title: Analysis of single point and continuous  wave of condensation root filling techniques by micro-computed tomography.
abstract: 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.
