When it comes to the attractiveness of orthodontic braces, less metal is better, according to a survey published in the American Journal of Orthodontics and Dentofacial Orthopedics (April 2008, Vol. 133:4, pp. S68-S78). The study of the public’s attitude about the attractiveness of various styles of braces indicates that the types of dental appliances with no visible metal were considered the most attractive. Braces that combine clear ceramic brackets with
When dentists and their staff ask their patients simple questions, they shouldn’t expect truthful answers. That’s the take-home message of a recent survey, in which more than four in 10 adults admitted they would tell their dentists they always brushed for the recommended time — even if it weren’t true. One in four, meanwhile, said they would fib about flossing, too, according to a Harris Interactive poll of 1,001 U.S.
NEW YORK (Reuters Health), Jul 7 – By maintaining adequate vitamin D levels during pregnancy, mothers may be protecting their babies against early tooth decay in childhood, according a study reported Friday at the International Association for Dental Research (IADR) meeting in Toronto, Canada. Dr. Robert Schroth from the University of Manitoba reported that mothers of children who developed cavities at an early age had significantly lower vitamin D levels
TORONTO – Speakers at the International Association for Dental Research (IADR) meeting on Thursday called for wider adoption of glass ionomers for restorations, linings, and bases. First developed in the U.K. in the 1970s, glass ionomers have long been used in Europe, Asia, and developing countries for restorative and lining purposes, offering a readily available, cost-effective alternative for caries treatment, particularly in children. But their use in the U.S. has
TORONTO – Acupuncture might calm patients who fear their dentists, but there isn’t enough evidence yet to recommend this approach. So said researchers from King’s College in the U.K. at the annual meeting of the International Association for Dental Research (IADR) on Wednesday. The researchers headed by Nora Donaldson, Ph.D., M.Sc., searched Medline, EMBASE, the Cochrane database, and several complementary medicine databases for studies on acupuncture for dental anxiety. Discarding
KUALA LUMPUR (Reuters Life!), Jun 20 – Doctors warned parents in Asia on Friday not to take hand, foot, and mouth disease (HFMD) lightly as it is increasingly associated with complications like encephalitis, which can be fatal. HFMD affects mainly children younger than 10 years old. In the past, it was mostly caused by the coxsackievirus A16 and complications were rare. But another little-known agent, enterovirus 71 (EV71), has crept
NEW YORK (Reuters Health), Jun 19 – Baseball, the American pastime, appears relatively safe compared with other high school sports, researchers report. Nonetheless, injuries do occur and many could be prevented, they say. About 12% of high school baseball injuries result from players being hit by a batted ball, and nearly two-thirds of these injuries are to the head and face or mouth and teeth, said Christy Collins, of the
When it comes to deep carious lesions, conventional wisdom (i.e., G.V. Black) has long said that “it is better to expose the pulp of a tooth than to leave it covered only with softened dentine.” But for years some have questioned whether completely removing the infected dentin from lesions approaching the pulp is always necessary. Clinical studies supporting partial caries removal and stepwise excavation have shown, in fact, that these
Gov. Arnold Schwarzenegger signed legislation last week that made California the first state to establish a self-regulating agency for dental hygienists. Effective January 1, 2009, Bill 853 calls for the creation of a Dental Hygiene Committee, a regulatory body under the California Dental Board that will oversee the state’s dental hygiene profession. The committee will be charged with licensure, education, and enforcement of dental hygiene, according to a press release
Periodontist Tom Wilcko and orthodontist William Wilcko’s “accelerated orthodontics” technique has become well-known for its ability to significantly speed up the teeth-straightening process and give patients a healthy bite in months rather than years. Now researchers at the University of Southern California (USC) say they have further improved the outcome of periodontally accelerated osteogenic orthodontics (PAOO) by using a different grafting material: human bone. With PAOO, a periodontist or oral
Imagine shopping for a car if the only make was Ford. Or dining out if the only place to eat was Sizzler. For 21 years, that has been the situation dentists faced if they wanted to make crowns and other restorations in their own offices. This year, the scenario changed. After years of advance publicity, Dallas company D4D Technologies launched its E4D CAD/CAM system in the first-ever direct challenge to
