Every time you lose a tooth, your life gets shorter. That’s the conclusion researchers at Göteborg University, in Göteborg, Sweden reached — at least when it comes to people over 70 — when they compared dental records to mortality rates. “The results showed that each remaining tooth at age 70 decreased the mortality risk by 4 percent over 7 years, and 2 percent – 3 percent over 18 years,” wrote
The University of California, Los Angeles (UCLA) dental school faces twin allegations this week: That students cheated on national board exams and that applicants to the university’s orthodontics residencies are being asked for donations in return for admission. The accusations against the orthodontics program stem from an investigation by the Daily Bruin, the UCLA student newspaper. It reported Tuesday that admissions officials were asking applicants for hefty donations, a practice
What do Russell Crowe and Septocaine have in common? They have both won prestigious awards in their fields. (And they both make us numb with delight.) The latter was named the No. 1 product CRA evaluators “can’t live without” in the September issue of the CRA Newsletter. Over 400 CRA dental teams nominated 830 products; the top 11 were featured in the newsletter. Top products included adhesives, optical tools, CAD/CAM
The proportion of American youths who visit the dentist regularly has edged up slightly, according to the U.S. Agency for Healthcare Research and Quality (AHRQ). Crunching numbers from a 2004 survey, the agency found that 45 percent of Americans 20 years old or younger visit a dentist at least once a year. Still that was only a tiny increase over 1996, when a similar survey showed 42 percent of youths
Before you can slap on a ceramic veneer, you have to prepare the teeth. You need to remove some material — but not too much. And you need to remove it uniformly. A new ally in this delicate operation could be Komet USA’s Kit 4517, which is designed to give you enhanced control over tooth penetration before applying ceramic veneers. “An important precondition for successful placement is conservative tooth structure

Slap on some hydrogen peroxide and it’s amazing what disappears from a tooth: bacteria, wine stains, even tetracycline coloring. But dental researchers have long wondered if anything more important disappears as well — such as some of the tooth itself. And in a recent spate of studies, they’ve come up with worrisome answers. Enamel, it seems, can tolerate a pretty harsh splash of bleach. But dentin is another matter, says
You think parallel parking your SUV in a Corolla-sized space is tough? Try putting a dental implant in just the right spot in someone’s mouth. In many cases, you don’t know what you’re facing until you expose the patient’s bone. “There are many unknowns that are hidden until the time of surgery,” said Dr. Joseph Califano, program director of periodontics at the University of Illinois at Chicago, in a press
3M Unitek has introduced Clarity SL braces — clear, self-litigating braces made from translucent ceramic. These braces use a clip to hold the wires in place eliminating the need for elastic bands (ligatures). “For the first time, adults and children who need braces no longer have to trade off looks or performance to achieve a beautiful smile,” said Anoop Sondhi, D.D.S., M.S., an orthodontist in a press release. “Clarity SL
Collagen Matrix announced that the U.S. Food and Drug Administration (FDA) has cleared its SynOss synthetic material, a type of artificial bone, for oral surgery. The company said it had received 510(k) clearance for the bone substitute, meaning the FDA deems it at least as safe and effective as materials previously approved for the same purpose. SynOss synthetic mineral is an osteoconductive calcium phosphate-based bone graft material. Unlike hydroxyapatite materials,

These subscription-based retainers will be delivered to dentists or directly to the patient four times a year. “Vivera retainers were created to fit the needs of patients’ busy lifestyles,” said Rick Matty, general manager, new products at Align Technology in a press release. “Not only do patients get the
In Noorvik, Alaska where Aurora Johnson grew up, you don’t have to look very hard to see the importance of dentistry. The nearest dentist is an expensive plane ride away, and many Noorvik residents can’t afford the trip, much less the dentist’s bill. As a consequence, “a lot of my classmates in high school graduated with little or no teeth,” says Johnson. Motivated by this first-hand experience, Johnson, 36, now
