Dental Care And A New Diagnostic Tool For Mouth Cancer

According to the American Cancer Society, about 30,000 new cases of mouth cancer are diagnosed annually in the U.S. About half of those who have oral cancer die within five years. Early detection can make a dramatic difference in treating the cancer at curable stages and reducing oral cancer deaths.

Early detection capabilities recently have been enhanced by a new computer-assisted mouth cancer screening tool. A nationwide study of 945 patients ranging in ages from 18 to 83 was conducted by dentists at 35 U.S. academic dental care sites.

Brush biopsy specimens were obtained from oral lesions as part of the extensive research, testing the accuracy of computer-assisted diagnostic equipment. The brush biopsy caused little or no bleeding and no anesthetic was required. The computer-assisted image analysis was used to identify suspicious cells in the samples.

The computer analysis properly identified every case of pre-cancerous and cancerous lesions as confirmed by lab tests from their traditional tissue evaluations. Additionally, it also correctly identified some lesions that were benign in appearance, but were actually found to be pre-cancerous or cancerous. Had it not been for this new diagnostic equipment, these lesions would have escaped detection and the patient would not have received any additional oral cancer testing.

"Early evaluation of oral pre-cancerous lesions can have a dramatic impact on oral cancer mortality rates," says Dr. James J. Sciubba, DMD, PhD, professor of Oral and Maxillofacial Pathology at State University of New York at Stony Brook, who also serves as a spokesperson for the study. Early-stage mouth cancers are not easily detectable by visual inspection and may be overlooked.

The oral cancer scanner provides dentists a new evaluation tool that can lead to a significant reduction in cancer deaths. An estimated 8,100 people will die from mouth cancer this year. This new dentistry tool has shown remarkable merit as a reliable dental health device. By providing an accurate diagnosis, it has become a crucial weapon in the fight against oral cancer.

Family Dentistry: Dental Hygiene and Your Dental Care Team

The new dentistry brings together a unique complement of skills, knowledge, and capabilities with one primary focus: ensuring your dental health. Working as a team, your dentist and the dental team he or she has assembled wants to recruit you to join them in making sure this focus is maintained. The dental team has two major parts that you may hear referenced during your visits: the "back" and the "front." These terms refer to two very specific functions of your dental team. The front office handles all the administration, scheduling, and financial details, and the back office provides the treatment.

Your front office team makes sure you know about scheduling opportunities, handles finances, and keeps the administrative details under control to provide you efficient services and support. The back office team is thus free to do what they do best: provide the best care and service for you. You'll find the dentist, dental hygienist, and dental assistant ready to assist you during your appointments.

The key component for success of any team is each member's commitment to do their part. As a consumer and team member, your commitment involves three things:

1. Maintaining your commitment to your dental health through regular dental hygiene appointments and the daily practice of flossing and brushing.
2. Asking questions and getting the essential information you need about your teeth and gums or to understand any treatment plans.
3. Staying open to options and opportunities that the new dentistry offers you by thinking about the information and feedback that your dentist provides you about the status of your dental health.

You can maximize the benefits of the skills and expertise of your dental team by deciding for yourself what kind of relationship you want with your dentist and the dental team and how they can help you achieve a positive outcome for your dental future.

Bad breath, or halitosis, is a signal that something is not right inside your mouth. It may be as simple as the need to pay more attention to your daily dental hygiene, or it may indicate tooth decay, gum disease, or another medical problem. Whichever it is, bad breath is a red flag: take another look at your mouth!

Bad breath is a social problem; if you have bad breath, you may notice that people actually back away as you talk to them. Mouth odors are embarrassing, and they tell other people that you aren't taking care of yourself. Sometimes people are not aware that their breath smells bad; be alert to how other people react when they're close to you, and be grateful if a friend or family member lets you know about the problem.

Commercial products claim they will make your breath fresher, but the only way to make sure your breath permanently fresh is to practice good oral hygiene. In fact, too many breath mints and hard candies with sugar will lead to tooth decay. If you are constantly using breath mints, breath sprays, or mouth rinses in an effort to cover up your bad breath, realize that you may have a dental or medical problem that needs addressing.

There are a number of reasons you may experience a bad taste in your mouth, and even be able to smell your own breath. Food may be lodged between your teeth if you are not brushing at least twice daily and flossing regularly. Food particles can be very tiny and can wedge themselves between teeth and below the gum line; brushing after meals is important and flossing is imperative to get at the particles that the brush can't reach. Brush your tongue or use a tongue scraper. As odd as it will feel at first, bacteria collects on the tongue and can contribute to bad breath. If you wear removable dentures, take them out at night and clean them thoroughly before you wear them again.

If you neglect your daily dental hygiene over time, bad breath can become a symptom of more serious dental problems. Teeth that are not cleaned properly become a place for bacteria to reside as food particles stay in your mouth and decay. Bacteria attack your teeth and gums and cause cavities and gum disease. If this is happening, gum disease will cause an unpleasant odor.

Perhaps you believe that you are brushing and flossing on a regular basis, but are still experiencing bad breath. If you have teeth that are crooked or crowded, it may be hard for you to clean between them. If you wear dentures that are not fit properly, they may be trapping food or irritating your mouth. Or perhaps your bad breath is caused by another medical problem: drainage from your sinuses, gastrointestinal problems, kidney or liver problems, or other medical conditions.

Here's what you can do to "investigate" on your own. Write down what you're eating and notice whether your breath smells bad because of certain foods. Garlic and onions actually cause odor, but the odor is coming from your lungs as you breathe, not from your mouth itself. The odor from these foods is temporary, and will be gone once the food is out of your bloodstream.

Are you dieting? Hunger can contribute to bad breath, because of the chemical changes as your body turns fat and protein into the energy it needs. Taking prescription or over-the-counter medications? Add these to the record of what you're eating to see whether there's a relationship between your medications and your bad breath. And don't forget to tell your dentist if there's been a change in your overall health since your last visit.

Suffering from dry mouth? Saliva provides constant rinsing in our mouths and washes away food particles. Your dentist may recommend more liquids, sugarless candy to stimulate natural saliva, and perhaps some of the commercial products that are available to combat dry mouth.

If bad breath continues after you have done your best job of regular brushing and flossing, start with your dentist. He or she can tell you whether the odor is caused by an oral problem; if it is not, then your dentist will suggest you see your doctor for a physical check-up.

Regular dental check-ups will help keep your mouth healthy and working well. Your dentist can spot problems before they cause trouble, including problems that cause bad breath.
