title: [Endodontics in periodontology].
abstract: Every pulp disease extending beyond the apical foramen will affect the periodontium. On the other hand, a periodontal lesion may cause an infection of the pulp via the apical foramen or via accessory canals. Finally, a tooth may be affected by both periodontal disease and pulp disease that were independent from each other, but have merged. In the literature so far there have been only few studies dealing with these interrelationships. After explaining the pathogenesis of these diseases a classificiation is given which is based on etiology. For the diagnosis a detailed case history clinical findings, and radiograms possibly using contrast media are required. This also enables differential diagnostic delimitation and provides the basis for causal therapy.
