Failure to maintain the coronal as well as apical seal may expose obturated canals to microbes that could retard healing and create infection in the periodontal ligament or supporting osseous structures. 50 single rooted teeth (Type I canal anatomy) were randomly assigned to 4 experimental and 2 control groups. Ten specimens each were sealed with Mineral Trioxide Aggregate (MTA), Tetric Flow, Glass Ionomer Cement (GIC) and Light Cure Glass Ionomer cement (LC GIC). After creation of uniform orifice diameter, the smear layer was removed and the canal systems obturated using lateral compaction of gutta-percha (GP). GP was removed to the depth of 3.5 mm, experimental materials placed in orifice and the roots submerged in Rhodamine-B dye in vacuum for one week. Specimens were longitudinally sectioned and leakage measured using a 10X stereomicroscope and graded for depth of leakage. According to the result of the present study LC GIC demonstrated significantly better seal (p<.01) than MTA however there was no statistically significant difference in leakage (p>.01) between Tetric Flow, GIC and LC GIC and in between MTA, Tetric Flow and GIC.
