Comparison Of Marginal Seal Of MTA And Cyanoacrylate As Root End Filling Materials-An In Vitro Study

The aim of the present study was to compare the marginal seal between MTA Angelus and Cyanoacrylate when used as a root-end fillingmaterial' Thirty single-rooted maxillary central incisors were included as part of this study. Post the resection of the crowns cleaning and shaping with hand and protaper rotary files was done followed subsequently by obturation of the roots. The root ends were resected and root end cavity preparation of 3 mm depth was performed using ultrasonic tips. Root samples were then randomized into 2 groups of 15 each and restored with (1) Group 1: MTA Angelus and (2) Group 2: Cyanoacrylate. Subsequently they are coated with 2 coats of nail varnish and immersed in Methylene blue dye 2% for 48 hrs followed by longitudinal root resection. Depth of dye penetration was evaluated under the stereomicroscope to examine the extent of rnicroleakage in units of millimetres(mm). The results were then statistically analyzed using unpaired t test,Both the materials showed microleakage, however, MTA showed less microleakage with mean value of 1.3mm when compared to Cyanoacrylateat 1.6mm.
