The Differences Results Of Root Canal Filling Between The Thermafil Technique And The Gutta Perca Lateral Condensation Technique

Abstract

The Thermafil obturation technique is relatively new. The working time and materials used in this technique are more efficient so that the thermafil obturation technique is more environmental-friendly. The objective of this study was to determine the differences of the root canal leakage between the techniques of thermafil and the lateral condensation root canal fillings. Seventy extracted single teeth straight roots were prepared with step back techniques. The diameter of the apical foramen were standardized by using number 15 file and the length of the teeth were reduced by 1 mm. The root canals were prepared until no.40 as MAC and the last file was no.55. The teeth were randomized and filled with the guttaperca thermafil and lateral condensation technique. The calculation of the leakage was measure by microscope with 30 times enlargement, and statistically analized using the Chi Square test of P<0.05. The study showed that the leakage of the guttapercha lateral condensation technique was not better than guttapercha thermafill technique. The thermafill had more leakage distance than lateral condensation technique.
