摘要：The aim of the present microtomographic study was to investigate the quality of root canal
filling and the voids formation in canals of extracted teeth instrumented with a simultaneous technique
and filled with two different methods. Twenty-four single-rooted teeth were assigned to two experimental
groups (no. = 12); canals were shaped with NiTi rotary files, irrigated with NaOCl and filled either with
the single point (group 1) or the continuous wave of condensation technique (group 2). Specimens underwent
microtomographic scanning. Collected data were statistically analyzed by nonparametric methods.
Void mean percentages were found to be limited and similar between the two groups; the single point
technique led to greater sealer thickness in partially oval canals.
