The periodontal pocket cleaner is a device for removing material from a periodontal sulcus or periodontal pocket and for ascertaining and monitoring bleeding and suppuration within the sulcus or pocket. The pocket cleaner is a disposable item composed of a soft hardwood or similarly appropriate wood. It has an elongated narrow shape with the grain of the wood parallel to the direction of elongation. The device tapers to a functional point at one end enabling this tapered end to be easily inserted into the sulcus or periodontal pocket. The tapered end of the pocket cleaner is softened by being moistened before being inserted into the sulcus or pocket. The tapered end of the pocket cleaner is used to scoop material from the sulcus or pocket, to scrape plaque from the tooth surfaces adjacent to the sulcus or pocket, and to absorb blood and other suspended components from the sulcus or pocket. By virtue of its small size, narrow shape, wooden composition, softness, and pliancy, the pocket cleaner minimizes the deformation and abrasion of the detached gingival tissues which form the sulcus or pocket. In spite of its small size and narrow shape, the moistened pocket cleaner usually maintains sufficient strength to clean several sulci and pockets. The absorbent wood of the pocket cleaner also provides the vehicle for the delivery of medication as a complement for the treatment of infections within the deeper recesses of pockets.
