title: [Results of follow-up studies of endodontically treated teeth based on punched-card records and visual comparison during systematic periodontal treatment].
abstract: The relationship between periodontal alterations in the marginal and the apical areas led us to question whether or not a tooth should be conserved when periodontal alterations are present in both areas. Comparison of edge-notched cards showed that the conservation of individual teeth and/or groups of teeth following periodontal treatment does not depend on endodontic care.
