The preparation of the tooth is complete. The walls of the cavity seem hard to the explorer. There is no telltale brown decay visible, even under magnification. Therefore, the cavity must be clean, and ready for restoration. FIG. 1 Or is it?
If cariogenic bacteria are retained at or below the tooth-restorative interface, the long-term health of the remaining tooth structures, as well as the longevity of the restoration will be compromised. 1For the practitioner, this is a significant issue that will determine short and long term clinical success and one that is not readily diagnosable with currently available tools and technologies. Ozone treatment has been proven to be an excellent antimicrobial agent and is now in use many thousands of practices around the world.20-23 Photo-Activated Disinfection (PAD) is an innovative technology that utilizes two non-toxic components, a photo-activating liquid and an LED light source to selectively tag and destroy cariogenic bacteria and periodontal pathogens. PAD instruments have been evolving for two decades, and the Aseptim Plus (SciCan, Toronto, Canada) is the current state of the art in the photo-activation treatment category. FIG. 2
