Assessment of efficacy of apical sealing ability of gutta-percha by lateral Condensation technique and Injectable thermoplasticized gutta-percha technique (Obtura II)- A comparative study
Samriti Sharma, Satish Sharma

Background: Contemporary endodontic obturation includes thermoplasticised techniques, such as warm vertical condensation and core-carrier obturation. The present study was undertaken for evaluating and comparing the apical sealing ability of gutta-percha by lateral Condensation technique and Injectable thermoplasticized gutta-percha technique (Obtura II). Materials & methods: A total of 40 extracted maxillary canines were included and were stored in normal saline. Access opening was done and biomechanical preparation was done. Pro Taper rotary files were used to clean and shape the canals using 17% EDTA as a canal lubricant. Obturation was done according to the following groups with 20 specimens in each group: Group-A Lateral condensation obturation technique, and Group-B Injectable thermoplasticized gutta- percha obturation technique (obtura II). The roots were immersed in a sealed bottle containing 2% Methylene blue dye upto 3 mm from the apical portion of the root leaving rest of the root portion out of dye. The extent of Dye penetration was measured using Stereo microscope of 20x magnification. Results: Mean microleakage among the specimens of group A and group B was 2.63 mm and 3.12 mm respectively. While analysing statistically, non-significant results were obtained while comparing the mean microleakage among specimens of group A and group B. Conclusion: Both the obturation techniques can be used with equal efficacy in patients undergoing root canal therapy. Key words: Obturation, Gutta-percha, Condensation, Obtura II.
