Sažetak
Objectives. To compare the quality of three obturation techniques using bacterial leakage test and μCT. The correlation between two testing methods was examined. Study design. Fifty-one extracted single-root teeth were prepared with ProTaper instruments, divided into 3 groups of 15 each, and obturated: Group 1, lateral compaction/AH Plus ; Group 2, thermoplasticized Protaper gutta-percha/AH Plus ; Group 3, Protaper single-cone gutta-percha/AH Plus. Bacterial leakage of each specimen was measured during 30 days (chi-squared test), and the voids volume in root canal filling was measured using μCT (Kruskal-Wallis test). Results. More than half of specimens in each group leaked bacteria. There wasn't significant differences among the techniques using bacterial leakage test and μCT (P>.05). The bacterial leakage values and μCT scores correlated significantly (P<.05). Conclusions. The present study indicated that three tested techniques couldn't provide complete sealing of the root canal. Bacterial leakage test and μCT can be used efficaciously for the evaluation of root canal obturation.
