The DentalView DV2 Perioscopy SystemTM (DentalView Inc., Lake Forest, CA, USA) was designed to visualize the subgingival environment for diagnosis and to aid the treatment of periodontitis. This instrument consists of a 0.5 mm diameter fiber-optic strand. This strand is inserted into a sheath, which provides a sterile barrier between the patientís tissue and the perioscope. The sheath is connected to a peristaltic pump, which conducts a flow of water around the strand to the strandís end to irrigate the working field. The end of the sheath has a sapphire lens that ocuses on the toothís surface and sends the image back through the fiber-optic strand to a video sensing chip camera (CCD). The image is then displayed on an active matrix LCD-TFT monitor. Using the perioscope, clinicians are able to visually explore the gingival pocket, finding the precise location of the biofilm, root deposits, granulation tissue, caries and root fractures.
