Distribution of RoekoSeal sealer applied by three obturation techniques

The aim of the study was to evaluate the distribution of RoekoSeal sealer using three different obturation techniques. Forty-five single-rooted extracted human teeth were prepared in a crown-down manner using ProFile instruments. After instrumentation the specimens were filled using Roekoseal Automix (RSA) on conjunction with the cold lateral condensation, Thermafil and Obtura II techniques. Each root was sectioned horizontally. Color images were obtained using a reflected-light microscope. The crosssections were assessed by microscopy for distribution of sealer. The lateral condensation technique produced significantly greater distribution of RSA (mean 9%) compared to specimens obturated with Thermafil (mean, 1.68%) (p = 0, 001) and by the Obtura II technique (mean, 4.29%) (p = 0.008).
