| ABSTRACTBack ground: A new product of thermoplasticized obturators (thermafill and soft core) had been used instead ofcold gutta percha. The aim of this study was to measure and compare the apical and lateral extrusion of two typesof sealers (zinc oxide eugenol, apexit plus) used in cold lateral condensation, thermafill and soft core obturationmethods.Materials and methods: Fifty simulated single straight canals in clear acrylic resin blocks having lateral canals wereused. They were preprepared to resemble the root canal of the tooth, with MAF of size 40. They were divided into tengroups, each group containing 5 samples. Group 1: cold gutta percha (lateral condensation) using apexit plussealer. Group 2: cold gutta percha (lateral condensation) using zinc oxide eugenol sealer. Group 3: thermafill size 35using apexit plus. Group 4: thermafill size 35 using zinc oxide eugenol. Group 5: thermafill size 40 using apexit plussealer. Group 6: thermafill size 40 using zinc oxide eugenol sealer. Group 7: soft core obturator size 35 using apexit plussealer. Group 8: soft core size 35 using zinc oxide eugenol. Group 9: soft core size 40 using apexit plus sealer. Group10: soft core size 40 using zinc oxide eugenol sealer.Result: The groups obturated using apexit plus sealer showed higher mean of apical extrusion than groups obturatedusing zinc oxide eugenol sealer. The mean of the apical extrusion was higher in all thermoplasticized obturatorsgroups than cold gutta percha group. Thermafill group size 35 showed lower mean of lateral extrusion than soft coresize 35, 40 and lateral condensation.Conclusion: Cold gutta percha group showed the lowest mean of apical extrusion. Thermafill obturators size 35group showed the lowest mean of lateral extrusion.Key words: Apical, lateral, extrusion, sealer. (J Bagh Coll Dentistry 2009; 21(4):26-30) | ||
