...million people in the U.S. are exposed each year to diagnostic medical X rays; 50 million have dental X rays; 8,000,000 are fluoroscoped. According to Karl Z. Morgan, health physicist on the 1943 Manhattan Project and now at Oak Ridge National Laboratory, many of the millions are probably being dangerously overexposed to radiation. Before the Senate Commerce Committee last week, Dr. Morgan admitted that statistics on radiation hazards are guesses at best-but he suggested that anywhere from 3,500 to 30,000 U.S. deaths may result each year from the cumulative effects of radiation...
Several Lacks. Whatever the current cost in lives and health, X-ray diagnosis is enormously beneficial, Dr. Morgan declared, and undoubtedly saves many tens of thousands of lives annually. The trouble, he emphasized, is not in the available equipment: everything that is needed to reduce the national total of dental X-ray doses to 1% of the current level, and to reduce all diagnostic exposures to 10%, is already perfected and on the market. The fault, said Dr. Morgan, lies in poor techniques, the use of improper (usually old) equipment, the lack of concern by doctors, dentists and technicians...
Fathom is yet another lifelike vinyl imitation of spy spoofs, starring Raquel Welch in a title role painful enough to make Modesty Blaise cry U.N.C.L.E. A toothsome dental assistant, Fathom spends her holiday sky-diving in Spain. Recruited by British agents, she becomes involved in a labyrinthine scheme to recover the Fire Dragon, a bejeweled piece of china stolen from Peking...
Into the Labs. Last week's workshop demonstrated that professional apathy has begun to wane. In the universities and in the National Institute of Dental Research, most of the focus is on periodontal disease, which actually claims three times as many teeth as do cavities when people are past 35. To date, the main preventive treatment has been regular cleaning to remove the bacteria-containing film and tartar. Within two years, several commercial firms may be marketing new anti-periodontal-disease products in the form of toothpastes and mouthwashes...
Barnacles & Baboons. Dental researchers have not ignored improvements in treatment. In another NIDR study, Dr. Nathan Cardarelli has been analyzing barnacle cementum with the idea that a similar synthetic substance might provide an almost indestructible tooth filling. Dr. Robert Hoffman of the Waldemar Medical Research Foundation has demonstrated for the first time that a metal can be welded firmly to dental enamel by ultrasonic vibrations. He hopes to use that method to replace missing teeth and damaged tissues. Working toward the possibility of a "tooth bank," the NIDR Dr. Paul Baer has already nurtured teeth in the yolks of incubating...
