Title

AN INVITRO EVALUATION OF CORONAL SEAL OF AMALGAM AND C & B METABOND AGAINST BACTERIAL MICROLEAKAGE

Pages

  134-140

Abstract

 Introduction: Improper coronal restoration after root canal therapy leads to penetration of microorganisms along root canal or through voids of root canal filling to periapical tissues and ultimate failure. The aim of this study was to evaluate the SEALing ability of AMALGAM and C&B Metabond against coronal MICROLEAKAGE of ENTROCOCCUS FAECALIS.Materials & Methods: In this experimental in vitro study, 54 premolar teeth were randomly divided to two groups of 24 teeth and for each the access cavities were prepared. The pulp chamber floorobturated with AMALGAM or C&B Metabond in two test groups, a further two groups of three teeth served as negative and positive controls. The external surface of each root, except the apical region, was covered with two layers of nail varnish. The teeth were inserted into Eppendorf plastic tubes and suspended in glass vials containing sterile BHI broth. ENTROCOCCUS FAECALIS were placed in the access of test and control groups and opacity of BHI was examined twice a week. The results were analyzed using fissure exact test and ANOVA (E=0.05).Results: Leakage was present in 13/20 of AMALGAM group; whilst 4/21 of the samples of C&B Metabondleaked at 3 months period. This difference was statistically significant and the SEALing ability of two materials was increased by time lapse (p value < 0.05).Conclusion: C&B Metabond showed better SEALing ability as a coronal SEAL than AMALGAM against Entrococous Feacalis at 3 months period and its use is advised for double SEALing before final coronal restoration.
