This study was planned to study the characteristics of the curved vernical amal gam, silver glass ionomer, enhanced zinc oxide ojenol sim and low-heat injection thermoplastic grain, used in retrograde filling applications. Root channels were extended and filled. The roots ends were re-zecked and cavities were prepared for retrograde fillings. The teeth are divided into four groups of 10 teeth. Five teeth were given to negative controls and five to positive controls. In Group 1, the high-bars ratio amalgam, the silver glass ionomer in Group 2, the low-heat injected thermoplastic wheat perka and the strengthened zinc oxide ogenol in Group 4 were placed in the caves. The teeth were kept in the peanut ink for 48 hours, demineralized, transparent, and paint leakage was assessed using a stereomicroscope as Unear. The findings obtained from this study, high-perfect amalgame and silver glass ionomer in the teeth used with a curved vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical vernical. A significant degree (p<0.05) fewer apical paint leakage was shown by the A key. Keywords: retrograde filling, microsisection. ionomer cement, reinforced chain oxide eugenol and low temperature injectable thermoplasticized guttapercha when used as retrograde filling materials. The roots of fifty maxillary anterior teeth were instrumented and obturated using gutta percha and sealer. Following apical resections, retrograde cavities were prepared. Four test groups each has 10 teeth received one of the materials. After 48 hours in india ink, teeth were cleared and linear apical dye leakage was measured with a stereomicroscope.   Abstract The purpose of this study was to evaluate the sealing ability of the high copper amalgam with varnish, silver glass According to the results of ofihis study, both high copper amalgam with varmish and silver glass ionomer cement demonstrated statistically (p<0.05) less leakage than reinforced chain oxide eugenol and low temperature thermoplasticated gutta perclia. Key words : retrograde filling, microleakage.
