Recently developed for the treatment of periodontal disease, the perioscope is a device used to examine the space under the gum of areas subjected to periodontitis. The tool captures images of the diseased tooth and its surrounding area so the clinician can inspect the root surface and periodontal pocket to check for bacterial accumulations.

With the help and guidance of the perioscope, the clinician can treat periodontitis by locating and removing plaque and calculus that has accumulated on the root surface. It also allows the clinician to identify cracks, perforations, and other imperfections that may cause disease—previously only identifiable with surgery.
