ABSTRACT

Aim: To measure the light transmission through different esthetic posts and to evaluate the degree of polymerization of dual cure resin cement cured through these posts. Materials and Methods: The posts were divided into two experimental groups i.e. Group A (D.T. Light post); Group B (D.T. White post) and control i.e. Group C (metal post), each group having 10 samples. Posts of each group were illuminated with curing light and photographs were taken keeping the parameters standardized to evaluate the intensity of light transmission at different levels. The degree of polymerization of dual cure resin cement was evaluated using Fourier Transform Infrared spectroscopy. The data obtained was subjected to statistical analysis. Results: D.T. Light post showed highest light transmission and degree of polymerization. The light intensity decreased from cervical to apical for both esthetic post but the decrease from middle to apical third was insignificant for D.T. White post group. No light transmission was detected in metal post but the degree of polymerization decreased significantly from cervical to middle third. Conclusion: Cementation of fibre post with superior light transmitting ability using dual cured resin cement resulted in increased degree of polymerization.
