Comparative Evaluation of the Sealing Abilities of Different Materials as Barriers to Coronal and Apical Microleakage Using Dye Penetration Method-An In Vitro Study
Journal Title: International Journal of Medical Science and Innovative Research (IJMSIR) - Year 2017, Vol 2, Issue 5
Abstract
Introduction: The main objective of root canal filling is to obturate the entire root canal system and provide an impervious apical and coronal seal. Incomplete obturation and sealing may cause penetration of microorganisms and toxins which is a major cause of endodontic failures.Methodology: 90 recently extracted single rooted mandibular premolar teeth were collected for the study. The samples were randomly divided into 2 experimental Groups and 1 control Group, each involving 30 teeth. All the teeth were free from root defects, fractures and immature apices .All teeth were instrumented using Crown down technique with Hand NiTiProtaper files. The samples were immersed in 2% methylene blue dye for 7 days to allow dye penetration. All the samples were spilt longitudinally and visualized under Stereomicroscope at a magnification of 10X for measuring linear dye penetration.Results: The data was analysed using Student’s 't' Testat 5% level of significance and ‘Z’ Test at 5% level of significance. Conclusion:Present study concluded that Resin Composite and Resin Modified Glass Ionomer cement present better sealing ability than dental amalgam when used as post endodontic coronal restoration.
