| ABSTRACTBackground: When a tooth is treated endodontically, there are several objectives, which must be met for the rootcanal therapy to be successful. One of those objectives is the complete obturation of root canal system. The purposeof this study was to evaluate the apical sealing ability of root canals prepared by hand and rotary ProTaper systemand obturrated with Thermafil and ProTaper gutta percha points in comparison with conventional cold lateralcondensation by using dye penetration method.Materials and Methods: Sixty extracted human single straight canals (premolars) were collected and these teethwere randomly divided into two groups of 30 specimens each.(Group A-rotary ProTaper, Group B-hand ProTaper),and each group were divided into three subgroups of 10 specimens each.(Group A1,B1-Thermafil,Group A2,B2-ProTaper gutta percha points, Group A3,B3 cold lateral condensation). Dorifil root canal sealer was employed as thecommon sealant.Results: The hand ProTaper was significantly better than rotary ProTaper at apical microleakage when Thermafil,ProTaper gutta-percha point and lateral condensation were used. In group A both the highest and lowest meanvalue for apical leakage were seen at lateral condensation technique (4.35) and Thermafil technique (1.35) whilethe protaper g.p points was (2.75).In group B both the highest and lowest mean value for apical leakage were seenat CLC (3.55) and Thermafil (1.1) while the protaper g.p points was (2.65).There was high statistically significantdifference between Thermafil, protaper g.p points and CLC techniques(p<0.05)Conclusion: The results of this study indicate that root canals prepared by hand protaper was significantly better thanrotary protaper at apical microleakage.The roots treated by Thermafil leak the least than protaper g.p points andCLC techniques.Key words: Apical seal, Thermafil, ProTaper gutta percha points, Lateral condensation.
