Abstract

The in vitro quality o f the sealing ability of materials for retrograde
root fillings: amalgam, Super EBA-seal and IRM has been examined.
The root canals of thirty four single rooted teeth were treated by conventional “step-back” technique and obturated by gutta-percha and Diaket sealer using cold lateral condensation technique. The apex of the roots were resected and retrograde cavities o f Class I, 2 mm deep, were made. Three groups of 10 samples each were obturated by one o f the mentioned materials. After seven days in ink the samples underwent the “clearing ” process. The transparency of teeth was achieved by demineralization in nitric acid, dehidration in ethyl alcohol and by submerging the teeth in methyl-salicilat. The linear day penetration was measured by means o f a stereomicroscope. On the basis of the obtained results, in this study, the best retrograde sealing was achieved by using EBA-cement while amalgam and IRM showed poorer sealing ability.
