Predictions Can Come True in Dentistry

I see lots of predictions at this time of year and it is interesting to see how close they are to reality.

In dentistry, new predictive tools that indicate whether a person will get cavities are very close. New technology is helping dentists move from treating disease, that is waiting for a cavity to form and repairing the tooth, to emphasizing prevention and wellness -- by determining which individuals are at greater risk for cavities and showing them simple interventions that may save them from getting dental disease.

Researchers have perfected a technique called ATP-bioluminescence that measures the energy source for the cavity-causing bacteria in an individual’s mouth. And interestingly, the results are as accurate --and possibly even more accurate -- than sending mouth swabs to a lab for analysis. The energy source is called ATP.

A hand-held test is now available for use in the dentist’s office that measures the amount of ATP in the cavity-causing bacteria of a patient’s mouth with an instrument about the size of a television remote control. As part of a routine exam, the dental hygienist simply takes a swab sample from the patient’s teeth and in fifteen seconds, the device analyzes the energy in the bad bacteria. Counts below 1,500 are seen as “good” and those reaching 10,000 are “bad”.

Bad does not mean that you are doomed to a mouthful of cavities. But it will alert your dentist that intervention is needed. The first step may be to reduce the acidity in your mouth, and therefore reduce the energy available to feed the cavity-causing bacteria. Your dentist may suggest brushing with baking soda toothpastes or using specially formulated mouth rinses which reduce acid levels and help reduce or eliminate cavities for you.

Dentists also strongly recommend the use of prescription fluoride gels and rinses which help small cavities heal themselves. Another good idea is to use products (like chewing gum) sweetened with xylitol instead of sugar because xylitol has been shown to reduce the risk of forming new cavities.

ATP-bioluminescence looks promising. It will be interesting to hear what dental offices think about this new technology as way to help patients prevent dental disease.

I am always on the look out for details about new technological advancements in dentistry, especially those which promise to help patients and their dentists prevent disease. There is currently some very innovative research underway that may lead to surprising health outcomes. I’ll be bringing them to your attention as I learn more about them.
