ManagingOralHealthIsanImportantPriorityforHIV-AIDPatients

Forty years have passed since the first reported case of Acquired Immune Deficiency Syndrome (AIDS), and it and the human immunodeficiency virus (HIV) that causes it are still with us. About 1.2 million Americans are currently infected with HIV, with 50,000 new cases diagnosed each year.

The emergence of antiretroviral drugs, though, has made it possible for many with HIV to live normal lives. Even so, the virus can still have a profound effect on health, including the teeth and gums. Because of its effect on the immune system, HIV+ patients are at greater risk for a number of oral conditions, like a fungal infection called candidiasis ("thrush").

Another common problem is chronic dry mouth (xerostomia), caused by a lack of saliva production. Not only does this create an unpleasant mouth feel, but the absence of saliva also increases the risk for tooth decay and periodontal (gum) disease.

The latter can be a serious malady among HIV patients, particularly a severe form of gum disease known as Necrotizing Ulcerative Periodontitis (NUP). With NUP, the gums develop ulcerations and an unpleasant odor arising from dead gum tissue.

Besides plaque removal (a regular part of gum disease treatment), NUP may also require antibiotics, antibacterial mouthrinses and pain management. NUP may also be a sign that the immune system has taken a turn for the worse, which could indicate a transition to the AIDS disease. Dentists often refer patients with NUP to a primary care provider for further diagnosis and treatment.

Besides daily brushing and flossing, regular dental cleanings are a necessary part of a HIV+ patient's health maintenance. These visits are also important for monitoring dental health, which, as previously noted, could provide early signs that the infection may be entering a new disease stage.

It's also important for HIV+ patients to see their dentist at the first sign of inflamed, red or bleeding gums, mouth lesions or loose teeth. Early treatment, especially of emerging gum disease, can prevent more serious problems from developing later.

Living with HIV-AIDS isn't easy. But proper health management, including for the teeth and gums, can help make life as normal as possible.

SedationCanHelpanAnxiousChildRelaxDuringDentalTreatment

There are different ways to ease a child's potential nervousness with dental visits, like starting those visits around their first birthday or seeing a pediatric dentist who specializes in children. But even doing those things won't guarantee your child won't develop some form of dental anxiety, which could complicate their dental care.

To help make appointments easier for anxious children, many dentists use conscious sedation as a means of helping them relax. With this technique, the dentist administers a mild sedative to the child to take the edge off their nervousness, while allowing them to remain awake during treatment.

Sedation isn't anesthesia, the means we use to stop pain during treatment (although sedation may be used with anesthesia). Rather, sedation reduces emotional fear and anxiety. And unlike general anesthesia, a sedated child can still breathe without assistance and, depending on the depth of the sedation, respond to physical and verbal stimuli.

In most cases, children are administered sedation medications by mouth, usually as a syrup, although on occasion it might be delivered intravenously with an IV. The dose is usually given some time before their treatment session after the dentist has evaluated them. Dentists mostly use mild sedatives like Midazolam or Hydroxyzine with very little risk of side effects for children.

During the procedure, a designated staff member continually monitors the child's vital signs. Besides heart rate, pulse and respirations, they may also check the child's exhaled carbon dioxide levels to ensure they're breathing normally.

After the treatment session is over, staff will continue to monitor the child until their vital signs return to pre-sedation levels. If the child is of driving age, they'll need someone to drive them home. Children who've been sedated should remain home for the rest of the day, but they can usually return to school the next day depending on what kind of dental work they've undergone.

Dentists follow strict protocols for pediatric sedation adopted by the American Academy of Pediatrics, the American Dental Society, and the American Academy of Pediatric Dentistry. In addition, many states have also established processes for administering sedation therapy. It's a safe and effective method to ease a child's anxiety over their dental visit.

RemovingTeethMightMakeItEasierToStraightenaSmile

Dentists remove millions of teeth each year, often because of tooth decay or gum disease. But disease isn't the only reason—a tooth extraction might make it easier to straighten a crooked smile.

Realigning teeth for therapeutic or cosmetic reasons is a regular undertaking in dentistry, but the process itself often differs from person to person. Each individual patient requires their own treatment plan taking into account factors like the kind of bite problem involved, the size of the jaw and the space available to move teeth.

This plan could indeed involve removing teeth. For example, an abnormally small jaw could cause crowding. Not only can crowding move teeth out of position, it may also leave little to no room for moving teeth. Although dentists can minimize crowding by influencing jaw development in early childhood, removing teeth for more space is usually the only option available to older adolescents and adults.

Similarly, teeth can fail to erupt properly and remain partially or fully submerged beneath the gums (known as impaction). There is an orthodontic method for pulling an impacted tooth fully onto the jaw, but only if the tooth isn't too far out of alignment. Otherwise, it may be better to remove the impacted tooth and then correct any gaps with braces or a dental implant.

There's also a situation on the opposite side of the spectrum that could benefit from teeth removal—when one or more permanent teeth fail to form, known as congenitally missing teeth. This can cause gaps in the smile or a “lopsided” appearance where a tooth on one side of the jaw is present while its counterpart on the opposite side of the jaw is missing.

The missing tooth can be replaced by an implant, bridge or other restoration. But another option may be to remove the existing counterpart tooth, and then close the gaps. This can result in a much more attractive smile that might be simpler and less costly than replacing the missing tooth.

Again, the decision to remove teeth to improve smile appearance depends on the patient and their particular dental condition. But in the right situation, it could make straightening a smile easier and more effective.

HowAFVsAlfonsoRibeiroSavedHisTooth

Remembered fondly by fans as the wacky but loveable Carlton on The Fresh Prince of Bel-Air, Alfonso Ribeiro is currently in his fifth year hosting America's Funniest Videos. It's the perfect gig for the 48-year-old actor, who loves to laugh and make others laugh as well. This is quite the opposite experience from one he had a few years ago that he remembers all too well: a severely decayed tooth.

After seeing his dentist for an intense toothache, Ribeiro learned he had advanced tooth decay and would need root canal treatment. Ribeiro wasn't thrilled by the news. Like many of us, he thought the procedure would be unpleasant. But he found afterward that not only was the root canal painless, his toothache had vanished.

More importantly, the root canal treatment saved his tooth, as it has for millions of others over the last century. If you're facing a situation similar to Alfonso Ribeiro's, here's a quick look at the procedure that could rescue your endangered tooth.

Getting ready. In preparation for root canal therapy, the tooth and surrounding gums are numbed, often first with a swab of local anesthesia to deaden the surface area in preparation for the injection of the main anesthesia below the surface. A dental dam is then placed to isolate the infected tooth from its neighbors to prevent cross-contamination.

Accessing the interior. To get to the infection, a small access hole is drilled. The location depends on the tooth: in larger back teeth, a hole is drilled through the biting surface, and in front teeth, a hole is drilled on the backside. This access allows us to insert special tools to accomplish the next steps in the procedure.

Cleaning, shaping and filling. Small tools are used to remove the diseased tissue from the interior tooth pulp and root canals. Then the empty spaces are disinfected. This, in effect, stops the infection. Next, the root canals inside the tooth are shaped to allow them to better accept a special filling called gutta percha. The access hole is then sealed to further protect the tooth from future infection, and a temporary crown is placed.

A new crown to boot. Within a couple weeks, we'll cap the tooth with a long-lasting lifelike crown (or a filling on certain teeth). This adds further protection for the tooth against infection, helps strengthen the tooth's structure, and restores the tooth's appearance.

Without this procedure, the chances of a tooth surviving this level of advanced decay are very slim. But undergoing a root canal, as Alfonso Ribeiro did, can give your tooth a real fighting chance.

DrawingImpactedTeethOutoftheGumsCouldHelpNormalizeaSmile

We instinctively know when a smile looks normal—and when it doesn't. It could be that something simply looks out of place like crooked teeth. But we might also notice when something is missing—as with one or both of the canine teeth.

The canine teeth align just under the eyes and are recognizable by their pointed ends. When they're missing, the smile looks “incomplete.” But “missing” in this case could mean “invisible”—the teeth are there, but hidden within the gums because they failed to come in properly and became impacted. This often happens on a smaller jaw where other teeth have crowded into the space intended for them.

Fortunately, we may have a remedy, and not just for appearance's sake—any impacted tooth can cause health problems, from gum abscesses to root damage of neighboring teeth. Although this might necessitate their surgical removal, we might also be able to coax them through the gums into better position in the jaw, if they're in a reasonably good position. This could result in both a boost to a patient's oral health and a more normal looking smile.

First, though, a patient will need to undergo a thorough bite evaluation by an orthodontist. Besides pinpointing the impacted teeth's precise location with x-rays or CT technology, an orthodontist will also want to assess the positions and condition of the rest of the teeth. If the conditions are right and there's enough room in the jaw, the orthodontist may recommend drawing the impacted canines into proper alignment in the jaw.

The process starts when an oral surgeon exposes the impacted teeth by surgically cutting through the gum tissue. They then attach a small bracket to the tooth with a tiny metal chain attached, the other end of which is looped over orthodontic hardware attached to other teeth. The tension on the chain by the hardware gradually nudges the teeth downward out of the gums. This is usually done in coordination with other measures to fully correct the bite.

If the procedure is successful, bringing the canines out of impaction reduces the problems those teeth could cause the person's oral health. But just as important, it can restore normality to their smile.
