  • Background: Liver disease and transplantation affect bone turnover. The role of cylosporin A (CsA) in aggravating bone loss is controversial. The aim of the present study was to examine the effect of liver cirrhosis, transplantation, and immunosuppressive therapy with either CsA or tacrolimus on alveolar bone height.

    Methods: The experimental group consisted of 13 liver cirrhosis (LC) patients. A second experimental group included 24 post-liver transplantation patients (PT) receiving CsA or tacrolimus. Seventeen healthy subjects formed a control group. Panoramic x-rays were taken and digitized using a computerbased measurement software to assess alveolar bone height of all available teeth.

    Results: Bone loss in the PT group (4.57 ± 0.56 mm) was significantly higher than the control (C) (2.73 ± 0.38 mm); however, it was significantly lower (P = 0.0005) than the LC (6.47 ± 0.75 mm). Likewise, alveolar bone loss showed a trend for negative correlation (R = 0.404, P = 0.06) with the duration of immunosuppressive therapy post-liver transplantation.

    Conclusions: Liver cirrhosis patients demonstrated greater bone loss compared to healthy controls. Restoration of liver functions following transplantation seems to have the potential to reverse some of these radiographic changes. Further longitudinal studies will be necessary to substantiate these findings. J Periodontol 2002;73:313-316.
