Retreatment of Experimental Carrier-Based Obturators with the Remover NiTi Instrument: Evaluation of Apical Extrusion and Effects of New Kinematics

Figure 4

Mean values of debris apical extrusion (grams) measured for each experimental group (kinematics). In each box plot, the median value (black line), interquartile range (length of the box), and minimum and maximum values (extreme lines) are reported. °indicates outlier values. No significant differences are reported.
