[Prevention and early treatment of gingivitis and periodontitis].

The presence of dental plaque leading to gingivitis is regarded as the most important cause of periodontitis which develops from gingivitis. The destruction of the periodontal tissues may be accelerated by functional disorders of the masticatory apparatus. Chemical prevention and therapy is still in its initial stages with their future being uncertain. On the other hand, prevention and therapy of periodontitis are possible by hygienic measures. The mechanical removal of dental plaque and calculus is the best way of prevention and early treatment. This is shown with the aid of a clinical study.
