ENDO/PERIO LESION

The relationship of the pulp and the periodontium is dynamic. The periodontium and the pulp areclosely related, they have embryonic, anatomic and functional interrelationships. In 1919 Turnerand Drew first described the effect of periodontal disease on the pulp. The relationship betweenperiodontal and pulpal disease was first described by Simring and Goldberg in 19641. The clinicianshould be aware that endodontic and periodontal lesions arise from inflammation or degeneration of both tissues. The function of a tooth depends on the health and vitality of the periodontium and not on the state of the pulp. Thus, the tooth and its supporting structure form a biological unit.
