Technology-enhanced caries detection and diagnosis

The prevalence of dental caries in children and adults in the United States has been declining the past 40 years primarily because of increased use of fluoride, improved oral hygiene and better oral hygiene devices, a greater emphasis on disease prevention and control, and better access to dental care made available by the dental profession. Caries diagnosis and detection for pit-and-fissure lesions has changed dramatically in the past 25 years. Research has confirmed that the carious process is bacterially mediated and is accompanied by changes in salivary flow and pH and the intake of refined carbohydrates. In recent years a number of new technologies have become available as adjuncts to traditional methods of diagnosing carious lesions. While using these new technologies, the clinician still needs to understand the concepts of caries risk, diagnosis, detection, and assessment. Working from the evidence, dental practitioners can decide on a sound clinical diagnosis and treatment plan.
