A study conducted by researchers from the University of California San Francisco suggests an approach to cavity prevention called CAMBRA (Caries Management By Risk Assessment) in an effective way to reduce tooth decay. This approach includes a tooth-decay risk assessment, aggressive preventive measures, and conservative tooth restorations.
According to researchers, CAMBRA may help transform dental care for patients at high risk for cavities, also called dental caries. Previous studies showed the method is effective in a clinical setting and this latest research suggests it also works in the community.
Tooth decay occurs when bacteria in the mouth feed on carbohydrates on the tooth surface and produce acids that destroy the tooth enamel and the dentin beneath it. Dentists who use the CAMBRA method first evaluate the patient's dental and medical history and then conduct a clinical exam to assess cavities and reverse or stop the decay process. They also assess risk factors such as the presence of acid-producing bacteria, frequent snacking, and low levels of saliva in the mouth, and then create an individualized plan to prevent cavities.
