In vitro Comparison of the Apical Microleakage of Lateral Compaction with the Warm Vertical of 4% Tapered Gutta-Percha Obturation in Root Canal Prepared by FlexMaster Rotary System K. Nazari Moghadam DDs , K. Honardar DDs , H. Labaf DDs2 Received: 19/06/06 Sent for Revision: 28/06/06 Received Revised Manuscript: 29/04/07 Accepted: 09/05/07 Background and Objective: The success rate of root canal treatment depends on the proper execution of the final phase. Recently, various materials and techniques have been presented on the market for root canal obturation. The purpose of this study was to compare in vitro lateral condensation technique of the microleakage seal of with warm vertically-obturated single 4% tapered gutta-percha cone in root canals prepared by rotary system FlexMaster in crown-down manner. Materials and Methods: In this laboratory study the mesial root canals of 36 freshly extracted human mandibular molar teeth randomly were divided in to two groups of 15 teeth and two groups were designate as a negative and positive control respectively. After cleaning and shaping with FlexMaster rotary system, the teeth were obturated as follows: in group one, a lateral compaction technique with 2% tapered gutta-percha and in group two, obturated warm vertically (ENDOTWIN) with a single 4% tapered gutta-percha cone and AH plus endodontic sealer were applied. Nevertheless, the coronal portion and the root surface of each tooth was covered with two layers of nail varnish and a layer of sticky wax. The specimens were then immersed in blue Indian ink dye for two days, prior to sectioning by disc. Dye penetration was evaluated, and the data were analyzed with T-student test. Results: There was no significant difference between the two groups (p=0.83). The mean of dye penetration in lateral compaction group was 0/65 mm and for warm vertically compaction group was 0/61mm. Conclusion: This study showed that canals prepared with Flex Master rotary systems can be obturated with 2% taper gutta-percha plus AHPLUS root canal sealer. Thus lateral compaction could possibly be a suitable technique for root canal obturation and other requirements.
