[Effective treatment of periodontitis].

Based upon clinical periodontal parameters and roentgenographic diagnosis a temporary treatment plan is made, which results in a definite one after the initial treatment. Only a rigorous removal of dental plaque guarantees an effective and efficient working manner, which starts with indirect scaling and rootplaning sustained by the personal oral hygiene. If the indirect therapy appears to fail, the roots must be cleaned under direct view. After the active phase, the supportive treatment takes place every three months, assessed to be of equal importance.
