  • Title: Effect of eugenol-based root canal sealers on retention of prefabricated metal posts luted with resin cement.
    Author: Al-Ali K.
    Journal: Saudi Dent J; 2009 Jul; 21(2):69-73. PubMed ID: 23960462.
    Abstract:
    OBJECTIVE: This study evaluated the effect of two different eugenol-based root canal sealers on the retention of prefabricated metal posts luted with adhesive resin cement. MATERIALS AND METHODS: Thirty prefabricated ParaPosts randomly divided among three groups of 10 each were luted into extracted single-rooted teeth with adhesive resin cement. Two of the groups had been obturated with Gutta-Percha and one of two eugenol-based root canal sealers (Endofil and Tubli-Seal), respectively. The third group was not obturated and served as the control. The forces required for dislodgment of posts from their prepared post spaces were recorded using a universal testing machine. Data were statistically analyzed using one-way ANOVA and Tukey's multiple range test was used to determine the mean differences. RESULTS: Endofil and Tubli-Seal groups demonstrated significantly reduced retention compared to the unobturated (control) group (P < 0.05). CONCLUSION: Eugenol-based sealers significantly reduced the retention of prefabricated posts luted with adhesive resin cement.
