| [significance of the bacterial flora in the etiology of apical periodontitis. qualitative, quantitative and topographical aspects]. | in the international literature it is shown the central role of root canal infection in the etiology of periapical lesions. as a matter of fact it has been proved (13) that sterile necrotic pulp tissue is completely unable to cause inflammatory reactions at the periapex. infection of endodontic origin extends to the supporting tissues of the tooth only in the case of their acute inflammation (e.g. acute apical periodontitis, acute alveolar abscess, phoenix abscess). on the other hand in chronic ... | 1990 | 2135040 |
