Aims: The aim of the present study was to compare and evaluate the sealing ability of different root end filling materials by testing their microleakage.
Methods and Material: One hundred and fifty extracted human single rooted anterior teeth were resected at an angle of 0 0 and an apical cavity of 2 mm depth was made in each root. All the specimens were divided into five groups of 30 each. The roots were then decalcified by using clearing technique.
Stastistical analysis used: The stastitical analysis was perfomed by using stereomicroscope at 10X magnification to measure dye penetration from the surface of the filling upto deepest portion of penetration.
Results: Statistical differences (P<0.0010) were seen among all the groups in the descending
order amalgam (Septalloy), glass ionomer cement (ChemFlex), cermet cement (Hidense),
compomer (Dyract) and mineral trioxide aggregate (Pro Root MTA).
Conclusions: Mineral trioxide aggregate provided best sealing ability as compared to the other
Groups. Sealing ability of the compomer was better than glass ionomer cement. Amalgam exhibited maximum microleakage as compared to the other groups.
