Braces for the Young Crowd

If you walk the halls of an elementary school, you’re likely to see a lot of “metal mouths.” Many parents are now opting for early orthodontic treatment, and the American Association of Orthodontists recommends that children see an orthodontist for an evaluation no later than age 7. But research shows there are often advantages to deferring treatment, though decisions are made on a case-by-case basis.

“There’s been a number of studies that have shown for some very common problems that you’re better off waiting until all the permanent teeth have come in first before treatment is started,” said Robert Williams, a board certified orthodontist who teaches at the University of Maryland.

Common problems that fall into the “better-to-defer” category include conditions such as overjets—that’s when teeth protrude or stick out—or crooked teeth that just need simple straightening.

New Study Reveals Shocking Levels of Gum Disease

Chief Executive of the British Dental Health Foundation, Dr. Nigel Carter, issued new fears following a study that suggested the prevalence of periodontal disease in the US may have been underestimated by as much as 50 percent.

“The study shows that gum disease is a bigger problem than we previously thought and although this news comes from across the Atlantic, it could well apply to us here in the UK as well,” Dr. Carter said. “In this instance, the best course of action would be one of caution, given what is understood about the links between gum disease and other systemic links such as heart disease, strokes, diabetes and pre-term births.

“It all means that the relationship between gum disease and other related illnesses now becomes even more critical, in light of these new findings. In order to better understand the full extent and characteristics of periodontal disease in the UK a full and comprehensive study needs to be carried out on our adult population.”

Dentists Help to Detect Fetal Alcohol Spectrum Disorders

Fetal alcohol spectrum disorders (FASD) is an umbrella term that describes the range of effects that can occur in a person whose mother drank alcohol while pregnant. Each year, FASD affect an estimated 40,000 infants in the United States—more than spina bifida, Down syndrome, and muscular dystrophy combined. Dentists have found themselves to be in a unique position to aid children with FASD because they may often see patients on a more frequent basis than a physician.

Defects caused by prenatal exposure to alcohol have been identified in virtually every part of the body. These areas include the brain, kidney, heart, ears, bones—and face. Dentists are now learning how to spot orofacial characteristics that often affect children with FASD, according to an article published in the September 2010 issue of AGD Impact, the monthly newsmagazine of the Academy of General Dentistry (AGD).

Kentucky Tries to Improve Dental Care

Residents of Kentucky want to change the way they’re perceived. They don’t want to be judged specifically on what their smile looks like.

That’s why the state implemented a law that forces children to have proof of a dental screening or examination by the time they enter school. The law took effect this year but was passed in 2008.

About 42 percent of Kentucky children from ages 2 to 4 have some kind of tooth decay that hasn’t been treated. That’s why the state government decided it needed to create the law.

Kentucky’s dental problems don’t end there, however. The state has one of the highest rates of toothlessness and had the worst rate in 2002. The rate has since improved, but it can improve even more.

Taste Genes Predict Tooth Decay

Dental caries is a highly prevalent disease that is disproportionately distributed in the population. Caries occurrence and progression is known to be influenced by a complex interplay of both environmental and genetic factors, with numerous contributing factors having been identified, including bacterial flora, dietary habits, fluoride exposure, oral hygiene, salivary flow, salivary composition, and tooth structure. Previous reports have characterized the influence of the genetic variation on taste preferences and dietary habits.

In an article published in the Journal of Dental Research titled “Taste Genes Associated with Dental Caries” lead researcher Steven Wendell and researchers Melissa Brown, Margaret Cooper, Rebecca DeSensi, Mary Marazita, Xiaojing Wang and Robert Weyant, all from the University of Pittsburgh; and Richard Crout and Daniel McNeil from West Virginia University, hypothesized that genetic variation in taste pathway genes (TAS2R38, TAS1R2, GNAT3) may be associated with dental caries risk and/or protection.
