title: Impact of endodontic conditions on marginal bone loss.
abstract: This study was undertaken to examine the extent to which the marginal alveolar bone may be influenced by the condition of the dental pulp. A total of 115 pairs of contralateral teeth were observed in 87 patients (25 to 45 years old) in which the test tooth, but not the control tooth, was either endodontically treated or not treated but with a periapical radiolucency. The distance from the cemento-enamel junction to the marginal bone level was measured using intraoral radiographs. The condition of the endodontic filling, the periapical status, and the presence of root canal post were also assessed. With clinical parameters similar between teeth in the two groups in terms of visible plaque, bleeding on probing, probing depth, and attachment level, the results showed a somewhat (mean value 0.1 mm; SD 0.7) larger reduction of the alveolar bone support in test than control teeth. This difference was not statistically significant on a patient level. Hence, this study failed to demonstrate a correlation between a reduced marginal bone support and endodontic status.
