school loans in excess of $150,000 to $250,000 before even a single dollar is earned in clinical practice. In recent years, interstate Medicaid clinics have come onto the scene. Their focus is primarily the niche market of underserved Medicaid-eligible children. They would argue that they fill the need of a demographic that receives little

CEL-SCI is expanding its phase III trial of the investigational therapy Multikine to four additional European countries: Spain, the Czech Republic, Slovakia, and Croatia. These countries were selected because they have a high incidence of head and neck cancer, as well as the required facilities and scientific and technical personnel with the necessary experience for running the phase III study, the company said. The Multikine study is currently being run
