    Notes: Abstract Within the framework of an on-going prospective clinical study begun in 1985, 120 adhesive-fixed partial dentures (AFPD) continued to be examined. The manufacture and the fitting of the AFPDs were carried out following a standard procedure. The preparation technique and the metal framework conditioning (silica-coating, sandblasting and electrochemical etching) has varied throughout the duration of the study. Using Kaplan-Meier analysis, the survival rate was determined and an analysis of risk with regard to location factors (anterior, posterior; maxilla, mandible), conditioning and preparation techniques (retentive/non-retentive) was determined using the Cox regression model. The location of the AFPD had no influence on the survival rate. The survival time was determined mainly by the preparation technique. Strict preparation of seating grooves and pin holes made a 95% survival rate possible after 10 years (Kaplan-Meier estimation). Without retention, the risk of failure increased by a factor of 3.7.

    Description / Table of Contents: Zusammenfassung Unmittelbar nach Injektion von 0,05 µCi14C-Bilirubin wurden bei 7 Personen 62,5 mg/h (Dosis I), bei 5 Personen 312,5 mg/h (Dosis II) und bei 6 Personen 625 mg/h (Dosis III) unkonjugierten Bilirubins kontinuierlich intravenös 4 Std infundiert. Es wurden die HalbwertszeitenH 1 undH 2 der hepatischen Bilirubinaufnahme und Konjugation bestimmt und mit einem Normalkollektiv (n=15) verglichen.H 1 zeigt bei Dosis I, II und III leichte Erhöhung, keine signifikanten Unterschiede bestehen zwischen diesen Dosen.H 2 zeigt bei Dosis II und III eine signifikante Senkung gegenüber der Norm. Die Serumbilirubinkonzentration erreichte nach 120 min (Dosis I und II) bzw. 180 min (Dosis III) ein Maximum (maximale Konzentration bei Dosis III 12,6 mg-%), um weiterhin bis zur Beendigung der Infusion konstant zu bleiben.
    Notes: Summary Immediately after intravenous injection of 0.05 µCi14C-bilirubin, a continuous infusion of 62.5 mg/h (dose I,n=7), 312.5 mg/h (dose II,n=5) and 625 mg/h (dose III, n=6) unconjugated bilirubin was given for 4 hours. Half-timeH 1 andH 2 of bilirubin uptake and conjugation were determined and compared with a control group without infusion (n=15).H 1 shows slight elevation at dose I, II and III; there are no significant differences between these doses. A significant depression ofH 2 is observed at doeses II and III. After 120 min (doses I and II) and 180 min (dose III), serumbilirubin concentration reached a maximum (highest concentration at dose III 12.6%). No significant change in concentration occurred later on.
