The goal of modern periodontal therapy, both during the initial stages and during maintenance, is to create biologically acceptable tooth surfaces through sub- and supragingival cleaning, which enables binding of the connective tissue to the greatest extent possible. In past centuries, the focus of periodontal treatment was on the removal of the supposed cause of periodontal disease, the supra- and supragingival calculus and "infected" root cementum. The findings on the importance of biofilmA51_FootRef1/A51_FootRef(plaque) and the endogenous responses to biofilm metabolism have shifted the therapeutic focus to elimination of the biofilm. The importance of avoiding injury to the hard and soft dental tissue is nowadays of upmost importance. For classical scaling and root planing to remove mineralized deposits and "infected" cementum, only hand instruments were available in the past. The regular, long-term use of these tools is associated with changes in the hard and soft tooth tissues, and with pain and sensitivity experienced by the patient during and after treatment. Modern root-surface debridement primarily uses ultrasound systems to remove hard mineralized deposits. For biofilm management, air polishing devices with low-abrasive powders are increasingly gaining acceptance. With this new technology, biofilm management can now be performed much more effectively and efficiently, using materials more sparingly; this also causes less pain and discomfort for patients during and after treatment, and less fatigue for practitioners. The modern systems allow gentle, optimal biofilm management, whereas the traditional hand instruments (curettes, scalers) and classic rotating instruments used for polishing do not. Current knowledge suggests that these instruments are not best suited for biofilm management. |
