The present in vitro study has been conducted to compare the apical seal of three endodontic sealers; Zinc oxide and eugenol, AH-Plus and Endoflas using dye penetration method.
The root canals of 99 extracted human maxillary central incisors were instrumented to size 55. The teeth were randomly divided into 3 experimental groups (A,B,C) and obturated with three different sealers - Zinc oxide eugenol, AH-Plus and Endoflas respectively. The teeth were immersed in 2% methylene blue solution for 24 hours and sectioned to measure the penetration of the die using Stereomicroscope. Statistical analysis was done using one way analysis of variance (ANOVA) and student's t test.
The results of ANOVA revealed that there was statistically significant difference in apical leakage between all the three groups. Pair wise comparison of three groups by student's t test showed that there was statistically significant difference in the amount of leakage between AH Plus sealer and the other two groups with Zinc oxide eugenol and Endoflas sealers. The difference in leakage observed between Zinc oxide eugenol and Endoflas was not statistically significant.
The above results clearly indicate and support the present study in proof that sealing ability of AH plus is greater than that of Zinc oxide and Endoflas sealers.
