...present, many universities grant licenses to private companies to use their discoveries in exchange for royalty payments. Over the years, the Procter & Gamble Co., makers of Crest toothpaste, paid Indiana University more than $2 million because Indiana held a patent on stannous fluoride. The novel element in Bok's proposal was the idea that universities could make more money by cutting out the middleman and sharing directly in the equity of their own product-development companies. As costs rise throughout higher education, commercial temptations will grow, and the search for ways to turn campus research into cam pus revenue...
Developed at Indiana University by Dr. Joseph C. Muhler and Dr. George Stookey, the prophylactic paste embodies more than 20 times the fluoride concentration of toothpastes now on drug-store shelves. The sweet-tasting paste polishes teeth as well. Dr. Muhler, who developed Crest, the first patented stannous-fluoride toothpaste, is a staunch supporter of fluoridating water supplies. But such efforts are not enough, he maintains. Only 155 million of 200 million persons in the U.S. are served by treatable public water supplies. Of them, only 82 million now drink water containing natural or supplemented fluoride. Muhler compounded...
Dent in the Backlog. Putting fluorides to work on a test basis, the Navy has adopted a three-stage treatment. First, each patient is given a basin, a toothbrush, a small cup of pumice paste containing stannous fluoride, and a five-minute lecture on how to proceed. He brushes his teeth for ten minutes. Next, he is plopped into the dentist's chair. A technician spends three to five minutes air-drying his teeth and applying a 10% stannous fluoride solution. Third, the patient gets up to 15 minutes of instruction in how to make daily...
...Navy work to encourage them, more and more civilian dentists seem likely to give their patients a mouthful of one chemical or another as an alternative to the dreaded drill. Dr. Finn Brudevold of Harvard's famed Forsyth Dental Center is concerned that the tin in the stannous fluoride solution commonly used for painting may interfere with the absorption of fluorine, and he is casting around for a better compound. Meanwhile, he says, it helps to cover the teeth, right after painting, with a protective coat of silicone grease. A colleague, Dr. Basil Richardson, believes that the best coating...
...Thank you for publicizing the report of Drs. Hodge and Smith on the benefits of fluoridation [Sept. 3]. TIME'S prestige may favorably influence many fence-sitting communities. Accuracy requires pointing out that conscientious dentists apply stannous and other topical fluoride agents semiannually, not every three years. Also, topical fluorides are supplemental; they are not substitutes for water fluoridation...
