Objectives: To evaluate the apical leakage of the root canal fillings performed with RoekoSeal Automix (RSA) alone and in combined with gutta-percha electrochemically. Materials and methods: Fifty two maxillary anterior teeth were divided into two groups. In group 1, the root canals were filled with RSA alone and in group 2 the root canals were filled with gutta-percha and RSA (n=24 each group). The remaining 4 teeth were used for positive and negative control groups. An experimental cell was constructed which was connected with a constant current source. 1% potassium iodide (KI) solution was added to the cell as the electrolyte and the teeth were then immersed in this solution. Copper electrodes with 1 milliampere (mA) conductance capacity were used as anodes to complete the circuit. The results were read daily, with a digital voltmeter connected to the experimental cell, for a total of 21 days. The changes in amount of leakage from day to day within the groups were evaluated by a "t-test for dependent samples" and the difference between two groups was analyzed by "t-test for independent samples". Results: The difference of apical leakage amount between two experimental groups was not statistically significant (p>0.05). Both groups showed significant leakage at all time periods (p<0.05). Conclusion: RSA alone was not different in terms of leakage from gutta-percha compacted with RSA. However, RSA was not totally effective in preventing leakage. [ABSTRACT FROM AUTHOR] |
