Comparison of microleakage of root-end filling materials – In vitro study

ObjectivesThe objective of the study was to evaluate the microleakage of various root end filling materials and to find the sealing ability of these materials.MethodologySixty (60) extracted single rooted anterior teeth were selected and divided into four groups of 15 samples each. Group A, B, C and D in which root-end filling was done with Surgical Simplex Bone Cement, Super EBA, Ketac Molar Glass Ionomer and Pro-root MTA respectively. The teeth were retrofilled and then the apical halves were submerged in 2% methylene blue dye. The depth of dye penetration and maximum value of leakage in each sample were recorded.ResultsGroup D had statistically significant difference from Group C (1.73 ± 0.16 mm) as well as Group A (2.10 ± 0.14 mm).Interpretation and conclusionMicroleakage of Group B was minimum. Thus concluding that Super EBA is a good root-end filling material.
