Introduction:The successful root canal treatment is achieved by a fluid impervious seal at the coronal and apical ends. Hence we have compared the sealing ability of mineral trioxide aggregate (MTA) and glass ionomer and composite resin when used as a seal over gutta-percha. Materials & Method: Fourty extracted anterior teeth were endodontically treated. After removal of 4 mm of coronal gutta-percha, the teeth were randomly divided into four groups depending on the restorative material being placed namely: MTA, GIC and composite resin. A positive control group received no barrier. All the teeth were covered with 2 layers of sticky wax, except for the access openings. The teeth were then immersed in Indian ink for 48 hrs, decalcified, dehydrated and cleared. Microleakage into the canals was measured in millimeters using stereomicroscope. The values obtained were statistically analyzed. Results:Results showed that the MTA group provided an excellent coronal seal, followed by glass ionomer cement. Composite showed the highest amount of coronal microleakage.
