Lecture
Topic : Early Detection and Management of Oral Disease

Synopsis :

Traditional paradigm in dentistry was a surgical model that visually detects late stage lesions and then removes them surgically. However, there has been increasing needs for the traditional paradigm to change. A new paradigm in dentistry is a nonsurgical approach which allows early detection of the oral disease, followed by minimal invasive dentistry. For this to be achieved, a high-technology detection device recognizing changes in the earlier stages which could not be visually observed is needed.

The current optical fluorescence technology for detection of biofilms has focused to the red fluorescence of bacteria induced porphyrin. Among these medical devices, quantitative light-induced fluorescence (QLF) conspicuously stands out among the newly released devices. QLF technology is the quantitative visible blue light induced fluorescence system which can capture changes in mineral contents and bacterial porphyrin induced red fluorescence at high resolution. This technology can detect not only dental caries but also mature plaque and dental calculus. During the growth phase of the dental biofilm, secondary colonizer bacteria produce a unique bacterial metabolite called porphyrin. These porphyrin-containing biofilms manifest as red QLF, and the fluorescence intensity is significantly correlated with various variables related to dental caries. The red fluorescent biofilm detected using QLF is a mature plaque existing on the tooth surface that has been present for at least 3 days. This optical fluorescence technology can extend its detection area which can evaluate oral malodor from tongue coating and interproximal plaque. The most recent florescence technology can distinguish the individual species of oral bacteria using other advanced fluorescent technology. In this presentation, the various clinical applications of this optical fluorescence technology in the dentistry will be introduced.

Dental biofilms are the main causes of oral disease which are groups of microorganism to accumulate to a surface. As biofilm grows, pathogenicity gradually increases. It is well known that this dental biofilm are main cause not only dental disease but also serious systemic disease such as cardiovascular disease, diabetes and aspiration pneumonia. If the pathogenicity of dental biofilms can be detected by optical fluorescence technology, it will be a useful tool in clinical dentistry.  
After detection of early stages of oral disease, early management will be needed to suggest the solution. Fluoride is the representative chemical compounds to remineralize the early dental caries from long time ago. This presentation will share the recent information about the paradigm changes in fluoride mechanism for caries prevention and modern clinical protocol. This lecture will also introduce new methods of applying various chemical agents to the oral cavity over a long period of time.
