ABSTRACT:
A process for treating periodontitis existing in the mouth of a patient having teeth with roots extending downwardly in the gums by using a scaler including a scraper with a cutting edge and a handle for the scraper. A dentist uses the scraper to remove tartar, concretions and necrotic root element from a tooth by guiding the cutting edge along the tooth root under the gums from the lowest point of the gum pocket and while exerting pressure on the root suddenly moving the cutting edge with a powerful jerk in scraping manner toward the chewing face of the tooth. The scaler is adapted for manual movement by the dentist and also has a mechanism which when actuated initiates and performs the jerk action without manual movement of the scraper by the dentist.
